to prevent crimping. While securing the hoses, do not pierce or crimp the hoses.

TYPICAL INSTALLATION

FIGURE 2.

MIXING VALVE USAGE

This appliance has been design certified as complying with American

National Standard/CSA Standard for water heaters and is considered

suitable for:

Water (Potable) Heating and Space Heating: All models are

considered suitable for water (potable) heating and space heating.

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated to a

temperature which will satisfy space heating, clothes washing, dish

washing, and other sanitizing needs can scald and permanently injure

you upon contact. Some people are more likely to be permanently

injured by hot water than others. These include the elderly, children,

the infirm, or physically/mentally handicapped. If anyone using hot

water in your home fits into one of these groups or if there is a local

code or state law requiring a certain temperature water at the hot

water tap, then you must take special precautions. In addition to

using the lowest possible temperature setting that satisfies your hot

water needs, a means such as a Mixing Valve, shall be used at the hot

water taps used by these people or at the water heater. Mixing valves

are available at plumbing supply or hardware stores. Consult a Qualified

Installer or Service Agency. Follow mixing valve manufacturer’s

instructions for installation of the valves. Before changing the factory

setting on the thermostat, read the “Temperature Regulation” section in

this manual, see Figure 26.

FACTS TO CONSIDER ABOUT THE LOCATION

Carefully choose an indoor location for the new water heater, because

the placement is a very important consideration for the safety of the

occupants in the building and for the most economical use of the

appliance. This water heater is not for use in manufactured

(mobile) homes or outdoor installation.

Whether replacing an old water heater or putting the water heater in a

new location, the following critical points must be observed:

1. Select a location indoors as close as practical to the vent terminal or

location to which the water heater vent piping is going to be connected,

and as centralized with the water piping system as possible.

2. Selected location must provide adequate clearances for servicing

and proper operation of the water heater.

Installation of the water heater must be accomplished in such a manner

that if the tank or any connections should leak, the flow will not cause

damage to the structure. For this reason, it is not advisable to install

the water heater in an attic or upper floor. When such locations cannot

be avoided, a suitable drain pan should be installed under the water

heater. Drain pans are available at your local hardware store. Such

a drain pan must have a clearance of at least 1.0" (2.5cm) greater

than any point on the water heater’s outer jacket and must be piped

to an adequate drain. The pan must not restrict combustion air flow.

For example, if a circular pan is used, it must be a minimum of 27"

(69cm) in diameter. See Figure 1.

Water heater life depends upon water quality, water pressure

and the environment in which the water heater is installed. Water

heaters are sometimes installed in locations where leakage may

result in property damage, even with the use of a drain pan piped

to a drain. However, unanticipated damage can be reduced or

prevented by a leak detector or water shut-off device used in

conjunction with a piped drain pan. These devices are available

from some plumbing supply wholesalers and retailers, and detect

and react to leakage in various ways:

• Sensors mounted in the drain pan that trigger an alarm or turn off

the incoming water to the water heater when leakage is detected.

• Sensors mounted in the drain pan that turn off the water supply

to the entire home when water is detected in the drain pan.

• Water supply shut-off devices that activate based on the water

pressure differential between the cold water and hot water pipes

connected to the water heater.

• Devices that will turn off the gas supply to a gas water heater

while at the same time shutting off its water supply.

INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS

(VAPORS) ARE LIKELY TO BE PRESENT OR STORED

(GARAGES, STORAGE AND UTILITY AREAS, ETC.): Flammable

liquids (such as gasoline, solvents, propane (LP or butane, etc.)

and other substances (such as adhesives, etc.) emit flammable

vapors which can be ignited by a gas water heater’s hot surface

igniter or main burner. The resulting flashback and fire can cause

death or serious burns to anyone in the area.

Also, the water heater must be located and/or protected so it is not

subject to physical damage by a moving vehicle.

LOCATING THE NEW WATER HEATER

This water heater must not be installed directly on carpeting.

Carpeting must be protected by metal or wood panel beneath the

appliance extending beyond the full width and depth of the appliance

by at least 3" (7.6 cm) in any direction, or if the appliance is installed

in an alcove or closet, the entire floor must be covered by the panel.

Failure to heed this warning may result in a fire hazard.

Minimum clearances between the water heater and combustible

construction are 0 inch at the sides and rear, 5.5" (14.0 cm) from the front

and 12" (30.5 cm) from the top. (Standard clearance.) If clearances stated

on the heater differ from standard clearances, install water heater

according to clearances stated on the heater.

Adequate clearance 24" (61.0 cm) for servicing this appliance should

be considered before installation, such as changing the anodes, etc.

A minimum clearance of 5.5" (14.0 cm) must be allowed for access to

replaceable parts such as the thermostats, drain valve and relief valve.

When installing the heater, consideration must be given to proper location.

Location selected should be as close to the wall as practicable and as

centralized with the water piping system as possible.

FIGURE 4.

A gas water heater cannot operate properly without the correct

amount of air for combustion. Do not install in a confined area

such as a closet, unless you provide air as shown in the “Locating

The New Water Heater” section. Never obstruct the flow of

ventilation air. If you have any doubts or questions at all, call your

gas supplier. Failure to provide the proper amount of combustion

air can result in a fire or explosion and cause death, serious bodily

injury, or property damage.

