SECTION 2: Planning

The following codes and instructions should be followed when

planning the installation of the Heatstar ERSP heater. In addition

to these instructions, the warnings in (Section 1) must be carefully

adhered to since improper installation may lead to property damage,

injury, or death.

National Standards and Applicable

Codes

Gas Codes:

The type of gas appearing on the nameplate must be the

type of gas used. Installation must comply with local codes

and recommendations of the local gas company, and the

National Fuel Gas Code, ANSI Z223.1 – latest revision,

(same as NFPA Bulletin 54) or the Natural Gas and Propane

Installation Code, CSA B149.1.

• Clearance between the heater and its vent and adjacent

combustible material (which is part of the building or its

contents) shall be maintained to conform with the Standard

for Installation of Gas Appliances and Gas Piping, NFPA-54 /

ANSI Z223.1 – latest revision, National Fuel Gas Code or the

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

Aircraft Hangers:

Installation in aircraft hangers must be in accordance with

the Standard for Aircraft Hangers, ANSI / NFPA-409 – latest

revision.

• Heaters in aircraft storage or service areas shall be installed

at a height of 10 feet above the upper surface of wings

or engine enclosures of the highest aircraft which may be

housed in the hanger. (This should be measured from the

bottom of the heater to the wing or engine enclosure,

whichever is highest from the floor.)

• In other sections of aircraft hangers, such as shops or offices,

heaters must not be installed less than 8 feet above the

floor.

• Heaters installed in aircraft hangers shall be located so as

not to be subject to damage by aircraft, cranes, moveable

scaffolding or other objects.

Public Garages:

Installations in garages must be made in accordance with the

Standard for Parking Structures, NFPA-88A – latest revision

or the Standard for Repair Garages, NFPA-88B – latest

revision.

• Heaters must not be installed less than 8 feet above

the floor. Minimum clearances to combustibles must be

maintained from vehicles parked below the heater.

• When installed over hoists, minimum clearances to

combustibles must be maintained from the uppermost point

on the hoist.

Venting:

The venting must be installed in accordance with NFPA-54 /

ANSI Z223.1 or CSA 149.1– latest revision, National Fuel Gas

Code. Partial information with regard to this code is provided

in (Section 5) of this installation manual with regard to size

and configurations for venting arrangements.

• Any portion of flue pipe passing through a combustible wall

must be dual insulated or have an approved thimble. Refer to

ANSI-Z223.1 or CSA149.1– latest revision.

Hazardous Locations:

Where there is the possibility of exposure to combustible

airborne material or vapor, consult the local Fire Marshal, the

fire insurance carrier or other authorities for approval of the

proposed installation.

Critical Considerations

Heatstar ERSP is a suspended heater. Therefore, its stability,

flexibility, and safety are very important. Before starting

installation, be sure the system can meet the following

requirements.

• For either indoor or outdoor installation. Not for use in resi-

dential dwellings.

• Maintain specified clearances to combustibles, and safe dis-

tance from the heat-sensitive material, equipment and work

stations.

• The stated clearances to combustibles represent a surface

temperature of 90°F (30°C) above room temperature.

Building materials with low heat tolerance (such as plastic,

vinyl siding, canvas, etc.) may be subject to degradation at

lower temperatures. It is the installers responsibility to assure

that adjacent materials are protected from degradation.

• Provide a suspension with vertical length of chain or swinging

rod which has at least 2 inches of horizontal travel for each

burner in a straight run. Be sure the suspension system is

sufficiently flexible to accommodate thermal expansion which

occurs as the system heats up (see Figure 6 on page 12).

• Provide access to burners for servicing, preferable on both

sides, above and behind the burner for removal.

• Provide a minimum of 18 inches of clearance between burn-

ers and building walls. (Always observe minimum clearances

to combustibles.)

• Be sure the heater has a downward pitch of one-half inch per

20 feet away from the burner. (1.25 cm per 6.1 m)

• Provide signs in storage areas to specify maximum stacking

height to maintain required clearances to combustibles.

