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 connector (Figure 24).
2.
Turn on the gas supply and check that all connections are tight and leak free.
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.
