PORTABLE FORCED AIR HEATERS

ASSEMBLY

(FOR 100,000 AND 150,000 BTU/HR 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 sup- port 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.

VENTILATION

WARNING: Follow the mini- mum fresh, outside air ventila- tion requirements. If proper fresh, outside air ventilation is not pro- vided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ventilation be- fore 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 two-car garage door [4.9 meter (16 feet)

opening] raised 9 cm (3.5 inches)

• a single-car garage door [2.75 meter (9

feet) opening] raised 15.25 cm (6 inches)

• two, 76 cm (30 inch) windows raised 28

cm (11 inches)
