1-1. Introduction
The Laser Heating System is a completely new type of sophisticated and fuel-efficient
vented system featuring its own housing, combustion and air circulation system and a
microcomputer control system.
In addition to superior design and technology, serious testing for quality and safety has
made the Laser Heating System unmatched for efficiency, convenience, economy and
flexibility. Plus, the Laser is easy to maintain and requires minimal service.
The following section outlines the Laser Heater and its various components.

1-3. Description of Functions
Fuel is delivered by the solenoid fuel pump to the burner assembly through the fuel
nozzle. Simultaneously air is delivered by the blower fan to the burner assembly through
small holes located on the inside burner wall. At the starting, the igniter heats up and
vaporizes the incoming fuel and results in ignition. Once combustion has started, it
continues in the heated burner as long as fuel supply continues.
The blower motor also drives the circulation fan to blow air through the heat exchanger
and therefore, cool air comes out from air outlet for a short time.
Once it reaches to the desired cabin temperature, the heater turns to the low mode. The
heater will run at three stages
“
HIGH
”
,
“
LOW
”
and
“
OFF
”
to maintain the desired
temperature setting.
