- it must have a useful outlet section of not less than twice that of the flue;
- the part of the flue that emerges from the roof or remains in contact with the
outside (e.g. in the case of an open loft), must be covered with brick or tile elements and in any case well insulated. It 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);
- any buildings or other obstacles that are higher than the chimney stack must
not be too close to the actual stack Fig.8 - Fig.9;
- the chimney stack must be positioned in such a way as to ensure adequate
dispersion and dilution of the products of combustion and in any case 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 in Fig.10;

The air necessary for the fire may be obtained in different ways:
- Figure 12 through an external grille direct to the room of installation;
- Figure 13 with ducting through pipes direct to the room of installation, increasing the recommended minimum free cross section by at
least 15%;
- Figure 14 through a communicating hole from an adjacent room to
the place of installation: this system may only be used if the air flows
freely from the outside through fixed apertures;
- Figure 15 from an adjacent room to the place of installation, but only
if the air flows freely through apertures communicating with the outside.
1.5 Installation environment
The appliance should be installed in a location which allows safe and
convenient use as well as easy maintenance. If the product being
installed requires an electrical socket, the room must also be provided
with an earthed power supply in accordance with current regulations.
Fig. 13
English
1.4 Fresh air intake - Fig. 12÷15
The stove/fireplace must have the necessary air available to ensure
proper combustion.
- Make sure that the room in which the stove/fireplace is to be installed has an air intake of at least the size indicated in the paragraph
“TECHNICAL DATA”.
- The fresh air intake may be protected by an external grille provided it
does not reduce the minimum section of the recommended airflow
and is in a position whereby it cannot be obstructed.
DT2030193-00
Fig. 14
DT2030194-00
Fig. 15
The installation of a wood-burning appliance in a bedroom,
bath or shower room or in any room where another heating
system not equipped with its own air supply (fireplace, stove
etc.) has already been installed is forbidden.
The room or rooms adjacent to that where the appliance is to be installed must conform to the following requirements:
It must not be used as a car bay, a store for combustible material, nor for any activity which carries a risk of fire.
It must not be pressurised relative to normal atmospheric pressure as a result of the draught created by a prior installation of
an open fire or of an extractor system.
DT2030195-00
In the same location do not install two stoves, a stove and a fireplace, a stove and a wood-burning range etc, since the draught
from one device can interfere with the draught from another.
- The use of equipment adapted for cooking food with non-extractor
hoods is permissible only in rooms to be used as kitchens.
- Equipment using gas type C is permitted (refer to regulations in force
in the place of installation).
7
SUPERIOR
®
English
Equipment using gas type B is not permitted (refer to regulations in force in the place of installation).
Using the stove or flue simultaneously with shared ventilation
systems is not permitted, whether with or without extractor
fans. Similarly the use of other devices or equipment, such as
air-conditioning systems or other heating systems which use
fans to circulate air, is not permitted. These devices can cause
the atmosphere around the stove to become pressurised even
if installed in adjacent, communicating rooms.
1.6 Capacity load of the floor
Check the load-bearing capacity of the floor, referring to the weight of the
product given in the paragraph “TECHNICAL DATA”.
If 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.
1.7 Heating capacity
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 calculation of the energy requirement to
heat a fixed volume to 18/20° C:
The coefficient that is normally used is determined according to the real
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 ceiling) 2.7m = 162 m3 (volume)
In an environment with a good degree of insulation, an average value
(coefficient) of 0.045 kW may be taken
162 (volume) X 0.045 (kW) = 7.3 kW necessary (6300 kcal/h)
Conversion 1kW = 860 kcal/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”).
Rated power being equal, products with the Multi-fire system
can evenly distribute heat throughout the rooms to be heated.

