draught of the chimney-ue 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.

13.7. CLEANING OUT THE ASHES

All the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes Picture 8 at page 44.

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).

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 11 at page 45 ).

CAUTION: The lack of the deectors causes a strong depression, with a too fast combustion, an excessive consumption of wood

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, see Picture 11 at page 45).

CAUTION: use exclusively the grease supplied by La NORDICA.

14. 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
