Access the Control Compartment
See Page 54 for instructions on Accessing the Control Compartment.
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
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
3. When the gas lines are tested and leak free, rinse off the leak testing solution.
