Provide at least a three-square-foot opening of fresh, outside air for each 100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used. Example: A 200,000 Btu/Hr heater requires one of the following: • a two-car garage door (16 feet wide opening) raised five inches • a single-car garage door (9 feet wide opening) raised eight inches • two windows (30 inches wide opening) raised fifteen inches Figure 2 - Wheel and Handle Assembly 4 102569 OWNER’S MANUAL OPERATION WARNING: Review and understand the warnings in the Safety Informationsection, page 2. They are needed to safely operate this heater. Follow all local codes when using this heater. TO START HEATER 1. Follow all ventilation and safety information. 2. Fill fuel tank with kerosene or No. 1 fuel oil. 3. Attach fuel cap. 4. Plug power cord of heater into three- prong, grounded extension cord. Extension cord must be at least six feet long. Extension Cord Wire Size Requirements 6 to 10 feet long, use 18 AWG rated cord 11 to 100 feet long, use 16 AWG rated cord 101 to 200 feet long, use 14 AWG rated cord 5. Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded outlet. Heater will start when extension cord is plugged into outlet. If not, push in flame-out control reset button (see Figure 4). TO STOP HEATER 1. Unplug extension cord from outlet. TO RESTART HEATER 1. Wait two minutes after stopping heater. 2. Repeat steps under To Start Heater. Flame-out Control Reset Button THEORY OF OPERATION The Fuel System: The air pump forces air through the air line. The air is then pushed through the burner head nozzle. This air causes fuel to lift from the tank. A fine mist of fuel is sprayed into the combustion chamber. Combustion Chamber Spark Plug Clean Heated Air Out Fuel Filter Fuel Nozzle Air Line Electronic Tank Air For Fuel Fuel Air For Combustion System And Heating Figure 3 - Cross Section Operational View 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 electronic ignitor sends voltage to the spark plug. The spark plug ignites the fuel and air mixture. The Flame-out Control System: This system causes the heater to shut down if the flame goes out.

WARNING: Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can occur. 1. Drain fuel tank. Item How Often How To Note: This model has a drain plug on underside of fuel tank. Remove drain plug to drain all fuel. Be sure all fuel is removed. 2. Replace drain plug. 3. If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent excess debris from clogging filters during future use. 4. Replace fuel cap and drain plug. Properly dispose of old and dirty fuel. Check with local automotive service stations that recycle oil. 5. If storing, store heater in dry place. Make sure storage place is free of dust and corrosive fumes. IMPORTANT: Do not store kerosene over summer months for use during next heating season. Using old fuel could damage heater. Fuel tank Flush every 150-200 hours of operation or as needed See Storing, Transporting, or Shipping Air output and lint filters Replace every 500 hours of operation or once a year See Air Output, Air Intake, and Lint Filters, page 8 Air intake filter Wash and dry with soap and water every 500 hours of operation or replace as needed See Air Output, Air Intake, and Lint Filters, page 8Fuel filter Clean twice a heating season or replace as needed See Fuel Filter, page 9 Spark plug Clean and regap every 600 hours operation or replace as needed See Spark Plug, page 10 Fan blades Clean each season or as needed See Fan, page 8 Motor Not required/permanently lubricated 6 102569 OWNER’S MANUAL TROUBLESHOOTING WARNING: Never service heater while it is plugged in, operating, or hot.