FIGURE 5.

If this water heater will be used in beauty shops, barber shops, cleaning

establishments, or self-service laundries with dry cleaning equipment,

it is imperative that the water heater or water heaters be installed so

that combustion and ventilation air be taken from outside these areas.

Propellants of aerosol sprays and volatile compounds, (cleaners,

chlorine based chemicals, refrigerants, etc.) in addition to being highly

flammable in many cases, will also react to form corrosive hydrochloric

acid when exposed to the combustion products of the water heater.

The results can be hazardous, and also cause product failure.

INSULATION BLANKETS

Insulation blankets are available to the general public for external use

on gas water heaters but are not necessary with these products. The

purpose of an insulation blanket is to reduce the standby heat loss

encountered with storage tank heaters. Your water heater meets or

exceeds the Energy Policy Act standards with respect to insulation and

standby loss requirements, making an insulation blanket unnecessary.

Should you choose to apply an insulation blanket to this heater, you

should follow these instructions (For identification of components

mentioned below, see Figure 1). Failure to follow these instructions

can restrict the air flow required for proper combustion, potentially

resulting in fire, asphyxiation, serious personal injury or death.

•Do not apply insulation to the top of the water heater, as this will

interfere with safe operation of the blower assembly.

•Do not cover the outer door, thermostat or temperature & pressure

relief valve.

•Do not allow insulation to come within 2" (5.1 cm) of the floor to

prevent blockage of combustion air flow to the burner.

•Do not cover the instruction manual. Keep it on the side of the

water heater or nearby for future reference.

•Do obtain new warning and instruction labels from the manufacturer

for placement on the blanket directly over the existing labels.

•Do inspect the insulation blanket frequently to make certain it

does not sag, thereby obstructing combustion air flow.

COMBUSTION AIR AND VENTILATION FOR

APPLIANCES LOCATED IN UNCONFINED SPACES

UNCONFINED SPACE is space whose volume is not less than

50 cubic feet per 1,000 Btu per hour (4.8 cubic meters per kW) of the

aggregate input rating of all appliances installed in that space. Rooms

communicating directly with the space in which the appliances are

installed, through openings not furnished with doors, are considered

a part of the unconfined space.

In unconfined spaces in buildings, infiltration may be adequate to

provide air for combustion, ventilation and dilution of flue gases.

However, in buildings of tight construction (for example, weather

stripping, heavily insulated, caulked, vapor barrier, etc.), additional air

may need to be provided using the methods described in “Combustion

Air and Ventilation for Appliances Located in Confined Spaces.”

COMBUSTION AIR AND VENTILATION FOR

APPLIANCES LOCATED IN CONFINED SPACES

CONFINED SPACE is a space whose volume is less than 50 cubic

feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input

rating of all appliances installed in that space.

When drawing combustion air from inside a conventionally

constructed building to a confined space, such a space shall be

provided with two permanent openings. ONE WITHIN 12 INCHES (30

cm) OF THE ENCLOSURE TOP AND ONE WITHIN 12 INCHES (30 cm)

OF THE ENCLOSURE BOTTOM. Each opening shall have a free area

of one square inch per 1000 Btu/hr (22 cm2/kW) of the total input of

all appliances in the enclosure, but not less than 100 square inches

(645 cm2).

If the confined space is within a building of tight construction, air for

combustion and ventilation must be obtained from outdoors. When

directly communicating with the outdoors or communicating through

vertical ducts, two permanent openings, located in the above manner,

shall be provided. Each opening shall have a free area of not less

than one square inch per 4000 Btu/hr (5.5 cm2/kW) of total input of all

appliances in the enclosure. If horizontal ducts are used, each opening

shall have a free area of not less than one square inch per 2000 Btu/

hr (11cm2/kW) of the total input of all appliances in the enclosure.

A. ALL AIR FROM INSIDE BUILDINGS: (See Figure 5 and 6)

The confined space shall be provided with two permanent openings

communicating directly with an additional room(s) of sufficient volume

so that the combined volume of all spaces meets the criteria for an

unconfined space. The total input of all gas utilization equipment installed

in the combined space shall be considered in making this determination.

Each opening shall have a minimum free area of one square inch per

1,000 Btu per hour (22 cm2/kW) of the total input rating of all gas utilization

equipment in the confined space, but not less than 100 square inches

(645 cm2). One opening shall commence within 12 inches

(30 cm) of the top and one commencing within 12 inches (30 cm) of the

bottom of the enclosures.

FIGURE 6.

B. ALL AIR FROM OUTDOORS: (See Figures 7, 8 and 9)

The confined space shall be provided with two permanent openings,

one commencing within 12 inches (30 cm) of the top and one

commencing within 12 inches (30 cm) from the bottom of the

enclosure. The openings shall communicate directly, or by ducts,

with the outdoors or spaces (crawl or attic) that freely communicate

with the outdoors.

1. When directly communicating with the outdoors, each opening shall

have a minimum free area of 1 square inch per 4,000 Btu per hour

(5.5 cm2/kW) of total input rating of all equipment in the enclosure,

see Figure 7.

FIGURE 7.

