WARNING

For indoor installations, as an additional

measure of safety, National Combustion Co.

strongly recommends installation of suitable

Carbon Monoxide detectors in the vicinity of this

appliance and in any adjacent occupied spaces.

AVERTISSEMENT

Pour des installations intérieures, National

Combustion Co. recommande fortement, comme

mesure de sécurité supplémentaire, l’installation

de détecteurs de monoxyde de carbone adaptés

dans le voisinage de l’appareil et dans chacune

des pièces habitées adjacentes.

2.A Combustion Air

Brute Deluxe boilers and water heaters must

have provisions for combustion and ventilation air in

accordance with the applicable sections addressing

requirements for air for combustion and ventilation of

the National Fuel Gas Code, ANSI Z223.1. In Canada,

the applicable sections of the Natural Gas and Propane

Installation Code (CSA B149.1) must be followed. In

all cases any and all applicable local installation codes

must also be followed.

A Brute Deluxe appliance may receive

combustion air from the space in which it is installed,

or it can be ducted directly to the unit from the outside.

Proper ventilation air must be provided in either case.

2.A.1 Combustion Air From Room

In the United States, the most common

requirements specify that the space shall communicate

with the outdoors in accordance with method 1 or 2,

which follow. Where ducts are used, they shall be of

the same cross-sectional area as the free area of the

openings to which they connect.

Method 1: Two permanent openings, one

commencing within 12 inches (30 cm) of the top

and one commencing within 12 inches (30 cm) of

the bottom, of the enclosure shall be provided. The

openings shall communicate directly, or by ducts,

with the outdoors or spaces that freely communicate

with the outdoors. When directly communicating

with the outdoors, or when communicating to the

outdoors through vertical ducts, each opening shall

have a minimum free area of 1 square inch per 4000

Btu/hr (5.5 square cm/kW) of total input rating of all

equipment in the enclosure. When communicating to the

outdoors through horizontal ducts, each opening shall

have a minimum free area of not less than 1 square inch

per 2000 Btu/hr (11 square cm/kW) of total input rating

of all equipment in the enclosure. Table 1 shows data for

this sizing method, for each Brute Deluxe model.

Method 2: One permanent opening, commencing

within 12 inches (30 cm) of the top of the enclosure,

shall be permitted. The opening shall directly

communicate with the outdoors or shall communicate

through a vertical or horizontal duct to the outdoors

or spaces that directly communicate with the outdoors

and shall have a minimum free area of 1 square inch

per 3000 Btu/hr (7 square cm/kW) of the total input

rating of all equipment located in the enclosure. This

opening must not be less than the sum of the areas of

all vent connectors in the conned space.

Other methods of introducing combustion and

ventilation air are acceptable, providing they conform

to the requirements in the applicable codes listed

above.

In Canada, consult local building and safety

codes or, in absence of such requirements, follow CSA

B149.1, the Natural Gas and Propane Installation Code.

2.B Venting

2.B.1 Vent Categories

Depending upon desired Brute Deluxe venting,

it may be considered a Category I or a Category III

appliance. In general, a vertical vent system will be

a Category I system. However, in rare instances, a

Brute Deluxe’s vertical vent system may be considered

Category III. In the U.S., the National Fuel Gas Code

(ANSI Z223.1), or in Canada the Natural Gas and

Propane Installation Code (CSA B149.1), denes a

Category I vent system, and includes rules and tables

to size these vent systems. If the Brute Deluxe’s

vertical vent system does not satisfy the criteria for

Category I venting, it must be vented as a Category III

system.

All Brute Deluxe vent systems which discharge

horizontally (without the use of a power venter) are

considered Category III vent systems.

2.B.2 Category I Vent

When vented as a Category I appliance, the

vent system must conform to the National Fuel Gas

Code (ANSI Z223.1-Latest Edition) in the U.S., or in

Canada, to the Natural Gas and Propane Installation

Code (CSA B149.1 latest edition). The vent system

must be sized and installed for a Category I Fan-

Assisted Appliance.

