2. INSTALLATION IN ACCORDANCE WITH UNI

10683

2.1. OPERATING AREA

For good operations and good heat distribution, the fireplace stove should be positioned in a place where the air required for combustion can flow (at least 60 m3/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 m3.

Air must enter through permanent apertures on the walls (near the fireplace stove) that open outdoors with a minimum section of 360 cm2.

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 the provisions of current regulations.

 Fireplace stoves may not be installed in

bedrooms, bathrooms and where another heating device is installed without autonomous air flow (fireplace, stove, etc.).

 Placing the fireplace stove in explosive

environments is prohibited.

 The floor of the room where the fireplace stove

is to be installed must be strong enough 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 fireplace

stove at least 5 cm from the walls.

2.2. PRECAUTIONS

The fireplace stove must be installed in a suitable surface that permits routine opening and maintenance operations.

The room must be:

 suitable for room operating conditions  equipped with power supply 230V 50 Hz  equipped with an adequate smoke exhaust system  equipped with outdoor ventilation  provided with an earth connection complying with CEI

INSTALLATION AND USE MANUAL

Chapter 2

page 8

Theoretical notions for installation

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

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 cm2 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.

2.4. CONNECTION TO THE FLUE PIPE

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 connection must have a maximum inclination of 45° to

prevent excessive build up of condensation produced in the initial start-up stages of the closed fireplace and/ or excessive adhesion of creosote. This also prevents smoke evacuation from slowing 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 elements of the connection must be perfectly sealed.  The connection to the flue pipe must be neither too long (to

prevent obstructions) nor too short (to prevent 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.

2.5. FLUE PIPE

The flue pipe is a fundamental element in discharging smoke and therefore must have the following requisites:

 be waterproof and thermally insulated.  be made of suitable heat-proof materials that are resistant to

the effects of combustion products and any possible 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

product and marked EC (EN1856-1, EN1443).

 must be suitably sized to accommodate the draught/smoke

disposal requirements necessary for the correct functioning of the product (EN13384-1).

 have an internal section which is preferably circular.  be cleaned if pre-existing and has operated beforehand.

The flue pipe is of primary importance for the correct functioning and safety of your fireplace stove.

2.5.1. Examples of flue pipes

Square or rectangular section flue pipes 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 sections/lengths of the flue pipe shown in the technical data table are guidelines for correct installation. Any alternative configurations must be suitably sized in accordance with EN13384-1.

The smoke duct should be equipped with a solid material collection 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.

AISI 316 stainless steel flue pipe with dual chamber insulated with ceramic wool or equivalent resistant to 400°C.

EXCELLENT

Flue pipe in refractory brick with insulated double wall and external coat of cement mix lightened with honeycomb material such as clay.

GOOD

Traditional square section clay flue pipe with insulating hollow inserts.

GOOD

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.

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.

An industrial cowl, with prefabricated sections fitting together, allows optimal disposal of the flue gases.

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.
