3Operation
3.1System Description
The Cub series Air Heater machines are indirect-fired air heaters. The
Cub series Air Heater machines incorporate aluminized steel shells
and heat exchangers. The machines run on three fuel options: diesel,
Kerosene, or winter blend diesel (winter blend diesel is treated with
anti-gelling conditioners for use in cold weather). The fuel is consumed
in a closed combustion chamber. The exhaust gasses must be vented
outdoors through a vent pipe. The clean, dry hot air is recirculated by
means of an enclosed blower.
The Cub series Air Heater machines are intended to heat air on
construction sites and in other rugged environments. Do not use the
machines for any other purpose.
3.2Installing the Lift Brackets
See graphic ghi_gr005931
Before attempting to lift the Cub 200 and 300 models, the lift brackets
must be installed.
3.2.1Remove the machine from the crate.
3.2.2Intstall the four lift brackets (a) as shown using the supplied bolts and
washers.

The Cub series Air Heater machines are shipped partially assembled.
Before operating either machine, use the following procedure to mount
the handles and base assembly. This assembly includes the handle,
base support, and wheels with axles.
Note: There are pre-drilled bolt holes for all the components installed
within this procedure.
Note: The Cub 300 HD requires that only the handle be attached.
Refer to the procedure below to install the handle.
3.4.1Attach the axles to the sides of the fuel tank using the supplied bolts
and washers.
3.4.2Install the wheels using a rubber mallet to secure them to the axle
ends.
3.4.3Attach the base support to the rear of the fuel tank using the supplied
bolts and washers.
3.4.4Attach the handle to the machine using the supplied bolts (and
washers, if applicable).

3.5Machine Location
The Air Heater machines may be located outdoors or in any
environment that requires heating. When locating a machine within the
area to be heated, the exhaust gases must be vented to the outdoors.
The machines must be installed:
•By qualified personnel who have read and understood all
supplied instructions.
•On a flat, firm surface.
•With the following minimum clearances:
•3.05 m (10 ft.) to front.
•0.61 m (2 ft.) to rear.
•0.61 m (2 ft.) to sides.
•1.52 m (5 ft.) to top.
•0.915 m (3 ft.) to flue pipe.
3.6Suggested Venting

Exhaust gas from this machine CAN KILL YOU IN MINUTES. The
exhaust contains carbon monoxide, a deadly poison you can not see
or smell. This machine must be properly vented to reduce the risk of
WARNING
carbon monoxide poisoning.
When installing vents:
•Adhere to all local and national codes.
•Consult all appropriate governing bodies or local contractor for
venting and fresh air requirements.
•Place the machine in a manner that avoids excessive vent bends
(elbows), and long horizontal runs.
•Keep air inlets and outlets free from obstruction.
•Route the venting pipes in a manner that avoids any flammable
material.
•Route the venting pipes in a manner that avoids contact with
humans.
