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.

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 main gas valve located on or near gas meter.

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.

5.Correct all leaks at once.

6.Reconnect heater and manual shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG

1.Close manual shutoff valve (see Fig- ure 14).

2.Pressurize supply piping system by ei- ther using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to manual shutoff valve (see Figure 15). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Heater Gas Connections

1.Open manual shutoff valve (see Fig- ure 14).

2.Open main gas valve located on or near gas meter.

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

4.Check all joints from manual shutoff valve to thermostat gas valve (thermo- stat-controlled models) or control valve (manually-controlled models) (see Fig- ure 15). Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 14 through 16). Check all other internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appliance, page 15 [thermostat- controlled models] or page 16 [manu- ally-controlled models]).
