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 35 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
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 70).
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 gas control knob (OFF/PILOT/ON) to the OFF position (millivolt units), or turn the
receiver or remote control to the OFF position (electronic units). 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

1. With the gas line installed, inspect the system before closing the front of the unit.
2. Follow the pilot lighting instructions:
• Millvolt Systems (Page 70)
• Electronic Systems (Page 72 traditional, Page 74 contemporary)
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. Inspect the pilot flame (carefully remove logs, if necessary).
Millivolt Fireplace Inspection
The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the
outer edge. The top 3/8" (10 mm) at the pilot generator (thermopile) and the top 1/8" (3.175 mm) minimum (tip) of
the quick drop out thermocouple should be engulfed in the pilot flame. The flame should project 1" (25 mm) beyond
the hood at all three ports (Figure 36). Replace the logs if removed for pilot inspection.
To light the burner, turn ON the remote wall switch and rotate the gas valve control knob counterclockwise to the ON
position (the top of the valve).
Electronic Fireplace Inspection
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 (Figure 37).
