SECTION 2: Planning

The following codes and instructions should be followed when

planning the installation of the Ener-Radiant 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 Stan-

dard 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 com-

bustibles 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 thim-

ble. 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

Ener-Radiant 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.

• 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.

• Provide signs in storage areas to specify maximum

stacking height to maintain required clearances to

combustibles.

• Plan location supports (see Figure 2A-F 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 installed, must be electrically grounded in

accordance with the National Electical Code, ANSI/

NFPA 70 or current Canadian Electrical Code, CSA

C22.1.

Installation Procedure

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.

Burner Housing

Must always be

installed horizontally.

Tube and Reflector Hanger

Install immediately after first

coupling.

Turbulator Assembly

Enerco 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.

Where Field Changes Occur

Turbulator Sections and Adapter are available in

sections and must be assembled before installation

(See Figure 3 for details). The number of sections

required is indicated.

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.

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.

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 O.D. single wall pipe

may be attached to the heater. The duct may be up to forty-five

(30Ê) ft. maximum length or two (2Ê) ft. minimum length with

no more than two (2) elbows. (See General Requirements on

page 15 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‰ diameter holes in the outside flange; wood screws or

bolts and expansion sleeves may be used to fasten terminal.

FIGURE 13: Non-Pressurized Outside Air Supply Duct

PVC Pipe, „Dryer Hose‰, or equivalent may be used instead of

standard vent pipe.

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. 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.

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 wonÊt 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

ignition period.

Natural inlet pressure should be 4.6‰

Natural outlet pressure should be 3.5‰

LP inlet pressure should be 11.0‰

LP outlet pressure should be 10.25‰

3. Check for proper orifice and air plate.

SECTION 8

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

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.

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.
