NORMAL OPERATION
After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses and
deformations. You should always use the product with the door closed in order to avoid damages due to overheating (forge effect).
The inobservance of this rule makes the warranty expire.
With the registers located on the front of the device, 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. Too much fuel and too much air for the combustion may cause overheating and then damage
the product.
You should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect).
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 12 Pa (=1.2 mm of column of
water) is the following one: see chap. TECHNICAL DESCRIPTION. The appliance works as an intermittent operating appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of the
device 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 device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).
WARNINg: When fuel is added onto the embers in the absence of a flame, a considerable amount of fumes may develop. Should
this happen, an explosive mixture of gas and air may form, and in extreme cases an explosion may occur. For safety reasons it is
advisable to perform a new lighting procedure with the use of small strips.
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. In case of doubt, do not operate the
product.
MAINTENANCE AND CARE
Check the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimney sweeper.
Let your chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the aeration.
IMPORTANT: The maintenance must be carried out only and exclusively with cold device .You should only use spare parts
approved and supplied by La NORDICA s.p.A. . Please contact your specialized retailer if you require spare parts.
YOU MUsT NOT MAkE ANY CHANgEs TO THE DEVICE!!!
gLAss CLEANINg
Thanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efficacy. Nevertheless this can
never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion
of the same. For the cleaning, it is possible to use specific products or a wet newspaper paper ball passed in the ash to rub it.
Do not use cloths, abrasive or chemically aggressive products by cleaning the hearth glass.
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 and for the
cleaning of the glass.
BREAk OF gLAssEs: given that the glass-ceramic glasses resist up to a heat shock of 750°C, they are not subject to thermal
shocks. Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, their
replacement is not included in the warranty.
