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 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
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 10).
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.
INSERTO 50V- p30 Crystal: To ease the natural circulation of air (upward movement due to the heating of the same) in the external
enclosure of the stack, it is necessary to remove the underlying semi-blanks (see
CONNECTION AND MAINTENANCE OF VENTILATION
The control unit and the plant must be installed and connected by authorized personnel according to the standards
in force (see chapter GENERAL PRECAUTIONS).
ATTENTION: the control unit and the feeding cable must not be in contact with hot parts.
Our products are equipped with tangential fans suitable to improve the distribution of heat through the ventilation exclusively of the
installation room (see SERIES VENTILATION chapter TECHNICAL DATA SHEET).
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 as shown
hereafter (see chapter SERIES VENTILATION) before the INSERT starts to operate. This operation must be done without electric
energy!!
On our products, it is possible to install OPTIONAL ventilation kits suitable to improve the distribution of heat by ventilation only either
of the installation room or of the adjacent local (see chapter VENTILATION HOOD OR ADJACENT LOCAL). For the connection of
the ventilation kit, please see chapter OPTIONAL VENTILATION KIT.
The Kit is made up of a centrifugal fan, a lighting and adjustment control unit, and a (TM) thermostat that lets the fan start when the
device is properly heated and lets it stop when the fan is partially cold.
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 to the regulations
in force. Correct operation of the command is assured only for the proper motor for which it has been manufactured.
Improper use relieves the manufacturer from each responsibility.
