GENERAL SAFETY RULES
WARNING!!! You can never be too careful: before installation, read and observe these basic
rules:
When installing the stove, the regulations in force for flue gas exhaust must be complied with.
Correct installation and periodic maintenance of the product must be entrusted to a specialist
installer, who will verify efficient chimney draught before and during combustion. (Authorised
technician in accordance with EEC 46/90)
Complete cleaning of the stove and the system must be carried out annually by an authorised
service centre. Failure to do so will result in the product warranty being void.
The stove requires a certain amount of air for combustion, and consequently intake of air from
outside of the room where the stove is installed is required, in addition to a supplementary indirect
air intake of at least 180 cm2.
Given the weight of the stove, before installation it must be verified that the place where it will be
positioned is able to bear such weight.
Place a floor protector underneath the stove if the floor is made from flammable material, e.g.
parquetry or carpet (the protector must protrude at least 25/30 cm on all sides of the stove).
It is advisable for safety reasons to leave a distance of at least 20 cm between the hot sides of the
stove and any flammable coverings, e.g. timber panels, wallpaper, etc., or use specific insulating
materials available on the market. The same rule applies to furniture, chairs, curtains, etc. (distance
of 100 cm at the front).
Do not insert the stove in narrow spaces that have not been specially prepared or lean it against
walls that may prevent correct air flow (at least 3 cm).
Absence of chimney draught (or, for example, obstruction or closing of the burn pot air intake or
the burn pot itself) will alter operation of the stove, and during automatic ignition may cause an
excessive amount of pellets to be fed into the burn pot due to delayed ignition. Excessive smoke in
the combustion chamber may cause the flue gas to self-combust, causing a violent flare; never
open the combustion chamber door in such conditions.
Flammable liquids must never be used to ignite the fire.
Do not touch the glass when the stove is at working temperature, and use caution before touching
it at any time.
Do not allow children to be left alone near the stove when this is on, as all of its hot parts may
cause severe burns.
Do not carry out any work on the stove other than what is needed for normal use or recommended
in this manual to solve minor problems. Always unplug the stove from the power socket before
commencing any work. If it is essential to remove a foreign body that has got stuck, remember to
always unplug the power cable, so as to prevent accidents from occurring due to the stove starting
automatically, if programmed.
Always make sure that the combustion chamber door is tightly closed during ignition and operation
of the stove.
Automatic ignition of the pellets is the most delicate phase, and to ensure this runs smoothly,
always keep the stove and the burn pot clean.

INSTALLATION
The installation position must be chosen according to the surroundings, the flue gas exhaust
and the chimney. Check with local authorities whether there are any restrictive regulations
concerning combustion air intake, air change and the flue gas exhaust system, including the
chimney and chimney pot. The manufacturer declines all liability for installations that do not
comply with the laws in force, incorrect air change, electrical connections not in compliance
with regulations and improper use of the appliance. Installation must be carried out by a
qualified technician, who shall provide the customer a declaration of system conformity, thus
taking complete responsibility for the final installation and consequent correct functioning of
the product. The stove is supplied with a booklet describing the testing and periodic
maintenance to be carried out by the installer.
POSITIONING THE STOVE
The stove should be positioned in the most central point of the room being heated, so as to
ensure uniform distribution of heat and optimum efficiency.
CONNECTION TO THE POWER SUPPLY
1. The stove must be connected to the power supply using an earthed socket, making sure
that the socket is working correctly before plugging the stove in.
2. During installation, make sure that the connection cable is not in contact with hot parts of
the stove and is not crushed, to avoid the risk of short circuits.
NB the stove is protected by fuses fitted in the main switch located at the rear of the stove.
Always remember to switch off the stove before carrying out any maintenance and/or
checks!
CONNECTION TO THE CHIMNEY
Connection of the stove to the chimney/flue is an important operation that can affect correct
operation and must therefore always be carried out and checked by specialist and qualified
personnel. Avoid “DIY” installation of the stove, especially without properly knowing all of the
necessary information.
Before installing, always check that the inside diameter and height of the chimney/flue are
adequate to ensure correct draught and that it is not obstructed or poorly installed.
NB in the section connecting the flue gas pipes to the chimney, no reductions in diameter are
allowed from the outlet provided on the stove; to ensure correct operation, avoid horizontal
sections as these may fill with ash and consequently reduce the available diameter; also avoid
excessive bends (maximum 2), which must be fixed stably, to ensure less pressure drop.

