Precautions; Connection To The External Air Intake - MCZ Polar Installation And Use Manual

2.3.

PRECAUTIONS

IMPORTANT!
Installation and assembly of the stove must be
carried out by qualified personnel.
The stove must be installed in a suitable position to allow the normal
operations of opening and ordinary maintenance.
The site must be:
• capable of providing the environmental conditions for operation
• equipped with power supply 230V 50 Hz (EN73-23)
• capable of taking an adequate system for smoke discharge
• provided with external ventilation
• provided with an earth connection complying with CEI 64-8
The stove must be connected to a flue pipe or an internal or
external vertical duct conforming to current standards UNI
7129 - 7131 9615.
The stove must be positioned in such a way that the electrical
plug is accessible.
IMPORTANT!
The stove must be connected to a flue pipe or a
vertical duct which can discharge the fumes at the
highest point of the building.
The fumes are however derived from the combustion
of wood products, and if they come into contact with
or close to walls, they can make dirty marks.
Also take care because the fumes are very hot but
almost invisible, and can cause burns on contact.
The holes for the passage of the smoke pipe and for
the intake of air from outside should be made before
positioning the stove unit.
2.4.

CONNECTION TO THE EXTERNAL AIR INTAKE

It is essential that at least as much air must be able to flow into the
room where the stove is installed as is required for proper combustion
in the appliance and for the ventilation of the room. This can be
effected by means of permanent openings in the walls of the room to
be ventilated, which give onto the outside, or by single or collective
ventilation conduits.
For this purpose, on the external wall near the stove, a hole must be
made with a minimum free cross-section of 100 cm². (equivalent to a
round hole of 12 cm diameter or a square hole 10x10 cm), protected by
a grille on the inside and the outside.
The air intake must also:
• communicate directly with the room where the stove is installed
• be protected by a grille, metal mesh or suitable guard, as long as
this does not reduce the cross-section below the minimum.
•
be positioned in such a way as to be impossible to obstruct
It is not compulsory to connect the air inlet of the
stove directly with the exterior, but an air flow must
be guaranteed of at least 50 m³/h. Refer to current
standards.
