The Gas

Supply Line

NOTE: Have the gas supply line installed in accordance with local building codes by a qualified installer ap- proved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter).

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 1/2 inch (13 mm) hook-up at the unit.

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

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

A 1/8 inch (3 mm) N.P.T. plugged tapping, accessible for test gauge connection, should be provided for in the gas supply line leading to the unit’s shut-off valve.

Remove the decorative door on the unit by pulling away from the unit to release it from the clips on each side.

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

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, all connections must be tightened and checked for leaks with a commercially-avail- able, non-corrosive leak check solution. Be sure to rinse off all leak check solution following testing.

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

The gas line should be installed by a qualified service technician.

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