Supply Piping System
Test Pressures In Excess Of 1/2
PSIG(3.5kPa)
1. Disconnect heater 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 system
by either using compressed air or
opening gas supply tank valve.
4. Check all joints of gas supply

liquid soap and water to gas
joints. Bubbles forming show a
leak.

Less Than 1/2 PSIG(3.5 kPa
)
1. Close equipment shutoff valve
(see Figure 8).
2. Pressurize supply piping system
by either using compressed air
or opening gas supply tank valve.
3. Check all joints from gas meter to
