•
Ensure that the primary and secondary air

•
Ensure that the boiler water temperature is
below 90 ºC and that the thermostat indi-
cator lamp is on since the set value of the
extractor thermostat is 90 ºC.
•
Check the set value of the flue gas ther-
mostat.

Check that the temperature limiter has not
tripped. For acknowledgement, open the
protective cap and press the limiter. How-

before acknowledgement. Find out why

If the extractor fan produces abnormal
sound when working the trouble can be
caused by a motor bearing or a blade.

If the extractor power has dropped then
the blades have to be cleaned.
