SECTION 1:Introduction

Heatstar ERXL models are low-cost, field assembled infrared heaters

that are easy to install and require only minimal maintenance. They are designed to provide years of economical operation and

trouble-free service.

Checking Shipment

Check the shipment against the Bill of Lading for shortages. Also, check for external damage to cartons. Note any shortages, and/ or external damage to cartons on the Bill of Lading in the presence of the delivery trucker. The delivery trucker should acknowledge

any shortages or damage by initializing this “noted” Bill of Lading.

Immediately report any claims for damaged material, or shortages that were not evident at the time of shipment, to the carrier and your Enerco Group, Inc Factory Representative.

Installer Responsibility

All heaters and associated gas piping should be installed in accordance with applicable specifications and this installation made only by firms (or individuals) well qualified in this type of work. Consult local building inspectors, Fire Marshals or your local Enerco Group, Inc Factory Representative for guidance. Heatstar ERXL heaters are installed on the basis of information given in a layout drawing, which together with the cited codes and regulations, comprise the basic information needed to complete the installation. The installer must furnish all needed material that is not furnished as standard equipment, and it is his responsibility to see that such materials, as well as the installation methods he uses result in a job that is workmanlike and in compliance with all applicable codes.

SECTION 2: Planning

The following codes and instructions should be followed when planning the installation of the Heatstar ERXL 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.

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 ERXL 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 distance 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 burners 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 Propane Installation Code, CSA B149.1.

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

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

COUPLING ASSEMBLY

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. (See Figure 4)

Outside Combustion Air Supply

The Ener-Radiant XL 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.

PVC Pipe, “Dryer Hose”, or equivalent may be used instead of

standard vent pipe.

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. The ignition module then energizes the hot surface igniter for a

timed warm-up period (approximately 45 to 60 seconds.)

4. After the warm-up period, the gas valve is energized.

5. During the last part of the sequence, the igniter is de-energized

and is converted to a flame sensing rod.

6. If a flame is detected, the gas valve remains open. When the call for heat is satisfied, and the system control mechanism

de-energizes the burner line voltage supply, the gas valves are

Yellow

Air Switch

E-18

turned off.

7. If no flame is detected on a single-try module, the gas valve

is closed, and the module will lockout until it is reset. Reset is accomplished by removing power from the module for at least five (5) seconds (thermostat cycle required.)

8. If no flame is detected on a three-trial module, the gas valve is

closed, and a purge period begins. After the purge, the module

acts to power the igniter for a second warm-up period, and a

second trial for ignition period. If flame is still not established, a

third and final purge, warm-up, 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.)

9. On a three-trial module, if flame is established and lost on the first or second trial, the gas valve is turned off, a purge, warm-up, and trial for ignition will occur on a three-trial module, only three

trials for ignition are allowed per thermostat cycle.

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. When using compressed air do not exceed 30 psi in order to not damage fragile hot surface igniter.

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.

Troubleshooting

CAUTION: Before opening the Ener-Radiant XL

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 Glow: 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
