Distribution Of Heat Through The Ventilation; Ventilation Of The Installation Room; Ventilation Of The Adjacent Local - Nordica INSERTO 70 L Manuel Utilisateur

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:
Appliance categories
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.

DIsTRIBUTION OF HEAT THROUgH THE VENTILATION

During installation, it is necessary to establish the type of ventilation or convection to be adopted.

VENTILATION OF THE INsTALLATION ROOM

Our products are equipped with sERIEs tangential fans suitable to improve the distribution of heat through the ventilation exclusively
of the installation room).

VENTILATION OF THE ADJACENT LOCAL

In addition to the standard equipment , on our products, it is possible to install OPTIONAL ventilation kits suitable to improve the distribution
of heat by ventilation either of the installation room or of the adjacent local (see
The OPTIONAL ventilation kit has to be installed below the appliance in the rear part (see instructions manual CONNECTION AND MAINTENANCE
OF VENTILATION OPTIONAL). As consequence you should arrange a underlying space to collocate it, allowing a proper air flow and the
accessibility for future maintenance.
The covering of each product is equipped with 2 outputs with a diameter of 120 mm (12 cm) for the connection of pipes resistant to heat.
a) Perform the drilling on the walls or on the existing hood to allow the passage and the application of the (fire-resistant) hoses with
related openings.
b) Fasten the pipes by means of clamps to the related collars and openings, after having removed the semi-blanks caps (see
c) Each pipe must not exceed 1.5 m of length for natural ventilation and 4 m for forced ventilation; it must be insulated with insulating
materials to avoid noise and dispersion of heat.
d) The openings have to be positioned at a height not lower than 2 m from the floor to avoid that hot air at output meets people. Please
respect the distance of the convection openings according to the local construction norms;
e) The lengths of the canalization pipes must have the same length to avoid the distribution of differing quantities of air from each
output (see Picture 11).
f ) If the space between the upper part of the insert and the lower profile of the hood is lower than 10 cm, it is necessary to perform a hole
of about 30 x 40 cm on the hood to allow the fastening of the hoses;