- The construction of the exhaust system must be undertaken by specialised personnel or firms, as outlined in the following pages.
- Installation of the flue should be completed in such a way as to guarantee that periodic cleaning can be carried out without dismantling
the entire system.
- Pipes should always be sealed with silicone (not cement-based
sealants) or specially adapted washers which will retain their elastic
and resistant properties at high temepratures (250°C). These should
be attached with 3.9mm-diameter self-threading screws.
DT2030335-00
MIN 40 cm
The pellet stove is not the same as other stoves. The smoke is
propelled by a fan which keeps the combustion chamber pressurised and the entire flue system slightly pressurised. For this
reason the flue must be completely airtight and correctly installed to ensure both trouble-free operation and user safety.
MIN 40 cm
1.9 Flue system - Fig. 19-20
DT2030336-00
The installation of flaps or valves which might block the passage of the smoke is not permitted.
The installation of other devices (boilers, extractor hoods etc)
which might release fumes or vapours into the flue system is
not permitted.

Pipes and maximum usable lengths
Pipes of aluminium-clad painted steel (minimum thickness
1.5mm), stainless steel (Aisi 316) or enamelled steel (minimum
thickness 0.5mm) with a nominal diameter of 80 or 100mm (for
pipes which run inside the flue maximum diameter 150mm) can be
used.
The male-female connectors must have a minimum length of
50mm.
The diameter of the pipes used depends on the type of installation.
The stove was designed to take 80mm-diameter pipes but, as
shown in Table 1, in some cases the use of double-lined 100mmdiameter pipes is recommended.

Losses associated with a 90° bend can be compared to those
incurred by one metre of pipe. An inspectable T-connector
can be considered equivalent to a 90° bend.
DT2030337-00
Fig. 20
EXAMPLE: If installing a section greater than 4.5m in length with
80mm-diameter pipe, calculate the maximum usable length in the following ways:
- If in the section to be fitted a maximum of three 90° bends are used,
the maximum length of the section will be 4.5m.
- If in the section to be fitted a maximum of two 90° bends are used
and bearing in mind that a 90° bend can be replaced by one meter of
pipe, the maximum length of the section will be 4.5m+1m=5.5m.
- If in the section to be fitted a maximum of one 90° bend is used and
bearing in mind that a 90° bend can be replaced by one meter of
pipe, the maximum length of the section will be
4.5m+1m+1m=6.5m.
Where 100mm-diameter pipe must be used, connect it to the stove’s
exhaust outlet with a 80mm T-connector then use a 80mm-100mm
adaptor (not supplied by Piazzetta) (Fig 19).

The use of this type of connector must allow for the collection of condensation mixed with suit which builds up inside the pipe. It must also
permit the periodic cleaning of the flue without the need to dismantle
the pipes.
This type of connctor can be bought at Piazzetta outlets together with
the pipes.
Outlined below is an example of a set-up which can be cleaned entirely without the need to dismantle the pipes (Fig 20).

For connection to the chimney the use of Piazzetta’s own pipes and
bends is recommended - the stove’s outlet is the right size to connect
to these.
Other types of pipe can be used, provided that they are suitable or that
the compatibility of the connecting sleeve can be verified. Bear in mind
also that pipes and bends must be constructed according to existing
regulations. In such cases however Gruppo Piazzetta S.p.A guarantees
the proper functioning of the stove only where its own equipment has
been employed in accordance with its own instructions.

The connection to the flue system must respect the 40cm minimum
safety distance from objects which are sensitive to heat and from
inflammable materials (wooden veneers, beams or ceilings etc). (See
figures 17-18)
- If the connector has to pass through partitions or walls constructed
from inflammable or heat-sensitive materials, or through weight-bearing walls, you must introduce:
an insulated barrier equal to or greater than 10cm around the connector using a mineral-based insulating material (rock wool, ceramic
fibre) with a nominal density greater than 80kg/m3
English
1.10 Connecting to a conventional chimney - Fig. 21-22
If you wish to use an existing chimney it is strongly recommended that
you have it checked by a professional chimney-sweep 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 system and escape into living spaces. If upon inspection you find that the chimney is not
completely sound, it is recommended that you insert piping made of
new material. If the existing chimney is wide enough we recommend a
pipe with a maximum diameter of 150mm. It is also recommended that
you insulate the chimney flue (Fig. 21-22).

