SUN VALLEY STOVE COMPANY
VENT-FREE PROPANE/LP GAS STOVE HEATER
INSTALLATION
Continued
CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.
Install sediment trap in supply line as shown in Figure 19, page 11 and Figure 20. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is in- stalled wrong, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.
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 a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater. See guidelines under Con- necting to Gas Supply, page 11.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appli- ance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in ex- cess of 1/2 psig will damage heater regulator.
2.Cap off open end of gas pipe where equipment shutoff valve was con- nected.
3.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.
5.Correct all leaks at once.
6.Reconnect heater and equipment shutoff valve to gas supply. Check re- connected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 21).
2.Pressurize supply piping system by either using compressed air or opening propane/ LP supply tank valve.
3.Check all joints from gas meter to equip- ment shutoff valve (see Figure 22). Ap- ply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
4.Correct all leaks at once.
Pressure Testing Heater Gas Connections
1.Open equipment shutoff valve (see Fig- ure 21).
2.Open propane/LP supply tank valve.
3.Make sure control knob of heater is in the OFF position.
4.Check all joints from equipment shutoff valve to control valve (see Figure 22). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light heater (see Operating Heater, pages 14 through 17). Check all other internal joints for leaks.
7.Turn off heater (see To Turn Off Gas to Appliance,
