1.1 Single flueway or chimney - Fig. 2÷6
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 the corrosion of the gases and to
stress;
- be connected to just one stove, fireplace or extraction hood;
- 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;
- 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. 4). The
walls must be smooth if possible and without narrowing. Bends must
be regular and without discontinuity (Fig. 3 - 4 - 5).
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.
1.2 Soot inspection - Fig. 1
- The flue must have a chamber for collecting solid matter and any
condensate located below the connection and which may be easily
inspected by means of an airtight door. (Fig.1)
- The bends connecting to the flue must have inspection points that
allow the system to be checked, cleaned and maintained.

1.3 Chimney stack - Fig. 7 ÷ 11
The flue must be fitted at the top with a device called a chimney stack,
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;
- 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;
Example: Check the slope of the roof (column α), and the anticipated
distance of the chimney stack from the axis of the ridge (column A), if
the distance is greater than “A” lthe height of the chimney stack may
be read in (column H); if the distance is less than “A” the chimney stack
must rise above the ridge by 0.5 metres.

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.
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.
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.
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).

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.
®
SUPERIOR

1.8 Minimum safety distances - Fig. 16÷18
With reference to the above diagram, the minimum safe distances from
heat sensitive or inflammable materials, such as load bearing and other
walls are:
A 20 cm from the wall behind the stove
B 60 cm from the side wall
C 100 cm in the radiating area
In the case of flooring that is heat sensitive or inflammable the floor
should be protected (using for example sheets of steel plate, marble or
tiles).
The minimum distances are:
D 50 cm;
E 30 cm (measured from the internal corner of the door opening).
Keep any combustible product well away from the stove when it
is lit (minimum distance from the heat radiation area), for example:
wooden furniture, curtains, carpets, combustible liquids, etc.
1.9 Flue system - Fig. 19-20
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.
- 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.
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.
TYPE OF INSTALLATION
TABLE 1 LENGHT PIPES
WITH 80mm Ø PIPE

For installations more than 1200m above sea level - Required
Maximum number of bends 3 4

10
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.
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).
T-connector
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).

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).
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/m 3
- If the connector has to pass through partitions or walls constructed
from heat-resistant materials, you must introduce:
an insulated barrier equal to or greater than 5cm around the connector
using a mineral-based insulating material (rock wool, ceramic
fibre) with a nominal density greater than 80kg/m 3.
- Check that the connection to the flue system has been carried out so
as to guarantee that smoke will not leak from it under the equipment’s
pressurised operating conditions.
- Check that the pipe does enter too far into the flue creating a narrowing
of the exhaust passage. Figure 22-23
Ensure that all installation work is carried out to professional
standards.

1.11 Using external flue ducts
You can use external flue ducts only when they correspond to the following
requirements:
- Use only insulated pipes (double-lined) in stainless steel attached to
the outside wall (Fig 23).
- At the base of the duct there must be an inspection hatch to permit
periodic checks and maintenance.
- The installation must be equipped with an windproof chimney and
respect the safety distance from the high point of the roof as outlined
in the chapter entitled “GENERAL RULES”, under “Chimney top”.
12
Ensure that all installation work is carried out to professional
standards.
1.12 Prevention of domestic fires
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 “Connection to the flueway”.
- It is also recommended that all elements made of combustible or

DT2010233-00
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.
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.
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%
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.
DT2010074-00
During operation, some parts of the stove (door, handle, display,
ceramic parts) can reach high temperatures. Therefore take due
precautions, above all in the presence of children, elderly and disabled
persons and pets.
In order to avoid accidents or damage to the product, the following
recommendations are made:
• 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.
®
SUPERIOR
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.
3.0 FU<strong>EL</strong>
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.
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.
DT2030346-00
4.0 BEFORE UNPACKING YOUR PRODUCT
• The orientation of the packaged product must conform to the
directions given in the diagrams and notices on the package.
• If cables, straps or chains are used, ensure that they are able to
take the weight of the package and that they are in good condition.
• While moving the package use slow continuous movements to
avoid tearing cables, chains etc.
• To avoid toppling do not lean the package excessively.
• Do not stop in the path of loading/unloading equipment (cradles,
cranes etc).

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.

6.3 Startup and normal operation
Before proceeding with the ignition remember:
ensure that the furnace door is well closed;
• that the fuel tank is full or at least contains enough fuel to run for the desired period.
When the stove is connected to the power supply, but is not yet lit, the display will show the current time on its top half (example 12:30)
and the word OFF on its lower half.

STARTUP
Action Description Display
Hold the on/off key

seconds:
4
Starts a cycle of three phases which take the
stove into normal operation:
• Phase one: CHECK UP (first 10 seconds)
- The extractor fan activates for a few seconds.
• Phase two: IGNITION
- The fuel-loading chute is activated and
starts to feed pellets into the burner (the
LED on the display lights up at fixed time
intervals).
- The pilot light ignites (the LED on the display
lights up).
- The extractor fan starts up.
• Phase three: STARTUP
- If the pilot light has triggered the combustion
process, the fuel-loading chute will
slow down to allow a period of stabilisation
and therefore a complete combustion of the
pellets in the subsequent operation.
- If during the startup phase the sensor on
the exhaust outlet shows an increase in
temperature (sign that the combustion
process is underway), the stove is considered
to be lit and operating normally.
- If during the startup phase the sensor at the
exhaust outlet does NOT show an increase
in temperature (sign that the combustion
process is not underway), the stove should
be considered off; a new ignition cycle will
begin automatically and the three preceding
phases will be repeated in succession.
On the lower part three circles will appear in succession
indicating the current phase of ignition.

The thermostat is connected using cable type
2x0.5mm2 stopped with a PG7 connector and
inserted in the appropriate socket on the rear
panel (fig 3, 4). This operation should be
undertaken by authorised personnel.
To check on the display if the stove is operating
using the external thermostat, you must input a
special code which will allow the temperature to
be shown. If not, the stove will still run with an
external thermostat but there will be no reading
on the display. If during normal operation the
temperature is lower than that programmed:
• the corresponding LED on the display remains
off
• the display indicates the chosen power level
• the stove will operate at the power level input.
When the room temperature reaches the programmed
value:
• the corresponding LED lights up
• the stove runs at minimum power even if the
input power level is shown on the display.

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!!!
®
SUPERIOR

DT2010111-01
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.
®
SUPERIOR
DT2010057-00
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.
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.
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.

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.
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.
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 GREASE-
REMOVING 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.

7.9 Replacing the window
The stove is equipped with a 4mm-thick glass pane, resistant to thermal shock up to 750ºC; the glass can only be broken by a heavy
impact or by improper use.
Do not slam the door or bang into the window.
In case of breakage replace only with a Gruppo Piazzetta replacement part.
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.
• Change the pane then replace the frame, tightening the screws carefully but not excessively.
• Remount the door.
If other problems occur, consult your nearest retailer.
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.
• Clean the flue thoroughly: for this contact a professional chimney sweep.
• Clean all dust, cobwebs etc from the area behind the internal cover panels once a year, in particular the fans.
• Remove the power cable.
7.13 Extraordinary maintenance
The following operations should be carried out annually and are necessary to guarantee the stove’s efficient and safe functioning.
• Clean the combustion chamber thoroughly.
• Clean and inspect the flue.
• Check the condition of washers.
• Clean mechanical and moving parts (motors and fans).
• Check electrical and electronic components.
