Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1.
Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2
psig will damage heater regulator.
2.
Cap off open end of gas pipe where
equipment shutoff valve was con-
nected.
3.
Pressurize supply piping system by ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.
4.
Check all joints of gas supply piping
system. Apply mixture of liquid soap
and water to gas joints. Bubbles form-
ing show a leak.
5.
Correct all leaks at once.
6.
Reconnect heater and equipment
shutoff valve to gas supply. Check re-
connected fittings for leaks.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. Bubbles forming
show a leak. Correct all leaks at
once.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1.
Close equipment shutoff valve (see Fig-
ure 21).
2.
Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.
3.
