2. THEORETICAL NOTIONS ON INSTALLATION

2.1. PELLETS

Wood pellets are manufactured by hot-extruding compressed sawdust

which is produced during the working of natural dried unpainted wood.

The compactness of the material comes from the lignin which is

contained in the wood itself, and allows the production of pellets

without the use of glues or binders.

The market offers different types of pellet with characteristics which

vary depending on what mixture of woods is used. The diameter goes

from 6 mm to 8 mm and the standard length is between 5 mm and 30

mm. A good quality pellet has a density between 550 kg/m

and 700

kg/m

with a water content that is between 5% and 8% by weight.

In order to guarantee the stated hourly consumption rates and

to optimise combustion, for pellet stoves MCZ has prepared a

patented method which makes it possible to identify and

classify any kind of pellet with a diameter of 6 mm and 8 mm

based on its specific weight and piece size.

By using the special PelletBox® and following the procedure set out in

the paragraph on lighting the stove, the user can determine the correct

settings for configuring the stove.

Along with being an ecological fuel which makes the best use of wood

residues thus producing cleaner combustion than that produced with

fossil fuels, pellets also have technical advantages. Whereas good wood

has a calorific power of 4.4 Kw/kg (with 15% humidity, so after about

18 months of seasoning), that of pellets is 5.3 Kw/kg.

To guarantee good combustion, the pellets must be stored in a clean,

dry place. The pellets are usually supplied in 15 kg. sacks, therefore

storage is very handy.

Good quality pellets ensure good combustion, thus lowering the

emission of harmful agents into the atmosphere.

The poorer the quality of the fuel, the more

frequently will intervention be necessary for cleaning

the internal parts, such as the grate and the

combustion chamber.

The pellets must be produced from pure wood which has not been

treated chemically.

The standards DIN 51731 and ONORM M 7135 certify a high-quality

pellet with the following characteristics:

 Calorific power: 5.3 kW/kg

 Density: 700 kg/m

 Moisture content: 8% max by weight

 Ash percentage: 1% max by weight

 Diameter: 6-6.5mm

 Length: 30 mm max

ENGLISH

 Content: 100% untreated wood, with no added bonding

substances (bark percentage 5% max)

 Packaging: in bags made from ecologically compatible or

biodegradable material

MCZ emphatically recommends using certified fuel

in its stoves.

The use of fuel of inferior quality or not conforming

to the specification given above compromises the

running of your stove and can therefore lead to the

termination of the guarantee and of the

manufacturer's responsibility for the product.

MCZ pellet stoves operate exclusively with pellets

with a diameter of 6 mm (only for Italy) and 6-8mm

(European countries) with a length between 5mm

and 30mm.

2.2. PRINCIPLES OF OPERATION

The pellets are picked up from the hopper on board the stove and

transported by a feed screw. They are then introduced into the

combustion chamber and fall directly into the stainless steel grate.

The quantity of pellets introduced into the grate and the corresponding

air of combustion are predetermined, programmed and controlled by an

electronic board.

In the lighting phase, the electronic board activates the smoke

extraction fan and the ceramic sparkplug, which heats up and causes

the fuel to ignite at a temperature of about 200°C. After about 20

minutes, the lighting phase is complete, and the control unit puts the

stove into operating mode.

In this phase, on the basis of the instructions which we provide via the

infrared remote (5 power levels), the electronic board regulates the

exact relationship between quantity of fuel, combustion air and

convection air, and provides continuous monitoring of all the

components connected to it, indicating if necessary the presence of any

operating problems and stopping the process.

2.3. WORKING ENVIRONMENT

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 m

/h must be

available) ,as laid down in the standard governing the installation (UNI

- CIG 7129, 7131 and in accordance with national standards in effect).

The volume of the room must not be less than 30 m

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 cm

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 may be drawn from rooms next door to the room

which needs ventilation, provided that these rooms have an air intake

from outdoors 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.

It is not permissible to install the stove in bedrooms,

bathrooms or showers, and 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 walls are not flammable, position the stove with a clearance to

the rear of at least 10 cm

In the case of walls made of flammable material, maintain a minimum

clearance to the rear of 20 cm, a clearance to the sides of 50 cm, and a

clearance to the front of 150 cm If the room contains objects which

are believed to be particularly delicate, such as hangings, sofas and

other furniture, their distance from the stove should be considerably

increased.

If there is wood flooring, place a floor protection

and adhere to national standards currently in effect.

2.4. PRECAUTIONS

IMPORTANT !

Installation and assembly of the stove must be

carried out by a qualified engineer.

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

• provided with 230V 50 Hz (EN73-23) electricity supply

• capable of taking an adequate system for smoke discharge

• provided with external ventilation

• provided with an earth connection complaint with CE standards

The stove must be connected to a flue pipe or an internal or

external vertical conduit conforming to the current standards.

The stove must be positioned in such a way that the electrical

plug is accessible.

IMPORTANT !

The stove must be connected to a flue pipe or a

vertical conduit 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.

2.5. 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.

To do this, make a hole in the external wall near the stove with a

clearance section of at least 100 cm². (12 cm diameter hole or square

10x10cm), protected by a grille on the outside.

