UNPACKING ASSEMBLY (For 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.
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.
VENTILATION ! 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. 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.
OPERATION Continued Flame-Out Control Reset Button (Fan Guard Removed) Figure 8 - Flame-Out Control Reset Button, 150,000 BTU/Hr (Optional Extra) To Stop Heater 1. Unplug power cord from outlet.
