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 (3.5 K Pa)

1.	Disconnect appliance with its appliance
	main gas valve (control valve) and equip-
	ment shutoff valve from gas supply pip-
	ing system. 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.
3.	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 gas meter to equipment shutoff valve (see Figure 14). 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 equipment shutoff valve (see Fig- ure 13).

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 equipment shutoff valve to control valve (see Figure 14). 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 10 and 11). Check the rest of the internal joints for leaks.