3.0 FUEL
Choosing pellets different to those stipulated:
- obstructs the burner and flue ducts
- increases fuel consumption
- reduces efficiency
- cannot guarantee the stove’s proper functioning
- causes dirt to build up on the glass
- leaves particles which have failed to burn and heavy cinders.
There are various types of pellet on the market with qualities and characteristics which vary depending on the processes they have undergone and the type of wood used in their production.
Since the pellet’s characteristics and quality affect to a considerably degree the stove’s performance, productivity and proper
functioning we recommend that you USE high-quality pellets.
The presence of dampness 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 sealed, dry place.
Gruppo Piazzetta S.p.A has tested and programmed its stoves and
can promise optimum performance and trouble-free functioning
using pellets with these specific characteristics:
• Material:
wood
• Length:
not greater than 30mm
• Diameter:
6-6.5mm
• Inferior heat energy:
5kWh/kg
• Humidity:
not greater than 8%
• Residual ash:
0.34%
English
The pellet stove has been designed to burn only wood in pellet form.
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 a process similar to wire-drawing. 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.
If you wish to use good-quality pellets with different dimensions and heatproducing properties to those stipulated you will need to alter the operating
parameters of the stove. This “customisation” of the stove’s settings must
be carried out at one of Gruppo Piazzetta S.p.A.’s Centres for Technical
Assistance or by specially qualified personnel authorised by Gruppo
Piazzetta S.p.A.
Using out of date pellets or those which do not conform to the
manufacturer’s stipulations damages the stove and compromises performance as well as can nullifying the guarantee
and excusing the manufacturer from his responsibilities.
To assure trouble-free operation:
DO NOT use pellets with dimensions different to those stipulated by the
manufacturer.
DO NOT use pellets which are out of date or which contain loose sawdust, resins, chemical substances, additives or caking agents.
DO NOT use damp pellets.

Upon first ignitions certain odours may be given off due to the
evaporation of paint or grease. To alleviate the problem merely air
the room, thus avoiding the prolonged exposure which may render
these emissions harmful to people or animals.
When the fuel tank is loaded for the first time the fuel-loading chute
has to fill up; during this period the pellets will not be fed into the
combustion chamber.

6.6 Safety features
During operation, some parts of the stove (door, handle, ceramic parts) can reach high temperatures.
Remember to maintain the safety distances indicated previously.
Excercise care, use all due precautions and always follow the instructions.
If during operation, any part of the stove or exhaust system begins to leak smoke, shut the stove down immediately and ventilate the
room. Then, once the stove has cooled, check for the cause of the leak and if necessary call in specialist personnel.
The stove is equipped with several safety devices which act to guarantee its safe operation.
The safety devices are there to eliminate the risk of harm to people, pets and property. Tampering or intervention on the part of
unauthorised personnel can compromise this.
Possible problem indicators
Simple running problems can usually be resolved with the help of these pages.

6.7 Opening the door
During operation the door must remain closed. It is to be opened only when the stove has shut down and cooled for the carrying out
of maintenance.
6.8 Removing the ash
The ash drawer must be emptied regularly. The ashes must never reach the level of the burner’s supporting arm.
The ashes must be put in a metal container with a sealable lid. Until the ashes are definitively extinguished, the container must be placed
on a non-combustible surface or on the ground and be kept well away from combustible material.
Ashes can conceal burning embers for long periods!!!

DT2010111-01
7.0 MAINTENANCE
7.1 Cleaning the burner and the burner support - Fig. 31
If the flame assumes a reddish colour or becomes weak, accompanied by black smoke, it means that there are deposits of ash and
other substances which are impeding the correct functioning of the
stove and which should be removed.
Every two days, remove the burner by simply lifting it out of its
position. Then clean from it any ash or other material which may
have been allowed to build up, paying particular attention to free up
any blocked holes with a pointed implement (fig 31).
This operation should be carried out at every startup, especially
if pellets other than those supplied by Piazzetta have been used.
The intervals between cleaning should be dictated by the regularity of the stove’s use by the choice of fuel.
It is always worthwhile checking the burner’s support freeing it
of any ash.
English
All maintenance work (cleaning, replacing parts, etc…) should be
carried out when the stove has been extinguished and allowed to
cooled. Furthermore, do not in any circumstances use abrasive
substances.
DT2010057-00
Fig. 31
DT2030124-00
Before lighting the stove ensure that the burner is pushed
back towards the shield.
7.2 Cleaning the ash drawer
Every two days, check the ash drawer to see if it needs to be emptied. For the removal of ash see section 5.8.
Fig. 32
7.3 Cleaning the combustion chamber - Fig. 32-33
The combustion chamber should be cleaned once a week as follows:
• Remove the internal shield raising it gently and using the flaps as
handles, then rotate it and tilt it in order to slide it through the
mouth of the combustion chamber (fig 32, 33).
• Use a vacuum cleaner to remove any ash acccumulated in the
combustion chamber.
• Having cleaned the chamber thoroughly replace the parts in
reverse order paying particular attention to the positioning of the
internal shield: it should sit snugly beside the catches on the interior of the chamber (the two catches should remain in front of the
shield).
This type of cleaning requires a vacuum cleaner suitable for
holding ash.

