CHECKING GAS CONNECTIONS
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 detec-
tion fl uid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
fi replace. See guidelines under

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 equip-
ment shutoff valve from gas supply piping.
Pressures in excess of 1/2 psig (3.5 kPa)
will damage fi replace regulator.
2. Cap off open end of gas pipe where equip-
ment 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 sys-
tem. Apply a noncorrosive leak detection
fl uid to gas joints. Bubbles forming show
a leak.
5. Correct all leaks at once.
6. Reconnect heater 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
Fig-
ure 25
).
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 for natural
or propane/LP supply to equipment shut-
off valve
(see
Figures 26 and 27, Page
21
).
Apply a noncorrosive leak detection
fl uid to gas joints. Bubbles forming show
a leak.
4. Correct all leaks at once.
