WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
1. Disconnect heater with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping sys-
tem. Pressures in excess of 1/2 PSIG will
damage heater regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 16).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
3. Check all joints from gas meter (natural
gas installations, see Figure 17) or from
propane/LP tank (propane/LP gas installa-
tions, see Figure 18) to equipment shutoff
valve. Apply a noncorrosive leak detection
fluid to all joints. If bubbles form, there is
a leak.
4. Correct all leaks at once.
