2 PRODUCT INFORMATION
2.1 PRODUCT DESCRIPTION
This appliance is:
- a heat generator designed to be run with pellets
- to be used solely for the purpose for which it was designed; all
other uses are to be considered improper and therefore dan-
gerous
- equipped with a flue evacuation fan which maintains the com-
bustion chamber in negative pressure.
The use of a fuel which can be easily transported and stored such
as pellets, facilitates the ease of use of this appliance.
Heat diffusion is also ensured by the Multifuoco System forced
ventilation system offering different personalised functions and
the option of ducting.
The control unit allows the user to manage a range of functions
and programmes, while the basic controls can also be managed
using the control panel on the appliance itself.
The pellets are loaded into the hopper manually and the ignition
is electronic.
An electronic control unit controls the pellet dosing into the grate
as well as the flue gas expulsion.
The unit controls the appliance to make sure it operates correctly.
Thanks to a series of safety devices, it signals any faults and, if nec-
essary, initiates the appropriate procedures.

2.3 SAFETY DEVICES
The appliance is equipped with the following safety and check
devices which stop the stove from operating if any faults occur
against over-firing and ensuring heaters is operating properly, in-
cluding ensuring visible emissions are minimized.
If any safety warnings or alarms are activated, please consult the
“ OPERATING INSTRUCTIONS ”.
Pressure switch:
controls the vacuum inside the appliance. The pressure switch is
activated if the correct operating conditions are altered (inappro-
priate use or installation, obstacles or blockages in the flue, lack
of maintenance, adverse weather conditions such as persistent
wind etc.). The pressure switch activates and isolates the supply
voltage to the auger, thus stopping pellet feed to the grate and
then initiates the appliance shut down process.
Fuel hopper thermal cut-out:
this is a thermal device with automatic rearming that serves to
safeguard the pellet hopper against excessive temperatures.
If the temperature of the hopper exceeds the safety threshold, the
device isolates the supply voltage to the auger, pellet feed to the
grate is stopped and the appliance shut-down procedure begins.
Smoke temperature probe:
this is connected to the electronic control unit and constant-
ly monitors the operating temperature. If during this phase the
smoke temperature:
a) exceeds the safety threshold, the electronic control unit isolates
the supply voltage to the auger, thus stopping pellet feed to the
grate and starting the appliance shut down process
b) falls below the minimum operating temperature, the appliance
stops and an acoustic alarm signal is activated.
Furthermore, if during the start-up phase a system malfunction is
detected, an acoustic alarm signal is activated.
Auger safety:
the operation of the auger is constantly monitored by the elec-
tronic control unit. In the event of a malfunction, an acoustic
safety signal is activated. The electronic control unit isolates the
supply voltage to the auger, thus stopping pellet feed to the grate
and starting the appliance shut down process.
Extractor fan safety:
the rotation of the extractor fan is constantly monitored by the
electronic control unit. In the event of a fan malfunction, an
acoustic alarm signal is activated. The electronic control unit iso-
lates the supply voltage to the auger, thus stopping pellet feed to
the grate and starting the appliance shut down process.
Electrical safety:
the appliance is protected by fuses in the event of a power surge.
Electronic control unit:
the electronic control unit signals and controls a series of events
including power and ignition failure.
d The safety devices are there to eliminate the risk of
damage or injury to persons, animals or objects. IT IS
FORBIDDEN to tamper with the safety devices or allow
any intervention to be carried out by non-qualied per-
sonnel.
2.4 CHECK DEVICES
The appliance is equipped with some check devices which are to
be used exclusively by personnel authorised to carry out fine tun-
ing operations during installation and maintenance procedures.
Pressure plug (A) : for measuring the pressure drop inside the
appliance.
DB9 serial port (B) : to carry out checks on the correct operation
of the product and any necessary maintenance operations. A re-
mote appliance-management system (GPRS or Wi-Fi) can be con-
nected to the DB9 serial port.

