must be done to accomodate natural gas.
Do not connect the venting to the flue of a
chimney that serves a separate solid-fuel
burning appliance.

Gas Line
Making The Connection
The gas inlet is located on the bottom right side
of the fireplace. The inlet fitting is 1/2" male flare fitting
designed for 1/2" stainless flex pipe. This fitting can be
removed to provide 3/8" female pipe thread.
A separate gas shut-off valve and a 1/8" N.P.T.
plugged tapping should be installed immediately up-
stream of the connection to the appliance.
The ShadowLight XL Direct Vent Gas Heater must
be disconnected from the gas supply piping during any
pressure testing of that system at pressures in excess
of 1/2 psig (3.5 kPa).
The ShadowLight XL gas control valve must be
in the OFF position during any pressure testing of the
gas supply system at pressures equal to or less than
1/2 psig (3.5 kPa).
WARNING: To avoid pipe compounds from enter-
ing into the gas train, apply compounds only to male
pipe threads and do not apply compound to the first
two threads.
CAUTION: TEST ALL JOINTS FOR LEAKS BE-
FORE OPERATING.
Gas Pressure Requirements:
Correct gas pressure and the use of a properly
sized gas supply line are essential for the safe and ef-

the plumber or gas supplier checks the gas supply line
and gas pressure at installation.
NOTE: Improper gas pressure can affect heater
performance, flame color, or cause pilot outage.
