CLEANINg OUT THE AsHEs

All the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes.
It is suggested to empty periodically the ash drawer and to avoid it fills completely in order not to overheat the grating. Moreover, it is
suggested to leave always 3-4 cm of ash in the hearth.
CAUTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped
with an air-tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the
switching off and complete cooling.

CLEANINg THE FLUE

The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough draught
of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
The device should be completely cleaned at least once a year or every time it is a needed (in case of bad working and low yield). An excessive
deposit of soot can cause problems in the discharge of smokes and fire in the flue.
The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper
who can simultaneously perform an audit of the flue (checking of possible deposits).
During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deflectors from the device in order to ease the fall of
the soot. The deflectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing has been carried
out, place them back in their seats
CAUTION: The lack of the deflectors causes a strong depression, with a too fast combustion, an excessive consumption of
wood with related overheating of the device.

sUMMER sTOP

After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth and
the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work others possible
appliances connected to the same flue.
We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the rope seals,
which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In this case the
seals must be replaced.
In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the hearth.
If you want to keep for long the aesthetic look of the cooker it is important to protect its internal walls in row cast iron with neutral
Vaseline.

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 3 = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
