The cabin heater utilizes engine coolant as a heat source. The fan and coil are located between the pilot and passenger rudder pedals. The control is located on the center console. When the control is off, the coolant valve is closed and the fan is off. When the control is turned clockwise, the coolant valve opens fully and the fan turns on. Further rotation of the control clockwise increases the fan speed providing additional heat to the cabin.

ICON Aircraft does not allow for any repairs to be made to the cabin heater without prior consent. Any cabin heater repairs needed must be coordinated and approved by ICON through the Major Repair and/or Alteration (MRA) process or handled directly by ICON.