2. When communicating with the outdoors through vertical ducts, each

opening shall have a minimum free area of 1 square inch per 4,000

Btu per hour (5.5 cm2/kW) of total input rating of all equipment in the

enclosure, see Figure 8.

3. When communicating with the outdoors through horizontal ducts,

each opening shall have a minimum free area of 1 square inch per

2,000 Btu per hour (11 cm2/kW)) of total input rating of all equipment

in the enclosure, see Figure 9.

FIGURE 8.

4. When ducts are used, they shall be of the same cross-sectional

area as the free area of the openings to which they connect. The

minimum short side dimension of rectangular air ducts shall not be

less than 3 inches (7.6 cm), see Figure 9.

FIGURE 9.

5. Alternatively a single permanent opening may be used when

communicating directly with the outdoors, or with spaces that freely

communicate with the outdoors. The opening shall have a minimum

free area of 1 square inch per 3,000 BTU per hour (8.3 cm2/kW) of

total input rating of all equipment in enclosure. See Figure 9A.

FIGURE 9A.

6. Louvers and Grilles: In calculating free area, consideration shall be

given to the blocking effect of louvers, grilles or screens protecting

openings. Screens used shall not be smaller than 1/4 inch (6.4 mm)

mesh. If the free area through a design of louver or grille is known,

it should be used in calculating the size opening required to provide

the free area specified. If the design and free area is not known, it

may be assumed that wood louvers will be 20-25 percent free area

and metal louvers and grilles will have 60-75 percent free area.

Louvers and grilles shall be fixed in the open position or interlocked

with the equipment so that they are opened automatically during

equipment operation.

7. Special Conditions Created by Mechanical Exhausting or

Fireplaces: operation of exhaust fans, ventilation systems, clothes

dryers or fireplaces may create conditions requiring special

attention to avoid unsatisfactory operation of installed gas

utilization equipment.

Water supply systems may, because of such events as high line pressure,

frequent cut-offs, the effects of water hammer among others, have

installed devices such as pressure reducing valves, check valves, back

flow preventers, etc. to control these types of problems. When these

devices are not equipped with an internal by-pass, and no other measures

are taken, the devices cause the water system to be closed. As water is

heated, it expands (thermal expansion) and closed systems do not allow

for the expansion of heated water.

The water within the water heater tank expands as it is heated and increases

the pressure of the water system. If the relieving point of the water heater’s

temperature-pressure relief valve is reached, the valve will relieve the

excess pressure. The temperature-pressure relief valve is not intended

for the constant relief of thermal expansion. This is an unacceptable

condition and must be corrected.

It is recommended that any devices installed which could create a closed

system have a by-pass and/or the system have an expansion tank to

relieve the pressure built by thermal expansion in the water system.

Expansion tanks are available for ordering through a local plumbing

contractor. Contact the local water supplier and/or a service agency for

assistance in controlling these situations.

NOTE: To protect against untimely corrosion of hot and cold

water fittings, it is strongly recommended that di-electric unions

or couplings be installed on this water heater when connected

to copper pipe.

All gas piping must comply with local codes and ordinances or with the National

Fuel Gas Code (ANSI Z223.1/ NFPA-54) or the Natural Gas and Propane

Installation Code (CAN/CSA B149.1) whichever applies. Copper and brass

tubing and fittings (except tin lined copper tubing) shall not be used.

FIGURE 10.

CHEMICAL VAPOR CORROSION

CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF

AIR FOR COMBUSTION CONTAINS CERTAIN CHEMICAL VAPORS. SUCH

CORROSION MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION.

Spray can propellants, cleaning solvents, refrigerator and air

conditioning refrigerants, swimming pool chemicals, calcium and

sodium chloride (water softener salt), waxes, and process chemicals

are typical compounds which are potentially corrosive.

Do not store products of this sort near the heater. Also, air which is

brought in contact with the heater should not contain any of these

chemicals. If necessary, uncontaminated air should be obtained from

remote or outside sources. The limited warranty is voided when failure

of water heater is due to a corrosive atmosphere. (See limited warranty

for complete terms and conditions).

WATER PIPING

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated to a

temperature which will satisfy space heating, clothes washing, dish

washing, cleaning and other sanitizing needs can scald and permanently

injure you upon contact. Some people are more likely to be permanently

injured by hot water than others. These include the elderly, children, the

infirm, or physically/mentally handicapped. If anyone using hot water in

your home fits into one of these groups or if there is a local code or

state law requiring a certain temperature water at the hot water tap,

then you must take special precautions. In addition to using the lowest

possible temperature setting that satisfies your hot water needs, a means

such as a *mixing valve, shall be used at the hot water taps used by

these people or at the water heater, see Figure 2. Valves for reducing

point of use temperature by mixing cold and hot water are also available:

Consult a Qualified Installer or Service Agency. Follow manufacturer’s

instructions for installation of the valves. Before changing the factory

setting on the thermostat, read the “Temperature Regulation” section

in this manual.

This water heater shall not be connected to any heating systems or

component(s) used with a non-potable water heating appliance.

All piping components connected to this unit for space heating applications

shall be suitable for use with potable water.

Toxic chemicals, such as those used for boiler treatment shall not be

introduced into this system.

