CHECKING GAS CONNECTIONS
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
using compressed air or opening gas sup-
ply valve.
WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
ame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. If bubbles form, there
is a leak. Correct all leaks at once.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
4. Check all joints of gas supply piping
system. Apply mixture of liquid soap and
water to gas 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 14).
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 15 or 16) to equipment shuto valve.
Apply a noncorrosive leak detection uid
to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
