Ventilation And Aeration Of The Installation Premises; Allowed / Not Allowed Fuels - Nordica ROSA 4.0 Manuel Utilisateur

VENTILATION AND AERATION OF THE INsTALLATION PREMIsEs

As the product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a sufficient quantity of air is
introduced. If windows and doors are airtight (e.g. built according to energy saving criteria), it is possible that the fresh air intake is no longer
guaranteed and this jeopardises the draught of the appliance and your health and safety.
IMPORTANT: For a better comfort and corresponding oxygenation of environment, the combustion air can be directly withdrawn at the
outside through a junction which is to be connected with a flexible pipe. The connection pipe (not furnished) must be flat with a minimum
Picture 9, a maximum length of 3 m and with no more than 3 bends. If there is a direct connection with the outside it must be
diameter of
endowed with a special windbreak.
There MANDATORY be sufficient quantity of air for combustion and re-oxygenation of the room to ensure the device will work properly.
There should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even when the doors
and windows are closed.
The air inlets must meet the following requirements:
• they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
• they must be made so as to make the maintenance operations possible;
• positioned so that they cannot be obstructed;
• Any extractor hoods in the room where the device is installed must not operate at the same time as this could cause smoke to enter the
room, even with the fireplace's door closed.
The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and ventilation),
as long as the flow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a fire hazard, bathroom, bedroom
or common room of the building.
Ventilation is deemed sufficient when the room is equipped with air inlets according to the table:

Fireplaces
Stoves
Cookers
Installation in premises with fire hazards is forbidden. Installation in residential premises in which, in any case, the depression
measured during installation between the internal and external environment is greater than 4 Pa - reference for Italy according to
standard UNI10683.
All national, regional, provincial and municipal laws and standards in force in the country where the appliance is installed must be complied
with.

ALLOWED / NOT ALLOWED FUELs

Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood
should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.
Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device,
since these have a very high calorific value.
The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to burn
less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content involves
the disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack causing
a remarkable deposit of soot with following possible risk of fire of the same.
Fresh wood contains about 60% of H
It is necessary to place this wood in a dry and ventilated place (for example under a roofing) for at least two years before using it.
Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood or wood treated with
paints, plastic materials; in this case, the warranty on the device becomes void.
Paper and cardboard must be used only to light the fire.
The combustion of waste is FORBIDDEN and would even damage the appliance and the flue, causing health damages and claims
by the neighborhood owing to the bad smell.
The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the night is not
possible.
