* Purchase the optional equipment shutoff valve from your
dealer.
**Minimum inlet gas supply pressure for purpose of input
adjustment.
CAUTION: Avoid damage to gas control.
Hold gas control with wrench when connect-
ing it to gas piping and/or fi ttings.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connec-
tions, 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, Page 8.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
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 pro-
pane/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 noncor-
rosive 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 13).
2. Pressurize supply piping system by either opening pro-
pane/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
10). Apply noncorrosive leak detection fl uid 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, Page 9 or Figure
15, Page 10). Apply noncorrosive leak detection fl uid to all
joints. Bubbles forming show a leak.
