FUELS

WARNING: Use only kero- sene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels to avoid risk of fire or explosion. Never use gaso- line, oil drained from crankcases, naphtha, paint thinners, alcohol or other highly flammable fuels.

Use only kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels. Heavier fuels such as No. 2 fuel oil or No. 2 diesel fuel may also be used but will result in:

•noticeable odor

•additional fuel filter maintenance

•the need for nontoxic, anti-icer additives in very cold weather

Do not use fuels heavier than No. 2 grade or heavy oils such as oil drained from crankcases. These heavy oils will not ignite properly and will con- taminate the heater.

IMPORTANT: Use a KEROSENE ONLY (blue) or DIESEL ONLY (yellow) storage container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the ignition control as- sembly to shut down heater. Foreign matter may also require heater's fuel system to be frequently cleaned.

VENTILATION

WARNING: Provide a fresh air opening of at least three square feet (2,800 square cm) for each 100,000 Btu/hr rating. Provide extra fresh air if more heaters are being used. The mini- mum ventilation requirements must be followed to avoid risks associated with carbon monox- ide poisoning. Make certain these requirements are met prior to operating heater.

Example: A 200,000 Btu/Hr (58.6kw) heater re- quires one of the following:

•a two-car garage door [16 feet (4.88 meter) opening] raised 5 inches (12.7 cm)

•a single-car garage door [9 feet (2.74 meter) opening] raised 8 inches (20.3 cm)

•two, 30 inch (76.2 cm) windows raised 15 inches (38.1 cm)

THEORY OF OPERATION

The Fuel System: The air pump forces air through the air line. The air is then pushed through the nozzle. This air causes fuel to be lifted 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 ignition control assembly provides power to the ignitor. This ignites the fuel/ air mixture in the combustion chamber.

The Flame-Out Control System: This system causes the heater to shut down if the flame goes out.
