Step 7. 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 the 1/2 inch (13mm) 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.

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

•The gas line may be run from either side of the fireplace provided the hole in the outer wrap does not exceed 2 1/2” in diameter and it does not penetrate the actual firebox.

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

•Open the fireplace lower grille, 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 com- mercially-available, non-corrosive leak check 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.

Use a wrench on shut-off valve when tightening gas line.

Step 8. Gas Pressure Requirements

Pressure requirements for these gas fireplaces are shown in the table below.

Pressure	Natural Gas	Propane
Minimum	5.0 inches	11.0 inches
Inlet Pressure	w.c.	w.c.
Maximum Inlet	14.0 inches	14.0 inches
Gas Pressure	w.c.	w.c.
Manifold	3.5 inches	10.0 inches
Pressure	w.c.	w.c.

A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is provided on the inlet and outlet side of the gas control for a test gauge connection to measure the manifold pressure. Use a small flat blade screwdriver to crack open the screw in the center of the tap. Position a rubber hose over the tap to obtain the pressure reading.

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).
