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

Gas Pressure

Requirements

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 be- tween the pipe and the outer casing.

A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is provided on the outlet side of the gas control for a test gauge connection to measure the manifold pressure. To measure inlet pressure, provisions must be made to attach a test gauge to a one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping immediately upstream of the gas supply connection to the fireplace.

The fireplace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of one-half (1/2) psig (3.5 kPa).

The fireplace must be isolated from the gas supply piping system by closing its individual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than one- half (1/2) psig (3.5 kPa).
