IMPORTANT!
• The fireplace stove must be installed and
assembled by qualified personnel.
• The fireplace stove must be connected to a flue
pipe or other vertical smoke stack that can
discharge smoke at the highest point of the
house.
• The fireplace stove must be connected to a flue
pipe or an internal or external vertical duct
conforming to current standards UNI 7129 -
7131 9615.
• Smoke is generated from burning wood and,
therefore, may dirty adjacent or nearby walls.
• Before positioning the fireplace stove, you must
make a hole for the intake of external air.
2.3. EXTERNAL AIR OUTLET
The room where the stove is installed must have at least as much air as
requested by normal combustion of the equipment and by room
ventilation. This may take place through permanent apertures in the
room walls that lead directly outdoors or ventilated rooms according to
UNI 10683 REV.
For this purpose, drill a hole with minimum 360 cm² free section near
the fireplace stove (22 cm diameter or a 20x18cm rectangle), protected
by an indoor and outdoor grille.
The air intake must also:
•
directly communicate with the installation room
• be protected by a grill, made of metallic anti-insect mesh or a
suitable protection as long as it does not reduce the minimum
section.
• be installed so as to avoid obstruction
• for ducts, up to 3.5 linear metres, increase the section by about
5% while increased by 15% for larger measurements.
Remember that the ventilation grills always have a cm 2
useful section on one side. When selecting the grill and hole
dimension, make sure the useful grill section is greater than
or equal to the section required by MCZ for product
operations.
Connecting the air outlet directly to the fireplace stove is not
mandatory but the above mentioned section must guarantee
about 50 m³/h of air. See standard UNI 10683 REV.
IMPORTANT!
Air flow may also be obtained from a room adjacent
to the installation room as long as this flow is free
through permanent apertures that directly
communicate with the outdoors; avoid air outlets
connecting with heating units, garages, kitchens or
bathrooms.
