Every appliance must have a vertical flue pipe operating by natural
draught to discharge the combustion gases outdoors.
The flue must:
- comply with regulations in force in the place of installation of the
appliance;
- be tight to the products of combustion, waterproof, suitably insulated,
made with materials resistant to corrosion by the gases and to stress;
- be connected to just one stove, fireplace or extraction hood (Fig. 2);
- be properly sized, with constant free internal section, equal to or
greater than the diameter of the flue pipe of the stove and at least 3.5
m in length (Fig. 2);
- be mainly in a vertical position with a deflection from the axis of no
more than 45° (Fig. 2);
- be at a suitable distance from combustible or flammable materials,
ensured by an air gap or suitable insulating material;
- be of uniform internal section, preferably round. Square or
rectangular sections must have rounded corners with a radius of at
least 20mm and a maximum ratio between the sides of 1.5 (Fig. 3-4-
5). The walls must be smooth if possible and without narrowing.
Bends must be regular and without discontinuity (Fig. 6).
It is forbidden to make fixed or mobile apertures on the flue
pipe to connect appliances other than the one to which it is
already connected.
It is forbidden to pass other air ducts or service pipes inside
the flue pipe, however large it is.
If the flue pipe is an incorrect size or installed other than in
compliance with the above instructions, Gruppo Piazzetta
S.p.A. cannot be held liable for malfunctioning of the product,
damage to property or injury to persons or animals.

The chimney stack is a device fitted on the top of the chimney that is designed to
aid dispersion of the products of combustion in the atmosphere.
The chimney stack must comply with the following requirements:
- it must have an internal section and shape the same as the flue (A);
- it must have a useful outlet section (B) of not less than twice that of the flue (A);
- the part of the chimney that emerges from the roof or remains in contact with the
outside (e.g. in the case of a flat roof), must be covered with brick or tile elements
and in any case well insulated;
- t must be built in such a way as to prevent the penetration of rain, snow and
foreign matter into the flue and to ensure that in the event of winds from all
directions and angle, discharge of the combustion products is assured (chimney
stack with down-draught cowl).
Recommended distances for correct chimney operation.
To ensure trouble-free operation of the chimney and allow correct dilution of the
products of combustion in the air, the chimney stack must be installed at the
distances given below:
- 6 - 8 metres from any buildings or other obstacles that are higher than the
chimney stack;
- 50 centimetres higher than any obstacles located at a distance less than 5 metres;
- outside the reflux area. The size and shape of this area differ according to the angle
of inclination of the roof and it is therefore necessary to adopt the minimum
heights shown below.
Example: Check the s ope of the roof (co umn
α ), and the anticipated distance of
the chimney stack from the axis of the ridge (co umn A); if the distance is greater
than “A” the height of the chimney stack may be read in (co umn H); if the distance
is ess than “A” the chimney stack must rise above the ridge by 0.5 metres.

To ensure trouble-free operation the stove/fireplace must have the
necessary air available for combustion and this is provided through the
fresh air intake.
The fresh air intake must:
- have a total free cross section at least equal to the size given in the
paragraph “TECHNICAL DATA”;
- be protected by a grille or suitable guard provided it does not reduce
the minimum recommended section;
- be in a position whereby it cannot be obstructed.
The airflow necessary for the fire may be obtained in different ways:
- through a fresh air intake direct into the room of installation;
- with ducting through pipes direct to the room of installation, increasing
the recommended minimum free cross section by at least 15%;
- from an adjacent room to the place of installation provided this air flows
freely through permanent apertures communicating with the outside.
The adjacent room from which air is taken must not have a low
pressure compared to the exterior due to a counter draught
caused by the presence in that room of another appliance in
use or of a suction device.
The permanent apertures in the adjacent room must comply
with the requirements given above.
Combustion air must not be taken from adjacent rooms used
as a garage or a combustible materials store or for activities
posing a fire hazard.