If chimney height is greater than 25 feet, or

if multiple units are vented into the same vertical

vent, a barometric damper must be installed on each

appliance, such that the ue draft does not exceed

(negative) 0.1 in. w.c.

If using a power venter for any type of Category

I venting, the draft should be set between (negative)

0.01 and 0.05 in. w.c.

2.B.3 Common Venting Systems

Brute Deluxe units are Category I fan-assisted

when vented vertically and adhering to all applicable

codes. Brute Deluxe units are not allowed to be

vented into a common horizontal vent system, unless

a properly sized vent fan is used, and the common

vent system is properly designed by the vent fan

manufacturer or a qualied engineer. When common

venting Brute Deluxe fan-assisted unit with other

appliances through one shared vertical duct called a

“common vent”, special care must be taken by the

installer to ensure safe operation. In the event that

the common vent is blocked, it is possible, especially

for fan-assisted devices, to vent backwards through

non-operating appliances sharing the vent, allowing

combustion products to inltrate occupied spaces.

If the appliances are allowed to operate in this

condition, serious injury or death may occur.

WARNING

Operation of appliances with a blocked common

vent may lead to serious injury or death. Safety

devices must be implemented to prevent blocked

common vent operation. If safe operation of all

appliances connected to a common vent cannot

be assured, including prevention of spillage of

flue gasses into living spaces, common venting

should not be applied, and appliances should

each be vented separately.

The combustion air can be taken through the

wall, or through the roof. When taken from the wall,

it must be taken from out-of-doors by means of the

Bradford White horizontal wall terminal (see Table 1).

When taken from the roof, a eld-supplied rain cap or

an elbow arrangement must be used to prevent entry of

rain water (see Figure 3).

Use single-wall galvanized pipe for the

combustion air intake (see Table 1 for appropriate

size). Route the intake to the heater as directly as

possible. Seal all joints with tape. Provide adequate

hangers. The unit must not support the weight of the

combustion air intake pipe. Maximum linear pipe

length allowed is 50 feet (15.2m). Three elbows have

been calculated into the 50-foot (15.2m) linear run.

Subtract 10 allowable linear feet (3.0m) for every

additional elbow used (see Table 1). When fewer than

3 elbows are used, the maximum linear pipe length

allowed is still 50 feet (15.2m).

Term Description

Pipe Single-wall galvanized steel pipe, 24 gauge

minimum (either insulated or non-insulated)

Joint Sealing Permanent duct tape or aluminum tape

Table 3. Required Combustion Air Piping

Material.

The connection for the intake air pipe is on the

lter box. The Brute Deluxe appliances may have

venting and combustion air ducting attached to the top

or the back. They are shipped with the connections

at the top. For attaching either or both pipes to the

back, the mounting anges are reversible by removing

the mounting screws and orienting the anges in the

desired position. Replace the screws after positioning

anges. Run a bead of silicone around the collar and

slide the pipe over the collar. Secure with sheet metal

screws.

In addition to air needed for combustion, air

shall also be supplied for ventilation, including all air

required for comfort and proper working conditions

for personnel. The Brute Deluxe loses less than 1

percent of its input rating to the room, but other heat

sources may be present.

d’évents individuels séparés.

It is for this reason that, in addition to

following proper vent sizing, construction and safety

requirements from the National Fuel Gas Code,

ANSI Z223.1 or in Canada, from the Natural Gas

and Propane Installation Code (CSA B149.1) as

well as all applicable local codes, it is required that

installers provide some means to prevent operation

with a blocked common vent. It is suggested that a

blocked vent safety system be employed such that if

the switch from one appliance trips due to excessive

stack spill or back pressure indicating a blocked vent

condition, that all appliances attached to the vent be

locked out and prevented from operating. Note that

the Brute Deluxe is equipped with a blocked vent

safety (pressure) switch, as shipped. However, this

safety switch has only been designed and tested to

be eective in installations where the Brute Deluxe

is vented separately and NOT common vented with

other appliances. As an additional precaution, it is

recommended that a Carbon Monoxide (CO) alarm be

installed in all enclosed spaces containing combustion

appliances. If assistance is required in determining

how a blocked vent safety system should be connected

to a Bradford White product, please call Applications

Engineering at the Rochester phone number on the

back cover of this manual.

