Normal Operation; Electrical Power Supply Failure; Operation During Transition Periods - LA NORDICA TERMOCAMINO-650 Manuel Utilisateur

cm by 3 cm Picture 12. Cross the four logs and place them on top of the pile of wood at right angles, with the fire lighter (wax impregnated
wood fibre for example) in the middle. The fire can be lit with a match. if you want, you can use thinner pieces of wood. in this case, you will
need a larger quantity. keep the flue gas exhaust valve and combustion air regulator open.
after lighting the fire, leave the combustion air regulator open in the position shown in the picture.
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fine particle emissions.

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.
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.
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 is the following one: see chap. TeCHniCaL desCRipTion. The
appliance works as an intermittent operating appliance.
In the event that the water temperature exceeds the tripping temperature of the safety devices, immediately suspend the
feeding of wood, and make sure that the water temperature and the flame decrease, eliminating the causes of the
overheating (if necessary by closing the air register). If the water system is connected in the thermo-fireplace, the hot water
tap can be opened to speed up the cooling of the 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.

ELECTRICAL POWER sUPPLY FAILURE

in the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these simple
manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.
• Close completely the primary and secondary air registers in order to smother the flame as much as possible.
• Close the smokes register, if existing, to limit further coming of combustive air through possible cracks.

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 thermo-fireplace.
ATTENTION: never light for any reason if the installation is not completely full of water in order to avoid a serious damage of the
whole structure. The installation must always be full of water even when the thermo-fireplace is not used. a possible no use during
winter season must be faced by adding antifreeze substances.
