5. OVERVIEW OF HEATERS DESIGN
The Fuel System :
This heater is equipped with a high-pressure electronic pump. The pump draws fuel up from the fuel tank to
the nozzle in the burner head. It is sprayed into the combustion chamber in a fine mist where it is mixed
with air for combustion.
The Air System :
A blower motor assembly forces air around the combustion chamber, where it is super-heated and forced
out the front of the chamber. A cooling fan blows air up and around the chamber during operation and also
runs during the cool-down period.
The Ignition System :
The electronic ignitor sends High voltage to a specially designed Spark Plug.
The Spark Plug ignites the fuel and air mixture described above.
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.
Once the temperature falls below the reset temperature you will be able to start your heater.
B. Electrical System Protection :
The heater's electrical system is protected by a fuse mounted to the
PCB assembly that protects the system components from damage.
If the heater fails, check the fuse first, and replace if necessary.
C. Flame-Out Sensor :
The heater uses photocell to see the flame in the combustion chamber.
Should the flame extinguish, the sensor will stop electrical current and the
heater will shut off.
D. Shock(earthquake) automatic shut-off Device : This Heater is equipped with Tip Over switch,
In case that earthquake more than 5magnitude happens
or that heater inclined 5~10 degrees.
Heater will be shut-off by Tip Over switch for safety.

6. FUELING YOUR HEATER
NEVER FILL THE HEATER FUEL TANK IN THE LIVING SPACE : FILL THE TANK OUTDOORS.
DO NOT OVERFILL YOUR HEATER AND BE SURE HEATER IS LEVELED.
IMPORTANT NOTICE REGARDING FIRST IGNITION OF HEATER :
The first time you light the heater, it should be done outdoors. This allows the oils, etc. used in
manufacturing the heater to burn off outside.
WARNING!! :
NEVER REFILL HEATER FUEL TANK WHEN HEATER IS OPERATING OR STILL HOT.