Refer to the installation and operating

instructions on all appliances to be common vented

for instructions, warnings, restrictions and safety

requirements. If safe operation of all appliances

connected to a common vent cannot be assured,

including prevention of spillage of ue gases into

living spaces, common venting should not be applied,

and appliances should each be vented separately.

2.B.4 Category III Vent

When the Brute Deluxe is vented with horizontal

discharge, it must be installed per this installation

manual and the venting system manufacturer’s

installation instructions. The vent system must be

sealed stainless steel, per Table 4.

Term Description

Pipe Must comply with UL Standard 1738 such

as Type AL29-4C Stainless Steel

(either insulated or non-insulated).

Joint

Sealing

Follow vent manufacturer's instructions.

Table 4. Required Horizontal Venting Material.

Route the vent pipe to the heater as directly as

possible. Seal all joints and provide adequate hangers

as required in the venting system manufacturer’s

installation instructions. Horizontal portions of the

venting system must be supported to prevent sagging

and may not have any low sections that could trap

condensate.

The unit must not support the weight of the vent

pipe. Horizontal runs must slope downwards not less

than ¼ inch per foot (2 cm/m) from the unit to the vent

terminal.

L’appareil ne doit pas supporter le poids de la

gaine d’évent. Les parties horizontales doivent être

installées avec une pente de 2 cm/m (1/4 inch par pied)

descendant de l’appareil vers la sortie de l’évent.

Reference Table 1 for the size of the Category

III vent system. Up to three elbows can be used with

50 linear feet (15.2m) of pipe. Subtract 10 allowable

linear feet (3.0m) for every additional elbow used.

2.C Locating Vent & Combustion Air

Terminals

2.C.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent

terminal must be used, and is listed in the installation

and operation manual. The terminal provides a means

of installing the vent piping through the building wall,

and must be located in accordance with ANSI Z223.1/

NFPA 54 and applicable local codes. In Canada, the

installation must be in accordance with CSA B149.1

and local applicable codes. Consider the following

when installing the terminal:

1. Figure 4 shows the requirements for mechanical

vent terminal clearances for the U.S. and Canada.

2. Locate the vent terminal so that vent gases cannot

be drawn into air conditioning system inlets.

3. Locate the vent terminal so that vent gases cannot

enter the building through doors, windows, gravity

inlets or other openings. Whenever possible,

locations under windows or near doors should be

avoided.

4. Locate the vent terminal so that it cannot be

blocked by snow. The installer may determine that

a vent terminal must be higher than the minimum

shown in codes, depending upon local conditions.

5. Locate the terminal so the vent exhaust does not

settle on building surfaces or other nearby objects.

Vent products may damage such surfaces or

objects.

2.C.2 Side Wall

Combustion Air Terminal

The Bradford White side wall combustion air terminal

(listed in Table 1) must be used when the unit

takes its combustion air through a duct from a side

wall. Consider the following when installing the

terminal:

1. Do not locate the air inlet terminal near a source

of corrosive chemical fumes (e.g., cleaning uid,

chlorinated compounds, etc.)

2. Locate the terminal so that it will not be subject to

damage by accident or vandalism.

3. Locate the combustion air terminal so that it

cannot be blocked by snow. The National Fuel Gas

Code requires that it be at least 12 inches (30 cm)

above grade, but the installer may determine it

should be higher, depending upon local conditions.

4. If the Brute Deluxe is side-wall vented to the same

wall, locate the vent terminal at least 3 feet (0.9m)

horizontally from the combustion air terminal,

and locate the vent terminal at least 1 foot (0.3m)

above the combustion air terminal (see Figure 4).

2.C.3 Vertical Vent Terminal

When the unit is vented through the roof, the

vent must extend at least 3 feet (0.9m) above the point

at which it penetrates the roof. It must extend at least

2 feet (0.6m) higher than any portion of a building

within a horizontal distance of 10 feet (3.0m), and high

enough above the roof line to prevent blockage from

snow. When the combustion air is taken from the roof,

the combustion air must terminate at least 12" (30cm)

below the vent terminal (see Figure 3).

