WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

WARNING: For propane/LP units, make sure exter- nal regulator has been installed between propane/LP supply and heater. See guidelines under Installing Gas Piping to Fireplace Location, pages 11 and 12.

3.Check all joints from gas meter for natural gas or propane/LP supply to equipment shutoff valve for propane/LP gas (see Fig- ures 18 or 19). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Fireplace Gas Connections

1.Open equipment shutoff valve (see Figure 17).

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

3.Place manual ignition switch in the OFF position.

4.Check all joints from equipment shutoff valve to gas valve (see Figure 18 or 19). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light fireplace (see Operating Fireplace, pages 18 through 20). Check all other internal joints for leaks.

7.Turn off fireplace (see To Turn Off Gas to Appliance, pages

19 or 20).	Open

Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage fireplace gas regulator.

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

3.Pressurize supply piping system by either opening propane/LP sup- ply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.

4.Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.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 17).

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