2. THEORETICAL RECOMMENDATIONS FOR INSTALLATION
2.1. THE PELLET
Pellets are obtained from sawdust drawing produced when working
natural dried wood (unpainted). The compact nature of the material is
ensured by the lignin that is contained in the wood itself and allows
pellets to be produced without using glue or fixing materials.
There are various types of pellet on the market, with characteristics that
vary depending on the mix of wood used. The diameter of the pellets
varies between 6 and 8 mm and the standard length is between 5 and 30
mm. Good quality pellets have a density that varies between 600 and
over 750 kg/mc and a water content that is kept between 5% and 8% of
the pellet's weight.
As well as being an eco-friendly fuel that makes maximum use of wood
residues to obtain cleaner combustion than fossil fuels, pellets also offer
technical advantages. While a good wood has a calorific value of 4.4
kW/kg (15% humidity after approximately 18 months of ageing), pellets
have a calorific value of 4.9 kW/kg.
Pellets must be kept in a dry place protected from dirt to ensure good
combustion. Pellets are usually supplied in 15 kg bags to make storage
very practical.
A good quality pellet ensures good combustion and lowers harmful
emissions into the atmosphere.
The poorer the quality of fuel, the more often the
brazier and combustion chamber must be cleaned.
The main quality certifications for pellets on the European market are
DINplus and Ö-Norm M7135. These certifications guarantee that the
following values are adhered to:
Calorific value:4.9 kWh/kg
Water content: max 10% of weight
Percentage ash: max 0.5% of weight
Diameter: 5 - 6 mm
Length: max 30 mm
Content: 100% untreated wood without any added fixing
substances (max. percentage bark 5%)
Packaging: in bags made from environmentally friendly or
biologically decomposable material
Pellet fuel
15 kg bag of fuel

PELLET STOVES Chapter 2
USE AND MAINTENANCE MANUAL page 11
Theoretical recommendations for installation Technical dept. - All rights reserved by MCZ Group S.p.A. - Reproduction prohibited
MCZ strongly recommends the use of certified fuel in
its stoves (DINplus and Ö-Norm M7135).
Using poor quality pellets or pellets that do not
comply with the indications given above
compromises the operation of your stove and may
consequently lead to decline of the guarantee and
liability for the product.
MCZ pellet stoves operate only with pellets of 5 mm
to max. 30 mm length and 6 mm diameter (in ITALY
only) or 6-8 mm diameter (in other European
countries).
2.2. INSTALLATION PRECAUTIONS
IMPORTANT!
The stove must be installed and assembled by
qualified staff.
The stove must be installed in a suitable place to allow normal opening
and regular maintenance.
The room in which the stove is installed must:
offer the correct environmental conditions for operation
be equipped with a 230V 50 Hz electrical power supply
offer a suitable smoke outlet system
be fitted with external ventilation
be fitted with an EC-compliant earthing system
The stove must be connected to a flue pipe or internal or
external vertical duct, in accordance with the applicable
standards in force.
The stove must be positioned so that the electrical plug is
accessible.
IMPORTANT!
The stove must be connected to a flue pipe or a
vertical duct that can discharge the smoke at the
highest point of the home.
The smoke does, however, result from combustion of
wood essences and may therefore soil walls if
released in contact with or close to them.
Caution: the smoke is not very visible but is very hot
and can cause burns on contact.
Before positioning the stove, holes must be made for
the smoke pipe passage and the external air inlet.
2.3. THE OPERATING ENVIRONMENT
For correct functioning and even distribution of heat, the stove should
be positioned in a location in which the air required for pellet
combustion can flow in (approximately 40 m3/h must be available), in
accordance with the installation regulations and applicable standards in
force in the country of installation.
The volume of the room should be no less than 30 m3.

