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
(30') ft. maximum length or two (2') 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.

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.

Operating Instructions and Owner's Manual
Shut-Off Valve must be parallel
to burner gas inlet. The 2"
displacement shown is for the cold
condition. This displacement may
reduce when the system is fired.
