Pressure Testing Gas Supply Piping System
Test Pressure in Excess Of 1/2 PSIQ (3.5 K Pa)
1
. Disconnect appliance with its appliance main gas
valve (control valve) and equipment shutoff valve
from gas supply piping system. Pressure in excess of
1/2 psig will damage heater regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either using
compressed air or opening main gas valve located
on or near gas tank.
4. Check all joints of gas supply piping system. Apply
a mixture of liquid soap and water to gas joints.
Bubbles forming indicate a leak.
5. Correct all leaks immediately.
6. Reconnect heater and equipment shutoff valve to gas
supply. Check reconnected ttings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIQ
1
. Close equipment shutoff valve (see Figure 17).
2. Pressurize supply piping system by either using
com pressed air or opening main gas valve located
on or near gas supply tank.
3.
Check all joints from gas tank to equipment shutoff
valve (see Figure 18). Apply mixture of liquid soap
and water to gas joints. Bubbles forming show a leak.
4. Correct all leaks immediately.
Pressure Testing Heater Gas Connections
1. Open equipment shutoff valve (see Figure 17).
2. Open main gas valve located on or near gas tank.

Supply
3. Make sure control knob of heater is in the OFF position.
4. Check all joints from equipment shutoff valve to control valve (see Figure 18). Apply
mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
5.
Correct all leaks immediately.
6 Light heater (see Operation, pages 23 through 28). Check the rest of the internal
joints for leaks.