• Plan location supports (see Figure 2A-G starting on page 8).

Locate a support near all elbows.

• The installation must conform with local building codes or

in the absence of local codes, with the National Fuel Gas

Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Pro-

pane Installation Code, CSA B149.1.

• If an external electrical source is utilized, the heater, when

installed, must be electrically grounded in accordance with

the National Electrical Code, ANSI/ NFPA 70 or current

Canadian Electrical Code, CSA C22.1.

Installation Procedure

NOTE: For either indoor or outdoor installation. Not for use in residential dwellings.

Take maximum advantage of the building upper structure, beams, joists, purlins, etc., from which to suspend the heater. There is no

unique sequence for installation of the tubing. On-site observation will usually reveal a logical sequence. Begin the installation at the most

critical dimension. This could save time. Watch for swinging doors, overhead cranes, car lifts etc. Reflectors and tubing can be installed as

you move along. Carefully adjust system pitch at each position to level the heater. Pitch down one-half inch in 20 feet (away from burner).

DON’T Pressure test the gas line using high pressure (greater than ½ PSIG) without closing the high-pressure shutoff cocks. Failure to do so will

result in damage to the burners.

DO Familiarize yourself with local and national

codes.

Develop a planned procedure which will conserve material and labor on the job.

Check to see that all material and equipment is on the job before starting installation.

Allow for thermal expansion of the hot tube.

Install the gas connector only as shown in instructions (see Figure 14 on page 17).

Have slip joints where required between reflectors to keep them from buckling or coming apart.

Provide 1 sq. inch of free air opening to each 1,000 BTU/hr. of heater input (but not less than 100 sq. inches) in enclosed spaces. One

opening should be within 12 inches of the top and one within 12 inches of the bottom of the enclosure.

Burner Housing

Must always be

installed horizontally.

Tube and Reflector Hanger

Install immediately after first

coupling.

Turbulator Assembly

Enerco Group, Inc normally ships Ener-Radiant heaters with

turbulators assembled into appropriate tubes.

Tube and Reflector Hanger

Suspend system from these hangers.

Minimum two (2) required per tube.

Reflectors

Alternate overlap as shown

on overview. Length of

reflector and amount of

overlap is indicated.

10' 2-1/2" ALUMINIZED

Heat Exchange Tubes

Supplied in 10 ft. lengths.

Tube Coupling Assembly

Coupling should be oriented with

slide bar on top, and all couplings

should “point” in the same direction.

Assemble the heater components as shown in Figures 2A, 2B, 2C, 2D, 2E, 2F and 2G. Optional reflector configurations are shown in Figure

1. Install appropriated suspension hardware, beam clamps, chain or rod at predetermined locations. Adjustment of chain length will provide

uniform pitch.

Couplings: Tube and tube fittings are connected by wrap-around

couplings which clamp by means of a tapered,

hammer-driven lock member. The starting ends of

the coupling and lock member are identified by 1/4”

holes which are put together when starting assembly.

Be sure the tube ends are in line and tube ends butt

against stop pin(s) inside coupling. The slide bar is to

be hammer-driven to a point of securing the coupling

snugly to the tubes. Over-driving will result in distortion

of the coupling or slide bar lip to a point decreasing

the holding the capability of the coupling.

E-17 Operating Instructions and Owner’s ManualEnerco | Heatstar ERSP Series Heater

Outside Combustion Air Supply

The Ener-Radiant SP heater is approved for installation with an

outside air supply system. Some compounds such as halogenated

hydrocarbons or other corrosive chemicals in the air can be drawn

into the equipment and cause an accelerated rate of corrosion

of some of the heater components. The use of such chemical

compounds near the enclosure should be avoided.

IMPORTANT: If the building has a slight negative pressure or

contaminants are present in the air, an outside combustion air

supply to the heaters is strongly recommended.

