The nominal power of the appliance (6,5 kW) will be reached with a minimum depression in the chimney of 12 Pa ( =
1,2 mm of water column).
With the registers located on the front of the appliance it is possible to adjust the heat emission of the same. They
have to be opened according to the calorific need. The best combustion (with minimum emissions) is reached when,
by loading the wood, most part of the air for combustion flows through the secondary air register.
Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and too much
air for the combustion may cause overheating and then damage the stove.
The warranty does not cover the damages due to overheating of the equipment.
You should always use the stove with the door closed in order to avoid damages due to overheating (forge effect).
Besides by the adjustment of air for the combustion, the intensity of combustion and then the calorific value of your
stove is affected by the chimney. A good flue of the chimney requires a more reduced adjustment of air for the
combustion, while a poor flue needs more an exact adjustment of air for combustion.
To verify the good combustion of the stove, check if the smoke coming out from the chimney is transparent. If it is
white, it means that the stove is not correctly adjusted or the wood is too wet; if on the contrary the smoke is grey or
black, it means that the combustion is not complete (it is necessary a greater quantity of secondary air).

OPERATION DURING TRANSITION PERIODS
During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it
can happen that the combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently
and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning
(growing up of the flames) and the stabilization of the draught.
Then, check that all openings for the cleaning and the connections to the stack are air-tight.

MAINTENANCE AND CARE
Let check the installation of your stove, the connection to chimney and the ventilation by your chimney sweeper.
For the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive detergents.
IMPORTANT: It is possible to use exclusively spare parts clearly authorized and offered by DAL ZOTTO. In case of
need please apply to your dealer !
THE APPLIANCE CAN NOT BE MODIFIED!
12.1.
CLEANING OF THE FLUE
A correct lighting, the burning of a proper fuel, the loading of the suggested quantity of fuel, the right adjustments of
the secondary air control, the sufficient draught of the chimney and the presence of air for the combustion, are
essential for the good operation of the appliance.
The appliance should be completely cleaned at least once a year or every time it is needed (in case of bad working
and low yield).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 from the appliance the ash drawer
and the smokes pipes. It is possible to clean the space for the collection of smokes from the hearth or through the
smoke exhaust, by using a brush and a vacuum cleaner. Once the cleaning has been completed, the same has
to be positioned back in its seat.
12.2.
CLEANING OF THE GLASS
Thanks to a specific entry of the secondary air the building of deposit on the glass of the door is slowed down in a
remarkable way. However the building of this deposit cannot be avoided with the use of solid fuels such as wet wood,
and this is not to be considered as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold appliance to
avoid the explosion of the same. Do not use cloths, abrasive or chemically aggressive products by cleaning
the hearth glass.