3.1 PELLET SPECIFICATIONS
d Under no circumstances use fuel other than pellets.
d DO NOT use pellets with dimensions other than those
recommended by the manufacturer.
Owner and operators of wood heaters certified to burn pel-
let fuels must only burn pellets that have been specified in the
owner’s manual and graded under a licensing agreement with a
third-party organization approved by the EPA . The Pellet Fuels In-
stitute, ENplus and CANplus are initially deemed to be approved
third-party organizations for this purpose. Additional organiza-
tions may apply to the Administrator for approval.
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. Pel-
let fuel quality can fluctuate from manufacturer to manufacturer,
and even from bag to bag.
Since the characteristics and quality of the pellet considerably
affect product performance, efficiency and proper operation, we
recommend that you use "premium grade" pellets.
In order to guarantee efficient product operation, Gruppo Pi-
azzetta S.p.A. has tested and programmed its own products with
pellets with the characteristics as shown in the table.
Minimum fuel specifications
Original raw material Natural pure wood pellet
Length 1/4" - 1 1/4" (6 - 32 mm)
Diameter 0.23" - 0.285" (6 - 7 mm)
Net calorific value ≥ 7500 Btu/lb (4.8 kWh/kg)
Density ≥ 38 lb/ft3(609 kg/m3)
Moisture < 8 %
Inorganic fines ≤ 1 %
Chlorides ≤ 300 ppm by weight
Ash content ≤ 1 %
Contains no demolition or construction waste
Trace metals ≤ 100 mg/kg
Using good quality pellets but with dimensions and heat-produc-
ing properties different from those above may require the appli-
ance operating parameters to be changed.
a This "customisation" of appliance operating settings
must only be carried out by a T.A.C. (technical assis-
tance centre) or by specially qualied personnel au-
thorised 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.
d DO NOT use pellets containing sawdust, bark, maize,
resins or chemical substances, additives or adhesives.
■ DO NOT use damp pellets.
The technical characteristics can be determined only using the
relevant tools, but a visual check at the time of purchase can serve
to identify:
- good quality: shiny, smooth, regular length, minimal dust
- poor quality: horizontal and diagonal splits, irregular length,
abundant dust
Choosing other unsuitable pellets may:
- obstruct the grate and flue gas pipe
- increase fuel consumption yet reduce performance
- mean that proper stove operation cannot be guaranteed
- cause dirt to build up on the glass
- leave particles which have failed to burn and heavy cinders.
The presence of moisture in the pellets increases their vol-
ume and causes them to split which in turn causes:
- malfunction of the fuel-loading system
- inefficient combustion.
Performance
Higher ash content requires more frequent maintenance.“Premi-
um” grade pellets will produce the highest heat output.

PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
DT2005161_H072534EN0_02
14
Pellets must be stowed in a dry, sheltered place that complies
with the relevant safety clearances from the appliance and
from heat sources which could cause combustion.
Wood pellets should be left in their original sealed bag until ready
to use, to prevent moisture. Do not store fuel within the specified
clearance areas, or in a location that will interfere with routine
cleaning and maintenance procedures.
Ash
The ash content of the fuel and operation of your stove will direct-
ly determine the frequency of cleaning.
The use of high ash fuels may result in the stove needing to be
cleaned daily. Pellets made from hardwoods generally produce
more ash than those made from softwoods.
Clinkers
Minerals and other non-combustible materials, like sand, will turn
into a hard glass-like substance when heated.
Trees from different areas will vary in mineral content. For this rea-
son, some fuels will produce more clinkers than others.
3.2 INFORMATION REGARDING PELLET
LOADING
In order to load pellets into the hopper, we recommend removing
the bag flap opening and emptying it into the hopper. This way,
the loading operation is easier and you avoid spilling the pellets
over the appliance.
d Do not allow the build-up of residue at the bottom of
the hopper.
■ Do not empty any residue from the pellet bag into the
hopper.
■ During loading operations, make sure that no pellets
fall out of the hopper as they could come into contact
with hot surfaces and ignite.
■ Do not leave leftover pellets on top of the stove: they
could catch re.
■ Do not ll the pellet hopper in excess of normal capaci-
ty and do not compress the fuel.
■ Don't remove the protective grill inside the pellet hop-
per.
a Some appliances are equipped with a protection grille
inside the hopper. Removing this grille is forbidden.
■ Only keep the cover of the pellet hopper open for as
long as it takes to complete the rell operation. To en-
sure optimal operation, some models activate an error
signal in the event the hopper cover is left open for a
time exceeding the set time.
3.2.1 Pellet indicator
When the red reload indicator can be seen inside the hopper, it is
possible that the auger is not perfectly loaded which would cause
irregular pellet unloading in the grate and start-up failure.
Fig. 7
a DO NOT LOAD PELLETS WHEN APPLIANCE IS ON if the
red rell indicator is visible inside the pellet tank.
Follow the instructions below if the red refill indicator is visible:
- switch off the appliance
- with the appliance off, reload the hopper
If the auger is even partially emptied, it is probable that the first
start-up attempt may fail.
In this case, refer to the manual " OPERATING INSTRUCTIONS " in
the sections " FILL AUGER " and " MESSAGES  SAFETY WARNINGS
 ANOMALIES ".
If an alarm is triggered, deactivate the appliance by pressing the
ON/OFF key for a few moments, remove the fuel to be found in
the grate and set a new ignition cycle.
Any unburned pellets to be found in the grate must be disposed
of.

4 GENERAL INFORMATION REGARDING
THE SYSTEM
Below is some general information regarding the system, appli-
ance installation and products manufactured by Gruppo Piazzet-
ta S.p.A.
i Please refer to the installation standards or other in-
formative documentation provided by the manufac-
turer for further information.
4.1 INSTALLATION ROOM
The appliance is to be installed in a room which allows installa-
tion, user and maintenance operations to be performed safely
and easily.
Contact local building authority before installation to determine
if a permit and/or inspection is required.
When locating your appliance, consider the building structure to
ensure the vent will not interfere with any ceiling joists, roof raft-
ers, wall studs, water pipes or electrical wiring. It may be easier to
relocate the appliance than to rework the building structure.
The layout of your house and the location of the pellet stove will
determine how effective it is at heating the intended area (e.g., in
main living area versus basement versus outdoors in sub-freezing
temperatures).
Pellet stoves use mainly air circulation to disperse their heat,
therefore a central location works best.
Consider the following things when selecting a location:
- use of an existing chimney
- location of vent termination
- aesthetic considerations
- interference with house framing, plumbing and wiring
- floor protection
- room traffic patterns
- proximity to combustibles
- location of air for combustion
- electrical outlet
- pellet fuel storage.
d The room where the appliance is to be installed must
comply with the following requirements:
■ It must not be used as a garage, store for combustible
material or for activities with a risk of re.
■ Locating the stove in a room with an explosive atmos-
phere is prohibited.
■ must not be smaller than stated in the regulations and
calculated by a specialist heating technician
■ must not be a bedroom, studio at, bathroom, shower
room or similar
■ it must not have a low pressure compared to the exte-
rior due to a counter draught caused by the presence
of another appliance or extractor device in the room
where the appliance is installed (eg. forced ventilation
systems or other heating systems using ventilation to
change the air).
a Appropriate ventilation in the installation room must
be ensured (refer to the section " FRESH AIR INTAKE ").
■ The installation room and the area which is to be heat-
ed must be suitable sized and have appropriate charac-
teristics in relation to the heating capacity of the appli-
ance. Compare the information provided in the section
" TECHNICAL DATA " with the power required by the
area which is to be heated.
■ If the room or the product installation area (technical
room, perimeter walls, recess, supporting walls, etc.)
are not suitably insulated, the heating capacity of the
appliance will be reduced.
■ Consult a heating technician or engineer for a correct
check and calculation of the requirement of the envi-
ronments to be heated and the corresponding regula-
tions.
■ The appliance cannot be installed or operated out-
doors, only indoors or in suitable technical rooms. In-
stalling the appliance outdoors could create dangerous
situations, cause health problems or lead to operating
faults.
a The existence of more than one appliance is only per-
mitted if allowed by the regulations and manufacturer
of each individual appliance.
■ If the existence of more than one appliance is permit-
ted, all regulations and provisions supplied by the
manufacturer of each individual appliance are to be
respected.
a Make sure that the oor of the installation room is able
to withstand the weight of the product including any
cladding, accessories and trim. If the oor does not
have a suitable load-bearing capacity, take adequate
counter-measures.
■ If the ooring is made of wood, provide a oor protec-
tion surface in compliance with current national stand-
ards.
a Have a smoke monitor/CO detector, especially in areas
that are expected to generate CO (e.g., heater fueling
areas, pellet fuel bulk storage areas).
■ Follow the smoke detector manufacturer’s placement
and installation instructions and maintain regularly.