When the system requires water for space heating at temperatures higher

than required for domestic water purposes, a tempering valve must be

installed. Please refer to Figure 2 for suggested piping arrangement.

INSTALLING THE NEW WATER HEATER

Figure 10 shows the typical attachment of the water piping to the

water heater. The water heater is equipped with 3/4 inch NPT

water connections.

NOTE: If using copper tubing, solder tubing to an adapter before

attaching the adapter to the water heater connections. Do not

solder the water lines directly to the water heater connections.

It will harm the dip tube and damage the tank.

T & P Valve and Pipe Insulation (if supplied)

Remove insulation for T & P valve and pipe connections from carton.

FIGURE 11.

Fit pipe insulation over the incoming cold water line and the hot water

line. Make sure that the insulation is against the top cover of the heater.

Fit T & P valve insulation over valve. Make sure that the insulation

does not interfere with the lever of the T & P valve.

Secure all insulation using tape.

TEMPERATURE-PRESSURE RELIEF VALVE

This heater is provided with a properly certified combination

temperature - pressure relief valve by the manufacturer.

The valve is certified by a nationally recognized testing laboratory

that maintains periodic inspection of production of listed equipment of

materials as meeting the requirements for Relief Valves for Hot Water

Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements

of ASME.

If replaced, the valve must meet the requirements of local codes, but

not less than a combination temperature and pressure relief valve

certified as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to exceed

the marked hydrostatic working pressure of the water heater

(150 psi = 1,035 kPa) and a discharge capacity not less than the

water heater input rate as shown on the model rating plate.

For safe operation of the water heater, the relief valve must not be

removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly into

the fitting of the water heater designed for the relief valve. Position

the valve downward and provide tubing so that any discharge will exit

only within 6 inches (15.2 cm) above, or at any distance below the

structural floor. Be certain that no contact is made with any live

electrical part. The discharge opening must not be blocked or reduced

in size under any circumstances. Excessive length, over 30 feet (9.14

m), or use of more than four elbows can cause restriction and reduce

the discharge capacity of the valve, see Figures 10 or 14.

No valve or other obstruction is to be placed between the relief valve

and the tank. Do not connect tubing directly to discharge drain unless

a 6" (15.2 cm) air gap is provided. To prevent bodily injury, hazard to

life, or property damage, the relief valve must be allowed to discharge

water in quantities should circumstances demand. If the discharge

pipe is not connected to a drain or other suitable means, the water

flow may cause property damage.

The Discharge Pipe:

•Shall not be smaller in size than the outlet pipe size of the valve, or

have any reducing couplings or other restrictions.

•Shall not be plugged or blocked.

•Shall be of material listed for hot water distribution.

•Shall be installed so as to allow complete drainage of both the

temperature-pressure relief valve, and the discharge pipe.

•Shall terminate at an adequate drain.

•Shall not have any valve between the relief valve and tank.

The temperature-pressure relief valve must be manually operated at least

once a year. Caution should be taken to ensure that (1) no one is in front

of or around the outlet of the temperature-pressure relief valve discharge

line, and (2) the water manually discharged will not cause any bodily

injury or property damage because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset and

continues to release water, immediately close the cold water inlet to

the water heater, follow the draining instructions, and replace the

temperature-pressure relief valve with a new one.

Make sure the gas supplied is the same type listed on the model rating

plate. The inlet gas pressure must not exceed 14 inch water column (3.5

kPa) for natural and propane gas (L.P.). The minimum inlet gas pressure

shown on the rating plate is that which will permit firing at rated input.

All gas piping must comply with local codes and ordinances or with the

National Fuel Gas Code (ANSI Z223.1/ NFPA-54) or the Natural Gas and

Propane Installation Code (CAN/CSA B149.1) whichever applies. Copper

and brass tubing and fittings (except tin lined copper tubing) shall not be used.

If the gas control valve is subjected to pressures exceeding 1/2 psi

(3.5 kPa), the damage to the gas control valve could result in a fire

or explosion from leaking gas.

If the main gas line Shut-off serving all gas appliances is used, also

turn “off” the gas at each appliance. Leave all gas appliances shut

“off” until the water heater installation is complete.

A gas line of sufficient size must be run to the water heater. Consult

the current edition of National Fuel Gas Code (ANSI Z223.1/NFPA

54) or the Natural Gas and Propane Installation Code (CAN/CSA

B149.1) and your gas supplier concerning pipe size.

There must be:

• A readily accessible manual shut off valve in the gas supply line

serving the water heater, and

• A drip leg (sediment trap) ahead of the gas control valve to help

prevent dirt and foreign materials from entering the gas control valve.

• A flexible gas connector or a ground joint union between the shut

off valve and control valve to permit servicing of the unit.

Be sure to check all the gas piping for leaks before lighting the water

heater. Use a soapy water solution, not a match or open flame.

Rinse off soapy solution and wipe dry.

This heater is approved for operation up to 5,300 feet (1,615 m) without

alteration. High altitude models are available from the factory for elevations

between 5,300 feet (1,615 m) and 10,100 feet (3,079 m). For elevations

above 10,100 feet (3,079 m) the input rating should be reduced at the rate of

4 percent for each 1,000 feet (305 meters) above sea level which requires

replacement of the burner orifice in accordance with National Fuel Gas Code

(ANSI Z223.1/NFPA 54) or the Natural Gas and Propane Installation Code

(CAN/CSA B149.1). Contact your local gas supplier for further information.

