Safety information

Please carefully read this use and maintenance manual

before installing and operating the stove!

If clarication is needed, please contact the dealer or the

Authorized Assistance Center.

• The pellet stove must only be operated in living envi-

ronments. This stove, being controlled by an electronic

board, permits a completely automatic and controlled

combustion; the exchange, in fact, regulates the lighting

phase, 5 power levels and the shut down stage, guaran-

teeing the safe operation of the stove.

• The basket used for combustion allows most of the ash

produced by the combustion of the pellets to fall into

the collection compartment. Nevertheless, check the

basket daily, given that not all pellets have high qual-

ity standards (use only quality pellets recommended by

the manufacturer).

responsibility, both civil and penal, for accidents deriving

from the partial or total lack of observance of the instruc-

tions contained herein.

We decline every responsibility derived from improper

use of the stove, from incorrect use by the user, from un-

authorized modications and/or repairs, from the use of

replacement parts that are not original for this model.

The manufacturer declines every civil or penal, direct or

indirect responsibility due to:

• Lack of maintenance;

• Failure to observe the instructions contained in the

es, glass, handle and tubes become very hot:

during operation do not touch these parts with-

out adequate protection;

• Keep the fuel and other inﬂammable materials

off the thermostove.

Charge pellet

Fuel is loaded from the upper part of the stove by opening

a door.

Pour the pellets in the hopper; vacuum contains about

42 kg of pellets.

This is easier if performed in two steps:

• Pour half of the contents of the bag into the hopper and

wait for the fuel to settle on the bottom.

• Then pour in the second half;

• Keep the cover closed , after loading the pellets , the lid

of the fuel tank;

The thermostove is a product by heating, presents the

external surfaces particularly hot. For this reason, we

recommend extreme caution when operating in particular:

• Do not touch the stove body and the various components,

do not approach the door , it could cause burns;

• Do not touch the exhaust fumes;

• Do not perform any type of cleaning;

• Do not dump the ashes;

• Do not open the ash tray;

sible or after having received instructions relating to the

safe use of the device and to the understanding of the

dangers inherent to it. Children should not play with the

device. Cleaning and maintenance to be performed by the

user should not be made by children without supervision;

• Do not use the thermostove as a ladder or scaffold;

• Do not put clothes to dry on the thermostove.

Any clothes hangers and suchlike must be kept a suitable

distance from the stove. - Risk of re

• Carefully explain that the thermostove is made from ma-

terial subjected to high temperatures for the elderly , the

disabled, and in particular for all children, keeping them

away from the thermostove during operation

• Do not touch the thermostove with wet hands: the ther-

mostove has electrical components that could produce

sparks if handled incorrectly.

• Never open the glass door of the pellet stove while the

thermostove is in operation.

• The thermostove must be connected to an electrical

system equipped with an earthing conductor in accord-

ance with regulations 73/23 and 93/98 EEC;

• The system must be of adequate electrical power de-

clared the thermostove;

• Do not wash the inside of the thermostove with water.

The water could damage the electrical insulation, causing

electric shock;

• Do not expose your body to hot air for a long time. Do

of pellets touch any hot surfaces.

Instructions for safe and efﬁcient use

Operating area

For proper functioning and a good temperature distribution,

the stove shoul be positioned in a location where it is able

to take in the air necessary for combustion of the pellet

(about 40 m3/h must be available), as laid down in the

standard governing the installation and in accordance with

local national standards.

The volume of the room must not be less than 30 m3.

The air must come in through permanent openings made

in walls (in proximity to the stove) which give onto the

outside, with a minimum cross-section area of 100 cm2.

These openings must be made in such a way that it is not

possible for then to be obstructed in any way. Alternatively,

the air can be taken from rooms adjacent to the one which

needs ventilating, as long as they are provided with an air

intake from the outside, and are not used as bedrooms or

bathrooms, and provided there is no re risk such as there

is for example in garages, woodsheds, and storerooms,

with particular reference to what is laid down in current

standards.

It is not permissible to install the ther-

mostove in bedrooms, bathrooms, or in a

room where another heating appliance is

installed (ﬁreplace, stove etc.) which does not have

its own independent air intake.

