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
After having checked that the door is completely shut (lowered), unlock the upper latch
the glass, then close the flap and lock the latch before lifting again the door.
