• The controller sends a starting signal to the heater
• An automatic safety check is performed
• The combustion chamber is pre-ventilated

• The fuel and air mixture is ignited
• Hot combustion gases pass through the heat exchanger
• The fan draws in cabin or fresh air
• Heat is transferred through the heat exchanger and distributed as warm air
