CHECKING GAS

CONNECTIONS

WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect 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.

CAUTION: Make sure external regulator has been installed be- tween propane/LP supply and fire- place. See guidelines under Con- necting to Gas Supply, page 12.

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

1.Close equipment shutoff valve (see Figure 24).

2.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.

3.Check all joints from propane/LP sup- ply tank to equipment shutoff valve (see Figure 25). Apply noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Fireplace Gas Connections

1.Open equipment shutoff valve (see Figure 24).

2.Open propane/LP supply tank valve.

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

4.Check all joints from equipment shutoff valve to thermostat gas valve (see Fig- ure 23, page 13). Apply noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light fireplace (see Operating Fire- place, pages 15 and 16). Check all other internal joints for leaks.

7.Turn off fireplace (see To Turn Off Gas to Appliance, page 16).

8.Replace front panel.

Pressure Testing Gas Supply Piping System

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

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

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

3.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.

4.Check all joints of gas supply piping system. Apply noncorrosive leak detec- tion fluid to gas joints. Bubbles form- ing show a leak.

5.Correct all leaks at once.

6.Reconnect heater and equipment shutoff valve to gas supply. Check re- connected fittings for leaks.
