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
using compressed air or opening gas sup-
ply valve.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 18).
2. Pressurize supply piping system by either
using compressed air or opening gas sup-
ply valve.
3. Check all joints from gas supply (see Fig-
ure 19 or 20) to equipment shutoff valve.
Apply a noncorrosive leak detection fluid
to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