1.5 INSTALLATION ENVIRONMENT DT2010033-01
The appliance should be installed in a location which allows safe and convenient use as well as easy maintenance. f the product being installed
requires an electrical socket, the room must also be provided with an earthed power supply in accordance with current regulations.
The room where the appliance is to be installed must comply with the following requirements:
they must not be used as a garage, store for combustible material or for activities with a risk of fire.
They must not be in a vacuum in relation to the outside environment due to the effect of contrary draught caused by the presence in
the room where the fi replace is installed of another appliance or an extractor device.
Do not use two stoves, a fireplace and a stove, a stove and a wood-fired cooking range, etc. in the same environment, since the draught
of one could affect the draught of the other.
- Devices suitable for cooking food with relative hoods without an extractor fan may only be used in kitchens.
- Gas appliances of type C are allowed (refer to current legislation and regulations in the place of installation)
Gas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation)

The stove or fireplace must not be used simultaneously with collective type ventilation ducts with or without extractor fan, other devices
or other appliances such as: forced ventilation systems or other heating systems using ventilation to change the air. Such systems could
cause a vacuum in the environment of installation even if installed in adjoining or communicating rooms.
The stove or fireplace must not be used: in stairwells except in buildings with no more than two apartments; in corridors for common
use; in bedrooms; in bathrooms or shower-rooms.
Check the load-bearing capacity of the floor, referring to the weight of the product given in the paragraph “TECHNICAL DATA”.
f the floor does not have a suitable load-bearing capacity, adequate countermeasures must be taken, for example, by using a sheet metal plate to
distribute the load.
Check the heating capacity of the appliance by comparing the rated power given in the paragraph “TECHNICAL DATA” with the power required by the
environment to be heated.
The energy requirement may be calculated approximately by multiplying the square metres of area by the height of the ceiling; the result is then
multiplied by a coefficient, which depends on the degree of insulation of the building, that is, on internal and external factors of the dwelling:
a) Internal factors: type of window and door frames, thickness of the insulation and walls, type of building materials, presence of stairwells, walls with
extensive glazing, high ceilings, position of the rooms to be heated in relation to other adjacent heated or unheated rooms, …
b) External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude, …
Example of approximate al ulation of the energy requirement to heat a fixed volume to 18/20° C:
The oeffi ient that is norma y used is determined according to the rea conditions as they occur case by case.
- From 0.04 to 0.05 kW per cubic metre in a well insulated environment
- From 0.05 to 0.06 kW per cubic metre in a poorly insulated environment.
3 rooms measuring 20m2 X (H eiling) 2.7m = 162 m3 (volume)
In an environment with a good degree of insu ation, an average va ue (coefficient) of 0.045 kW may be taken
162 (volume) X 0.045 (kW) = 7.3 kW ne essary (6300 k al/h)
Conversion 1kW = 860 kca /h
Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see
“REFERENCE STANDARDS”).

nstall the product in compliance with the recommended safety
distances from heat sensitive or inflammable materials, from load
bearing and other walls and also from wooden elements, furniture, etc.
n the case of flooring that is heat sensitive or inflammable the floor must
be protected with non-combustible insulating material, e.g. sheets of
steel plate, marble, tiles, etc.
The minimum distances are:
Connection to the flue must respect the 40 cm minimum safety
distance from heat-sensitive structural components or inflammable
materials (wood panelling, beams or ceilings, etc).
Keep any combustible product such as wooden furniture,
curtains, carpets, combustible liquids, etc. well away from
the stove when it is lit (minimum distance 80 cm).
It is advisable to leave more than the recommended 20 cm
gap at the side of the stove to facilitate any maintenance on
the appliance.
The pellet stove is not the same as other stoves. It has a forced
draught of flue gas by a fan, which keeps the firebox in a vacuum
and the entire flueway slightly pressurised. For this reason the
flue must be completely airtight and correctly installed to ensure
both trouble-free operation and user safety.
- The flueway must be made by specialised personnel or firms, as outlined
below.
- The flue must be installed in such a way as to guarantee that periodic
cleaning can be carried out without dismantling any parts whatsoever.
- Pipes should always be sealed with silicone (not cement-based sealants)
or specially adapted gaskets/seals, which retain their strength and
elasticity at high temperatures (250°C), and should be fixed with 3.9 mm
ø self-tapping screws.
Do not install dampers or valves that could block the passage of
flue gas.
Do not connect to a flueway into which other appliances (boilers,
extractor hoods, etc.) discharge fumes or vapours.

