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 exter- nal regulator has been installed between propane/LP supply and heater. See guidelines under Con- necting to Gas Supply, page 12.

Test Pressures Equal To or Less Than 1/2 PSIG

1.Close manual shutoff valve (see Fig- ure 15).

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 manual shutoff valve (see Figure 16). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

1.Open manual shutoff valve (see Fig- ure 15).

2.Open propane/LP supply tank valve.

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

4.Check all joints from manual shutoff valve to control valve (see Figure 16). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 15 and 16). Check all other in- ternal joints for leaks.

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

Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG

1.

Disconnect heater and its individual

 

manual shutoff valve from gas supply

 

piping system. Pressures in excess of

 

1/2 psig will damage heater regulator.

2.

Cap off open end of gas pipe where

 

manual 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 mixture of liquid soap

 

and water to gas joints. Bubbles form-

 

ing show a leak.
