FIREPLACE INSTALLATION

To accommodate the various configurations, we have provided access openings in the bottom of the unit for gas line and wall switch wires. This may not be convenient for some installations, if so you may drill an access opening into the lower face of the unit (1" for gas line, 1/2" for the grommet).

1.Route the 3/8 inch N.P.T. black iron gas line or equivalent to the fireplace. Include a manual shut-off valve and union in the line so the control may be disconnected for servicing. A drip leg is also recommended in the gas supply line.

2.Install a rigid black pipe or if local codes permit a 3/8 inch flex connector and shutoff valve to the gas line and the fireplace gas valve. Seal and tighten securely. An adapter fitting is required between the gas valve and flex connector if used. Do not kink flex connector (Figure 3).

3.Check for gas leaks with a soap and water solution. DO NOT USE AN OPEN FLAME.

NOTE: PURGE ALL GAS LINES WITH THE GLASS DOOR OF THE FIREPLACE REMOVED. ASSURE THAT A CONTINUOUS GAS FLOW IS AT THE BURNER BEFORE INSTALLING THE DOOR.
