Burner Insert

The burner insert includes the:

• combustion pipe fuel cross section
• glow plug/flame sensor

Inside the burner insert, fuel is distributed across the combustion-pipe fuel cross section. Combustion of the fuel/air mixture takes place within the combustion pipe to heat the exchanger. The glow plug/flame sensor, located in the burner insert, ignites the fuel/air mixture during heater start up. After heater start up, the glow plug/flame sensor operates in the flame sensor function. The glow plug/flame sensor is an electrical resistor by design, and is located in the burner insert opposite the flame side.
