Normal Operation - Nordica STEFANY Forno Bedienungsanleitung

The lever of the mobile grate must be completely inserted.
The openings for air (primary and secondary) must be opened together (you must open the eventual
butterfly valve placed on the pipe of smokes exhaust). When the wood starts burning, you may load other
fuels and adjust the air for combustion according to the instructions on paragraph 10.
Please always be present during this phase.
Never overload the appliance (see the technical table - max. quantity of fuel that can be loaded) .
Too much fuel and too much air for combustion can cause overheating and therefore damage the
stove.

10. NORMAL OPERATION

For safety reasons the door of the appliances with constructive system 1, must be opened only for the
loading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth
must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open
door is allowed under supervision.
IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the
fuel. The hearth door must always remain closed during operation or rest.
The nominal power of the appliance is of kW 9. This power will be reached with a minimum depression in
the chimney of 12 Pascal (=1.2 mm of water column).
With the control located on the front of the appliance (Picture 5 Position A), it is possible to adjust the heat
emission of the same. This is 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.
You should always use the stove with the door closed in order to avoid damages due to overheating
(forge effect).
The inobservance of this rule makes the warranty expire.

Combustion time
The chimney stove is an appliance with intermittent operation.
Besides the adjustment of air for combustion, the intensity of the combustion and consequently the thermal
performance of your appliance is influenced by the stack. A good draught of the stack requires a stricter
adjustment of air for combustion, while a poor draught requires a more precise adjustment of air for
combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the appliance is not properly adjusted or the wood is too wet; if instead the
smoke is grey or black, it signals that the combustion is not complete (it is necessary a greater quantity of
secondary air.
