NOTE:
Seal around the gas line to prevent cold air leakage. Gas line holes and other openings can be caulked or
stuffed with unfaced fiberglass insulation.
1.
Unscrew the shutoff valve from the gas flex-line. Apply thread sealant appropriate for the gas type, and then
connect the shutoff valve to the gas stub.
NOTE:
Position the shutoff valve to allow easy operation through the access opening in the fireplace floor.
2.
Connect the flare fitting on the flex-line to the shutoff valve. Tighten by hand, and then use a pipe wrench to
tighten completely, 1/4-turn at a time.

The control valve has a 3/8” (10 mm) NPT thread inlet port. Secure all joints tightly using appropriate tools and sealing
compounds (ensure propane resistant compounds are used in propane applications). Optionally, seal around the gas line
to prevent cold air leakage. Gas line holes and other openings can be caulked or stuffed with unfaced fiberglass insulation.
All codes require a shutoff valve mounted in the supply line. The orientation of the shutoff valve should face the
front.
Figure 31
illustrates two methods for connecting the gas supply. A sediment trap is recommended to prevent
moisture and debris in the gas line from damaging the valve.
Test Factory and Field Connections for Gas Leaks
WARNING
Never use an open flame to check for leaks.
Turn on gas supply and test for gas leaks, using a gas leak test solution—also known as bubble leak solution.
NOTE:
Using a soapy water solution is an effective leak test solution but it is not recommended, because the soap
residue that is left on the pipes/fittings can result in corrosion over time.
1.
Light the fireplace (refer to the lighting instructions label in the control compartment or
Page 65
)
.
2.
Brush all joints and connections with the gas leak test solution to check for leaks. If bubbles are formed, or gas
odor is detected, turn the receiver or remote control to the OFF position. Either tighten or refasten the leaking
connection, and then retest as described above.
3.
When the gas lines are tested and leak free, rinse off the leak testing solution.
10.
Verify Proper Fireplace Operation
1.
With the gas line installed, inspect the system before closing the front of the unit.
2.
Follow the pilot lighting instructions
(
Page 65
)
.
NOTE:
When lighting the fireplace for the first time, it will take a few minutes for the gas line to purge itself of air. When
purged, the pilot and burner will light and operate as indicated. Subsequent lighting of the fireplace will not require purging.
3.
To light the burner, turn ON the wall or remote control switch. Ensure the igniter lights the pilot. The pilot flame
should engulf the flame rod