Locating the thermostove in a room with an explo-

sive atmosphere is prohibited.

The ﬂoor of the room where the thermostove is

to be installed must be strong enough to take its

weight. If walls are ﬂammable, maintain a minimum

distance of 10 cm at the rear (A), of 40 cm at the

side (B) and 100 cm at the front.

If the room contains objects which are believed to

be particularly delicate, such as drapes, sofas and

other furniture, their distance from the thermostove

should be considerably increased.

40 cm

Min.

100 cm2

Connection to the external air intake

It is essential that at least as much air must be able to

ow into the room where the thermostove is installed as

is required for proper combustion in the appliance and for

the ventilation of the room.

This can be effected by means of permanent openings in

the walls of the room to be ventilated, which give onto the

outside, or by single or collective ventilation ducts.

For this purpose, on the external wall near the thermostove,

a hole must be made with a minimum free cross-section

of 100 cm2. (equivalent to a round hole of 12 cm diameter

or a square hole 10x10 cm) protected by a grille on the

inside and the outside.

The air intake must also: communicate directly with the

room where the thermostove is installed be protected by

a grille, metal mesh or suitable guard, as long as this does

not reduce the area below the minimum.

Be positioned in such a way as to be impossible to

obstruct.

In the presence of wood ﬂoors, install a

ﬂoor protection surface in compliance

with the rules in force in the country

Connection to the ﬂue pipe

The ue pipe must have internal dimensions not larger

than 20x20 cm, or diameter 20 cm. In the event of larger

dimensions, or of the ue pipe being in poor condition ( for

example cracks, poor insulation, etc.), it is advisable to t

a stainless steel pipe of suitable diameter inside the ue

pipe throughout its length, right up to the top.

Check with suitable instruments that there is a draught

between 5 Pa and 10 Pa. This type of connection ensures

the evacuation of the fumes even in the event of a

temporary power cut.

At the bottom of the ue pipe, provide an inspection cap

to allow periodic checking and cleaning, which must be

done annually. Make a gas-tight connection to the ue

pipe, using pipes and connectors as recommended by us.

You must ensure that a windproof cowl should be tted

which complies with the standards in force

Connection to an external ﬂue with insulated or

double-wall pipe

The only type of pipe which is permissible is insulated

(double-walled) stainless steel, smooth on the inside,

xed to the wall. Flexible stainless steel pipe must not be

used. At the bottom of the ue pipe, provide an inspection

cap to allow periodic checking and cleaning, which must

be done annually. Make a gas-tight connection to the ue

pipe, using pipes and connectors as recommended by us.

You must ensure that a windproof cowl should be tted

which complies with the standards in force.

Check with suitable instruments that there is a draught

between 5 Pa and 10 Pa.

Connection to the ﬂue pipe

For proper functioning, the connecting pipe between the

stove and the chimney or ue duct must have a slope of

not less than 3% in the horizontal stretches, the length of

which must not exceed 2 metres and the vertical distance

between one tee connector and another (change of

direction) must not be less than 1,5 m.

Check with suitable instruments that there is a draught

between 5 Pa and 10 Pa. At the botton of the ue pipe,

provide an inspection cap to allow periodic checking and

cleaning, which must be done annually.

Make a gas-tight connection to the ue pipe, using pipes

and connectors as recommended by us. You must ensure

that a windproof cowl should be tted which complies

with the standards in force. Fig. 3: connection to an

external ue with insulated

or double-wall pipe.

Fig. 2: connection to the

ue pipe.

Fireplace ﬂue gas

Avoid contact with combustible materials (example:

wooden beams) and in any case provide for their insulation

with ame retardant material. In case of pipe penetrations

through roofs or walls is recommended to use special

kits crossing, certicates, are available commercially. In

the event of a chimney re, turn off the stove, disconnect

from the network and never open the door. Then call the

authorities.

The chimney cap

The chimney cap must respect the following requirements:

• It must have the equivalent diameter and internal form

of the ue.

• It must have a useful outlet diameter of not less than

double that of the ue.