Failure to replace the standard orifice with a high altitude orifice when

installed above 10,100 feet (3,079 m) could result in improper and inefficient

operation of the appliance, producing carbon monoxide gas in excess of

safe limits, which could result in serious injury or death. Contact your gas

supplier for any specific changes which may be required in your area.

Use pipe joint compound or teflon tape marked as being resistant to

the action of petroleum [Propane (L.P.)] gases.

The appliance and its gas connection must be leak tested before

placing the appliance in operation.

The appliance and its individual Shut-off valve shall be disconnected from

the gas supply piping system during any pressure testing of that system at

test pressures in excess of 1/2 pound per square inch (3.5 kPa). It shall be

isolated from the gas supply piping system by closing its individual manual

Shut-off valve during any pressure testing of the gas supply piping system

at test pressures equal to or less than 1/2 pound per square inch (3.5 kPa).

Connecting the gas piping to the gas control valve of the water heater can

be accomplished by either of the two methods shown in Figures 12 and 13.

FIGURE 12. GAS PIPING WITH

FLEXIBLE CONNECTOR.

FIGURE 13. GAS PIPING WITH ALL

BLACK IRON PIPE TO GAS CONTROL.

SEDIMENT TRAPS

A sediment trap shall be installed as close to the inlet of the water

heater as practical at the time of water heater installation. The

sediment trap shall be either a tee fitting with a capped nipple in the

bottom outlet or other device recognized as an effective sediment

trap. If a tee fitting is used, it shall be installed in conformance with

one of the methods of installation shown in Figures 12 and 13.

Contaminants in the gas lines may cause improper operation of the

gas control valve that may result in fire or explosion. Before attaching

the gas line be sure that all gas pipe is clean on the inside. To trap

any dirt or foreign material in the gas supply line, a drip leg

(sometimes called a sediment trap) must be incorporated in the

piping. The drip leg must be readily accessible. Install in accordance

with the “Gas Piping” section. Refer to the current edition of the

National Fuel Gas Code (ANSI Z223.1/NFPA 54) or the Natural

Gas and Propane Installation Code (CAN/CSA B149.1).

FIGURE 14.

FILLING THE WATER HEATER

Never use this water heater unless it is completely full of water. To prevent

damage to the tank, the tank must be filled with water. Water must flow from

the hot water faucet before turning “ON” gas to the water heater.

To fill the water heater with water:

1. Close the water heater drain valve by turning the handle to the right

(clockwise). The drain valve is on the lower front of the water heater.

2. Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when

the water heater is in use.

3. To insure complete filling of the tank, allow air to exit by opening the

nearest hot water faucet. Allow water to run until a constant flow is

obtained. This will let air out of the water heater and the piping.

4. Check all water piping and connections for leaks. Repair as needed.

VENT PIPE ASSEMBLY

There are three parts of the vent pipe assembly that connect the water

heater exhaust (located on the lower back side of the water heater) to

the inlet of the blower assembly (mounted on top of the water heater) as

shown in Figure 1. These parts will need to be assembled according to

the instructions in the VENT PIPE PREPARATION section of this manual.

These PVC parts should be assembled with ASTM D-2564 grade cement.

Assemble Vent Pipe Assemblies #1, #2 and #3 (See Figure 1) prior

to cementing. The preferred orientation of Vent Pipe Assembly #1

(Condensate U-Assembly) is shown in Figure 16. However this

assembly may be rotated to a different orientation as needed for the

specific installation requirements. Note the rotational orientation of

each part by marking a line several inches long across the joints.The

long tube of Vent Pipe Assembly #2 should be approximately vertical.

If it is found that either of the two pieces of pipe in Vent Pipe Assembly

#2 are too long for proper fit-up, then remove as little material as

possible to improve the fit-up. Keep in mind that the pipes will insert

slightly further into the elbows when cement is applied as it acts as

a lubricating agent. The vertical distance from the bottom of the

Condensate U-Assembly to the floor that supports the water heater

should be approximately 0.25" (0.64 cm), see Figure 16. Disassemble

the parts and cement back together using the alignment marks. After

the cement dries, attach the assembly to the blower and the water

heater exhaust using the supplied rubber boots and hose clamps.

A condensate trap is incorporated in the bottom of this vent pipe assembly.

See the CONDENSATE section of this manual for further details.

VENTING

VENT PIPE TERMINATION

The first step is to determine where the vent pipe will terminate. See

Figures 15, 20 and 21. The vent may terminate through a sidewall

as shown in Figure 20 or through the roof as shown in Figure 21.

The vent system must terminate so that proper clearances are

maintained as cited in local codes or the current edition of the National

Fuel Gas Code, (ANSI Z223.1, 12.9.1 through 12.9.4) or the Natural

Gas and Propane Installation Code (CAN/CSA-B149.1).

Instructions on proper installation through a sidewall are provided

in Figure 15.

Plan the vent system layout so that proper clearances are

maintained from plumbing and wiring.

