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 (see Figure 30). Route flexible gas supply line and attach to valve.

3.Check all gas connections for leaks. See Checking Gas Connections.

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.

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-

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