2.C.4 Vertical Combustion Air Terminal

When combustion air is taken from the roof, a

eld-supplied rain cap or an elbow arrangement must

be used to prevent entry of rain water (see Figure 3).

The opening on the end of the terminal must be at least

12" (30cm) above the point at which it penetrates the

roof, and high enough above the roof line to prevent

blockage from snow. When the vent terminates on the

roof, the combustion air must terminate at least 12"

(30cm) below the vent terminal.

2.D Common Vent Test — Boilers

When an existing boiler is removed from a

common venting system, the common venting system

is likely to be too large for proper venting of the

appliances remaining connected to it.

At the time of removal of an existing boiler, the

following steps shall be followed with each appliance

remaining connected to the common venting system

placed in operation, while the other appliances

remaining connected to the common venting system

are not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper

size and horizontal pitch and determine there is

non blockage or restriction, leakage, corrosion

and other deciencies which could cause an

unsafe condition.

3. Insofar as it is practical, close all building doors

and windows and all doors between the space in

which the appliances remaining connected to the

common venting system are located and other

spaces of the building. Turn on clothes dryers

and any appliance not connected to the common

venting system. Turn on any exhaust fans, such

as range hoods and bathroom exhausts, so they

will operate at maximum speed. Do not operate a

summer exhaust fan. Close replace dampers.

4. Place in operation the appliance being

inspected. Follow the lighting instructions.

Adjust thermostat so appliance will operate

continuously.

5. Test for spillage at the draft hood relief opening

after 5 minutes of main burner operation. Use

the ame of a match or candle, or smoke from a

cigarette, cigar or pipe.

6. After it has been determined that each appliance

remaining connected to the common venting

Page 14

Bradford White Corp

system properly vents when tested as outlined

above, return doors, windows, exhaust fans,

replace dampers and any other gas burning

appliance to their previous conditions of use.

7. Any improper operation of the common venting

system should be corrected so that the installation

conforms with the National Fuel Gas Code,

ANSI Z223.1/NFPA 54 and/or CSA B149.1,

Natural Gas and Propane Installation Codes.

When resizing any portion of the common

venting system, the common venting system

should be resized to approach the minimum size

as determined using the appropriate tables in

Appendix F in the National Fuel Gas Code, ANSI

Z223.1/NFPA 54 and/or CSA B149.1, Natural

Gas and Propane Installation Codes.

2.D Véricationdeséventscommuns—

Chaudières

Lorsqu’une chaudière existante est déconnectée

du réseau d’évents commun, ce réseau d’évents

commun devient probablement trop grand pour

les appareils qui lui restent connectés. Lorsqu’une

chaudière existante est retirée, les étapes suivantes

doivent être accomplies pour chaque appareil qui

reste connecté au réseau d’évents commun utilisé,

alors que les autres appareils qui sont encore

connectés au réseau commun d’évents ne sont pas en

fonctionnement.:

1. Sceller toutes les ouvertures non utilisées du

système d'évacuation.

2. Inspecter de façon visuelle le système

d'évacuation pour déterminer la grosseur et

l'inclinaison horizontale qui conviennent et

s'assurer que le système est exempt d'obstruction,

d'étranglement, de fuite, de corrosion et autres

défaillances qui pourraient présenter des risques.

3. Dans la mesure du possible, fermer toutes les

portes et les fenêtres du bâtiment et toutes les

portes entre l'espace où les appareils toujours

raccordés au système d'évacuation sont installés

et les autres espaces du bâtiment. Mettre en

marche les sécheuses, tous les appareils non

raccordés au système d'évacuation common

et tous les ventilateurs d'extraction comme

les hottes de cuisinière et les ventilateurs des

salles de bain. S'assurer que ces ventilateurs

fonctionnent à la vitesse maximale. Ne pas faire

2.E Vent Terminals for Outdoor Units

For outdoor applications, the vent and

combustion air openings must be covered with proper

terminals to prevent rain, snow and other objects from

falling into the Brute Deluxe.