The air intake must:

• communicate directly with the room where the stove is installed

• 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

PELLET STOVES Chapter 2

INSTALLATION AND USE MANUAL

page 14

Theoretical notes for installation Technical service – Rights reserved MCZ S.p.A. – Reproduction prohibited

ENGLISH

It is not compulsory to connect the air intake directly

with the stove (so that it draws air directly from

outside), but it is essential at all events to ensure an

airflow of 50 cubic metres per hour by the use of a

hole of the dimensions given.

See standard UNI 10683 REV.

2.6. CONNECTION OF THE SMOKE DISCHARGE PIPE

When making the hole for the passage of the smoke discharge pipe, it

is necessary to take into account the possible presence of flammable

materials. If the hole will be going through a wall made of wood or any

other material which is sensitive to heat, the INSTALLER MUST first

of all use the special wall union (diam.13cm minimum) and properly

insulate the pipe of the stove that passes through it, using adequate

insulation materials (thickness1.3—5 cm with minimum thermal

conductivity of 0.07 W/m°K).

The same is true if the stove pipe must run through vertical or

horizontal stretches passing in proximity (min.20cm) to the heat-

sensitive wall

As an alternative we recommend the use of insulated pipe, which can

also be used on the outside to avoid condensation.

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.

Pipes and unions with suitable gaskets must always

be used, to guarantee a hermetic seal.

All sections of the smoke duct must be accessible for

inspection and removable to enable periodic internal

cleaning. Tee connectors with inspection caps should be

used.

Position the stove in consideration of all the instructions and

considerations above.

IMPORTANT !

All 90 degree changes of direction in the flue pipe

must be fitted with suitable tee connectors to allow

the possibility of inspection (see the pellet stove

accessory list).

It is absolutely unacceptable to fit a grille on the end

of the discharge pipe, because it could lead to poor

running of the stove.

FOR FLUE PIPE CONNECTION DO NOT USE MORE

THAN 2-3 M. OF HORIZONTAL PIPES AND DO NOT

USE MORE THAN THREE 90° BENDS

2.7. CONNECTION TO THE FLUE PIPE

The flue pipe must have internal dimensions not greater than 20x20

cm or a diameter of 20 cm; in the case of larger dimensions or poor

operation of the flue pipe (e.g. cracks, poor insulation, etc.) it is

advisable to insert a stainless steel pipe of a suitable diameter all the

way up to the top. Fig.5

Check with suitable instruments that there is a minimum draught of 10

Pa.

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.

It is compulsory to check that an anti-wind chimney has been installed,

in accordance with current standards.

This type of connection ensures the evacuation of the

fumes even in the event of a temporary power cut.

2.8. CONNECTION TO AN EXTERNAL FLUE WITH

INSULATED OR DOUBLE-SKINNED PIPE

The outside flue must have minimum internal dimensions of 10X10 or a

diameter of 10 cm and maximums 20x20 cm or a diameter of 20 cm;

Check with suitable instruments that there is a minimum draught of 10

Pa. Fig.6

The only type of pipe which is permissible is insulated (double-walled)

stainless steel, smooth on the inside, fixed to the wall. Flexible stainless

steel pipe must not be used.

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.

It is compulsory to check that an anti-wind chimney has been installed,

in accordance with current standards.

This type of connection ensures the evacuation of the

fumes even in the event of a temporary power cut.

2.9. CONNECTION TO FLUE PIPE OR SMOKE DUCT

For proper functioning, the connecting pipe between the stove and the

chimney or flue duct must have a slope of not less than 3%. The length

of the horizontal stretch must not exceed 2/3 metres, and the vertical

distance between one tee connector and another (change of direction)

must not be less than 1.5m.

Check with suitable instruments that there is a minimum draught of 10

Pa. Fig.7

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.

2.10. OPERATING ABNORMALITIES DUE TO FLUE

DRAUGHT PROBLEMS

Of all the meteorological and geographical factors which affect the

operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to

sun, exposure to cardinal points, etc.) the wind is undoubtedly the most

important one. In fact, apart form the thermal difference caused by

the temperature difference inside and outside the chimney, there is

another kind of pressure difference: the dynamic pressure caused by

the wind. Updrafts always increase the depression and hence draft.

Horizontal wind increases draught if the chimney has been properly

installed. A downdraft always decreases the 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 indirectly affects the operation of the fireplace, creating

high and low pressure areas not only outside but also inside dwellings.

In rooms directly exposed to the wind (2) a high pressure area may be

created which may favour the draught of stoves and fireplaces, but

which may be contrasted by high external pressure if the chimney is

exposed to the wind (1). On the contrary, in rooms opposite to the

direction of the wind (3) there may be a dynamic low pressure area

which competes with the natural thermal depression in the fireplace,

which may however at times be compensated by placing the smoke

duct on the side opposite from the wind (4)

IMPORTANT !

The operation of the pellet stove is noticeabl

sensitive to the conformation and position of the flue

which is adopted.

Hazardous conditions can only be overcome by

suitable setting-up of the stove carried out by

qualified MCZ personnel.