Pipes and maximum usable lengths
Pipes of painted aluminium-clad steel (minimum thickness
1.5mm), stainless steel (A S 316) or enamelled steel (minimum
thickness 0.5mm) with a nominal diameter of 80 or 100 mm (for
pipes which run inside the flue maximum diameter 150 mm) can be
used.
The male-female connectors must have a minimum length of 50
mm.
The diameter of the pipes depends on the type of installation. The
stove was designed to take 80 mm diameter pipes but, as shown
in Table 1, in some cases the use of double-lined 100 mm diameter
pipes is recommended.
Losses in pressure associated with a 90° bend can be
compared to those incurred by one metre of pipe. An
inspectable union-tee can be considered equivalent to a 90°
bend.
EXAMPLE: : if insta ing a section greater than 4.5m in ength with
80mm diameter pipe, ca cu ate the maximum usab e ength in the
fo owing ways:
- If a maximum of three 90° bends are used, the maximum ength of
the section wi be 4.5m
- If a maximum of two 90° bends are used and bearing in mind that a
90° bend can be rep aced by one metre of pipe, the maximum ength
of the section wi be 4.5m+1m=5.5m
- If a maximum of one 90° bend is used and bearing in mind that a 90°
bend can be rep aced by one metre of pipe, the maximum ength of
the section wi be 4.5m+1m+1m=6.5m
Where 100mm diameter pipe must be used, connect it to the stove
flue outlet with a 80mm union-tee then use a 80mm 100mm adaptor
(not supplied by Superior) (Fig. 19).
Union-tee
The use of this type of fitting must allow for the collection of
condensate mixed with soot, which builds up inside the pipe. t must
also permit periodic cleaning of the flue without the need to
disassemble the pipes.
This type of fitting can be bought at Superior retail outlets together
with the pipes.
An example is given below of a flueway connection, which allows
complete cleaning without having to disassemble the pipes (Fig 20).

f you wish to use an existing chimney it is strongly recommended that
you have it checked by a professional chimneysweep to ensure that it
is completely airtight. The reason for this is that the smoke, because it
is slightly pressurised, can infiltrate any cracks in the flue and escape
into living spaces. f upon inspection you find that the chimney is not
completely sound, it is recommended that you insert piping made of
new material. f the existing chimney is wide enough we recommend a
pipe with a maximum diameter of 150mm. t is also recommended that
you insulate the chimney flue (Fig. 21-22).
Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended
for connection to the flueway, since they are sized to fit the flue outlet
of the appliance.
Other pipes may be applied after adaptation and checking of the
compatibility of the coupling, taking into account that the pipes and
bends must be made in compliance with current regulations. n this
case, however, Gruppo Piazzetta S.p.A. only guarantees trouble-free
operation for parts that it manufactures and that are used according to
specifications.
Connection to the flue must respect the 40cm minimum safety
distance from heat-sensitive structural components or inflammable
materials (wood panelling, beams or ceilings, etc). (See figures 17-18).
- f the connector has to pass through partitions or walls of inflammable
or heat-sensitive materials, or through load-bearing walls, create:
an insulating barrier equal to or greater than 10cm around the
connector using mineral-based insulating material (rock wool,
ceramic fibre) with a nominal density greater than 80kg/m3.
- f the connector has to pass through non-flammable partitions or
walls, create:
an insulating barrier equal to or greater than 5cm around the
connector using mineral-based insulating material (rock wool,
ceramic fibre) with a nominal density greater than 80kg/m3.
- Check that the connection to the flueway is gas/smoke-tight, since
the appliance operates in a vacuum.
- Check that the pipe does not penetrate too far into the flueway,
thereby choking the pipe for the passage of smoke and combustion
gases.
Ensure that all installation work is carried out to professional
standards.

1.12 PREVENTION OF DOMESTIC FIRES DT2010027-02
The product must be installed and used in compliance with the manufacturer’s instructions and European and national standards as well as local
regulations.
When a flue pipe passes through a wall or a ceiling, special installation methods must be applied (protection, thermal insulation,
distances from heat-sensitive materials, etc.) See the paragraph “FLUEWAY”
- t is also recommended that all elements made of combustible or inflammable material, such as beams, wooden furniture, curtaining, flammable
liquids, etc. be kept outside the heat radiation range of the stove and in any case at a distance of at least 80 cm from the heating block.
- For other information, see the paragraph “ INI U SAFETY DISTANCES” and “CONNECTION TO A CONVENTIONAL CHI NEY”.
- The flue pipe, chimney stack, chimney and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least
twice during the seasonal period from the lighting of the stove and during its use. When the stove has not been used for some time it is advisable
to carry out the checks mentioned above. For further information, consult a chimneysweep.
- Only use recommended fuels (See section “FUEL”).

