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 14.

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

1.Close equipment shutoff valve (see Fig- ure 27).

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 28). Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

1.Open equipment shutoff valve (see Fig- ure 27).

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 28). Apply a noncorrosive leak de- tection fluid to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light fireplace (see Operating Fire- place, pages 17 and 18). Check all other internal joints for leaks.

7.Turn off fireplace (see To Turn Off Gas to Appliance, page 18).

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 appliance

 

main gas valve (control valve) and

 

equipment shutoff valve from gas sup-

 

ply piping. Pressures in excess of 1/2 psig

 

will damage fireplace regulator.

2.

Cap off open end of gas pipe where

 

equipment shutoff valve was con-

 

nected.

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

6.

Reconnect heater and equipment
