5. OVERVIEW OF HEATER’S DESIGN
Fuel System: This heater is equipped with an electric
air pump that forces air through the air
line connected to the fuel intake and then
through a nozzle in the burner head.
When the air passes in front of the fuel
intake it causes fuel to rise from the tank
and into the burner nozzle. This fuel and
air mixture is then sprayed into the
combustion chamber in a ne mist.
“Sure Fire Ignition” : The electronic ignitor sends voltage to a specially designed spark plug.
The spark plug ignites the fuel and air mixture described above.
The Air System : The heavy duty motor turns a fan that forces air into and around the combustion chamber.
Here the air is heated and then forced out the front of the heater.
The Safety System :
A. Temperature Limit Control : This heater is equipped with a Temperature Limit Control designed to turn
off the heater should the internal temperature rise to an unsafe level. If this
device activates and turns your heater off it may require service.
B. Electrical System Protection : This heater’s electrical system is protected by a fuse mounted to the PCB
assembly that protects it and other electrical components from damage.
If your heater fails to operate check this fuse rst and replace as needed.
C. Flame-Out Sensor : Utilizes a photocell to monitor the ame in burn chamber during normal operation.
It will cause the heater to shut-off should the burner ame extinguish.