Vent pipes serving power vented appliances are classified by

building codes as "vent connectors". Required clearances from

combustible materials must be provided in accordance with

information in this manual under LOCATING THE NEW WATER

HEATER and INSTALLING THE WATER HEATER, and with the

National Fuel Gas Code and local codes.

PLANNING THE VENT SYSTEM

Plan the route of the vent system from the discharge of the blower to

the planned location of the vent terminal.

1. Layout total vent system to use a minimum of vent pipe and elbows.

2. This water heater is capable of venting flue gases equivalent to 25'

(7.6 m) of 2" pipe, 65' (19.8 m) of 3" pipe, or 128' (39.0 m) of 4" pipe

as listed in Table 1.

TABLE 1

Number of 2" Maximum 3" Maximum 4" Maximum

90° Elbows Pipe - ft. (m) Pipe - ft. (m) Pipe - ft. (m)

1 20 (6.1) 60 (18.3) 120 (36.6)

2 15 (4.6) 55 (16.8) 112 (34.1)

3 10 (3.0) 50 (15.2) 104 (31.7)

4 -- 45 (13.7) 96 (29.3)

5 -- 40 (12.2) 88 (26.8)

6 -- 35 (10.7) 80 (24.3)

The minimum vent lengths for each of the pipe sizes is one 90° on top

of the unit plus 2' (61 cm) of straight pipe and the appropriate termination.

NOTE: The equivalent feet (m) of pipe listed above are exclusive of

the termination. That is, the termination, with an installed screen, is

assumed to be in the system and the remainder of the system must

not exceed the lengths discussed above.

3. The blower discharge adapter is made to accept only straight

sections of 2" pipe. To start, a minimum of 2 inches (5.1 cm) of 2"

pipe must be attached to the blower discharge, see Figure 17.

If using 2" inch vent pipe:

A minimum of 2 inches (5.1 cm) must be attached to the blower

before the first elbow. After the first elbow add the additional

venting required for the installation. The total system cannot

exceed the lengths discussed above, where each elbow is

equal to 5 feet (1.5 m) of straight pipe.

If using 3" or 4" inch vent pipe:

Two inches (5.1 cm) of pipe must be attached to the blower discharge

before adding a reducer to acquire the desired pipe diameter. An

appropriately sized 45 degree elbow (supplied locally-a schedule 40

DWV) vent terminal must be obtained with an equivalent screen (supplied

in vent kit). The total system cannot exceed the equivalent pipe lengths

discussed above where each elbow is equal to 5 feet (1.5 m) of

straight pipe (3" vent pipe) or 8 feet (2.4 m) of straight pipe (4" vent pipe).

U.S. Installations

NOTE: This unit can be vented with PVC pipe materials (Cellular Core

ASTM-F891; DWV ASTM-D2665 or CSA B181.2; Schedule 40, 80, 120

ASTM-D1785 or CSA B137.3; or SDR Series ASTM-D2241 or CSA B137.3),

CPVC pipe materials (CPVC41 ASTM-D2846 or CSA B137.6; Schedule

40, 80 ASTM-F441 or CSA B137.6; or SDR Series ASTM-F442), ABS pipe

materials (Schedule 40 DWV ASTM-D2661 or CSA B181.1 or Schedule

40 DWV Cellular Core ASTM-F628). The fittings, other than the TERMINATION

should be equivalent to PVC-DWV fittings meeting ASTM D-2665 (Use CPVC

fittings, ASTM F-438 for CPVC pipe and ABS fittings, ASTM D-2661/3311 for

ABS pipe). If CPVC or ABS pipe and fittings are used, then the proper cement

must be used for all joints, including joining the pipe to the Termination (PVC

Material). If local codes do not allow the use of the PVC termination when a

material other than PVC is used for venting, then an equivalent fitting of that

material may be substituted if the screen in the PVC terminal is removed

and inserted into the new fitting.

PVC Materials should use ASTM D-2564 Grade Cement; CPVC Materials

should use ASTM F-493 Grade Cement and ABS Materials should use

ASTM D-2235 Grade Cement.

Canadian Installation of this water heater must comply with CAN/CSA

B149.1 - Natural Gas and Propane Installation Code which requires

the vent system components be certified to ULC S636.

This water heater has been design certified to be vented with PVC

pipe certified and marked as complying with ULC S636. This water

heater is supplied with a 2 inch 22.5 degree termination elbow that is

a special fitting that must be used with this appliance. Any outlet

piping, fittings and glue used to vent this appliance that is not supplied

by the manufacturer must comply with the ULC S636 requirements.

If the water heater is being installed as a replacement for an existing power

vented heater in pre-existing venting, a thorough inspection of the existing

venting system must be performed prior to any installation work. Verify that

the correct material as detailed above has been used, and that the minimum

or maximum vent lengths and terminal location as detailed in this manual

have been met. Carefully inspect the entire venting system for any signs of

cracks or fractures, particularly at the joints between elbows and other

fittings and the straight runs of vent pipe. Check the system for signs of

sagging or other stresses in the joints as a result of misalignment of any

components in the system. If any of these conditions are found, they must

be corrected in accordance with the venting instructions in this manual

before completing the installation and putting the water heater into service.

