6.4 Cleaning flue gas temperature sensor
During the worktime of the Pelling boiler, it is occasionally necessary to clean
the smoke sensor at the flue gas outlet immediately next to the fan.
Detail of the smoke sensor position
Due to the size of the sensor (diameter Φ=4mm), lot of attention should be paid
when removing the sensor from the hole of the flue fan outlet housing.
The procedure is:
1. Locate the metal bushing from the sensor in the output of the flue fan
housing.
2. The sensor must be carefully pulled out, use needle nose pliers for this
operation.
3. Clean the sensor with a cloth or sanding paper.
4. Replace (insert) sensor.
Note: The smoke sensor needs to be cleaned once a season!
