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 smoke evacuation fan which maintains the
pressure in the combustion chamber (vacuum).
The use of a fuel which can be easily transported and stored such
as pellets, facilitates the ease of use of this appliance.
The temperatures, which do not reach excessive levels, together
with the humidifier increase safety of use and give the feeling of a
comfortable, diffused warmth.
A panel on the appliance allows the user to control a wide range
of functions and programming operations.
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.
This control unit oversees the correct operation of the appliance
and, thanks to a series of safety devices, signals any faults on the
panel on the appliance itself and if necessary, initiates the appro-
priate 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,
including 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 (firebox
door open, poor installation, obstacles or blockages in the flue,
lack of maintenance, adverse weather conditions such as persis-
tent wind etc.). The pressure switch activates and isolates the sup-
ply voltage to the auger, thus stopping pellet feed to the grate
and then initiates the appliance shut down process.
Hopper thermostatic probe:
this is a thermostatic probe which automatically rearms and is
located on the pellet hopper. It serves to safeguard the hopper
against excessive thermal excursions.
If the temperature of the hopper exceeds the safety threshold,
the thermostat isolates the supply voltage to the auger, pellet
feed to the grate is stopped and the appliance shut down pro-
cedure 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:
auger operation is constantly monitored by the electronic board.
If there is a malfunction which produces a continuous discharge
of the pellet, an acoustic alarm signal is activated. The electronic
control unit isolates the supply voltage to the auger, thus stop-
ping 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 have the task of eliminating any risk
of damage or injury to persons, animals or objects. IT
IS FORBIDDEN to tamper with the safety devices or al-
low any intervention to be carried out by non-qualified
personnel.
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.

3 FUEL
d Never use gasoline, gasoline-type lantern fuel, kero-
sene, charcoal lighter fluid, ethyl alcohol or similar liq-
uids to start or "reignite" a fire in this heater. Keep all
such liquids well away from the heater while it is in use.
3.1 PELLET SPECIFICATIONS
d Under no circumstances use fuel other than pellets.
Wood heaters certified to burn pellet 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 Institute, ENplus and CANplus are in-
itially deemed to be approved third-party organizations for this
purpose. Additional organizations may apply to the Administra-
tor 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.
Since the characteristics and quality of the pellet considerably
affect product performance, efficiency and proper operation, we
recommend that you use high-quality pellets: pellet fuel quality
can fluctuate from manufacturer to manufacturer, and even from
bag to bag.
In order to guarantee efficient product operation, Gruppo Pi-
azzetta S.r.l. has tested and programmed its own products with
pellets with the characteristics as shown in the table.
Minimum fuel specifications
Parts Natural pure wood pellet
Length 1/4" - 1 1/4" ( 7 - 30 mm)
Diameter 0,23" - 0,285" ( 6 - 7,2 mm)
Density 38 lb/ft3(609 kg/m3)
Moisture < 8 %
Inorganic fines ≤ 1 %
Chlorides ≤ 300 ppm by weight
Ash content ≤ 2 %
Contains no demolition or construction waste
Trace metals ≤ 100 mg/kg
d DO NOT use pellets with dimensions other than those
recommended by the manufacturer.
 DO NOT use pellets containing sawdust, bark, maize,
resins or chemical substances, additives or adhesives.
 DO NOT use damp pellets.
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.
Pellet fuel storage
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.
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.
Moisture
Always burn dry fuel. Burning fuel with high moisture content
takes energy to dry and tends to cool the appliance thus, robbing
heat from your home.
Damp pellet fuel could turn back into sawdust which does not
flow properly through the feed system.
Performance
Higher ash content requires more frequent maintenance. “Premi-
um” grade pellets will produce the highest heat output.
When using good quality pellets but with dimensions and
heat-producing properties other than those recommended
above, it is necessary to change the stove operating parameters.
a The use of cordwood is prohibited. Do not burn gar-
bage or flammable fluids such as gasoline, naphtha or
engine oil.
 This "customisation" of appliance operating settings
must only be carried out by a T.A.C. (technical assis-
tance centre) or by specially qualified personnel au-
thorised by Gruppo Piazzetta S.r.l..
 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.

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 fire.
 Do not fill 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 refill 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 (refer to the section " SAFE
TY DEVICES ").
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 refill 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.r.l.
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 fire.
 Locating the stove in a room with an explosive atmos-
phere is prohibited.
 If the flooring is made of wood, provide a floor protec-
tion surface in compliance with current national stand-
ards.
 It 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 firebox
is installed of another appliance or an extractor device.
d The appliance must not be used simultaneously with
collective type ventilation ducts with or without ex-
tractor 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.
a Make sure that the floor of the installation room is able
to withstand the weight of the product including any
cladding, accessories and trim. If the floor does not
have a suitable load-bearing capacity, take adequate
counter-measures.
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.
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.

PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
DT2003165_H072218EN0_00
14
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, non-flammable material
- 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
- If the installation requires a connection to coaxial type pipes
with the inlet of pre-heated combustion air, the materials used
must adequately resist the operating temperature.
For the product to operate correctly, the ducting must have the
characteristics specified in the section " COMBUSTION AIR CON
NECTION ".
4.3 CHIMNEY
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 listed pellet vent. So the vent-
ing system shall be approved for pellet stoves by a cer-
tified testing Laboratory.
 PL Vent must be used for venting all Freestanding
stoves.
d Do not use to vent pellet appliance these venting mate-
rials and products:
−Dryer vent
−Gas appliance vent
−PVC (plastic) pipe
−Single wall stove pipe.
a 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
pressurized. For this reason the flue must be complete-
ly airtight and correctly installed to ensure both trou-
ble-free operation and user safety.
a The flueway must be made by specialised personnel or
firms, as outlined below.
 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 specified by the manufacturer.
a Using the relative pipe clips, fix the flue 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 flueway 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.

PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
DT2003165_H072218EN0_00 15
a INSTALL EXHAUST VENT AT CLEARANCES SPECIFIED BY
THE MANUFACTURER.
 Most pellet vent pipe requires a minimum of 1" of clear-
ance to combustible materials although some can be
installed at 1" clearance.
 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” (75 mm) O.D. so the stove
was designed to accommodate a 3”(8 cm) stove pipe adaptor but
the diameters of the pipes depends on the type of installation.
Your installation may require the use of 4” (10 cm) vent as shown
in the table.

a Losses in pressure associated with a 90° elbow can be
compared to those incurred by 4' (1.2 m) pipe. An in-
spectable union-tee can be considered equivalent to a
90° bend.
For example : if installing a section greater than 20’ (6 m) in length
with 3” (8 cm) diameter pipe, calculate the maximum usable length
in the following ways:
- If a maximum of three 90° elbows are used, the maximum
length of the section will be 25’ (8 m).
- If a maximum of two 90° elbows are used and bearing in mind
that a 90° bend can be replaced by 3’ (1 m) of pipe, the maxi-
mum length of the section will be 25’(8 m) + 3’(1 m) = 28’(9 m).
- If a maximum of one 90° elbows is used and bearing in mind
that a 90° bend can be replaced by 3’ (1 m) of pipe, the maxi-
mum length of the section will be 25’ (8 m) + 3’ (1 m) + 3’ (1 m)
= 31’ (10 m).
Where 4” (10 cm) diameter pipe must be used, connect it to the
stove flue outlet with a union-tee.

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.
a Gruppo Piazzetta S.r.l. 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

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:
- General vent layout is shown in figure and the procedure is as
follows: !da duplicazione!
- 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”(40 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”
(40 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” (30 cm) above the roof line and
terminate with a PL listed Rain Cap. If the Vent extends more
than 6’(2 m) above the roof penetration, Roof Brace Poles and a
Roof Brace Band must be used to provide lateral support. In ge-
ographical regions experiencing sustained low ambient tem-
perature is recommended to enclose exterior vents below the
roof line. This help reduce condensation, soot accumulation,
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.
Using this kind of installation the pellet stove is able to draft nat-
urally without exhaust blower operation (failure), reducing the
probability of burn-back and back-drafting.
a Check that the connection to the flueway is gas/smoke-
tight, since the appliance operates in a vacuum.
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.

If upon inspection you find that the chimney is not completely
sound, a relining of the chimney with either PL vent or single wall
stainless steel pipe may be necessary to bring the chimney into
compliance. If the existing chimney is wide enough we recom-
mend a pipe with a maximum diameter of 6”(15 cm).
Put attention: some areas require that a liner must be always in-
stalled to the top of the flue, as shown in figure even if the exist-
ing chimney is in compliance.

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 difficult 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
Vent adapter.

When terminating the exhaust system under the houses eaves,
the following requirements shall be fulfilled:
- in selecting locations for appliance and vent, take into con-
sideration the NPFA 211 6-3.5 rule for distance of exit terminal
from window and openings
- run the vent vertically up the wall, ensuring to maintain a mini-
mum of 3” (80 mm) clearance between the wall and vent
- a wall band must be installed just above the tee and at least
every 6’ (180 cm) of vent rise or, if the rise is inferior, at the end
of the vertical run
- after a rise of at least 5’ (1.5 m), install a 90° elbow aimed out
from the building wall
- attach a 45° elbow to the 90° elbow, aiming the second elbow
down toward the ground. Terminate the vent with a collar with
screen fastened to the 45° elbow
- the end of the vent pipe system must be at least 12” (30 cm)
from the wall and 24”(60 cm) below the eave

4.9 MINIMUM FLUE VENT CONFIGURATION
Horizontal installations that terminate without any vertical sec-
tions of pipe are approved; however, it is recommended that a
minimum of 5’ (1.5 m) of vertical be included in the vent system.
Having a vertical section in the venting will help prevent smoke
from exiting the appliance during power failures.
It is required that outside air be installed with this venting con-
figuration to reduce smoke and creosote smell in the room in the
event of power failure.

4.10 VENTING: TERMINATION REQUIREMENTS
In determining optimum vent termination, carefully evaluate ex-
ternal conditions especially when venting directly through a wall.
Since you must deal with odors, gases, and fly ash, consider aes-
thetics, prevailing winds, distances from air inlets and combusti-
bles, location of adjacent structures and any code requirements.
- There is no minimum clearance requirement between exhaust
terminal and fresh air inlet if the exhaust terminal is positioned
above the fresh air inlet.
- Do not terminate vent in any enclosed or semi-enclosed area,
(i.e. Carports, garage, attic crawl space, etc.) or any location that
can build up a concentration of fumes.
- Terminals must not to be recessed into a wall or siding.
- When setting into place flue caps you should consider wind fac-
tors such as dominate wind directions and currents in order to
avoid down draft, fly ash and/or smoke.
a Vent surfaces can get hot enough to cause burns if
touched by children. Non-combustible shielding or
guards may be required.
 Be sure to use approved pellet vent pipe and wall pass-
through fittings to go through combustible materials.
The type of installation must first be considered before determin-
ing the exact location of the venting termination in relation ship
to doors, window, cavities or air vents.
