2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fire- place, or using compressed air.

4.Check all joints of gas supply piping system. Apply noncorro- sive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

5.Reconnect fireplace and equipment shutoff valve to gas sup- ply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 33).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fire- place, or using compressed air.

3.Check all joints from propane/LP supply tank or gas meter to equipment shutoff valve (see Figure 34, for propane/LP or Figure 35, for natural gas). Apply noncorrosive leak detec- tion fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

1.Open equipment shutoff valve (see Figure 33).

2.Open propane/LP supply tank valve for propane/LP fireplace or main gas valve located on or near gas meter for natural gas fireplace.

3.Make sure control knob of fireplace is in the OFF position.

4.Check all joints from equipment shutoff valve to gas valve (see Figure 34 for propane/LP or Figure 35 for natural gas). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

5.Light fireplace (see Operating Fireplace, pages 23 through 26). Check all other internal joints for leaks.

6.Turn off fireplace (see To Turn Off Gas to Appliance, page 24).

INSTALLING OPTIONAL WALL MOUNT SWITCH - GWMS2

1.Connect one terminal of 25 ft. wire for the wall switch to the TPTH terminal on the valve. Connect remaining wire terminal to the TH terminal on the valve. Make sure that the wire termi- nals are in the positions on the unit as pictured in Figure 36. If wires are not connected as shown the switch will not work.

2.Route the 25 ft. wire through openings provided on the sides of the burner system to a convenient location to mount your switch.

3.Connect one bare wire end to each of the terminals of the GWMS2 wall switch.

4.Install the wall switch and cover in the wall.
