Never clean the refractory material with a damp cloth
or anything else, as it may be stained.
Use a dry paintbrush if necessary to remove heavy
soot build-up.
If the Alutec does not whiten, it is not to be
considered as a defect in light of the warnings and
instructions above.
7.1.4. Lubrication and routine maintenance of the
extensible guides
All of the doors of the fireplace stoves are mounted on extensible
ballbearing guides that ensure a robust, sturdy system that provides
silent movement.
Prolonged use and the heat of the fireplace stove gradually depletes the
lubricant in the guides. This will cause them to become less efficient
and noisier.
If necessary, periodically grease both runners as follows:
 Pull open the frame liner and extract the door so you can see
the tracks of the guide.
 Using the provided grease gun, apply two drops of grease,
about 5 mm in diameter, at the highest visible point of the
runners. Do not exceed the recommended amount!
 Perform this operation on both guides. Keep in mind that the
total amount of grease to be used is about 0.5ml (see
graduated scale on grease gun).
After lubrication:
 Put the glue gun back and conserve it
 Lower and raise the door completely at least 6 or 7 times so
that the grease is spread onto all of the other components of
the guides to complete lubrication. You should notice a
substantial improvement in ease of movement and noise
reduction.
It is advisable to carry out this operation at the end of
the season of use, or whenever the runners become
too noisy.
Do not use other types of grease. If the grease gun
runs out, request an MCZ original replacement.
7.1.5. Maintenance of kit VF (if installed)
The maintenance of all electrical parts (fan, control
unit, etc.) must only be carried out with no electrical
power supplied and with the unit unplugged.
7.1.5.1.
Electric fan
Periodically, and at least at the end of each winter, it is advisable to
clean the fan blades, which may have suctioned up dust or other small
foreign bodies due to the static pressure exercised by the fan along the
air ducts.
Clean the fan blades only with compressed air or with a vacuum
cleaner. Take care not to damage the rotor or the fan blades.
