ASSEMBLY
(FOR BY100CEH AND BY150CEH MODELS ONLY)
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 3).
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 sup- port frame. Attach nut finger tight after each screw is inserted.
5.After all screws are inserted, tighten nuts firmly.

VENTILATION
WARNING: Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ven- tilation before running heater.
Provide a fresh air opening of at least 2800 square cm (three square feet) for each 30kw (100,000 Btu/Hr) rating. Provide extra fresh air if more heaters are being used.
Example: A 44kw (150,000 Btu/Hr) heater requires one of the following:
•a
•a
•two, 76 cm (30 inch) windows raised 28 cm (11 inches)
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 ignition control assembly provides power to the ignitor. This ignites the fuel/air mixture in the combus- tion chamber.
