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

leaks at once.
Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of
1/2 PSIG (3.5 K Pa)
1. Disconnect appliance with its
appliance main gas valve
(control valve) and equipment
shutoff valve from gas supply
piping 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 connected.
3. Pressurize supply piping
s y s t e m b y e i t h e r u s i n g
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 forming show
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 K Pa)
1. Close equipment shutoff valve
(see Figure 13).
2. Pressurize supply piping system
by either using compressed air
or opening main gas valve
located on or near gas meter.
3. Check all joints from gas meter to
equipment shutoff valve (see
Figure 14). Apply mixture of
liquid soap and water to gas
joints. Bubbles forming show
a leak.
4. Correct all leaks at once.
Pressure Testing Heater Gas
Connections
1. Open equipment shutoff valve
(see Figure 13).
2. Open main gas valve located on
or near gas meter.
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 14 ). Apply mixture of
liquid soap and water to gas
joints. Bubbles forming show
a leak.
5. Correct all leaks at once.
6. Light heater (see Operating
Heater page 11 ). Check the rest
o f t h e i n t e r n a l j o i n t s f o r
leaks.
