Operating Instructions and Owner’s Manual
SECTION 1
SECTION 2
Introduction Planning
Ener-Radiant 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.
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.
Checking Shipment
National Standards and Applicable
Codes
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 Factory Representative.
Installer Responsibility
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).
• 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.
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
Factory Representative for guidance.
Ener-Radiant 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.
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.)
ENERCO Factory Representatives have had training and experience
in the application of this equipment and can be called on for
suggestions about installation which can save material and money.
• 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.
Enerco | enerRadiant® XL Series Heater

Operating Instructions and Owner’s Manual
• When installed over hoists, minimum
clearances to combustibles must be maintained from the uppermost point on the
hoist.
• 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.
Electrical: The heater must be electrically grounded in
accordance with the National Electrical Code,
ANSI / NFPA-70 – latest revision. Wiring must
conform to the most current National Electrical
Code, local ordinances, and any special
diagrams furnished.
• Plan location supports (see Figure ?).
Locate a support near all elbows.
Installation Procedure
Venting: The venting must be installed in accordance
with NFPA-54 / ANSI Z223.1 – 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.
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).
• Any portion of flue pipe passing through
a combustible wall must be dual insulated
or have an approved thimble. Refer to
ANSI-Z223.1 – 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.
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.
• Maintain specified clearances to combustibles, and safe distance from the heatsensitive material, equipment and work
stations.
Install the gas connector only as shown in
instructions (see Figure 17).
Have slip joints where required between
reflectors to keep them from buckling or
coming apart.
• 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 5 on page 15).
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.
• 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.)

3) Attach the wire to the hole in the tab on the
adapter piece.
Assemble the heater components as shown
in Figures 2a, 2b, 2c, 2d, 2e, and 2f. 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.
4) Using the wire, pull the assembled turbulator into
the tube from the opposite side.
5) Pull the turbulator through until just the tab comes
out. Detach the wire.
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.
Coupling should be tight when the slide bar is
+- 2” from the end of the coupling.
(See Figure 3)
6) Bend the tab around the tubing. When installing
the tube, the tab will be locked in place by the
adapter.

Operating Instructions and Owner’s Manual
Section 6
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.
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.
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.
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.
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 (45’) ft.
maximum length or two (2’) ft. minimum length with no more than
two (2) elbows. (See General Requirements in page 21 for additional
information.) An outside air supply should not be used with the draft
hood venting configuration.
A 1/2” tapping at each burner location must be located and oriented
as shown in (Figure 17). 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.
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.
Follow these instructions to ensure a professional gas supply
installation:
FIGURE 16: Non-Pressurized Outside Air Supply Duct
•
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 AND 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.

7. Check the flue pipe for soot or dirt. After cleaning as
necessary, re-attach the flue pipe to the heater.
Operation & Maintenance
8. Outside surfaces of heater may be cleaned by wiping
with a damp cloth.
Sequence of Operation
9. A qualified service agency should be contacted for
service other than routine maintenance.
1. Turn the thermostat up. When the thermostat calls for
heat, blower motor will energize.
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.
2. When the motor approaches nominal running RPM,
the air proving switch closes and activates the ignition
module.
Troubleshooting
3. The ignition module then energizes the hot surface
igniter for a timed warm-up period (approximately 45
to 60 seconds.)
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?
4. After the warm-up period, the gas valve is energized.
5. During the last part of the sequence, the igniter is deenergized 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.
2. Check blower side door for seal. Check door
switch. Replace if necessary/
3. Check blower for obstructions. Replace
blower if necessary.
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.)
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.)
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.)
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.
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.
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.
Maintenance
2. Check to see if manual valve knob on heater
gas control in ON.
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.
3. Supply gas pressure can be checked at
1/8” NPT pressure tapping on heater external
manual valve.
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.
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.
3. Check condition of burner. Carefully remove any dust
or debris from inside the burner box or burner cup.
WARNING: Do not disconnect ground leads
inside heater. Do not interchange grounded
and ungrounded leads on transformer or
ignition module.
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.
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.
6. Check to see that the burner observation window is
clean and free of cracks or holes. Clean or replace as
necessary.
