Step 7. The Gas Supply Line

NOTE: Have the gas supply line installed in accordance with local building codes by a qualified installer approved and/or licensed as required by the locality.

NOTE: Before the first firing of the fireplace, the gas supply line should be purged of any trapped air.

NOTE: Consult local building codes to properly size the gas supply line leading to the 1/2 inch (13mm) hook- up at the unit.

This gas fireplace is designed to accept a 1/2 inch (13mm) gas supply line.

To install the gas supply line:

•A listed (and State of Massachusetts approved) 1/2 inch (13mm) tee-handle manual shut-off valve and a listed flex- ible gas connector are connected to the 1/2 inch (13mm) inlet of the control valve. NOTE: If substituting for these components, please consult local codes for compliance.

•Locate the gas line access hole in the outer casing of the fireplace.

•The gap between the supply piping and gas access hole can be plugged with non-combustible insulation to pre- vent cold air infiltration.

•Insert the gas supply line through the gas line hole, and connect it to the shut-off valve.

•When attaching the pipe, support the control so that the lines are not bent or torn.

•After the gas line installation is complete, use a soap solution to carefully check all gas connections for leaks.

!WARNING: DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

•At the gas line access hole, use insulation to re-pack the space around the gas pipe.

•Insert insulation from the outside of the fireplace and pack the insulation tightly to totally seal between the pipe and the outer casing.