NOTE: A. For water heaters in locations with high ambient temperatures

(above 100°F) it is recommended that CPVC or ABS pipe and fittings be used.

B. A 22.5 degree elbow (2" vent pipe) or a 45 degree elbow (3" and 4" vent

pipe) with an installed screen VENT TERMINAL must be used in all cases.

4. There will be some installations where condensate will be formed

in the horizontal runs of the vent system. This condensate will run

into the condensate boot attached to the blower and out the fitting.

The water heater is shipped with condensate hose that attaches to

the fitting on the condensate boot. No other Tee or fitting is required.

See Figures 17, 20 and 21.

CONDENSATE

This water heater is a condensing unit and requires a drain to be located

in close proximity to allow the condensate to drain safely. The condensate

drains from the unit at the exhaust tee located at the bottom of the unit

(see figure 16) and from two places on the blower assembly (see figure

17). Condensate from this water heater is mildly acidic. Please note that

some local codes require that condensate is treated by using a pH

neutralizing filter prior to disposal.

NOTE: It is important that the condensate hose on the bottom of the unit is

not installed elevated above the clamp that is secured to the side of the

jacket, see figure 16. This must be true for the entire length of the hose

from the clamp to the exit into an appropriate drain. If these instructions are

not followed or if the condensate hose is blocked, water will spill from the

condensate trap. As with every water heater installation, a drain pan

should be used to prevent water damage to the surrounding area. If

necessary, a condensate pump with an incorporated reservoir may be

used to pump the water to an appropriate drain. To avoid condensate

spillage, select a pump with an overflow switch.

Caution must be used to ensure that the drain is free and clear of

debris and will not allow backflow through the condensate hose.

Consideration must be given to avoid freezing of the condensate lines

which could result in excessive build up of condensate inside the water

heater. Waterproof heat tape may be required to prevent freezing of the

condensate lines. Please ensure that the outlet of the condensate drain

does not create a slippery condition which could lead to personal injury.

The condensate trap may be primed by filling the CONDENSATE U-

ASSEMBLY with tap water using the supplied hose while the water

heater is not operating. The system is fully primed when the hose is

lowered below the hose clamp on the side of the water heater and

water begins to flow out of the hose. In most installations the water

heater will self-prime the condensate trap during the first full heat-

up cycle. If a sound of air bubbling through water (gurgling) is heard

while the blower is operating after the first heat-up cycle, then turn

the unit off and contact your plumber or service representative.

If these instructions are not followed, the condensate build-up will

block the exhaust outlet, which will cause improper operation.

CONDENSATE SYSTEM - FIGURE 16

Condensate is likely to form in the venting system attached to this water

heater. The vent pipe should be sloped downward away from the blower

assembly (not less than 1/8" (3.2 mm) nor greater than 1/2" (12.7 mm)

per foot (30 cm) maximum). If the vent piping is vented level or sloped

upwards away from the blower assembly, then adequate means for

draining and disposing of the condensate needs to be made by the

installer. In either case, a 3/8" drain hose should be connected to the

built-in drain port. Prior to operating the water heater, make sure the

removable cap is installed on the second drain port, see Figure 17.

BLOWER ASSEMBLY INSTALLATION

1. This power vented water heater comes with the blower assembly installed.

2. After the unit is set in place, make sure the blower assembly is

still mounted securely. Also make sure that one of the drain

ports of the rubber boot vent adapter is capped off. Lastly, make

sure there is no damage to the blower.

3. Condensate drains from two locations on the blower assembly as

shown in figure 17. A condensate hose must be secured to form a

"trap" as shown in figure 17 for these condensate drain connections.

These two hoses may be connected together. The hose(s) should

be routed to a suitable drain. A fitting that may be used to join the

two hoses from the blower assembly is included in a supplied kit.

FIGURE 17.

4. Make sure there is no packing material in the inlet or discharge

of the blower.

5. Make sure that the plastic tubing is still attached from the air

pressure switch to the port on the blower housing. Make sure

the plastic tubing is not folded anywhere between the pressure

switch and the blower housing.

6. Make sure the ON/OFF switch is in the OFF position and that the

outer harness is connected from the blower control box to the

connector on the bottom side of the gas valve.

7. If the outer harness is not factory installed, make sure the ON/

OFF switch is in the OFF position and then connect the outer

harness from the blower control box to the connector on the

bottom side of the gas valve.

8. Do not plug in power cord until vent system is completely installed.

The Power Vent operates on 110-120 Vac. therefore a grounded

outlet must be within reach of the 6 foot (1.8 m) flexible power

cord supplied with the vent (See Figure 1). The power cord

supplied may be used on a unit only where local codes permit.

If local codes do not permit use of flexible power supply cord:

A. Make sure the unit is unplugged from the wall outlet. Remove

the plastic top cap. Remove screws and open panel on the

front of the control box on the blower.

B. Cut the flexible power cord, leaving enough to be able to make

connections. Remove the strain relief fitting from the box.

C. Install a suitable conduit fitting inside the enclosure.

D. Splice field wiring into existing wiring using code authorized

method (wire nuts, etc).

E. Be certain that neutral and line connections are not reversed

when making these connections.