For an outside air supply, a four (4”) inch (10 cm) O.D. single

wall pipe may be attached to the heater. The duct may be up to

thirty (30’) ft (9.15 m). maximum length or two (2’) ft. minimum

(0.61m) length with no more than two (2) elbows. (See General

Requirements on page 14 for additional information.)

The air supply duct may have to be insulated to prevent

condensation on the outer surface. The outside air terminal should

be securely fastened to the outside wall by drilling four (4) 1/4”

(0.635 cm) diameter holes in the outside flange; wood screws or

bolts and expansion sleeves may be used to fasten terminal.

SECTION 6

Gas Piping

Read applicable warnings in (Section 1) before proceeding with

Gas Pipe installation. Improper installation may result in property

damage, severe injury, or death.

Meter and service must be large enough to handle all the burners

being installed plus any other connected load. The gas line which

feed the system must be large enough to supply the required gas

with a maximum pressure drop of 1/2” water column (0.12 kPa).

When gas piping is not included in the layout drawing, the local gas

supplier will usually help in planning the gas piping.

A 1/2” tapping at each burner location must be located and

oriented as shown in (Figure 14). To check system pressure, put a

plugged 1/8” NPT tapping in the gas line at the connection to the

burner farthest from the supply. Before connecting the burners to

the supply system, verify that all high pressure testing of the gas

piping has been completed. Do not high pressure test the gas piping

with the burners connected.

Follow these instructions to ensure a professional gas supply

installation:

• Support all gas piping with suitable pipe hanging

materials.

• Use wrought iron or wrought steel pipe and malleable

iron fitting. All pipe fittings should be new and free

from defects. Carefully ream the pipe and tubing ends

to remove obstructions and burrs.

• Use L.P. gas-resistant joint compound on all pipe

threads.

• Check the pipe and tubing ends for leaks before

placing heating equipment into service. When

checking for gas leaks, use soap and water solution:

NEVER USE AN OPEN FLAME.

Install the flex gas connector as shown. The flex gas connector

accommodates expansion of the heating system and allows for easy

installation and service of the burner.

Operation & Maintenance

Sequence of Operation

1. Turn the thermostat up. When the thermostat calls for heat,

blower motor will energize.

2. When the motor approaches nominal running RPM, the air

proving switch closes and activates the ignition module.

3. Once the igniter sparks, the gas valve is energized.

4. If a flame is detected, the gas valve remains open. When the call

for heat is satisfied the system control mechanism de-energizes

the burner line voltage supply and the gas valve is turned off.

5. If no flame is detected, the gas valve is closed, and a purge

period begins. After the purge, the module acts to power

the igniter for a second trial for ignition period. If flame is still

not established, a third and final purge and trial cycle begins.

After three trials, the module will lockout until reset. Reset is

accomplished by removing power from the module for at least

five (5) seconds (thermostat cycle required.)

CAUTION: Before opening the Ener-Radiant SP

burner door for any type of service, be sure

the gas supply has been shut off at the heater

and the electrical cord from the burner box

has been unplugged.

Blower Motor 1. Is the thermostat calling for heat? Is there

Fails to Run: 115V at the burner receptacle?

2. Check blower side door for seal. Check

door switch. Replace if necessary.

3. Check blower for obstructions. Replace

blower if necessary.

Igniter 1. Check igniter for damage. Replace if

Does Not Spark: necessary.

2. Check voltage and resistance at igniter.

(Voltage should be 115V. Resistance should

be 40-75 ohms.)

3. Check for obstructions to the air inlet and

outlet.

4. Check wiring and hose connections to the

air switch. Replace if necessary.

5. Check voltages at transformer primary and

secondary. Replace transformer or module

if necessary.

Valve Does Not Gas pressure downstream of gas control can

Come On: be measure by using a manometer and

connecting to pressure tap on control/.

1. Check to see if manual valve heater is ON.

2. Check to see if manual valve knob on

heater gas control in ON.

