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
shuto󰀨 valve from gas supply piping sys-
tem. Pressures in excess of 1/2 PSIG will
damage heater regulator.
2. Cap o󰀨 open end of gas pipe where equip-
ment shuto󰀨 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 noncorrosive leak detection
uid to all joints. If bubbles form, there
may be a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shuto󰀨
valve to gas supply. Check reconnected
ttings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shuto󰀨 valve (see Fig-
ure 15).
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 meter to equip-
ment shutoff valve for natural gas or
propane supply to equipment shuto󰀨 valve
for propane (see Figure 16 or 17). Apply
a noncorrosive leak detection uid to all
joints. Bubbles forming show a leak.
4. Correct all leaks at once.
