Never use gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels. • Never use heater where gasoline, paint thinner, or other highly flammable vapors are present. • Follow all local ordinances and codes when using heater. • Use only in well-vented areas. Provide at least a three-square foot (2800 square cm) opening of fresh, outside air for each 29,3 kW (100,000 Btu/Hr) of rating. • Use only in places free of flammable vapors or high dust content. • Use only with the electrical voltage and frequency specified on model plate. • Use only a grounded (earthed) extension cord. • Minimum heater clearances from combustibles: Outlet: 250 cm (8 Ft.) Sides, Top, and Rear: 125 cm (8 Ft.) • Locate heater on a stable and level surface while hot or running or a fire may occur. • When moving or storing heater, keep heater in a level position or fuel spillage may occur. • Keep children and animals away from heater. • Unplug heater when not in use. • When used with thermostat, heater may start anytime. • Never use heater in living or sleeping areas. • Never block air inlet (rear) or air outlet (front) of heater. • Never move, handle, refuel, or service a hot, operating, or plugged-in heater. • Never attach duct work to front or rear of heater. Using duct work could reduce the necessary air flow of heater. Heater would produce excessive carbon monoxide. DANGER Carbon monoxide poisoning may lead to death! 3 4 099623 Fuel Cap Lower Shell Power Cord Upper Shell Figure 3 - 44 kW (150,000 Btu/Hr) Model Handle Fuel Cap Lower Shell Side Cover Fuel Tank Figure 1 - 8,8/20,5 kW (30/70,000 Btu/Hr) Models PRODUCT IDENTIFICATION Upper Shell Hot Air Outlet Hot Air Outlet Air Filter End Cover Fan Guard Power Cord Flame-Out Control Reset Button Figure 2 - 26,4 kW (90,000 Btu/Hr) Model Fan Guard Air Filter End Cover Flame-Out Control Reset Button Side Cover Fuel Tank Lower Shell Fuel Cap Fan Guard Power Cord Upper Shell Flame-Out Control Reset Button Hot Air Outlet Fuel Tank UNPACKING ASSEMBLY (For 26,4 and 44 kW [90,000 and 150,000 Btu/Hr] Models Only) 1. Remove all packing items applied to heater for shipment. 2. Remove all items from carton. 3. Check items for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater. These models are furnished with wheels and handles. Wheels, handles, and the mounting hardware are found in the shipping carton. Tools Needed • Medium Phillips Screwdriver • 3/8" Open or Adjustable Wrench • Hammer 1. Slide axle through wheel support frame. Install wheels on axle. IMPORTANT:When installing wheels, point extended hub of wheels toward wheel support frame (see Figure 4). 2. Place cap nuts on axle ends. Gently tap with hammer to secure. 3. Place heater on wheel support frame. Make sure air inlet end (rear) of heater is over wheels. Line up holes on fuel tank flange with holes on wheel support frame. 4. Place front handle and rear handle on top of fuel tank flange. Insert screws through handles, fuel tank flange, and wheel support frame. Attach nut finger tight after each screw is inserted. 5. After all screws are inserted, tighten nuts firmly.

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.