4.2 FRESH AIR INTAKE
In order to operate normally, each appliance must be provided
with the air needed for combustion.
If a number of appliances are to co-exist, sufficient airflow must
be guaranteed for each individual product in full compliance with
regulations and according to the manufacturer's indications.
For a question of health, in addition to providing the air flow
needed for combustion, it is also recommended that the air inside
the installation room is suitably changed.
The airflow needed for the firebox can be obtained in different
ways, for example:
- from the installation room or adjacent rooms
- by means of a fresh air intake directly into the room and with
ducting
- with a direct connection to the combustion chamber.
In brief, the fresh air intake:
- must guarantee sufficient clean air flow for combustion: air can-
not be taken from potentially polluted areas
- must have a total free cross section of at least the value indicat-
ed in the section " TECHNICAL DATA " and in any case, equal to
or greater than the section of the air intake on the appliance
- be protected by a grille or suitable protection which does not
reduce the recommended minimum section
- be positioned in such a way that it is not obstructed and main-
tenance and inspection operations are possible
- must NOT be fitted with manual closing devices that reduce the
minimum free cross-section.
Indications for airtight installations and installations with
combustion air intake directly from the outside (according to
reference standards)
Airtight installations must be carried out by connecting the com-
bustion air inlet of the appliance directly to the fresh air intake
using a connecting pipe.
The connecting pipe for the combustion air inlet of the appliance
must comply with the following requirements:
- have a diameter equal to or greater than the diameter of the
inlet on the appliance
- be of a suitable type and made from a non-combustible ma-
terial
- the pipes, the connectors used and the installation methods
must guarantee an airtight seal
- if they are connected directly to the outside, the inlet must
prevent atmospheric conditions from negatively affecting the
combustion, for example, by means of the installation of a 90°
bend at the inlet facing downwards or a shatter-proof guard.
For the product to operate correctly, the ducting must have the
characteristics specified in the section " COMBUSTION AIR CON
NECTION ".
4.3 CHIMNEY
Every appliance shall be connected to a chimney in order to dis-
charge the combustion gases outside via natural draught.
Location of the appliance and chimney will affect performance.
- Install through the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially during
lighting and die-down of the fire.
- Penetrate the highest part of the roof. This minimizes the ef-
fects of wind loading.
- Locate termination cap away from trees, adjacent structures,
uneven roof lines and other obstructions.
- Minimize the use of chimney offsets.
It is recommended that the chimney has a chamber for collect-
ing solid matter and any condensate below the connection and
which may be easily opened and inspected by means of an air
tight door

4.4 FLUE PIPE
a The stove requires a UL or ULC listed pellet vent: a vent-
ing system composed of listed, factory-built compo-
nents assembled in accordance with the manufactur-
er's instructions and determined suitable for use with
solid fuel pellet-burning appliances.
d Do not use to vent pellet appliance these venting mate-
rials and products:
−Dryer vent
−Gas appliance vent
−PVC (plastic) pipe.

PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
DT2005161_H072534EN0_02 17
a The pellet stove is not the same as other stoves. It has
a forced draught of ue gas by a fan, which keeps the
rebox in a vacuum and the entire ueway slightly
pressurized. For this reason the ue must be complete-
ly airtight and correctly installed to ensure both trou-
ble-free operation and user safety.
a The ueway must be made by specialised personnel or
rms.
■ All pellet vent pipe must be secured together either by
means provided by pipe manufacturer or by 3 screws
at each joint.
■ If vented horizontally, joints shall be made gastight in
a manner that shall be specied by the manufacturer.
■ Use silicone to create an eective vapor barrier at the
location where the chimney or outside air ducting
passes through to the exterior of the structure.
■ Using the relative pipe clips, x the ue to the wall so
that it does not weigh on the smoke fan.
d DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST
VENTING SYSTEM OF THIS UNIT.
■ DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
■ Do not connect to a ueway into which extractor hoods
discharge vapours.
a The very hot exhaust gases may cause skin burns: keep
a considerable distance away from the appliance.
■ The exhaust gases from the combustion of pellets fuel
may dirty the outside of the walls. To avoid such possi-
bility terminate the vent above the roof line.
a INSTALL EXHAUST VENT AT CLEARANCES SPECIFIED BY
THE MANUFACTURER.
■ Follow these instructions along with all local codes re-
garding installation of this appliance.
■ Do NOT use makeshift compromises when installing
this appliance, serious consequences may result.
a THE CHIMNEY AND CONNECTOR MUST BE MAINTAINED
IN GOOD CONDITION AND KEPT CLEAN.
Pipes and maximum lengths which may be used
The exhaust pipe on all stoves is 2.95” O.D. so the stove was de-
signed to accommodate a 3” stove pipe adaptor but the diame-
ters of the pipes depends on the type of installation. Your installa-
tion may require the use of 4” vent as shown in the table.

Maximum length of vertical
sections ≤ 15' (4.6 m) > 15' (4.6 m)
Where 4” (10 cm) diameter pipe must be used, connect it to the
stove flue outlet with a "TEE" connector.
Pellet stoves depend on a combustion fan to pull air through the
unit for combustion.The venting system restricts the ability of the
combustion fan to move the required amount of air through the
unit. A system with too much resistance will result in incomplete
combustion, more frequent required cleaning and poor unit per-
formance. It is always best to choose a location for the appliance
that will result in a venting system with the shortest vent length.
i Combustion optimization. If necessary, this appliance
allows a T.A.C. (technical assistance centre) or a quali-
ed personnel authorised by Gruppo Piazzetta S.p.A.
to optimize the combustion for dierent altitudes, ue
congurations and pipe dimensions by setting the fac-
tory recommended water column / Pascal dierential
rebox pressure with the use of a pressure gauge.

The use of this type of fitting must allow for the collection of con-
densate mixed with soot, which builds up inside the pipe.
It must also permit periodic cleaning of the flue without the need
to disassemble the pipes.
Single or double clean-out tees may be used.
An example is given below of a flueway connection, which allows
complete cleaning without having to disassemble the pipes.

