Note: To test the gas pressure, turn off the gas supply before removing
the plug from the supply pressure test port or manifold pressure test
port.
Verify gas pressures with the fireplace lit and on the highest setting.
Please refer to the Burner Installation Manual for gas pressure testing
procedure.
Caution: The gas line should be installed by a qualified service person in accordance with all building codes.
This section is intended as a guide for qualified technicians installing this appliance. Consult local and / or
national building codes before proceeding.
• Gas supply line access holes are located at the top and left sides of the Control Box. Gas valve inlet
accepts a 3/8" N.P.T. fitting. Correct gas line diameter must be used to assure proper operation and
pressure.
• NOTE: A sediment trap, as per national fuel gas code, must be installed in the gas supply line no
more than 6 feet from the gas control valve to minimize the possibility of any loose scale or dirt
within the gas supply line from entering the control valve.
DO NOT HARD PIPE GAS LINE TO VALVE.
A method of disconnecting the valve from the gas line such as
a union or flare fitting must be provided to allow for repair or replacement of the gas valve.
Check local codes for additional requirements.
1. Connect the gas supply to the valve (Figure 22).
2. Turn on the gas supply and check that all connections are tight and leak free.