PELLET STOVES Chapter 2
USE AND MAINTENANCE MANUAL page 12
Theoretical recommendations for installation Technical dept. - All rights reserved by MCZ Group S.p.A. - Reproduction prohibited
A
B
C
D
Air should enter through permanent apertures made in the walls (near
the stove) that lead to the outside. These should have a minimum
cross-section of 100 cm2.
These apertures must be made so as not to be obstructed in any way.
Air may also be taken from rooms adjoining the one to be ventilated,
provided they are equipped with an external air inlet and are not used
as bedrooms or bathrooms. These must not be rooms that present a
fire hazard, for example: garages, timber storerooms, warehouses for
flammable materials. The provisions of all the applicable standards in
force must be observed in all circumstances.
Installation of the stove is not permitted in
bedrooms, bathrooms or in any room in which
another heating appliance is installed without
an independent air inflow (fireplace, stove
etc.).
It is forbidden to position the stove in rooms
with an explosive atmosphere.
The floor of the room in which the stove is
installed must be suitably sized to withstand
the weight of the stove.
If the ventilation is not ducted, maintain a minimum distance of 20 cm
at the back (A) and sides of the stove (B). If ventilation is ducted,
maintain a distance of 2 cm at the back of the stove (C) and a distance
of 20 cm at the sides of the stove (D).
The room ventilation can be adjusted
towards the rear wall only if there is
suitable caulked ducting of the hot air
flow.
If particularly delicate objects are present, such as furniture, curtains or
sofas, increase the stove clearances substantially.
If the floor is wooden lay down a floor guard in
compliance with the applicable standards in force in
the country of installation.
2.4. CONNECTING THE EXTERNAL AIR INLET
The room in which the stove is installed MUST provide at least as much
airflow as is required for regular combustion of the appliance in the
room. This can be achieved via permanent apertures made in the walls
of the room to be ventilated, leading to the outside, or via individual or
grouped ventilation ducts.
To achieve this a through hole with a minimum free cross-section of
150 cm² must be drilled in the external wall near the stove. (12 cm
diameter or 10x10 cm square hole), protected by a grille on the inside
and on the outside.
The air inlet should also:
be directly connected to the installation setting
be protected with a grille, metal mesh or suitable protection,
provided it does not reduce the minimum cross-section.
be positioned in such a way that it cannot become obstructed
Air ventilation without ducting.
Air ventilation with ducting.

PELLET STOVES Chapter 2
USE AND MAINTENANCE MANUAL page 13
Theoretical recommendations for installation Technical dept. - All rights reserved by MCZ Group S.p.A. - Reproduction prohibited
It is not obligatory to connect the air inlet directly to
the stove (direct connection to the outside) but the
aforementioned section must ensure that
approximately 50 m³/h of air is provided.
See standard UNI 10683.
2.5. CONNECTING THE SMOKE OUTLET PIPE
When making the hole for the smoke outlet pipe you must take note of
any flammable material. If the hole must pass through a wall made
from wood or thermolabile material THE FITTER MUST begin by using
the relevant wall connection minimum diameter 13 cm) and suitably
insulate the stove pipe crossing through it using appropriate insulating
materials (thickness of 1.3 - 5 with min. heat conductivity of 0.07
W/m°K).
This instruction is also relevant if the stove pipe must cross vertical or
horizontal sections close to the thermolabile wall (min. distance 20 cm).
Alternatively, we recommend the use of an insulated industrial pipe that
can also be used externally to prevent condensation.
The combustion chamber works under vacuum. The smoke duct
through which the smoke is discharged will be under vacuum when
connected to an efficient flue pipe, as specified.
Always use pipes and connections with appropriate
seals that guarantee air- and watertightness.
All sections of the smoke duct must be accessible for
inspection and removable (us a T-union with inspection
point). This makes it possible to clean the inside of the stove
regularly.
Position the stove taking note of all the specifications and warnings
underlined so far.
IMPORTANT!
All 90° changes of direction in the smoke outlet
channel must be prepared with suitable T-unions
with inspection points (see pellet stove accessories).
It is absolutely forbidden to place a net at the end of
the outlet pipe as this may cause the stove to
malfunction.
WHEN CONNECTING THE FLUE PIPE NO MORE THAN
2 - 3 METRES OF HORIZONTAL PIPING SHOULD BE
USED AND NO MORE THAN THREE 90° BENDS
SHOULD BE USED
YOU ARE ALSO ADVISED NOT TO EXCEED A LENGTH
OF 6 METRES WITH A PIPE OF 80 mm DIAMETER

2.6. FLUE PIPE CONNECTION
The inner dimensions of the flue pipe must not exceed 20 X 20 cm or a
diameter of 20 cm. If the dimensions are larger or the flue pipe is in
poor condition (e.g. cracks, poor insulation etc.) you are advised to
insert a stainless steel pipe of a suitable diameter into the flue pipe.
This steel pipe must extend along the entire length of the flue pipe until
it reaches the top.
Use suitable tools to check that there is a minimum draught of 10 Pa.
Install an inspection point on the base of the flue pipe for regular
checks and cleaning. Checks and cleaning must be performed
annually.
Make the connection to the flue pipe using connections and pipes
recommended by us.
You MUST check that a windproof chimney is installed in accordance
with standards in force.
This type of connection (even when there is a
temporary loss of current) ensures that smoke is
discharged.
2.7. CONNECTION TO AN EXTERNAL DUCT USING
AN INSULATED OR DOUBLE-WALL PIPE
The internal dimensions of the external duct must be between a
minimum of 10 X 10 cm or a diameter of 10 cm and a maximum of 20
X 20 or a diameter of 20 cm.
Use suitable tools to check that there is a draught of 10 Pa.
Use only smooth, stainless steel, insulated (double-wall) pipes inside
the stove (stainless steel hoses are not permitted). These pipes must
be fixed to the wall.
Install an inspection point on the base of the external vertical duct for
regular checks and cleaning. Checks and cleaning must be
performed annually.
Make the connection to the flue pipe using connections and pipes
recommended by us.
You MUST check that a windproof chimney is installed in accordance
with standards in force.
This type of connection (even when there is a
temporary loss of current) ensures that smoke is
discharged.
2.8. CONNECTION TO THE FLUE PIPE
For correct operation, the connection between the stove and the flue
pipe must be at least 3% of the stove in horizontal sections. The total
length of these sections must not exceed 2 - 3 metres. The vertical
section from one T-union to another (change of direction) must be at
least 1.5 metres.
Use suitable tools to check that there is a minimum draught of 10 Pa.
Install an inspection point on the base of the flue pipe for regular
checks and cleaning. Checks and cleaning must be performed
annually.
Make the connection to the flue pipe using connections and pipes
recommended by us.

