The propane gas moves through the solenoid valve and out the nozzle. OPERATION The Air System: The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air. The Ignition System: The direct spark ignitor (DSI) sends voltage to the ignitor. The ignitor ignites the fuel and air mixture. The Safety Control System: This system causes the heater to shut down if the flame goes out.

PROPANE Use this heater only with a propane vapor withdrawal supply system. See Chapter SUPPLY 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/ NFPA 58 and/or CAN/CGA B149.2. Your local library or fire department will have this booklet. The amount of propane gas ready for use from propane tanks varies. Two factors decide this amount: 1. The amount of propane gas in tank(s) 2. The temperature of tank(s) The chart below shows the number of 100 pound tanks needed to run this heater. Do not operate this product with any tank smaller than 100 pounds. Temperature (°F) At Tank 32° 20° 10° 0° -10° -20° Number of tanks 2 2 3 3 (Use larger tank) Less gas is vaporized at lower temperatures. You may need two or more 100 pound tanks or one larger tank in colder weather. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding-air temperature rating for this heater is -20°F (-29°C). INSTALLATION ! WARNING Review and understand the warnings in the Safety Information Section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater. ! WARNING Test all gas piping and connections for leaks after installing or servicing. 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. 1. Provide propane supply system (see Propane Supply above). 2. Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL fitting counterclockwise into threads on tank. Tighten firmly using wrench. IMPORTANT:Tighten regulator with vent pointing down. Pointing vent down protects regulator from weather damage.
