LEANING

THE

FLUE

GAS

TEMPERATURE

SENSOR

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

Loosen the M10 union nut (SW 17) (2) and pull the flue gas
temperature sensor (1) out of the clamp screw connections.

Clean the sensor surface with a moist cloth.

Mount the flue gas temperature sensor (1) in the reverse
sequence.

✓

The flue gas temperature sensor has been cleaned.

Important!

✎

Observe the “Generally applicable safety instructions” in this
section.

Figure 7/5 - Cleaning the flue gas temperature sensor

The flue gas temperature sensor must be installed so that the
sensor element projects approx. 2 cm out of the clamp screw.
