2. Theoretical notions for installation

The instructions contained in this chapter explicitly refer to the regulations of the Italian installation Standard UNI 10683. In any case, always comply with the regulations in force in the country of installation.

2.1. Pellets

Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders. The market offers different types of pellets with characteristics that vary according to the wood mixtures used. The most common diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 3 and 40 mm. A good quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water content that accounts for 5 to 8% of its weight. Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner combustion than that of fossil fuels. Good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg bags, therefore, storing them is very convenient. Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.

The main quality certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to ISO 17225-2. (formerly EN 14961). These certifications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular, guarantee the following characteristics:

 calorific value: 4.6 ÷ 5.3 kWh/kg.  Moisture content: ≤ 10% of the weight.  Percentage of ash: max 1.2% of the weight (A1 less than

0.7%).

 Diameter: 6±1/8±1 mm.  Length: 3÷40 mm.  Content: 100% untreated wood without the addition of binding

substances (max 5% bark).

 Packaging: in sacks made from ecologically compatible or

biologically decomposing material.

IMPORTANT! Installation and assembly of the stove must be

carried out by qualified personnel.

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.

2.2. PRECAUTIONS FOR INSTALLATION

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  capable of taking an adequate system for smoke discharge  provided with external ventilation  provided with an earth connection complying with CEI

The stove must be connected to a flue pipe or an internal or external vertical duct conforming to EN 1856-1-2 to suit the appliance and types of fuels to be burnt – refer to detailed guidance in sections 2, 3 and 4 in ADJ (ONLY FOR UK).

The stove must be positioned in such a way that the electrical plug is accessible.

It is not permissible to install the stove in bedrooms, bathrooms, or in a room where another heating appliance is installed (fireplace, stove etc.) which does not have its own independent air intake.

Locating the stove in a room with an explosive atmosphere is prohibited. The floor of the room where the stove is to be installed must be strong enough to take its weight.

If the flooring is made of wood, provide a floor protection surface in compliance with current national standards.

Example of pellet stove installation

2.3. OPERATING AREA

For proper functioning and a good temperature distribution, the stove should be positioned in a location where it is able to take in the air necessary for combustion of the pellets (about 40 m3/h must be available), as laid down in the standard governing the installation and in accordance with local national standards.

The volume of the room must not be less than 30 m3. The air must come in through permanent openings made in walls (in

proximity to the stove) which give onto the outside, with a minimum cross-section area of 100 cm2.

These openings must be made in such a way that it is not possible for them to be obstructed in any way.

Alternatively, the air can be taken from rooms adjacent to the one which needs ventilating, as long as they are provided with an air intake from the outside, and are not used as bedrooms or bathrooms, and provided there is no fire risk such as there is for example in garages, woodsheds, and storerooms, with particular reference to what is laid down in current standards.

If walls are flammable, maintain a minimum distance of 10cm at the rear (A), 10cm at the side (B) and 100 cm at the front.

If the room contains objects which are believed to be particularly delicate, such as drapes, sofas and other furniture, their distance from the stove should be considerably increased.

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 ducts.

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

Pipes and unions with suitable gaskets must always be used, to guarantee a hermetic seal.

All sections of the smoke duct must be inspectable and removable to enable periodic internal cleaning. Tee connectors with inspection caps should be used.

ONLY FOR UK

Example of pellet stove installation

 Be protected by a grille, metal mesh or suitable guard, as long as

this does not reduce the area below the minimum.

 be positioned in such a way as to be impossible to obstruct

2.5. CONNECTION OF SMOKE DISCHARGE PIPE

We recommend the use 100mm single wall connecting flue pipe. All exterior flue or flue used internaly above 1.8m should be twin wall

insulated pipe installed in accordance with ADJ reference page 23 section 1.31 and 1.32 and 1.33 & Hetas regulations.

The combustion chamber works in low pressure. The smoke duct for the discharge of fumes will also be under low pressure when connected to an efficient flue pipe as directed.

Position the stove bearing in mind all the instructions and considerations above.