Outdoor Vent / Air kit part numbers are shown in

Table 6. These kits contain parts for both combustion

air inlet and exhaust vent connections. An angled sheet

metal assembly with louvers replaces the sheet metal

assembly with the air collar. An adapter, a 12" length

of pipe, and a rain cap are included for the exhaust

vent opening.

If local codes allow, Bradford White kits are

not required for outdoor units. The installer may use

12" of appropriately sized galvanized single wall or

b-type vent pipe and a rain cap for the exhaust vent. In

addition, an appropriately sized galvanized 90° elbow,

positioned with the opening facing down, may be used

on the combustion air inlet.

Notes:

1. These gures are based on 1/2" (0.12 kPa) water column pressure drop.

2. Check supply pressure and local code requirements before proceeding with work.

3. Pipe ttings must be considered when determining gas pipe sizing.

Table 6. Gas Piping Size.

SECTION 3 Gas Supply and Piping

3.A Gas Supply and Piping

Gas piping should be supported by suitable

hangers or oor stands, not by the appliance.

The Brute Deluxe’s gas train allows the user to

pipe the gas from either the right side or the left side

of the unit. As shipped, the right side of the gas train is

capped o, and there is a manual valve on the left side.

If desired, the manual valve on the left side of the gas

train may be moved to the right side, and the cap on

the right side may be moved to the left.

Review the following instructions before

proceeding with the installation.

1. Verify that the appliance is tted for the proper

type of gas by checking the rating plate. Brute

Deluxe appliances are equipped to operate at

elevations up to 10,000 feet (3050m). Brute

Deluxe appliances may be adjusted to operate

properly at altitudes above 2500 feet (see Section

6.5.2) and the input will be reduced if the heating

value of the gas supply is below sea level values.

2. The maximum inlet gas pressure must not

exceed 13" w.c. (3.2kPa). The minimum inlet gas

pressure is 5 in. w.c. (1.2 kPa).

3. Refer to Table 6, to size supply.

4. Run gas supply line in accordance with all

applicable codes.

5. Locate and install manual shuto valves in

accordance with state and local requirements.

6. A sediment trap must be provided upstream of

the gas controls.

7. All threaded joints should be coated with

piping compound resistant to action of liqueed

petroleum gas.

8. The appliance and its individual shuto valve

must be disconnected from the gas supply piping

during any pressure testing of that system at test

pressures in excess of 0.5 psig (3.45 kpa).

9. The unit must be isolated from the gas supply

system by closing its individual manual shuto

valve during any pressure testing of the gas

supply piping system at test pressures equal to or

less than 0.5 psig (3.45 kpa).

10. The appliance and its gas connection must be

leak tested before placing it in operation.

11. Purge all air from gas lines.

WARNING

Do not use open flame to check for leaks.

An open flame could lead to explosion, which

could result in property damage, serious injury

or death.

AVERTISSEMENT

Ne recherchez pas les fuites avec une flamme

nue. Une flamme nue peut provoquer une

explosion qui peut causer des dommages

matériels, de sérieuses blessures corporelles

ou la mort.

NOTE: The Brute Deluxe appliance and all other

gas appliances sharing the gas supply line must

be firing at maximum capacity to properly measure

the inlet supply pressure. The pressure can be

measured at the supply pressure port on the gas

valve. Low gas pressure could be an indication of

an undersized gas meter, undersized gas supply

lines and/or an obstructed gas supply line.

Page 16

Bradford White Corp

SECTION 4 Water Connections —

4.A Brute Deluxe Boiler

4.A.1 Heating System Piping:

Hot Supply Connections — Boiler

NOTE: This appliance must be installed in a closed

pressure system with a minimum of 12 psig (82.7

kPa) static pressure at the boiler.

Hot water piping should be supported by suitable

hangers or oor stands. Do not support piping with

this appliance. Due to expansion and contraction of

copper pipe, consideration should be given to the type

of hangers used. Rigid hangers may transmit noise

through the system resulting from the piping sliding in

the hangers. It is recommended that padding be used

when rigid hangers are installed. Maintain 1" clearance

to combustibles for hot water pipes.

