STOVE AND DIRECT-VENT BURNER SYSTEM INSTALLATION
Continued
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged burner system valves.
WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 41, page 20. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into burner system gas controls. If sediment trap/drip leg is not installed or is installed wrong, burner system may not run properly.
CONNECTING STOVE/BURNER SYSTEM TO GAS SUPPLY
Installation Items Needed
•5/16" hex socket wrench or
•sealant (resistant to propane/LP gas, not provided)
1.Open lower door panel.
2.Route flexible gas line (provided by installer, see Figure 42) from equipment shutoff valve to burner system. Route flex- ible gas supply line and attach to valve.
3.Check all gas connections for leaks. See Checking Gas Connections, column 2.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply noncorrosive leak detection 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 (con- trol valve) and equipment shutoff valve from gas supply pip- ing systems. Pressures in excess of 1/2 psig (3.5 kPa) will dam- age burner system gas 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 burner system 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 noncorro- sive leak detection solution to all gas joints. Bubbles forming show a leak. Correct all leaks at once.
5.Reconnect burner system and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.
