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 ame to check for a leak.
Apply a noncorrosive leak detec-
tion 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
replace. See guidelines under
Connecting to Gas Supply,
page 16.

6. Replace branch support back into re-
place. Feed exible gas line into replace
base area while replacing branch support.
Make sure the entire exible gas line is
in replace base area. Reattach branch
support to replace with screws removed
in step 2, page 17.
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 will dam-
age 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
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
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
19). Apply a noncorrosive leak detection
uid to gas joints. Bubbles forming show
a leak.
4. Correct all leaks at once.
