General Description
2.2 Heat exchanger
The heat generated by combustion in the heat exchanger is
given off to the cold air transported by the heating air fan.

Heat exchanger
2.3 Evaporator mount with combustion
pipe
The fuel is distributed via the metal fibre evaporator (fleece)
in the evaporator mount. The mixture of fuel and air burns in
the combustion chamber, thus causing the heat exchanger to
become hot.

The mixture of fuel and air is ignited by the glow plug when
the heater is started. The glow plug designed as an electrical
resistor is positioned in the burner assembly (evaporator
mount with combustion pipe) on the side facing the flame.
