Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 21). Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" or greater diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur. Propane/LP Supply Tank External Regulator Vent Pointing Down Figure 20 - External Regulator with Vent Pointing Down CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. Install sediment trap in supply line as shown in Figure 21. 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 installed wrong, heater may not run properly. CAUTION: Avoid damage to control. Hold gas fitting with wrench when connecting it to gas piping and/or fittings.

Correct 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 external regulator has been installed between propane/LP supply and heater. See guidelines underConnecting to Gas Supply, page 13. Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG 1. Disconnect heater and its individual manual shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator. 2. Cap off open end of gas pipe where manual shutoff valve was connected. 3. Pressurize supply piping system by either 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 forming show a leak. 5. Correct all leaks at once. 6. Reconnect heater and manual shutoff valve to gas supply. Check reconnected fittings for leaks. Test Pressures Equal To or Less Than 1/2 PSIG 1. Close manual shutoff valve (see Figure 22). 2. Pressurize supply piping system by either using compressed air or opening propane/LP supply tank valve. 3. Check all joints from propane/LP supply tank to manual shutoff valve (see Figure 23). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 4. Correct all leaks at once. Open Manual Shutoff Valve Closed Figure 22 - Manual Shutoff Valve Pressure Testing Heater Gas Connections 1. Open manual shutoff valve (see Figure 22). 2. Open propane/LP supply tank valve. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from manual shutoff valve to thermostat gas valve (see Figure 23). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6. Light heater (see Operating Heater, pages 15 and 16). Check all other internal joints for leaks. 7. Turn off heater (see To Turn Off Gas to Appliance, page 15). 8. Replace front panel.

A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electric switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. • If you cannot reach your gas supplier, call the fire department. C. Use only your hand to push in or turn th...
