CAST IRON STOVE AND B-VENT BURNER SYSTEM INSTALLATION
Continued
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 28, page 13. 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) from equipment shutoff valve to burner system (see Figure 29). Route flexible 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, internal and external to unit, 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 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 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 test 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.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 30).
2.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.
3.Check all joints from propane/LP supply tank or gas meter to equip- ment shutoff valve (see Figure 31 for propane/LP or Figure 32 for natural, page 15). Apply noncorrosive leak test solution to all gas joints. Bubbles forming show a leak. Correct all leaks at once.
