CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections 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.

CAUTION: Make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, page 12.

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 sys-

 

tem. Pressures in excess of 1/2 psig will damage heater regulator.

2.

Cap off open end of gas pipe where equipment shutoff valve

 

was connected.

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 heater and equipment shutoff valve to gas supply.

 

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 18, page 14).
