Operation description
The
2
0
00t
heaters are forced air Paraffin heaters without an exposed flame.
The
2
0
00t
models take combustion air from outside the boat through the outer
coaxial exhaust gas pipe and blow their exhaust out through the inner
coaxial pipe.
The coaxial pipe connects to a common through hull fitting that allows both inlet air
and exhaust to pass separately. This process improves efficiency,
wind resistance
and lowers the minimum power level.
The heat generated by forced air fuel combustion, is transferred to the circulation
air by a heat exchanger. The heating power can be adjusted freely between high
and low output settings by manual rheostat control or by thermostat.
The heated air is circulated through the cabin through the warm air ducting.
In hot and/or humid conditions, these heating units can be used for simple fresh air
ventilation and circulation.
When starting the device, the glow plug ignites the pumped fuel in the burner bowl.
The glow/start and shut down sequences are factory programmed, so - starts and
stops are automatically controlled.
The fuel pump inside the heater case regulates the fuel feed and the system
electronics control both the fuel and air mixture to maintain the ideal clean burning
process. The temperature sensor inside the burner feels the ignition and lights up
the red signal light (1) to indicate a successful start. When stopping the device, an
automatic after cooling process takes place. This process cleans the burner, purg-
ing any unburned fuel.
The heaters are completely made out of corrosion resistant materials.
