The burner gaskets must be replaced at
every cleaning operation.

During this operation it will be necessary to ascertain that
the condensate drain pipe is free, so that the washing water
does not come out from the inspection hole.
Blow the combustion chamber with compressed air, trying to
remove all the dirt still fixed to the fins.
Once the washing of the aluminium sections is finished, make
sure the siphon for the evacuation of the condensate is free:
if necessary clean it
Ispect the smoke evacuation pipe and the chimney
Third phase – Reassembly
When reassembly, proceed in the reverse
order, taking care to tight the fixing screws
of the mixer/fan group to the body, with a
