3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fl uid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect appliance and equipment shutoff
valve to gas supply. Check reconnected fi ttings
for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG
(3.5 kPa)
1. Close equipment shutoff valve
(see
Figure
15
).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP
supply to equipment shutoff valve for pro-
pane/LP
(see
Figure 16
or
Figure 17, Page
16
).
Apply noncorrosive leak detection fl uid
to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.

CAUTION: Avoid damage to gas
control. Hold gas control with wrench
when connecting it to gas piping and/
or fi ttings.
WARNING: Test all gas piping and
connections, internal and external
to unit, for leaks after installing or
servicing. Correct all leaks at once.
WARNING: Never use an open
fl ame to check for a leak. Apply a
noncorrosive leak detection fl uid to
all joints. Bubbles forming show a
leak. Correct all leaks at once.
CAUTION: Make sure external
regulator has been installed between
propane/LP supply and appliance. See
guidelines under
Connecting to Gas
Supply

CHECKING GAS CONNECTIONS
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
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 (3.5 kPa) will
damage appliance regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system
at test pressures
in excess of
1/2 psi (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing its equipment
shutoff valve during any pressure testing of the
gas supply piping system at test pressures
equal
to or less than
1/2 psi (3.5 kPa).
