Notes on repairing the stationary heater - AH83.70-P-0001-03C

The heater can be dismantled into the following components during repair work:
- Combustion air blower unit
- Burner insert
- Retrofitted control unit/heat exchanger unit
The stationary heater is protected with two separate fuses (heater and timer) which are located at the right in the engine compartment near the spring tower.
During a fault shutoff the heater interrupts the heating program and switches to power-down. The fault shutoff can be canceled by switching the heater off and on again.