2.9. OPERATING FAULTS ASSOCIATED WITH
DRAUGHT DEFECTS IN THE FLUE PIPE
Among all the weather and geographical conditions that have an impact
on the operation of a flue pipe (rain, fog, snow, height above sea level,
sun-shy periods, exposure to cardinal points etc.), wind is certainly the
most crucial. In fact, as well as thermal depression induced by the
difference in temperature between the inside and the outside of the
fireplace, there is another type of depression (or surpression): dynamic
depression induced by the wind. Ascending wind always has the effect
of increasing depression and therefore draught. Horizontal wind
increases depression if the chimney is installed correctly. Descending
wind always has the effect of decreasing depression and sometimes
inverting it.
As well as the direction and strength of the wind, the position of the
flue pipe and chimney in relation to the roof of the house and
surrounding landscape is important.
Wind has an impact (even indirectly) on the operation of the flue,
creating areas of surpression and depression both inside and outside
homes. In environments directly exposed to wind (2), an internal
surpression can be created that can encourage draught in stoves and
fireplaces. However, this can be contrasted by external surpression if
the chimney is positioned on the side exposed to the wind (1). On the
other hand, environments facing away from the wind (3) can create a
dynamic depression that competes with the natural thermal depression
developed by the flue. However, this can be compensated (sometimes)
by positioning the flue pipe on the opposite side to the direction of the
wind (4).
IMPORTANT!
The operation of the pellet stove is
g
reatly affected by
the conformity and positioning of the flue pipe used.
Precarious conditions can usually be resolved by
setting the stove appropriately. This must be done by
qualified MCZ staff.

3.2. PREPARATION AND UNPACKING
The Philo stove is supplied in several packages:
The first package contains the stove (fig. 1)
The second contains the painted steel front panel in 2 pieces
(fig. 2)
The third contains the grille (fig. 4)
The fourth contains the upper top (fig. 5)
The packages containing the grille and the top are placed together with
the stove in the same box (fig. 1). The package containing the front
panels is placed alongside the stove package (fig. 2).
Open the package and remove the five screws from the base of the
stove (3 screws at the front and 2 at the back). These screws secure
the stove to the pallet (fig. 6). To remove the two screws behind (on
the back of the stove), two larger eyelets have been made to allow you
to insert the wrench to undo the screws.
Position the stove in the chosen place, taking care to ensure that it
complies with the specifications.

The body of the stove or unit must always be handled vertically and
only using trolleys. Pay particular attention to the door and its glazing
to protect them from mechanical knocks which would compromise their
proper working order.
In all cases, appliances must be handled with care. If possible, unwrap
the stove near the chosen place of installation.
The materials making up the packaging are neither toxic nor harmful
and, as such, require no special disposal measures.
Storage, disposal and any recycling is therefore the responsibility of the
end user and must be carried out in compliance with the applicable
laws in force.
Do not store the unit and claddings without the associated packaging.
Position the stove without the cladding and then proceed with the
connection of the flue pipe. Once the connections have been made, fit
the cladding (ceramic or steel-sided).
If you have to connect the stove to an outlet pipe that crosses the rear
wall (to flow into the flue pipe) take great care not to force the mouth.
Adjust the 4 feet (J) to find the correct level so that the smoke outlet
and pipe are coaxial. The feet must be adjusted without the steel or
ceramic sides as the adjustment occurs inside the cladding.
If the smoke outlet of the stove is forced or used
inappropriately to lift or position it the function of
the outlet will be irreparably compromised.

3.3. CONNECTING THE SMOKE OUTLET PIPE
The smoke outlet can be positioned either at the rear or at the top of
the stove.
Should you wish to connect the smoke outlet at the top of the
stove, remove the cap with the three screws from underneath the top.
Next, insert the pipe until it joins the smoke connection.
If the smoke outlet is positioned at the rear of the stove
the T-union must be turned towards the back of the stove and
the pre-perforated panel at the rear of the stove must be
removed.
Next, connect the pipes.
Remove the fixed cap with the three
screws from underneath the top of the
stove.
