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.

• 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.)

WARNING:
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY OR
DEATH.
In all situations, clearances to combustibles must be maintained.
Failure to observe clearances to combustibles may result in
property damage, severe injury, or death.
Minimum clearances must be maintained from vehicles parked
below the heater. Signs should be posted in storage areas to
specify maximum stacking height to maintain required clearances
to combustibles.
Caution should be used when running the system near
combustible materials such as wood, paper, rubber, etc.
Consideration should be given to partitions, storage racks, hoists,
building construction, etc.
TABLE 1 gives minimum acceptable clearances to combustibles.
Clearances as shown in TABLE 1 are not for use in four-sided
enclosures.