Horizontal installations that terminate without any vertical sec-
tions of pipe are approved; however, it is recommended that the
vent system be installed with a minimum of 5’ (1.5 m) of vertical
rise above the exhaust port on the back of the stove.
Having a vertical section in the venting will help prevent smoke
from exiting the appliance during power failures.
FAILURETO PROVIDETHE NATURAL DRAFTTHAT RESULTS FROM A
VERTICAL RISE MAY RESULT IN SMOKE BEING RELEASED INTO THE
HOUSE WHEN ELECTRICITY TO THE UNIT IS INTERRUPTED WHILE
BURNING OR SMOLDERING FUEL REMAINS IN THE BURN GRATE.
It is not recommended to run vertical venting outside the heat-
ed environment where the stove is installed. Running a venting
system in a cold environment may cause the flue temperatures to
cool down too much for adequate drafting.
a Gruppo Piazzetta S.p.A. assumes no responsibility for,
nor does the warranty cover, smoke damage caused by
reverse drafting of pellet stoves under power failure
conditions or as a result of extreme negative pressure
in the home.
4.5 INTERIOR VENT INSTALLATION
This kind of installation provides the natural draft that results
from a vertical rise avoiding smoke being released into the house
when electricity to the unit is interrupted while burning or smold-
ering pellets remains in the burn grate.
General vent layout is shown in figure and the procedure is as fol-
lows:
- use a plumb line to determine location of PL Vent penetration
of ceiling
- cut hole in ceiling and frame to appropriate opening size. Fram-
ing material shall be the same as that of adjacent joist material
- install a black ceiling support from under the level of the beam
and fix using 4 twisted nails or screws, 1.5”(38 mm). Alternative-
ly, use a support attachment instead of a black ceiling support.
The attachment is suitable for openings in the ceiling from be-
low and is fixed to the beams with 4 twisted nails or screws, 1.5”
(38 mm)
- insert first vent section through support and tighten the clamp
screw. Additionally fasten the vent with four screw (max 1/2”
(13 mm) long) through the support collar and into the vent skin
- install the vent section(s) atop the first. Twist lock sections to-
gether with a clock-wise turn. Before twisting, push vent sec-
tions firmly together for proper lock barb engagement. Enough
twisting force must be applied to ensure that the collars will
compress gasket material
- firestops are required where the vent penetrates a floor or ceil-
ing. Cut a hole of the appropriate size in the ceiling/floor and
install the firestop from above or below the joist. Fasten the
firestop with nails through the corners
- continue the vent up through the roof line
- extend the vent up to the roof pitch
- slide the Flashing over the Vent until it sits on the roof line. Slip
the upper side of the Flashing base under the roof shingles. Nail
the flashing to the roof with a minimum of 8 roofing nails. Seals
the Flashing base with appropriate roofing mastic
- slide the Storm Collar down the Vent until it sits on the flashing.
Apply a bead of silicone around the top of the Storm Collar

- extend the PL Vent at least 12”(305 mm) above the roof line and
terminate with a PL listed Rain Cap. If the Vent extends more
than 6’ (1.8 m) above the roof penetration, Roof Brace Poles
and a Roof Brace Band must be used to provide lateral support.
In geographical regions experiencing sustained low ambient
temperature is recommended to enclose exterior vents below
the roof line. This help reduce condensation, soot accumula-
tion, and poor drafting
- set the Rain Cap onto the top Vent section and twist lock it to
the top Vent section
- where the vent system penetrates the air/vapor barrier, the bar-
rier must be sealed to the ceiling support or firestop.

4.6 CONNECTING TO A CONVENTIONAL
CHIMNEY
The stove may be connected to an existing Class A chimney or
a masonry chimney which meets the minimum requirements of
NFPA 211.
This kind of installation provides natural draft in the event of
a power failure, reducing the probability of burn-back and
back-drafting.
a Check that the connection to the ueway is gas/smoke-
tight.
If you wish to use an existing chimney it is strongly recommend-
ed 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.

When chimneys are relined, a chimney chase cap that reduces the
outlet of the chimney to the size of the liner is required. Extend
the exhaust vent above the chimney chase cap and finish it off
with a rain cap.
A single wall liner may need to be insulated to maintain ade-
quate exhaust temperatures in the vent system.
a Outside chimneys frequently are dicult to keep warm:
it is recommended that you insulate the liner.
Venting into the side of an existing masonry chimney must be
done through a masonry thimble. When wall penetration is nec-
essary to access a masonry chimney, use a listed PL vent wall
thimble.
When venting into a Class A steel chimney, use an appropriate PL
