CLEANINg OF THE HEARTH gRATE

IMPORTANT: if for whatever reason the grill is removed from the furnace, take care to reassemble it with the wider part of the slit facing
Picture 8). This is to aid furnace cleaning.

CAsT IRON RADIANT-PLATE AND RINgs

IMPORTANT: to avoid rust DO NOT forget pots or pans on the cold Radiant-plate. This would create rust rings, unpleasant to see
and difficult to remove.
The cast iron Radiant-plate and the cast iron rings needs to be periodically cleaned by using sandpaper (grain 150) without
touching the enamelled parts.

CLEANINg OF THE COLLECTION CAsINg THROUgH THE HEAT ACCUMULATOR

The smokes collection casing can be cleaned either through the heat ACCUMULATOR (remove the horizontal sheet metal which is the base
of the heat ACCUMULATOR See
To this purpose remove the circles of the Radiant-plate and disassemble the smokes pipe from the exhaust small trunk. Cleaning can be made
with a brush and a vacuum cleaner.
IMPORTANT: please verify that the deflectors are set as indicated in the Picture.
Pay ATTENTION that after cleaning all dismounted parts are reinstalled hermetically.

ROUTINE MAINTENANCE PERFORMED BY QUALIFIED TECHNICIANs

Routine maintenance must be performed at least once a year.
Using wood as solid fuel, the generator requires annual routine maintenance, which must be performed by a qualified technician, using
only original spare parts.
Failure to comply can jeopardise the safety of the appliance and make the warranty null and void.
Respecting the frequencies of cleaning reserved for the user described in the use and maintenance manual, the generator is guaranteed
correct combustion over time, preventing any anomalies and/or malfunctioning that could require more interventions of the technician.
Requests for routine maintenance are not contemplated in the product warranty.

gAskETs

The gaskets guarantee the tightness of the stove and its consequent good functioning.
They must be controlled periodically. They must be replaced immediately if they are worn or damaged.
These operations must be carried out by a qualified technician.

CONNECTION TO THE FLUE

Vacuum and clean the pipe that leads to the flue yearly or any time that it is necessary. If there are horizontal tracts, the residue must be
removed before it can prevent the passage of the fumes.

CALCULATION OF THE THERMAL POWER

There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m
external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m
Let's suppose one wishes to heat a room of 150 m
W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
