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 (see
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.
the OptIOnal ventilation kit has to be installed below the appliance in the rear part (see instructions manual cOnnectIOn and maIntenance

the covering of each product is equipped with 2 outputs with a diameter of 150 mm (15 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
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;
connection and maintenance of ventilation
the control unit and the plant must be installed and connected by authorized personnel according

the power cable has to be replaced by authorised personnel only (entItled by la nOrdIca): authorised
dealers and/or fitter.
Our products are equipped with tangential fans suitable to improve the distribution of heat (see chapter dIstrIbutIOn Of heat thrOugh
the ventIlatIOn).
the lighting and the adjustment is carried out through the proper standard supplied control unit that has to be installed far from any direct
heat source.
the selection of the kind of insert to be connected is in the control unit and has to be done by moving the small bridge 7 (see chapter serIes
ventIlatIOn).
this operation must be done without electric energy!!
connection: connect the power supply cable of the control unit to a bipolar switch respecting at least a 3 mm distance between the
contacts (power supply 230 v~ 50 hz, it is necessary to provide for the correct connection to the grounding plant).
this operation must be done without electric energy!!
warning: the cOmmand must be cOnnected tO the maIns wIth a dIfferentIal lIne cut-Off swItch accOrdIng
