SECTION 1
SECTION 2
Introduction
Ener-Radiant ERXL models are low-cost, eld 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 Factory Representative.
Installer Responsibility
All heaters and associated gas piping should be installed in
accordance with applicable specications and this installation made
only by rms (or individuals) well qualied 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.
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.
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).
• 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.
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 oor.)
• In other sections of aircraft hangers, such
as shops or ofces, heaters must not be
installed less than 8 feet above the oor.
• 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 oor. Minimum clearances
to combustibles must be maintained from
vehicles parked below the heater.
Operating Instructions and Owner’s ManualEnerco | enerRadiant® XL Series Heater

Page 4
• When installed over hoists, minimum
clearances to combustibles must be maintained from the uppermost point on the
hoist.
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.
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 congurations for venting
arrangements.
• Any portion of ue 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 re insurance
carrier or other authorities for approval of the
proposed installation.
Critical Considerations
Ener-Radiant ERXL is a suspended heater.
Therefore, its stability, exibility, and safety are
very important. Before starting installation,
be sure the system can meet the following
requirements.
• Maintain specied clearances to combustibles, and safe distance from the heatsensitive material, equipment and work
stations.
• 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 sufciently exible to
accommodate thermal expansion which
occurs as the system heats up (see
Figure 5 on page 15).
• 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 ?).
Locate a support near all elbows.
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. Reectors 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 17).
Have slip joints where required between
reectors 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.
• 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.)

Couplings: Tube and tube ttings 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 identied 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)

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-ve (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 conguration.
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 ange; wood screws or bolts and
expansion sleeves may be used to fasten terminal.
FIGURE 16: Non-Pressurized Outside Air Supply Duct
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 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.
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 tting. All pipe ttings 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 ex gas connector as shown. The ex gas connector
accommodates expansion of the heating system and allows for easy
installation and service of the burner.
Outside Air Terminal: Use ACME #104 Enerco Stk. #19030.
PVC Pipe, “Dryer Hose”, or equivalent may be used instead of
standard vent pipe.

Wiring
Heaters are normally controlled by thermostats. Line voltage
thermostats are wired directly (see Figure 18a), the recommended
24V thermostats use a relay (see Figure 18b). Heaters must be
grounded in accordance with the National Electric Code ANSI/NFPA 70 - latest version. Heaters may also be controlled with a manual line
voltage switch or timer switch in place of the thermostat.
FIGURE 18a: Line Voltage Thermostat Wiring
FIGURE 18b: Low Line Voltage Thermostat Wiring
FIGURE 20: Ener-Radiant XL Burner Internal Wiring
• If any of the original wire as supplied with the
appliance must be replaced, it must be replace with
wiring material having a temperature rating of at least
105°C and 600 volts.
• Each burner must be electrically grounded in
accordance with the National Electric Code ANSI/NFPA
- 70 - latest version.

SECTION 7
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 deenergized and is converted to a ame sensing rod.
6. If a ame is detected, the gas valve remains open.
When the call for heat is satised, and the system
control mechanism de-energizes the burner line
voltage supply, the gas valves are turned off.
7. If no ame 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 ve (5) seconds (thermostat
cycle required.)
8. If no ame 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 ame is still not established, a third and
nal 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 ve (5) seconds (thermostat cycle required.)
9. On a three-trial module, if ame is established and
lost on the rst 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.
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 ring tube with a ashlight. 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 ue pipe for soot or dirt. After cleaning as
necessary, re-attach the ue pipe to the heater.
8. Outside surfaces of heater may be cleaned by wiping
with a damp cloth.
9. A qualied 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.
