Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 31).
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 32 for pro-
pane/LP or Figure 33 for natural, page
15). Apply commercial leak test solu-
tion to all gas joints. Bubbles forming
show a leak. Correct all leaks at once.
Pressure Testing Burner
System Gas Connections
1. Open equipment shutoff valve (see Fig-
ure 31).
2. Open propane/LP supply tank valve for
propane/LP burner system or main gas
valve located on or near gas meter for
natural gas burner system.
3. Make sure control knob of burner sys-
tem is in the OFF position.
4. Check all joints from equipment shutoff
valve to thermostat gas valve (see Fig-
ure 32 for propane/LP or Figure 33 for
natural, page 15). Apply commercial
leak test solution to all gas joints.
Bubbles forming show a leak. Correct
all leaks at once.
5. Light burner system (see Lighting In-
structions, page 19). Check all other in-
ternal joints for leaks.
6. Turn off burner system (see To Turn Off
Gas to Appliance, page 19).

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.
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 (see Figure 30). Route
flexible gas supply line and attach to
valve.
3. Check all gas connections for leaks. See
Checking Gas Connections.
