CHECKING GAS CONNECTIONS
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
pipe. 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 either 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 forming show a leak.
5. Correct all leaks at once.
Test Pressures Equal To or Less Than 1/2 PSIG
1. Close manual shutoff valve (see Figure 8).
2. Pressurize supply piping system by either using compressed air or opening
main gas valve located on or near gas meter.
3. Check all joints from propane supply tank to manual shutoff valve. Apply
mixture of liquid soap and water 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 Figure 8).
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 control valve on heater. Apply
mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Operating Heater, pages 20 through 22). Check the rest of the
internal joints for leaks.
7. Turn off heater (see To Turn Off Gas to Appliance, page 22).