2.6. CONNECTION TO THE FLUE PIPE

. In the event of larger dimensions, or of the flue pipe being in poor condition (for example cracks, poor insulation, etc.), it is advisable to fit a stainless steel pipe of suitable diameter inside the flue pipe throughout its length, right up to the top. At the bottom of the flue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the flue pipe, using pipes and connectors as recommended by us. You must ensure that a windproof cowl should be fitted which complies with the standards in force.

2.7. CONNECTION TO AN EXTERNAL FLUE WITH INSULATED OR DOUBLE-WALL PIPE

The external fluepipe must have internal dimensions of a minimum of 150mm, and maximum 180mm.

Check with suitable instruments that there is a minimum draught of 5 Pa. on low fire and 10pa on high fire. The flue must always run under negative pressure and a cold flue pull of – 2>3 pascals must be secured.

The only type of pipe which is permissible is insulated (double-walled) stainless steel, smooth on the inside, fixed to the wall. At the bottom of the flue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the flue pipe, using pipes and connectors as recommended by us. You must ensure that a windproof cowl should be fitted which complies with the standards in force.

2.8. OPERATING PROBLEMS CAUSED BY DRAUGHT DEFECTS IN THE FLUE

Of all the weather and geographical conditions which affect the operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to sunlight, direction of facing), the wind is unquestionably the most decisive. In fact, along with thermal depression caused by the difference in temperature inside and outside of the chimney, there is another type of depression or over-pressure: dynamic pressure caused by the wind. An updraft always increases depression and hence draught. A crosswind increases depression provided the cowl has been installed properly. A downdraft always decreases depression, at times inverting it.

Besides the direction and force of the wind, the position of the flue and the cowl with respect to the roof of the building and the surrounding landscape is important.

The wind also influences the operation of the chimney indirectly by creating high-pressure and low-pressure zones, not only outside the building but inside as well. In rooms directly exposed to the wind (2), an indoor high-pressure area can be created which can augment the draught in stoves and fireplaces, but it can be counteracted by the external high pressure if the cowl is situated on the side exposed to the wind (1). On the other hand, in the rooms on the opposite side from the direction of the wind (3), a dynamic depression can be created which competes with the natural thermal depression developed by the chimney, but this can be compensated for (sometimes) by locating the flue on the opposite side from the direction of the wind (4).

IMPORTANT!

The connection of the stove to the plumbing system must be carried out ONLY by specialized personnel who are capable of carrying out installation properly, in compliance with current standards in the country of installation.

It is important that ONLY qualified engineers are used to fit and commission the appliance in ALL cases. The installing engineer MUST hold a QCF recognised biomass qualification. Any company using sub-contractors MUST ensure they also hold the relevant qualifications.

If installation of the stove will involve interaction with another, pre-existing system complete with heating equipment (gas boiler, methane boiler, fuel oil boiler, etc.), it is even more advisable to call in qualified personnel, who subsequently will be responsible for conformity of the system with current applicable law.

MCZ will not be held responsible for damage to persons or things in the event of failed or incorrect operation if the aforementioned warnings are not complied with.

3.2. PREPARATION AND UNPACK ING

STAR and EGO stoves are delivered with two different packagings:

 The EGO and MUSA stove has one packaging

o It contains the stove and the steel sides with the

profiles (Fig.1)

 The STAR stove has two packagings

o One contains the stove and the profile for the ceramic

or the soapstone

o One contains the ceramic (fig.2). In this case there will

be a single packaging for the structure (the cardboard with the ceramics will be placed above the packaging with the structure)

o or Soapstone (fig.3) (in this case there are two

packagings structure + soapstone pallet)

 SUITE and CLUB stoves are delivered in two packages placed

on top of each other:

o the first contains the stove o The second contains the ceramic cladding. (Fig. 2)

EGO/STAR and MUSA stoves

Open the packaging, remove the four screws that secure the base of the stove to the pallet, two to the right and two to the left (see figure

4), and position the stove in the selected place, ensuring that it is complies with the above instructions.

