WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
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 supply tank valve for
propane gas or opening main gas valve
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 14).
2. Pressurize supply piping system by either
opening propane supply tank valve for
propane 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 supply (see Fig-
ure 15 or 16) to equipment shutoff valve.
Apply a noncorrosive leak detection fluid
to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
