Fuel Tank Flange Cap Nut ASSEMBLY, EURO PFA/PV 018AFigure 4 - Wheel and Handle Assembly, 90/150,000 BTU/Hr Models Only Screw Wheel Support Frame Wheel Nut Axle Extended Hub Air Inlet Rear Handle Front Handle Hot Air Outlet 5 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. 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.

Using heavy fuels will result in: • clogged fuel filter and nozzle • carbon build up on spark plug • use of non-toxic anti-icer in fuel during very cold weather IMPORTANT:Use a KEROSENE ONLY container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the flame-out control to shut down heater. Foreign matter may also require you to clean fuel system often. ! WARNING Use only kerosene or No. 1 fuel oil to avoid risk of fire or explosion. Never use gasoline, naphtha, paint thinners, alcohol or other highly flammable fuels. 6 099606 VENTILATION OPERATION 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 standard 230 volt/50 hertz, grounded (earthed) outlet. Use an extension cord if needed. Use only a three-wire, grounded (earthed) extension cord. Extension Cord Wire Size Requirements Up to 100 feet (30.5 meters) long, use 16 AWG (1.0 mm2) conductor 101 to 200 feet (30.6 to 61 meters) long, use 14 AWG (1.5 mm2) conductor Heater will start when power cord is plugged into outlet. If not, push in flameout control reset button (see Figures 6 thru 8). ! WARNING Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater. ! WARNING Review and understand the warnings in the Safety Information Section. They are needed to safely operate this heater. Follow all local codes when using this heater. Provide a fresh air opening of at least three square feet (2800 square cm) for each 100,000 BTU/Hr rating. Provide extra fresh air if more heaters are being used. Example: A 150,000 BTU/Hr heater requires one of the following: • a two-car garage door raised six inches (15.24 cm) • a single-car garage door raised nine inches (22.86 cm) • two, thirty-inch (76.20 cm) windows raised twelve inches (30.48 cm) Flame- Out Control Reset Button Figure 6 - Flame-Out Control Reset Button, 30/70,000 BTU/Hr Flame-Out Control Reset Button Figure 7 - Flame-Out Control Reset Button, 90,000 BTU/Hr Continued OPERATION Continued STORAGE PREVENTATIVE MAINTENANCE SCHEDULE Flame-Out Control Reset Button (Fan Guard Removed) Figure 8 - Flame-Out Control Reset Button, 150,000 BTU/Hr To Stop Heater 1. Unplug power cord from outlet. To Restart Heater 1. Wait 2 minutes after stopping heater. 2. Repeat steps under To Start Heater, page 7. 1. Drain fuel tank. Note:Some models have drain plug on underside of fuel tank. If so, remove drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed. 2. Replace drain plug if used. 3. Add one gallon (4 liters) of clean kerosene to fuel tank. 4. Attach fuel cap. 5. Move heater forwards and backwards to stir fuel. 6. Remove fuel cap or drain plug and drain fuel tank. Be sure all fuel is removed. 7. Replace fuel cap or drain plug. Properly dispose of old and dirty fuel. 8. 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. ! WARNING Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can occur. Item How Often...