3. Supply gas pressure can be checked at 1/8”

NPT pressure tapping on heater external

manual valve.

4. Check to see if gas control is opening: no

manifold pressure indicates valve is closed.

If the valve is closed, either the gas valve or

the ignition module is faulty.

WARNING: Do not disconnect ground leads

inside heater. Do not interchange grounded

and ungrounded leads on transformer or

ignition module.

Burner Does Not 1. Check to see if gas lines were properly

Light: purged of air.

2. Check inlet and outlet gas pressure during

ignition period.

• Natural inlet pressure should be 4.5” (1.12 kPa)

• Natural outlet pressure at manifold should be 3.5” (0.87 kPa)

• LP inlet pressure should be 11.0” (2.74 kPa)

• LP outlet pressure at manifold should be 10.5” (2.61 kPa)

3. Check for proper orifice and air plate.

HIGH ALTITUDE

Heaters may be fired at full input up to 2000 ft. (610m) above sea

level. Above 2000 ft. (610m) a high altitude conversion kit may be

required to ensure proper burner performance, please consult the

manufacturer. Be prepared to answer factory questions regarding:

type of fuel for the proposed appliance conversion, gas pressure

available at site, and specific altitude at site. The conversion shall

be carried out by a manufacturer’s authorized representative, in

accordance with the requirements of the manufacturer, provincial,

or territorial authorities having jurisdiction and in accordance with

the requirements of the CSA B149.1 or CSA149.2 installation codes.

Maintenance

For best performance, the following maintenance procedures should

be performed before each heating season:

1. Be sure gas and electrical supply to heater are off before

performing any service or maintenance.

2. Check condition of blower scroll and motor. Dirt and dust

may be blown out with compressed air, or a vacuum cleaner

may be used.

3. Check condition of burner. Carefully remove any dust or

debris from inside the burner box or burner cup.

4. Inspect the igniter. Replace igniter if there is excessive carbon

residue, erosion, breakage or other defects.

5. Check the inside of the firing tube with a flashlight. If carbon

or scale are present, scrape out the deposits with a wire

brush or rod, or metal plate attached to a wooden pole.

6. Check to see that the burner observation window is clean

and free of cracks or holes. Clean or replace as necessary.

7. Check the flue pipe for soot or dirt. After cleaning as

necessary, re-attach the flue pipe to the heater.

8. Outside surfaces of heater may be cleaned by wiping with a

damp cloth.

9. A qualified service agency should be contacted for service

other than routine maintenance.

10. Check vent terminal and fresh air inlet to see that they have

not been blocked during the non-heating season. If either

pipe is restricted, the air switch won’t close, resulting in a

no-heat situation.

IGNITION MODULE DIAGNOSTIC INDICATOR FLASHES:

The LED will flash on for 1/4 second, then off for 1/4 second during

a fault condition. The pause between fault codes is 3 seconds.

STEADY ON - Control Fault

(1) FLASHES - Air Flow Fault

(2) FLASHES - Flame Sensed with No Call For Heat

(3) FLASHES - Ignition Lockout

STEADY ON:

Internal control failure.

AIR FLOW FAULT:

Combustion air flow is continually monitored during an ignition

sequence by the air flow switch (PSW). If during the initial call for

heat the pressure switch contacts are in the closed position for 30

seconds without an output to the combustion blower, an air flow

fault will be declared and the control will remain in this mode with

the combustion blower off.

FLAME FAULT:

If at any time the main valve fails to close completely and maintains

a flame, the full time flame sense circuit will detect it and energize

the combustion blower. Should the main valve later close completely

removing the flame signal, the combustion blower will power off

following the optional post purge period.

IGNITION LOCKOUT:

Should the main burner fail to light, or flame is not detected during

the trial for ignition period, the contol will go into lockout. The valve

will be turned off immediately, and the combustion blower will be

turned off following the optional post purge period.
