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 will damage appliance regulator.
2. Cap off open end of gas pipe where equipment shutoff valve was
connected.
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 fluid 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 fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 13).
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 propane/LP (see Figure 14 or Figure 15, Page 11). Apply
noncorrosive leak detection fluid to all joints. Bubbles forming
show a leak.
4. Correct all leaks at once.
PRESSURE TESTING APPLIANCE GAS CONNECTIONS
1. Open equipment shutoff valve (see Figure 13).
2. Open main gas valve located on or near gas meter for natural gas
or open propane/LP supply tank valve.
3. Make sure control knob of appliance is in the OFF position.
4. Check all joints from gas meter to equipment shutoff valve for
natural gas or propane/LP supply to equipment shutoff valve for
propane/LP (see Figure 14 or Figure 15, Page 11). Apply noncor-
rosive leak detection fluid to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light appliance (see Operation, Page 16). Check all other internal
joints for leaks.
7. Turn off appliance (see To Turn Off Gas to Appliance, Page 16 for
Remote Ready models).

CAUTION: Avoid damage to gas control. Hold gas
control with wrench when connecting it to gas piping
and/or fittings.
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 flame to check for
a leak. Apply a noncorrosive leak detection fluid 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.

CHECKING GAS CONNECTIONS
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
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).