F. Ground heater properly. This water heater must be grounded

in accordance with the National Electrical Code NFPA 70 or

the Canadian Electrical Code C22.1 and/or local codes. These

must be followed in all cases.

The water heater must be connected to a grounded metal,

permanent wiring system; or an equipment grounding

conductor must be run with the circuit conductors and

connected to the equipment grounding terminal or lead on

the water heater, see Figure 19.

G. Close the panel on the control box. Make sure that the access

panel is secured shut.

9. The blower discharge boot is made to accept only straight sections

of 2" pipe. To start off with an elbow, a short section of the furnished

pipe, a minimum of 2 inches (5.1 cm), must be cut and glued into

the end of the elbow that will mount on the discharge boot.

INSTALLATION OF VENT SYSTEM

Before beginning installation of piping system thoroughly read the

section of this manual VENT PIPE PREPARATION.

If you are installing your system so that it vents through roof, please

refer to section titled INSTALLATION OF VERTICAL VENT SYSTEM.

VENT TERMINAL INSTALLATION, SIDEWALL

1. Install the vent terminal by using the cover plate as a template to

mark the hole for the vent pipe to pass through the wall. BEWARE

OF CONCEALED WIRING AND PIPING INSIDE THE WALL.

CAUTION

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND

DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.

POWER VENT WIRING SCHEMATIC - FIGURE 19.

2. If the Vent Terminal is being installed on the outside of a finished wall, it

may be easier to mark both the inside and outside wall. Align the holes

by drilling a hole through the center of the template from the inside

through to the outside. The template can now be positioned on the

outside wall using the drilled hole as a centering point for the template.

3. A) MASONRY SIDE WALLS

Chisel an opening approximately one half inch (1.3 cm) larger than

the marked circle.

B) WOODEN SIDE WALLS

Drill a pilot hole approximately one quarter inch (0.64 cm) outside of

the marked circle. This pilot hole is used as a starting point for a

saws-all or sabre saw blade. Cut around the marked circle staying

approximately one quarter inch (0.64 cm) outside of the line. (This

will allow the vent to easily slide through the opening. The resulting

gap will be covered up by the Vent Terminal cover plate.) Repeat this

step on inside wall if necessary.

SEQUENCE OF INSTALLATIONS, FIGURE 18

Cut a length of PVC pipe about 3.5 inches (8.9 cm) longer than the wall

thickness at the opening. Glue the vent terminal to this section of pipe. Slide

the wall plate over the pipe to stop against the vent terminal. Place a bead of

caulking (not supplied) around the gap between the pipe and cover plate. Apply

enough to fill some of the gap between the pipe and wall. Place some of the

caulking on the back of the plate to hold it against the wall after installation. If the

vent pipe is installed up to the wall, with a coupling on the end against the wall

opening, the pipe with the vent terminal can be prepared for gluing before

inserting through the wall. Slide the pipe through the wall and insert into the

coupling on the other side of the wall, making sure that the vent terminal ends

up pointed in the correct position, see Figure 18.

VENT TERMINATION - FIGURE 18.

INSTALLATION OF VENT SYSTEM, SIDEWALL

With the route of the venting system and selection of materials completed,

as discussed in the section of this manual titled PLANNING THE VENT

SYSTEM, the through the wall vent terminal in place and the first section

of piping, up to first elbow, installed at the blower it is time to complete

the installation of the venting system for the sidewall installation.

FIGURE 20

Before completing the installation of the venting system be sure to read

the sections of this manual discussing the proper method of cutting

and cementing PVC pipe and fittings: VENT PIPE PREPARATION.

It is recommended that the completion of the venting system start at

the blower assembly and run to the coupling on the inside wall of

the vent terminal, Figure18.

The vent system piping should be supported every 5 feet (1.5 m)

of vertical run and every 3 feet (91 cm) of horizontal run. All piping

and fittings must be joined by the proper procedures as described

under: VENT PIPE PREPARATION.

INSTALLATION OF VERTICAL VENT SYSTEM

A proper flashing or "BOOT" should be used to seal the pipe where

it exits the roof. The total vent system should not exceed the

equivalent feet of pipe as listed in Table 1.

Provide support for all pipe protruding through the roof. All piping

should be properly secured. The vent system piping should be

supported every 5 feet (1.5 m) of vertical run and every 3 feet (91

cm) of horizontal run. All piping and fittings must be joined by the

proper procedures as described under: VENT PIPE

PREPARATION.

FIGURE 21

IMPORTANT

The vent system must terminate so that proper clearances are

maintained as cited in local codes or the current edition of the

National Fuel Gas Code (ANSI Z223.1) or the Natural Gas and

Propane Installation Code (CAN/CSA-B149.1) and as listed below:

1. Vent Termination must extend a minimum of 18 inches (46 cm) above

roof or 18 inches (46 cm) above the anticipated snow level to prevent

blockage of the vent termination, as shown in Figures 20 and 21.

2. The venting system shall terminate at least four (4) feet (1.2 m)

from or one (1) foot (30 cm) above any gable, dormer or other

roof structure with building interior access; i.e., vent, window, etc.

3. The venting system shall terminate three (3) feet (91 cm)

above any forced air inlet located within ten feet (3.0 m).