Pipe the discharge of the relief valve (full size)

to a drain or in a manner to prevent injury in the event

of pressure relief. Install an air purger, an air vent,

a diaphragm-type expansion tank, and a hydronic

ow check in the system supply loop. Minimum ll

pressure must be 12 psig (82.7 kPa). Install shuto

valves where required by code.

Suggested piping diagrams are shown as Figure 5,

Figure 6, Figure 7, and Figure 8, and Figure 9. These

diagrams are meant only as a guide. Components

required by local codes must be properly installed.

4.A.2 Cold Water Make-Up — Boiler

1. Connect the cold water supply to the inlet

connection of an automatic ll valve.

2. Install a suitable back ow preventer between the

automatic ll valve and the cold water supply.

3. Install shut o valves where required.

NOTE: The boiler, when used in connection with a

refrigeration system, must be installed so the chilled

medium is piped in parallel with the boiler with

appropriate valves to prevent the chilled medium

from entering the boiler.

The boiler piping system of a hot water heating

boiler connected to heating coils located in air

handling appliances where they may be exposed to

refrigerated air circulation must be equipped with ow

control valves or other automatic means to prevent

gravity circulation of the boiler water during the

cooling cycle.

A boiler installed above radiation level, or as

required by the authority having jurisdiction, must be

provided with a low water cuto device either as a part

of the boiler or at the time of boiler installation.

4.A.3 Water Flow Requirements — Boiler

A hydronic heating (closed loop) application

recirculates the same uid in the piping system. As a

result, no new minerals or oxygen are introduced into

the system. To ensure a proper operating temperature

leading to long boiler life, a ow rate has been

established based on the uid temperature rise for this

specic size boiler.

Pump-mounted boilers can be ordered for use in

primary secondary piping systems. The pumps used

are sized for the head loss through the heater, plus 30

feet (9.1 m) of full-sized piping (same size as boiler

outlet) and a normal number of ttings.

Table 8 species water ow rates for boilers,

which will enable the user to size a pump. The head

loss shown is for the heater only, and the user will

need to add the head loss of the system piping to

properly size the pump.

The minimum inlet water temperature for the

Brute Deluxe is 120°F (49°C) to avoid condensing on

the copper coils.

4.A.4 Freeze Protection — Boiler

Boiler installations are not recommended in

areas where the danger of freezing exists unless proper

precautions are made for freeze protection. A non

toxic, heating system, anti-freeze may be added to

the hydronic system provided that the concentration

does not exceed 50% and the anti freeze contains an

anti foamant. When a 50/50 mixture is used, increase

the water ow requirements by 15%, and increase the

head loss requirements by 20%.

Power outage, interruption of gas supply, failure

of system components, activation of safety devices,

etc., may prevent a boiler from ring. Any time a

boiler is subjected to freezing conditions, and the

boiler is not able to re, and/or the water is not able

to circulate, there is a risk of freezing in the boiler

or in the pipes in the system. When water freezes,

it expands. This can result in bursting of pipes in the

system, or damage to the boiler, which could result in

leaking or ooding conditions.

IMPORTANT NOTES: Different glycol products

may provide varying degrees of protection. Glycol

products must be maintained properly in a heating

system, or they may become ineffective. Consult

the glycol specifications, or the glycol manufacturer,

for information about specific products,

maintenance of solutions, and set up according to

your particular conditions. Never use ethylene glycol

(automotive antifreeze).

4.B.1 Water System Piping — Water Heater

Hot water piping should be supported by suitable

hangers or oor stands. Do not support piping with

this appliance. Due to expansion and contraction of

copper pipe, consideration should be given to the type

of hangers used. Rigid hangers may transmit noise

through the system resulting from the piping sliding in

the hangers. It is recommended that padding be used

when rigid hangers are installed.

The Brute Deluxe can be used with several

dierent types of readily available storage tanks. A

pump draws water from the storage tank and pumps

the water through the heater and back into the tank.

