air-tight cover. The container has to be placed on a re-resistant oor, far from ammable materials up to the switching off
and complete cooling.
10.3. CLEANING THE FLUE
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-ue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
The device should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield). An
excessive deposit of soot can cause problems in the discharge of smokes and re in the ue.
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 ue (checking of possible deposits).
Excessive incrustation deposits on the inner walls of the hearth considerably reduce the efciency of heat exchange; therefore, remove
these deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-replace and
the boiler.
During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deectors from the device in order to ease the
fall of the soot. The deectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing has
been carried out, place them back in their seats (Picture 10 at page 50).
CAUTION: The lack of the deectors causes a strong depression, with a too fast combustion, an excessive consumption of wood
with related overheating of the device.
10.4. MAINTENANCE ON THE WATER SYSTEM
Excessive incrustation deposits on the inner walls of the hearth considerably reduce the efciency of heat exchange; therefore, remove
these deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-replace and
the boiler.
With the system switched off, once a year carry out the following checks:
Check the operation and efciency of the blowdown and safety valves. If they are defective, contact your authorised installer. IT IS
STRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE SAFETY DEVICES.
Check the thermal insulation of the lling pipe and the safety pipe.
Make sure that the system is lled and under pressure, checking the water level in the expansion tank; also check that it is working
properly and check the efciency of the safety pipe.
10.5. MAINTENANCE OF THE EXTENSIBLE GUIDES
To work silently, as well as in a reliable and robust way, the doors are fastened to the extensible ball guides. By using the device continuously,
the lubricant of the guides tends to run out progressively in time making their sliding more difcult and noisy. For this reason, together
with each device a high temperature grease is supplied in order to make the lubrication of the guides possible for the user, in case it
becomes necessary (excessive noise or reduction of smoothness). After having completely lifted the door of the stack, using a syringe,
apply internally on the track on a visible point, as high as possible, two grease balls (corresponding to 0.5 ml of the graduated scale of the
syringe). Pay attention not to exceed the suggested quantity. Repeat the same operation on the other track and lift and lower the door many
times so that the grease distributes on all balls. CAUTION: use exclusively the grease supplied by La NORDICA.
11. CALCULATION OF THE THERMAL POWER
There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the caloric value necessary for a properly insulated room is 30 kcal/h per m
3
(for
an external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 38 W/m
3
.
Let’s suppose one wishes to heat a room of 150 m
3
(10 x 6 x 2.5 m) in an insulated apartment. In this case, it is necessary to have 150 m
3
x 38 W/m
3
= 5700 W or 5,7 kW. As main heating, a 8 kW device is therefore sufcient.
