ExTERNAL AIR INTAKE
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 intake must be in a position where it cannot be obstructed.
•
The air intake should communicate with the room in which the device is installed and be protected with a grille.
•
Vents may communicate with adjacent rooms but NOT with garages, kitchens, bathrooms or boiler rooms (FORBIDDEN).
•
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.
•
Minimum dimensions (See chapter TECHNICAL DATA)
VENTILATION HOOD OR ADJACENT LOCAL
Our products are equipped with tangential fans suitable to improve the distribution of heat through the ventilation exclusively of the
installation room (see chapter SERIES VENTILATION).
On our products, it is possible to install OPTIONAL ventilation kits (NO Inserto 50 - NO Inserto 80 High Pressure) suitable to
improve the distribution of heat by ventilation only either of the installation room or of the adjacent local (see chapter OPTIONAL
VENTILATION KIT).
The product can distribute heated air by natural convection or forced convection by means of a centrifugal fan (OPTIONAL); therefore,
during installation, it is necessary to establish the type of ventilation or convection to be adopted.
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
Picture
10).
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
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;
g)
The OPTIONAL ventilation kit has to be installed below the appliance in the rear part (see instructions in chapter OPTIONAL
kit ventilation). As consequence you should arrange a underlying space to collocate it, allowing a proper air flow and the
accessibility for future maintenance.
ELECTRICAL CONNECTION
The installation and the connection of the product has to be carried out by authorized personnel according to the current
regulations (see chapter GENERAL PRECAUTIONS). La NORDICA S.p.A. declines any responsibility for the product that has
been modified without written authorisation as well as for the use of non-original spare parts.
ATTENTION: do NOT place the electric cable nearby hot parts.
CONNECTION: Connect the electric cable to a bipolar switch with a distance of at least 3 mm between the contacts (Power source
230 V~ 50 Hz, the correct connection to the grounding system is necessary).
WARNING: This operation must be carried out without power supply !!
WARNING: The PRODUCT must be connected to the mains with a differential line cut-off switch according to the regulations in force.
Improper use relieves the manufacturer from each responsibility.
