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 mixture of liquid soap and water 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 13.

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

1.Close equipment shutoff valve (see Figure 26).

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 27). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

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

1.

Disconnect fireplace and its individual

 

equipment shutoff valve from gas sup-

 

ply piping system. Pressures in excess 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.