FLUE GAS EXHAUST INSTALLATION
FIG. 1 Installation without masonry chimney.
Flue gas exhaust Ø 80: solution with one 90° bend
The first section, horizontal (flue gas pipe) runs directly to the outside of the building.
The second section, vertical (chimney and chimney pot) is outside of the building.
The outside vertical section must end, as shown, above the roof.
For best stove performance, a greater height is recommended.
FIG. 2 Installation with masonry chimney and outlet above the roof
Flue gas exhaust Ø 80: solution with one 90° bend
The first horizontal section (flue gas pipe) connects to a traditional chimney either inside or
attached to the building. If the chimney is made from masonry or is too large, a steel pipe no
smaller than 80 mm should be inserted. The chimney must end above the ridge of the roof.
COMBUSTION AIR INTAKE INSTALLATION
Both Figures 1 and 2 apply
For all the solutions illustrated, there are two possible alternatives:
1 Take in air directly from the outside through a pipe connected to the fitting provided on the
rear of the stove.
2 Take in air directly from the room where the stove is installed.
In the latter case, near the stove, an air intake measuring at least 180 cm² must be
provided on a wall connecting to the outside.
In both cases, periodically check that nothing is obstructing air flow (protect the air
intake with a suitable grill).
REMEMBER THAT THE FOLLOWING ARE ALWAYS NECESSARY:
Proper air intake
Horizontal sections must have a minimum gradient of 5° and a minimum length of 2 metres
The vertical section must have a minimum height of 2 metres
Sections of flue gas piping must be accessible for inspection
Mastic or high-temperature gaskets should be used to seal the pipe connection to the flue
gas outlet fitting.
A condensate drain and ash collection opening are recommended.
IMPORTANT: never connect chimneys/flues from different stoves, fireplaces, etc. to
each other.

It should be noted that the table is used for new installations and provides general parameters to
guide the installer in correctly defining the chimney/flue diameter so that if not included in the
ranges described above, it must be suitably adapted and calculated, while existing chimneys
must be checked and cleaned where necessary to ensure the best possible draught.
TABLE FOR CALCULATING PELLET STOVE CHIMNEYS

USER AND MAINTENANCE MANUAL
User manual version 11/2009

Height-negative pressure
The negative pressure (draught) of a chimney also depends on its height. The negative
pressure required for the various models of pellet stoves is from 15 pa to 20 pa (0.15 to 0.20
mbars).
FUEL TO BE USED
Pellets are fuel that comes in the form of small cylinders measuring about 6 mm in diameter,
obtained from pressing sawdust and shredded waste wood, without using additives, dyes or
other foreign materials.
Pellet technical specifications:
Diameter 6-6.5 mm
Maximum length 20-25 mm
Maximum moisture content 6%
Heat value approx. 4,800 kcal/kg
The stove is built to burn pellets made from non-resinous wood, preferably beech.
NB the use of pellets with features other than those specified above will reduce stove
efficiency, cause fouling and poor combustion and make it necessary to recalibrate the
combustion parameters, on all versions. The stove is not guaranteed to work properly
with pellets other than the type described above.

STARTING THE HOT-AIR STOVE
Normal operation of the controller installed on the hot-air stove is described below, with
reference to the functions available to the user. The following information refers to the
controller fitted with the timer-thermostat option. The programming procedures are then
analysed the subsequently.
Before switching on the stove, the display will be as shown in the figure
To start the stove:
The stove is switched on manually by pressing and holding P3 (ON/OFF) for a few seconds.
The same button is used to switch the stove off. A complete cycle usually comprises five
distinct phases (ignition, flame stabilisation, normal operation, economy and shutdown), which
alternate depending on the flue gas temperature measured and certain other parameters.
Ignition phase
Ignition starts by pressing and holding P3 (ON/OFF) for a few seconds. The procedure begins
with activation of the glow plug (heater) and continuous feeding of pellets by the screw. The
messages “IGNITION", “PELLET FEED” and “AWAITING FLAME” will be shown on the display
in succession. After about 45 seconds, the gearmotor stops and the flue gas exhaust fan is
activated (at a predefined speed). Once the pellets have ignited and the flue gas temperature
reaches 50°C, the glow plug switches off and the flame is stabilised. The ignition phase ends
when a temperature of 65°C is reached, however for safety reasons and to safeguard the glow
plug, there is a maximum time of 15 minutes, after which if the pellets do not ignite, the display
will show the “FAILED IGNITION” alarm.

USER AND MAINTENANCE MANUAL
User manual version 11/2009
20
Flame stabilisation phase
In this phase the feed screw loads the pellets at a predefined speed. When the flue gas
temperature exceeds 50°C, the stove enters flame stabilisation mode. In the flame
stabilisation phase, the flue gas exhaust fan works at the set speed, and the temperature
remains stable for a certain time, after which it goes into “OPERATING” mode.
Normal operation
The board features an input for an external thermostat. The stove will operate depending on
the external thermostat and room thermostat settings and the room temperature measured:
T room : room temperature measured by the probe
T setRoom : room temperature set on the external thermostat
T setTherm : room temperature set for the SET ROOM TEMP parameter
External thermostat closed (Troom > TsetTherm): The message “ton” is shown on the display
and the stove operates at the set output level, until the thermostat contact opens.
External thermostat open (Troom > TsetTherm): The stove operates at the set output level
until reaching TsetTherm (Troom < TsetTherm), after which it switches to economy mode.
Modulating operation will begin if the room temperature reaches the “SET TEMPERATURE”
value. During this phase, the feed screw and the flue gas exhaust and heat exchanger fans
work at minimum speed, and the message “MODULATION” is shown on the display.
