SENSOR

Allow the fire in the boiler to burn out and cool off.

Remove the upper cover (1) by lifting it upward.

Loosen the M10 union nut (SW 17) (3) and pull the flue gas
temperature sensor (2) out of the clamp screw connections.

Clean the sensor surface with a moist cloth.

Reinstall the flue gas temperature sensor (2) in the reverse
sequence.

Close the boiler in the reverse order.

✓

The flue gas temperature sensor has been cleaned.