Pump-mounted units have a circulating pump built

into the water heater. The pumps used are sized for

the head loss through the heater, plus 30 feet (9.1 m)

of full-sized piping (same size as boiler outlet) and

a normal number of ttings. Pumps used on pump-

mounted unit are sized for soft/normal or hard water,

so make sure a pump-mounted unit matches the water

quality of the installation.

Pipe the outlet from the heater’s relief valve

such that any discharge from the relief valve will be

conducted to a suitable place for disposal when relief

occurs. Do not reduce line size or install any valves in

this line. The line must be installed to allow complete

drainage of both the valve and the line.

Suggested piping diagrams are shown as Figure 5,

Figure 6, Figure 7, and Figure 8, and Figure 9. These

diagrams are meant only as a guide. Components

required by local codes must be properly installed.

The minimum inlet water temperature for the

Brute Deluxe is 130°F (54°C) to avoid condensing on

the copper coils.

4.B.2 Hot Water Supply Piping —Water

Heater

Follow the tank manufacturer’s guidelines for

completion of the hot water system connections.

NOTE: A listed temperature and pressure relief

valve listed as complying with the Standard

for Relief Valves and Automatic Gas Shutoff

Devices for Hot Water Supply Systems (ANSI

Z21.22/CSA 4.4), of suitable discharge capacity

must be installed in the separate storage tank

system.

If the Brute Deluxe water heater is installed in

a closed water supply system, such as one having a

backow preventer in the cold water supply line, the

relief valve may discharge periodically, due to thermal

expansion. Means (such as a properly-sized expansion

tank) shall be provided to control thermal expansion.

Contact the water supplier or local plumbing inspector

on how to control this situation.

4.B.3 Water Flow Requirements —

Water Heater

In a water heating application (an open system),

new water is constantly being introduced. With the

new water comes a fresh supply of minerals that can

be deposited on the unit’s heat exchanger. This is

commonly known as scaling. The amount of minerals

will depend upon the hardness of the water. Water can

also be aggressive, and can erode metals, including

copper, if the water is moved too quickly. The water

ow requirements for the Brute Deluxe water heater

are based upon the hardness of the water. The water

ow is kept high enough to prevent scaling, but low

enough to prevent tube erosion. For extremely soft or

hard water, cupro-nickel tubes are available. Contact a

Bradford White representative if you have questions or

concerns about water quality.

Pump-mounted water heaters can be ordered with

standard pumps for soft or normal water. The pumps

used are sized for the head loss through the heater, plus

30 feet (9.1m) of full-sized piping (same size as heater

outlet) and a normal number of ttings. For hard water

conditions (more than 17 grains per gallon), use a

non-pump-mounted heater with a properly-sized eld-

installed pump.

Table 8 species water ow rates for water

heaters, which will enable the user to size a pump. The

head loss shown is for the heater only, and the user

will need to add the head loss of the piping system to

properly size the pump.

4.B.4 Combined Water Heating (potable) and

Space Heating — Water Heater

NOTE: These systems are not allowed in the

Commonwealth of Massachusetts.

Piping and components connected to this water

heater for the space heating application shall be

suitable for use with potable water.

Toxic chemicals, such as used for boiler

treatment, shall not be introduced into the potable

water used for space heating.

This water heater when used to supply potable

water shall not be connected to any heating system

or component(s) previously used with a non-potable

water heating appliance.

When the system requires water for heating at

temperatures higher than required for other uses,

an anti-scald mixing or tempering valve shall be

installed to temper the water for those uses in order

to reduce scald hazard potential.

4.B.5 Freeze Protection — Water Heater

Although Brute Deluxe water heaters are design-

certied for outdoor installations, such installations

are not recommended in areas subject to freezing

temperatures, unless proper precautions are taken.

Power outage, interruption of gas supply, failure

of system components, activation of safety devices,

etc., may prevent a heater from ring. Any time a

heater is subjected to freezing conditions, and the

heater is not able to re, and/or the water is not

able to circulate, there is a risk of freezing in the

heater or in the pipes in the system. When water

freezes, it expands. This can result in bursting of pipes

in the system, or damage to the heater, which could

result in leaking or ooding conditions.

Contact the local factory representative or

Bradford White for additional information.
