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 systems. Pressures in
excess of 1/2 psig (3.5 kPa) will damage
burner system gas regulator.
2.
Cap off open end of gas pipe where
equipment shutoff valve was con-
nected.
3.
Pressurize supply piping system by ei-
ther opening propane/LP supply tank
valve for propane/LP gas burner sys-
tem or opening main gas valve located
on or near gas meter for natural gas
burner system, or using compressed air.
4.
Check all joints of gas supply piping
system. Apply commercial leak test
solution to all gas joints. Bubbles form-
ing show a leak. Correct all leaks at
once.
5.
Reconnect burner system and equip-
ment shutoff valve to gas supply. Check
reconnected fittings for leaks.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply
commercial leak test solution to
all gas joints. Bubbles forming
show a leak. Correct all leaks at
once.
CONNECTING STOVE/
BURNER SYSTEM TO GAS
SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not
provided)
1.
Open lower door panel.
2.
Route flexible gas line (provided by
installer) from equipment shutoff valve
to burner system. Route flexible gas
supply line through slot in stove bot-
tom and attach to valve.
3.
Check all gas connections for leaks. See
Checking Gas Connections.

Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1.
Close equipment shutoff valve (see
Figure 45).
2.
Pressurize supply piping system by ei-
ther opening propane/LP supply tank
valve for propane/LP gas burner sys-
tem or opening main gas valve located
on or near gas meter for natural gas
burner system, or using compressed air.
3.
Check all joints from propane/LP sup-
ply tank or gas meter to equipment
shutoff valve (see Figure 46, page 21
for propane/LP or Figure 47, page 21
for natural). Apply commercial leak test
solution to all gas joints. Bubbles form-
ing show a leak. Correct all leaks at
once.