• The chimney cap on the roof or that remains in contact

with the outside (for example, in case of open lofts or

attics), must be covered with elements in brick or tile

and must, in any case, be well insulated.

• It must be constructed to prevent rain, snow, and

extraneous bodies from entering the ue and so that

the discharge of the products of combustion is not

inhibited by wind from any quarter or strength (wind-

proof chimney cap).

• The chimney cap must be positioned in such a way as

to guarantee the adequate dispersion and dilution of the

products of combustion and in any case, must be out of

the reux zone. This zone has different dimensions and

forms according to the angle of inclination of the roof so

it is necessary to adopt minimum heights (Fig. 2).

• The chimney cap must be a wind-proof type and must

be above the ridge.

• Eventual structures or other obstacles that are higher

than the chimney cap must not be too close to the

chimney cap itself.

The pressure relief valve (C) must always be connected

to a water drain pipe. The tube must be capable of

withstanding high temperature and pressure.

Directions for use

If the installation of the thermostove provides interaction

with another existing system complete with a heater

(gas boiler, gas boiler, oil boiler, etc..) consult qualied

personnel who can then answer the compliance of the

system, as envisaged by the law in force.

Flushing the system

In accordance with the UNI-CTI 8065 is strongly

recommended to wash the entire system before

connecting it in order to get rid of residues and

deposits. After ushing the system to protect it against

corrosion and deposits, it is recommended the use of

inhibitors.

Upstream from the stove, always install shutters so as

to disconnect it from the plumbing system should it be

necessary to move it, or when it requires routine and/or

special maintenance. Connect the stove using hoses so

that the stove is not too strictly connected to the system,

and to allow slighht movement.

Plumbing system connection

There are 2 different types of systems:

- Closed vessel system

- Open vessel system.

Closed vessel system

This product has been designed and built to work with

closed vessel systems. In general, the closed vessel sys-

tem has the following expansion as the expansion ves-

sel pre-loaded. In addition to the expansion device, the

closed vessel system must be provided in accordance

with current Italian UNI 10412-2 (2009) by:

•safety valve

•thermostat control of the circulator

•device alarm sounds

• temperature Indicator

•pressure indicator

•audio alarm

•automatic adjustment

•safety thermostat with manual reset

•circulation system

The connection of the stove to the plumb-

ing system must be made ONLY by spe-

cialized personnel who are capable of car-

rying out installation properly, in compliance with

current standards in the country of installation.

The manufacturer will not be held responsible for

damage to persons or things in the event of failed

operation if the aforementioned warning is not

complied with.

DELIVERY

Filling of the system

Filling must be done slowly in order to allow the air bub-

bles to come out through the appropriate vents placed on

the heating system.

In Thermal systems with closed circulation the loading

pressure with cold boiler and the preloading pressure of

the expansion vessel must be equivalent.

• In Thermal systems with open circulation, it is possi-

ble the direct contact between the circulating liquid and

the air. During the heating season, the user must regularly

check the level of water circulating in the expansion tank.

The content of water in the recirculation system must be

kept constant.

Practical experience shows that a regular check of the

water level should be made every 14 days in order to

maintain a fairly constant water content.

In case it is necessary additional water it is necessary to

be made the lling process when the heater is cooled to

room temperature.

These are precautions to prevent the arising of thermal

stress of the steel body of the heating stove.

• In plants equipped with open vessel the water pressure

in the heating stove, (when the system is cold) , must not

be less than 0.3 bar;

• the water used for lling the heating system must be

decontaminated and without air.

When all the hydraulic connections are done, proceed to

test the pressure of the seals, through the lling of the

heating stove.

The loading valve is necessary and must be provided

in the hydraulic system.

This operation must be done with caution, respecting the

following steps:

• open the air vent valves, the heater and the plant;

• open gradually the system ller tap, checking that all

automatic purging air valves installed, are operating prop-

erly;

• close the radiators venting valves as soon as water

ows;

• check on the manometer placed on the system that the

pressure reaches about 1 bar (applies only to systems

with a closed vessel, to consult any local regulations or

standards that allows it); for open vessel, the reintegration

is automatic through the vessel itself;

• close the system ller cock and again release the air

through the vent valves of the radiators;

Do not mix the heating water with

antifreeze or corrosion substances in the

wrong concentrations.

