Introduction
The main equipment of the BISON 2000A air heater (hereinafter referred
to as ‘the heater’) is a small fuel furnace controlled by a single-chip micro-
processor. Its furnace body (the heat exchanger) is located in the hood
shaped case, which serves as an independent air passage. Cold air is drawn
into the air passage by the fan and blown out when it becomes hot.
The heat can be supplied by the heater to the driver’s cab and passenger’s
compartment independently from the engine. The schematic diagram is
shown in Fig I.
The heater is fully automatically controlled. It features a compact structure,
easy installation, low running costs, easy maintenance and is safe and
reliable.

The heat exchanger is made of die-cast aluminium, with radiating fins around
the rear. The combustion chamber fits inside the inner cavity of the heat
exchanger. The burner assembly and glow pin, fit into the end of the
combustion chamber. Fuel comes to the burner assembly through the fuel
pipe and is ignited by the glow pin. The flame is passed up the combustion
chamber and returns between the inner walls of the heat exchanger and
discharged through the exhaust outlet vent to the outside of the vehicle or
boat.
The air supporting combustion of the furnace, comes from the combustion air
inlet port and is sent down the combustion pipe by the combustion
supporting air blades of the fan motor.