To prevent accidents or damage to the product we recommend the
following:
• unpacking and installation must be carried out by at least two people;
• every operation involving movement of the product must be carried
out with the proper tools in full compliance with current safety
regulations;
• the packaged product must be kept in the position according to the
directions shown by the diagrams and notices on the pack;
• if ropes, straps or chains are used, ensure that they are able to take
the weight of the pack and that they are in good condition;
• use slow continuous movements when moving the pack to avoid
jerking the ropes, chains, etc.;
• do not tilt the package excessively to avoid toppling;
• never stand in the vicinity of loading/unloading equipment (forklift
trucks, cranes etc).
Unpack the product being careful not to damage or scratch it,
take the accessories pack and any pieces of polystyrene or
cardboard used to wedge moveable parts etc. out of the stove
firebox.
Keep packaging (plastic bags, polystyrene, etc.) out of reach
of children, since it could be a potential source of danger, and
dispose of according to local regulations.
The wood pellet is obtained by pressing wood sawdust left over from the
working of natural dried wood. The typical small, cylindrical form is obtained
by passing the material through a die. Thanks to lignin, a natural element
which is released during the pressing of the raw material, the pellets acquire
a good consistency and compactness without requiring treatment with
additives or caking agents.
There are various types of pellet on the market with qualities and
characteristics that vary depending on the processes they have undergone
and the type of wood used in their production.
Since the characteristics and quality of the pellet considerably affect
stove performance, efficiency and proper operation, we recommend that
you use high-quality pellets.
Gruppo Piazzetta S.p.A has tested and programmed its stoves and can
ensure best performance and trouble-free operation using pellets with
the following specific characteristics:
To ensure trouble-free operation:
DO NOT use pellets with dimensions other than those recommended by the
manufacturer
DO NOT use poor quality pellets containing sawdust, bark, maize, resins or
chemical substances, additives or adhesives.
DO NOT use damp pellets.
Choosing other and unsuitable pellets:
- obstructs the grate and flue gas pipes
- increases fuel consumption
- reduces efficiency
- means that proper stove operation cannot be guaranteed
- causes dirt to build up on the glass
- leaves particles which have failed to burn and heavy cinders
The presence of moisture in the pellets increases their volume and
causes them to split which in turn causes:
- malfunction of the fuel-loading system
- inefficient combustion
Pellets should be stored in a sheltered, dry place.
To use good quality pellets with dimensions and heat-producing properties
other than those recommended above, it will be necessary to change the
stove operating parameters.
This “customisation” of stove settings must be carried out at a
Gruppo Piazzetta S.p.A. Service Centre or by specially qualified
personnel authorised by Gruppo Piazzetta S.p.A.
Using pellets that are out of date or not in conformity with the
manufacturer’s recommendations not only damages the stove and
jeopardises its performance, but can render the guarantee null and
void and relieves the manufacturer of all liability.

• Do not use the stove as a cooking appliance.
• Ensure that the room in which the stove is installed is sufficiently well ventilated (fresh air intake).
• Ensure that all joints in the flue are hermetically sealed using a silicone- (not cement-) based sealant which is resistant to temperatures of up
to 250ºC and which shows no sign of deterioration.
• Check (or have checked) regularly that the flue is clean.
• Under no circumstances use fuels other than pellets.
• Remove any deposits of unused pellets left by failed ignition before restarting the stove.
During operation some parts of the stove (door, handle, controls, ceramic parts) can reach high temperatures. Take great care and
all the necessary precautions, especially in the presence of children, the elderly or disabled and pets.
Keep any inflammable object well away from the stove while it is in use ( INI U 80 cm from the front panel).
While in use the door must remain closed and the glass must be present and intact.
The removal of the protective grille inside the pellet hopper is strictly prohibited.
If replenishing with pellets while the stove is lit, ensure that the bag does not come into contact with any hot surfaces

If the appliance does not ignite properly the main cause could be either insufficient maintenance (consequently refer to the “Maintenance”
section) or the poor quality of the pellets (refer to the “Fuel” section). It is therefore recommended to chec as above before attempting to relight
the appliance.
If the stove occasionally fails to ignite it could be caused by:
- pellet composition or size not in compliance with the specifications given in this boo let (see the “FUEL” section);
- insufficient mains voltage, whether in the form of intermittent voltage drops or a constantly lower value.
In the above cases any call-out of the service centre is not covered by the warranty, since the problem is not due to a defect in the product.
