Application of the SF2300 Air Heater
The SF2300 Air Heater is designed to be used as an auxiliary and sometimes primary heater in car, trucks,
RVs, boats, buses, construction and farm equipment. The heater provides heat using the vehicles fuel and
battery power without the need for the vehicle engine to waste fuel by idling just to provide heat. The
SF2300 Heaters compact design, ease of use, low maintenance and low operating cost make it ideal for
many mobile application where and efficient manner of providing heat is required.

D. Fuel Intake
How the SF2300 Air Heater Works
The external fuel pump delivers fuel to the combustion chamber, the blower motor delivers outside
combustion air to the burner chamber and a glow pin is used to ignite the fuel-air mixture to create heat.
The heat from the burner is transferred into the heat exchanger while the exhaust gases are expelled to the
exterior of the vehicle. The process air from the area to be heated is circulated through the heater over the
outside of the heat exchanger with the blower wheel which warms the interior of the vehicle. The heater
automatically maintains the desired set temperature in the vehicle to keep the operator and or passengers
comfortable.
