6. MAINTENANCE AND CLEANING
ATTENTION!
All cleaning operations of all parts should be
conducted with the fireplace stove cold.
6.1. CLEANING TO BE PERFORMED BY THE USER
6.1.1. Cleaning the glass
Specific products can be used to clean the glass (see our price list), a
cloth dampened with water and ammonia or a bit of white ash and a
newspaper.
To open the flap door in order to clean the inside of the glass,
completely lower the fire door A and block the left-hand sliding guide
by pulling on lever B. Insert the provided key C in the lock located in
the middle of the left hand side of the structure of the fire door and
turn the key clockwise to unlock. Open the door as shown in figure 30.
To close, perform the steps listed above in reverse order.
ATTENTION!
Do not spray the product on the painted parts or on
the gaskets of the door (ceramic fibre cord)
6.1.2. Cleaning out the ashes
This must be done when the fireplace stove is off and cold.
It is advisable to adequately clean the ash drawer for proper
combustion.
Ashes which are still hot must neither be dumped outside in an
uncontrolled manner nor put in the dustbin. Leave them to cool
down in the open air in a metal container.
Using the hook provided, rotate the grille in its housing and lean it
against the back of the stove. Raise and extract the ash drawer and
empty it in a fireproof container (metal bucket).
Once the drawer is emptied, put in back in place by performing the
previous step in reverse.
6.1.3. Cleaning the refractory material walls (ALUTEC
® )
They do not require any cleaning, since the feature of this material
(ALUTEC ® ) is that it does not absorb soot but rather repels it when the
fire box is hot. After the lighting phase, during which they tend to
blacken, the refractory materials will turn white again, starting from the
base of the flame, when the combustion chamber reaches its operating
temperature (~ 400° C).
If this does not happen, it may be due to the following:
• Humid or resinous wood that does not release enough heat or
that dirties the combustion chamber (see chapter 5.3)
• Flue pipe with poor performance resulting in smoke remaining
too long in combustion chamber, dirtying the fire box.
