CLEANING THE EXHAUST SIDE
Access the combustion chamber (see section 7.3). Check that the
exhaust passages are clear; if there are deposits present, wash the
exchanger with compressed air, water or a vinegar-based detergent.
NOTE: it is possible to use a brush in order to mechanically remove
the residues.
Use of detergents:
-
soak the blades well
-
allow the detergent to act for about 20 minutes
-
rinse with a strong jet of water to remove the deposits (the
control panel must be kept closed)
-
make sure that there are no traces of detergents in the
exchanger.
CLEANING THE WATER SIDE
Use detergents that dissolve CaCO3. Leave to act for a short time
and then rinse. Make sure that the detergent does not remain inside
the exchanger.
To clean the condensate trap it is simply necessary to unscrew the
lower part of the condensate trap and clean it. Lastly, fill it with water
and replace the stopper.
