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
located on or near gas meter for natural
gas or using compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply a noncorrosive leak detection
fluid to gas joints. If bubbles form, there
may be a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
fittings for leaks.
Test Pressures Equal To or Less
Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 17).
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 18 or 19) to equipment shutoff valve.
Apply a noncorrosive leak detection fluid
to all 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 17).
2. Open main gas valve located on or near
gas meter for natural gas or open propane
gas supply tank valve.
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 or
