Only)
INSTALLATION
Continued
Test Pressures Equal To or Less Than 1/2 PSIG
(3.5 kPa)
1. Close equipment shutoff valve
(see
Figure 25
).
2. Pressurize supply piping system by either open-
ing 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 sup-
ply to equipment shutoff valve for propane/LP
(see
Figures 26 or 27
)
. Apply noncorrosive leak
detection fl uid to all joints. Bubbles forming show
a leak.
4. Correct all leaks at once.

WARNING: Test all gas piping and
connections, internal and external to
unit, for leaks after installing or servic-
ing. 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

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 heater
regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either open-
ing 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. Ap-
ply noncorrosive leak detection fl uid to all joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect fi replace and equipment shutoff valve to
gas supply. Check reconnected fi ttings for leaks.
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).