It can damage the seals and cause the occurrence

of noise during operation. The manufacturer

declines all responsibilities if damage caused

to people, animals or property caused if above

instructions are not followed.

Water Characteristics

The characteristics of the water used to ll the system are

very important to prevent the build-up of mineral salts and

the formation of incrustations along the pipes, in the boiler

and in the heat exchangers.

Therefore, please get your plumber’s advice concering:

• Hardness of water circulating in the system, to prevent

problems of incrustation and limescale, especially in the

domestic water heat exchanger (>25° French).

• Installation of a water softener (if water hardness >25°

French).

• Filling the system with treated water (demineralised).

If you have very extensive system, with a large amount of

water, or which require frequent relling, it is recommended

the installation of water softening system. It ‘should

be noted that the encrustations drastically reduce

performance because of their low thermal conductivity.

freshwater (0-12)

water medium (12-20)

hard water (20 - 30)

very hard water (over 30)

To guarantee the results of the certications (see technical table) it is necessary to have the same laboratory conditions

and to install the same parameters of the performance tests.

Only authorized technicians have these parameters and they will be able to install only after having veried that the

conditions of draft of the ue and of the combustion oxygen are the same of those of the tests.

Conﬁguration of the hydraulic diagram of the boiler

BY A SPECIALIZED TECHNICIAN

Before starting the boiler, it is necessary to congure the hydraulic scheme on which we want to work.The boiler is set up

to receive the clean contact of an external thermostat (open / closed, the thermostat must not give tension to the back. If

the thermostat carries voltage to the board causing faults, the warranty is void), two temperature probes and a motorized

valve . All these components can be connected via the terminal board on the back of the boiler.

Per il tecnico specializzato:

To congure the hydraulic diagram, press the SET key and then scroll to the “Technical settings” menu with the

power key. PPress the SET key again to enter the menu and enter the access key in possession of only the technician

authorized by the manufacturer. Conrm the password using the set key and the key  of the power go to menu 3

“hydraulic scheme”. Conrm with the SET key and use the and keys to select the required hydraulic scheme

number.

For end user:

It is possible to change the boiler operating principle according to the season by choosing between summer and winter.

To select the season press SET, the season selection will appear on the display.Then press the set key again and select the

season with keys 1 and 2. Once selected, press the ON / OFF key to exit.

The choice of season changes the boiler operation, see next chapter.

Following the principles of operation of the various hydraulic diagrams.

Important considerations:

• healthcare will always have priority

• There are three types of stand-by:

Type 01: the ambient temperature detected by the probe on the board has reached the SET AIR set

Type 02: the water temperature in the boiler has reached the SET H2O set

Type 03: the external thermostat has detected that the desired temperature has been reached and therefore the

contact is open.

In this specic case the boiler behaves as follows:

If the thermostat carries voltage to the card causing faults, the warranty will expire.

To congure the thermostat, simply remove the jumper on the THERM terminal (see the tab on page 16) and connect our

room thermostat, OPERATION BY A SPECIALIZED TECHNICIAN.

How to select the type of Stand-by (OPERATION BY A SPECIALIZED TECHNICIAN):

Press the SET button; press button to go to menu 09. Press the SET button again. Enter the access key and conrm

it by pressing the SET key again. Press the key to go to menu 9-5.

The display will show the different stand-by modes mentioned above, choose the mode using the and keys.

NOTE: The hydraulic scheme 00 is set by default, the WINTER season with stand-by mode 02.

When the stove is switched off manually or by programming, automatic ignitions exit from a stand-by state will not be

possible.

How to enable or disable the stand-by mode:

Press the SET button.With the ., key, go to menu 05 and conrm with the SET key. Use key sto select whether

to enable (ON) or disable (OFF) the boiler stand-by function.

Press the ON / OFF button to exit

Let’s see specically the behavior of the boiler according to the hydraulic scheme, the presence and the

stand-by mode and the chosen season
