Theoretical notions for installation Technical service – MCZ GROUP S.p.A. all rights reserved - Reproduction prohibited
INSTALLATION AND USE MANUAL
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. CONNECTION TO THE EXTERNAL AIR INTAKE
Chapter 2
page
10
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.
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.
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.

INSTALLATION AND USE MANUAL
2.4. CONNECTION TO THE FLUE PIPE
Chapter 2
page
11
The connection to the flue pipe is a very important element. The
connection must be made with a great deal of care; in the event of
erroneous or anomalous construction, it is extremely difficult to remedy
without damaging the hood liner. In addition, the connection is made in
a part of the stove where temperatures are very high, and for this
reason it is important to use materials that are capable of resisting heat
and also the acidity of the fumes produced by combustion.
Before beginning work, please note the following:
The connecting pipe must have a maximum slope of 45
degrees. This is to avoid excessive deposit of condensation
produced in the initial phases of lighting the fireplace stove,
and/or the excessive accumulation of creosote. It also keeps
the release of smoke from being slowed down.
The unions must be made of metal and suitable for the
specific operating conditions of the product and marked
EC (EN1856-2). The use of flexible and extending metal
pipes is not permitted.
The components making up the connecting pipe must be
perfectly sealed.
The joint to the flue pipe must not be too long (to avoid
obstructions), nor too short (to avoid smoke leakage).
If metal connecting pipes are used, they must be
insulated with suitable material such as ceramic fibre
matting, to avoid deterioration of the masonry and of
the decorative hood liner.
IMPORTANT!
Any increase in the section of the connecting pipe
must start immediately above the hood of the
fireplace and not along the flue pipe section.

2.4.1. Smoke valve (optional)
30°
In case of excessive draught in the flue chimney, combustion may
become unbalanced and consequently less efficient. In this case, in
order to improve combustion efficiency, it is advisable to install the
smoke valve (optional) directly at the output of the fireplace stove. If
you wish to position the control knob (B in the figure) at the front of
the product, it is necessary to place a 25 cm extension of the smoke
duct between the fireplace stove and the valve.
2.5. FLUE PIPE
The flue pipe 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.
have a vertical arrangement with deviations from the axis of
no more than 45° and without kinks.
must be suitable for the specific operating conditions of the

chamber at the mouth of the smoke duct 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. shall not be held liable for poor operation
of the fireplace stove that is due to a flue pipe of
improper size or installation that does not comply
with provided requirements.

Avoid flue pipes with internal
rectangular sections whose
larger side is double the smaller
such as 20x40 or 15x30.

2.6. COWL
If underestimated, it is a severe impediment to correct "chimney
system" operations.
Flue pipe draught also depends on its cowl.
Therefore, if hand made, its four exhaust sections must correspond to
more than twice the internal section of the flue pipe.
Having to exceed the peak of the roof, the cowl will be
exposed to wind, therefore an industrial type is recommended.
An industrial cowl,
with prefabricated
sections fitting
together, allows
optimal disposal of
the flue gases.
The cowl must meet the following requisites:
It must have an internal section equal to that of the chimney.
It must have a useful output section not less that double that
of the internal section of the flue pipe.
It must be built to prevent rain, snow and any foreign objects
from getting into the flue pipe.
They must be installed to guarantee adequate smoke
dispersion and out of the reflux area where negative pressure
forms.
For paired flue pipes, the cowl for solid combustion
and the one for the upper floor must be at least 50cm
higher than the other to avoid pressure transfers
between paired flues.
The cowl must not have obstacles within 10 m such as
walls, roof slopes and trees. Otherwise, raise it at least
1 m over the obstacle and, in the event of other
nearby cowls, keep them at least 2 m away. In any
case, the cowl must exceed the peak of the roof by at
least 1m.
A traditional
handmade cowl.
The right exhaust
section must be at
least twice the
internal section of
the flue pipe, 2.5
times is ideal.
