7.6 Ash box
Open the door and extract the ash box (Fig. 34). Use a vacuum to remove all the ash de-
posited within. This operation must be performed more or less frequently depending on
the quality of the pellets used.
7.7 Cleaning the glass
The glass is a self cleaning type, therefore, while the stove is working, a veil of air is
blown across its surface to remove ash and dirt; nevertheless over a period of several
hours, a greyish patina tends to form which should be cleaned when the stove is next
shut down. How dirty the glass becomes also depends on the quality and quantity of
pellets used. Cleaning the glass should be done when the stove is cold with products
recommended and tested by our company.
When performing this operation, always check that the grey seal around the glass is in
a good state; failure to check the efficiency of this gasket can compromise the function
of the stove. Poor quality pellets can, in any case, cause the glass to become dirty.
WARNING!
If the glass is broken, do not attempt to light the stove.
7.8 Cleaning the clearing system
Until a reasonable experience is acquired regarding the operating conditions, it is advi-
sable to perform this maintenance on at least a monthly basis.
• Remove the electrical feed cable;
• Remove the cap from the T-joint and proceed with the cleaning of the ducts. If neces-
sary, at least for the first few times, call in qualified personnel;
• Carefully clean the smoke discharge system: for this, contact a professional chimney
sweep;
• Once a year clean the dust, cobwebs, etc. from the zone behind the internal covering
panels, paying particular attention to the fans.
7.9 Cleaning the fans
The stove is furnished with fans (environmental and smoke) positioned at the rear and
below the stove. Eventual deposits of dust or ash on the blades of the fan can cause an
imbalance in the fans leading to noisy performance.
It is, therefore, necessary to clean the fans at least once a year.
Since said operation requires dismantling several parts of the stove, have the fans clea-
ned only by our Technical Assistance Centre.
7.10 Season end cleaning
At the end of the season, when the stove will not be used for some time, it is advisable
to perform a thorough and general cleaning:
• Remove all the pellets from the container and the screw feeder;
• Carefully clean the brazier, the brazier support, the combustion chamber and the ash
box.
Once the preceding points have been observed, it only means that the state of the stove

Fig. 34
has been verified. It is necessary to thoroughly clean the smoke discharge tube or flue
and check the condition of the basket. If necessary, order a new one from our Authorized
Assistance Centre. If necessary, lubricate the hinges of the door and the handle. Also
check the ceramic fibre cord near the glass, on the internal wall of the door; if it is worn
or too dry, order a new one from the Authorized Assistance Centre.
8.0 Replacing elements
8.1 Replacing the glass
The stove is furnished with a 4 mm thick ceramic glass that is resistant to a thermal
shock of 750°C; the glass can break only from a strong impact or from improper use.
Do not slam the door or hit the glass.
In case of breakage, replace the glass only with an original replacement furnished by
the Authorized Assistance Centre.
9.0 Annual maintenance by the Authorized Assistance
Centre
The following operations are to be programmed annually by the Authorized Assistance
Centre and are necessary to insure that the product remains efficient and guarantee
safe operation.
• Careful cleaning of the combustion chamber;
• Cleaning and inspection of the smoke clearing ducts;
• Checking the seal of the gaskets;
• Cleaning the mechanisms and moving parts (motors and fans);
• Checking the electrical parts and the electronic components.
9.1 Operations to perform every season before the first lighting
• A general cleaning inside and outside;
• A careful cleaning of the exchange tubes;
• A careful cleaning and disincrustation of the crucible and the relative cavity;
• Clean the motors, checking the play and fastenings of the mechanisms;
• Clean the smoke channel (substitute the tube gaskets) and smoke extractor fan ca-
vity;
• Clean silicone tube connected to the pressure switch;
• Clean, inspect and disincrust the lighting resistor cavity, replacing it if necessary;
• Clean/check the synoptic panel;
• Visually inspect the electrical cables, the connections and the electrical power cable;
• Clean the pellet container and verify the play with the screw feeder gear motor;
• Replace the door seals;
• Functional assessment, loading the screw feeder, lighting, 10 minutes of operation
and shut down.
