(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 se-
cure.
3. Place heater on wheel support frame. Make sure air inlet end
(rear) of heater is over wheels. Line up holes on fuel tank
fl ange with holes on wheel support frame.
4. Place front handle and rear handle on top of fuel tank fl ange.
Insert screws through handles, fuel tank fl ange, and wheel
support frame. Attach nut fi nger tight after each screw is

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 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 43kw (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).

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 fi ne 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
thespark 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 fl ame goes out.

4.Plug power cord of heater into standard 230 volt/50 hertz,
grounded (earthed) outlet. Use an extension cord if needed.
Use only a three-prong, grounded (earthed) extension cord.
Extension cord wire size requirements:
Up to 30 meters (100 feet) long, use 1.0 mm² (16 AWG)
conductor.
30 to 61 meters (101 to 200 feet) long, use1.5 mm² (14 AWG)
conductor.

Note: If shipping, transport companies require fuel tanks to be
empty.
1. Drain fuel tank.
Note: Some models have drain plug on underside of fuel tank.
If so, remove drain plug to drain all fuel. If heater does not
have drain plug, drain fuel through fuel cap opening. Be sure
all fuel is removed.
2. Replace drain plug if provided.
3. If any debris is noted in old fuel, add 1or 2 quarts of clean
kerosene to tank,stir, and drain again. This will prevent excess
debris from clogging fi lters during future use.
4. Replace fuel cap or drain plug. Properly dispose of old and
dirty fuel. Check with local automotive service stations that
recycle oil.
5. If storing, store heater in dry place. Make sure storage place
is free of dust and corrosive fumes.
IMPORTANT: Do not store kerosene over summer months for
use during next heating season. Using old fuel could damage
heater.
