10.4. CLEANING THE FIREPLACE
During cleaning remove the top cap of the fireplace which is located on the exhaust fumes pos. B
the help of a hammer as indicated in to the picture) and the top lock steel plate of the fireplace pos. E by turning and pulling it down.
ATTENTION: when you remove the cap and the top lock steel plate of the fireplace, the dirtiness that is inside the chamber of exhaust
fumes falls down, therefore avoid to dirty the inside of the fireplace.
When the cleaning is completed: - put the top cap of the fireplace into its place (B). You have to support the cap to the wall above the
fireplace by passing it through the corresponding slots (C) and then, with a rotary movement of the hand, send the screws at the machined
seats into the wall (D) and leave the cap as support on the upper wall; - put into its place the top lock steel plate of the fireplace as indicated

pos. E.
ATTENTION: The absence of the cap (B) and the top lock steel plate of the fireplace (E) causes a strong depression, leading to
excessively fast combustion and excessive wood consumption, with consequent overheating of the appliance, forge effect,
and decreases the heat discharge of the boiler.
10.5. MAINTENANCE ON THE WATER SYSTEM
Excessive incrustation deposits on the inner walls of the hearth considerably reduce the efficiency of heat exchange; therefore, remove
these deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-fireplace and
the boiler.
With the system switched off, once a year carry out the following checks:
•
Check the operation and efficiency 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 filling pipe and the safety pipe.
•
Make sure that the system is filled and under pressure, checking the water level in the expansion tank; also check that it is working
properly and check the efficiency of the safety pipe.
10.6. 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 difficult 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 calorific value necessary for a properly insulated room is 30 kcal/h per m
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
Let's suppose one wishes to heat a room of 150 m
x 38 W/m
= 5700 W or 5,7 kW. As main heating, a 8 kW device is therefore sufficient.
