9.4 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 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 fine mist.
The electronic ignitor sends voltage to a specially designed spark plug. The spark plug ignites the
fuel and air mixture described.
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.
9.5 THE SAFETY SYSTEM
Temperature Limit Control: This heater is equipped with a Temperature Limit Control designed to
turn the heater off should the internal temperature rise to an unsafe level. If this device activates
and turns your heater off, it may require service.
Once the temperature falls below the reset temperature, you will be able to start your heater.
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, have this fuse checked first and replace as needed.
Flame-Out Sensor: Utilizes a photocell to monitor the flame in burn chamber during normal
operation. It will cause the heater to shut off should the burner flame extinguish.
