2. NOTIONS FOR INSTALLATION ACCORDING TO UNI 10683
2.1. OPERATING AREA
For good operations and good heat distribution, the stove should be
positioned in a place where the air required for combustion can flow (at
least 60 m
3
/h must be available) according to installation standards and
current regulations in the country of installation.
The room volume must not be less than 60 m
3
.
Air must enter through permanent apertures on the walls (near the
stove) that open outdoors with a minimum section of 150 cm
2
.
These apertures (air vents) must be made so as not to be obstructed in
any way.
Air can also be taken from adjacent rooms as long as these are
equipped with outdoor air vents and not bedrooms or bathrooms or
rooms where fire hazards do not exist such as garages, wood sheds,
flammable material warehouses, strictly observing that stated in current
regulations.
•Stoves may not be installed in bedrooms,
bathrooms and where another heating device is
installed without autonomous air flow (chimney,
stove, etc.).
•Placing the stove in explosive environments is
prohibited.
•The floor of the room where the stove is installed
must be adequately dimensions to support its
weight.
•In the event of wood floors, install a protective
covering in accordance with current regulations
in the country of installation.
•If walls are not flammable, install the stove at
least 5 cm. from the walls.
•The stove could cause overheating and damages
to plaster (yellowing, cracking, etc.) if
excessively close to the wall.
2.2. PRECAUTIONS
The stove must be installed in a suitable surface that permits routine
opening and maintenance operations.
The room must be:
•set for room operating conditions
•equipped with an adequate smoke exhaust system
•equipped with outdoor ventilation

INSTALLATION AND USE MANUAL Chapter 2
page 8
Theoretic notions for installation Technical service - MCZ S.p.A. all rights reserved - Reproduction prohibited
IMPORTANT!
•The stove must be installed and assembled by
qualified personnel.
•The stove must be connected to a chimney flue or
other vertical smoke stack that can discharge
smoke at the highest point of the house.
•The stove must be connected to the internal or
external chimney flue or smoke stack, according
to current regulations.
•Smoke is generated from burning wood and,
therefore, may dirty adjacent or nearby walls.
•Before installing the stove, drill a hole for the
external air outlet.
2.3. EXTERNAL AIR OUTLET
The room where the stove is installed must have at least as much air as
requested by normal device combustions and by room ventilation. They
may occur 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 150 cm² free section near
the stove (15 cm diameter or a 10x15cm rectangle), protected by an
indoor and outdoor grill.
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
•in the event of conduits, up to 3.5 ml, increase the section by
about 5% while increased by 15% for larger measurements.
Remember that the ventilation grill 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 stove is not
mandatory but the abovementioned section must guarantee
about 50 m³/h of air. See regulation UNI10683 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.

2.4. CHIMNEY FLUE CONNECTIONS
Connections to the chimney flue is important and should be conducted
with care and attention. Stoves have top or rear smoke exhausts.
The smoke exhaust pipe must be assembled to guarantee seals during
product operations in depression and avoid the formation and transport
of condensation to the stove.
Any manual draft adjustment devices inserted in the pipe must not
hermetically close the internal conduit section. These gates must be
equipped with a mechanism that prevents the full rotation of the valve
in the closed position. The minimum safety opening surface must be
3% of the passage section and not less than 10 cm². If the smoke
conduit has a horizontal segment, this must have a minimum upward
gradient of 3-5% (3-5 cm per meter).
The tilted horizontal part must not be longer than 2 ml.
The use of flexible and cement fibre pipes is
prohibited. The smoke stack must not cross rooms
where the installation of combustion devices is
prohibited. The use of pipes in counter-slope is
prohibited.
2.5. CHIMNEY FLUE
The chimney flue is a fundamental element in discharging smoke and
therefore must have the following requisites:
•It must be waterproof and thermally insulated.
•It must be made with heat resistant materials, resistant to
combustion products and any condensation.
•It must have a vertical slope with axis deviations not over 45°
and without narrowing.
•It must meet the requisites indicated in the technical table for
the internal chimney section and height.
•It must preferably have a circular interior section.
•If pre-existent and previously operative, it must be clean.
The chimney flue is of primary importance for the
correct operations and safety of your stove.

chimney flue with a chamber and sealed
door for solid combustion product collection

2.5.1. Examples of chimney flues
AISI 304 stainless steel chimney
flue with dual chamber insulated
with ceramic wool or equivalent
resistant to 400°C.
EXCELLENT
Refractory chimney flue with
dual insulated chamber and
external concrete sleeve and
lightweight clay type
honeycomb material. GOOD
Traditional square section clay
chimney flue with insulating
hollow inserts.
AVERAGE
Avoid chimney flues with
internal rectangular sections
whose larger side is double the
smaller such as 20x40 or
15x30.
POOR
Square or rectangular section chimney flues must have rounded internal
corners with radius not less than 20mm. For the rectangular section,
the ratio between internal dimensions must be ≤1.5.
The recommended section for a chimney flue according to its length is
listed in the table below:
Height (m) Section (cm²)
Up to 5 mt (20x30 cm or ∅ 22 cm)
From 5 to 7 mt (20x20 cm or ∅ 20 cm)
Over 7 mt (18x18 cm or ∅ 18 cm)
N.B. Too small or too large a section reduces draught and insulation.
For special sections or section or travel variations, functional smoke
exhaust inspections must be conducted as per UNI 9615.
The smoke conduit should be equipped with a solid material collection
chamber at the mouth of the smoke conduit to be easily opened with an
airtight door.
IMPORTANT!
In the event of doubt on your chimney flue
operations or that its dimensions are different from
those recommended, we highly suggest an
authorised MCZ technician inspect and measure
chimney flue performance (micro-gauge
measurements)
MCZ s.p.a. is not liable for poor stove operations if
attributable to the use of a poorly dimensioned or
non conform installation of the chimney flue.
