As soon as the heater receives its starting pulse, the following processes are triggered by the central control unit:
• Automatic safety check.
• The burner motor starts, the combustion space is pre-ventilated, the glow plug is warmed up, the metering pump conveys fuel.
• The glow plug ignites the fuel-air mixture, the flame is formed.
• The hot combustion gases flow through the heat exchanger.
• The hot air fan draws in room air or fresh air.
• The heat of the combustion gases is transferred by the heat exchanger to this hot air.