If the smoke outlet of the stove is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

Figure 5 - Removing the packaging screws

(in figure Suite stove)

SUITE and CLUB stoves

Open the packaging, remove the two brackets that lock the stove to the pallet (one on the right and one on the left side-fig.5)

The stove body or unit must always be kept in a vertical position when moved, and moved only using carts. Special care must be used to protect the door and the glass from impacts that would damage them.

Moving the product must always be done with care. If possible, unpack the stove in the area where it is going to be installed.

The materials which make up the packaging are not toxic or harmful, so no special procedures for disposal by required.

Their storage, disposal or possible recycling are therefore the responsibility of the final user, in compliance with current legislation on the subject.

Do not store the stove unit or its cladding without their packaging.

Position the stove without its cladding and connect it to the flue pipe. Use the four adjustable feet (J) to get the stove correctly levelled so that the smoke outlet (S) is lined up with the connecting pipe (H). Once the operations for connection are complete, assemble the cladding (ceramics or steel sides).

If the stove needs to be connected to a discharge pipe which goes through the rear wall (to connect up with the flue), take the greatest care to make sure that the joint is not stressed.

IMPORTANT IT IS STRONGLY RECOMMENDED TO FLUSH THE

ENTIRE SYSTEM BEFORE CONNECTING IT IN ORDER TO GET RID OF RESIDUES AND DEPOSITS.

Upstream from the stove, always install valves so as to disconnect it from the plumbing system should it be necessary to move it, or when it requires routine and/or special maintenance.

Connect the stove using flexible hoses so that the stove is not too strictly connected to the system, and to allow slight movements.

The pressure discharge valve (C) is always connected to a water drain pipe. The pipe must be adequate to support the water's high temperature and pressure.

To ensure the valve vents correctly, it is advisable to loosen the grey cap one turn and to keep the red cap blocked

The filling pressure of the system WHEN COLD must be

1 bar.

During operation, if the system pressure drops (due to evaporation of dissolved gases in the water) to values lower than the minimum indicated above, the user must use the filling tap to bring the pressure back up to its normal pressure.

For proper operation of the stove WHEN HOT, the pressure in the boiler must be1.5 bar.

3.4.3. Water characteristics

The characteristics of the water used to fill the system are very important to prevent the build-up of mineral salts and the formation of incrustations along the pipes, in the boiler and in the heat exchangers.

Therefore, please GET YOUR PLUMBER'S ADVICE CONCERNING:

If you have very extensive systems, with a large amount of water, or which require frequent refilling, the installation of water softening systems.

To ensure that the plate heat exchanger continues to operate correctly over time, it is important that you know the water hardness of your system to prevent deposits from forming.

If the water in your home is very hard, you are advised to install a softening system upstream (see chapter 3.4.3)

You are advised to maintain the plate heat exchanger annually to eliminate calcium sediments and mineral salts or to replace heating plates with new ones. MCZ supplies these replacement parts.

3.5. KIT FOR DOMESTIC HOT WATER PRODUCTION (Optional) Only for Suite/Club/Musa stoves

SUITE – CLUB and MUSA stoves can also be equipped with a full kit for the production of domestic hot water. This kit comprises:

 A plate heat exchanger  A three-way diverter valve  Water flow switch  Pipes and unions for connection

The kit is designed to heat domestic water directly from the home water supply system. MCZ supplies the kit ready-assembled. When the tap is turned on and hot water is needed, the internal water flow switch will send a signal to the diverter valve to channel the hot water from the boiler (where it is stored) to the plate heat exchanger. The temperature of the domestic water depends a great deal on the temperature of the water inside the heating system. This can be calculated to a good degree of accuracy by taking 10°-15°C away from the value shown on the control panel of the stove (which is the temperature of the water in the boiler).

If hot domestic water is needed while the stove is ‘Off’ or in ‘off ECOSTOP’ mode, the stove will automatically and immediately begin the

start-up process to heat the water inside the boiler, followed by the domestic hot water.