DT2030127-00

SUPERIOR

English
7.4 Cleaning the smoke chamber - Fig. 34÷38
Every year, clean the smoke chamber as follows:
• Remove the screws which hold the exhaust outlet’s hatch in place,
then raise it and take it out pulling it towards you (fig 34, 35).
• Use a vacuum cleaner to clean any ash and carbonous deposits
which can accumulate in the chamber, paying particular attention
not to damage the blades of the fan (fig 36, 37).
• After cleaning the chamber, thoroughly replace the hatch and if
necessary replace the lining (fig 38).
7.5 Cleaning the exhaust system
Until you have acquired experience of the effects on the stove of its
habitual use, it is recommended to carry out this operation once a
month.
Remove the cap from the T-joint and clean the pipes.
If necessary, at least the first few times, consult a qualified person.
Fig. 34
DT2030128-00
Fig. 35
7.6 Cleaning the ceramic cover
The ceramic cover should first be cleaned with a soft dry cloth
before using even delicate detergents and a damp cloth.
DO NOT SOAK THE CERAMIC AND NEVER USE COLD WATER WHEN
IT IS STILL HOT - THE THERMAL SHOCK COULD BREAK IT.
DT2030129-00
Fig. 36
7.7 Cleaning the metal parts
Clean the metal parts with a soft damp cloth.
NEVER CLEAN METALLIC PARTS USING ALCOHOLS, SOLVENTS,
PETROLEUM BASED AGENTS, ACETONES OR OTHER GREASEREMOVING SUBSTANCES.
In the case of such substances being used, Piazzetta declines every
responsibility.
Discolouration of metallic parts may be the result of improper use.
7.8 Cleaning the window
The window in the door should be cleaned (when cold) with ammonia-based degreasing agents and not with corrosives such as solvents.
Do not allow corrosive substances to come into contact with the
stove’s paintwork as this will damage it.
If the glass is hot, before cleaning, the door must remain open for
the time necessary to allow the glass to cool.
Do not use materials which might scratch or damage the glass.

7.10 Replacing the remote control battery
To change the battery proceed as follows: using a small Philips head screwdriver, remove the screw on the back of the handset. Then
holding it upside down remove the back casing. Replace the battery (type A23 12V) being careful not to reverse the polarity (the battery
type and polarity are shown on the back of the handset). Close the handset and dispose of the old battery in the appropriate way.
7.11 Cleaning the fans
Any cleaning or maintenance operation must be carried out after the CURRENT HAS BEEN SWITCHED OFF.
The stove is equipped with fans (smoke extractor and heating) positioned low down at the rear. Any buildup of dust or ash on the blades
can unbalance them resulting in noise during operation.
Therefore it is necessary to have the fans cleaned annually. Since such an operation involves dismantling certain parts of the stove, have
the cleaning carried out only by a Centre for Technical Assistance or other qualified persons.
7.12 When not in use
When shutting the stove down for the summer carry out the following:
• Remove all pellets from the fuel tank and loading system.
• Carefully clean the burner, the burner support, the combustion chamber and the ash drawer.

To replace proceed as follows:
• Wear protective gloves.
• Remove the door and lie it flat.
• Unscrew the screws visible on the inside of the door.
• Remove frame and glass carefully.
• If the lining has deteriorated, replace it.
