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 flame to check for a leak.
Apply a noncorrosive leak detec-
tion fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
CAUTION: Make sure ex-
ternal regulator has been in-
stalled between propane/LP
supply and appliance. See
guidelines under
Connecting to
Gas Supply
, page 7.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its individual
equipment shutoff valve from gas supply
piping system. Pressure 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 gas
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect log set and equipment shutoff
valve to gas supply. Check reconnected fit
-
tings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 8).
2. Pressurize supply piping system by either us
-
ing compressed air or opening main gas valve
located on or near gas meter.
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 9 or 10). Apply noncorrosive
leak detection fluid to all joints. Bubbles form
-
ing show a leak.
4. Correct all leaks at once.
