pag. 15
INSTALLATION
4.3.1 DESCRIPTION OF THE AUTOMATIC MODE CYCLE
When the letter A appears on the display it indicates that the Automatic cycle has been selected. In the Automatic cycle the
appliance expresses its maximum operating flexibility by optimizing the fuel consumption. If, for example, the temperature
is set (7) at 70 °C the five speed ratios will be automatically distributed between 61 and 70°C so that when the temperature
reaches 70°C the appliance will be running at the minimum power. The level at which the minimum is reached can be
changed by means of button (2). If the value of the button (2) is increased or reduced all the power steps will be redistributed
in the temperature scale.
Consequently, we recommend you find the appropriate level at which the SET POINT minimum is reached in order to
optimize the heat produced by your heater.
If, for example, the SET POINT is set at a high temperature such as 73°C the appliance will attempt to go to that level in
the shortest time possible by modulating the power as it approaches the set temperature. There is no point in setting high set
point temperatures when the conditions of the environment do not require them. With time and experience you will learn
which set points are best for your particular needs.
If the combustion power is not absorbed by the plant above 76 °C, the appliance will shut off temporarily and STOP appears
on the display (6). The heater starts up again at 74 °C.
4.3.2 DESCRIPTION OF THE MANUAL MODE CYCLE
When the plant is operating in manual mode the letter A disappears from the display. The power expressed in this cycle
remains constant independently from the power absorbed by the plant. The plant pump is always activated at anticondensation
temperatures, that is above 61 °C. In this case as well, it is possible to set a set point temperature above which the appliance
will run at minimum power. If an overly-high power level for plant absorption is set, above 75 °C the appliance will shut off
temporarily and the word STOP appears on the display (6). The heater will automatically restart at a temperature of 74°C.

4.4 CONTROL, ADJUSTMENT AND PROGRAMMING FUNCTIONS OF THE H20/COMPACT
CONTROL PANEL
4.4.1 SETTING THE OPERATING PROGRAMS P1 AND P2
Your appliance is provided with an excellent operating program to enhance combustion efficiency. The particular
configuration of the burner keeps the area where the pellets drop and burn clean for many hours. However, if you wish to
keep the burner even cleaner simply select the P2 operating cycle which emits a larger quantity of air into the brazier. This
operating program accelerates the smoke exhaust even further and consequently when you select it you know there will be
a loss in combustion efficiency. The fuel consumption is not affected. Use the following procedure to select the P2 operating
cycle:
Switch off the appliance by turning the rear selector switch to “0”.
Press and hold down the button ( 2 )( see par 4.3), then re-power the appliance by turning the selector switch to 1.
The text P2 appears on the display to indicate that the cycle has been selected; at that point release the button (2).
The appliance will retain the P2 setting even if the electrical power supply is cut off.
To return to the P1 setting carry out the above operations, that is:
Switch off the appliance by turning the rear selector switch to “0”.
Press and hold down the button ( 2 ), then re-power the appliance by turning the selector switch to 1.
The text P1 appears on the display to indicate that the cycle has been selected; at that point release the button (2).
The appliance will retain the P1 setting even if the electrical power supply is cut off.
The consumption of the appliance remains the same for the two power levels P1 and P2.
4.4.2 SETTING THE TIME AND DATE
To access the current time and date setting menu the appliance must be in OFF mode. See the drawing below.
Hold down the button and press the button until the graphic image shown below appears on the display.
Press the button to set the current day (e.g. Monday). Then press the button to confirm. The following
graphic image will appear on the display:

Press the button to set the current hour (e.g. 10). Then press the button to confirm.
The following graphic image will appear on the display:
Press the button to set the minutes (e.g. 10:35). Then press the button to confirm and quit the current time
and day setting menu. The following graphic image will appear on the display.
4.4.3 CONTROLLING THE PRESSURE OF THE WATER IN THE BOILER
The appliance is equipped with a pressure transducer for controlling the amount of water and pressure in the hydraulic
circuit.
To view the pressure inside the boiler press the button . The value of the steam pressure (expressed in bars) detected
by the sensor appears on the display for a few moments; see the figure illustrated below.
If the circuit pressure drops to values which are too low caused, for example, by fluid leaks from tubing or other areas the
pressure transducer detects that the pressure is too low and P H2O appears on the display. In this situation the appliance does
not feed pellets and the smoke exhaust works for a few minutes to discharge any remaining combustion products.
The alarm resets automatically if the pressure returns to a value above 0.3 bar.
The recommended pressure inside the boiler is 0.8 - 1 bar.
The pressure level must remain under 3 bar because if it goes higher than this threshold a safety valve calibrated at 3 bar is
activated and the water is drained out of the circuit (see hydraulic installation diagrams).

4.6 H20/COMPACT ROOM TEMPERATURE THERMOSTAT
The room temperature thermostat is supplied with the appliance. The display A indicates
the temperature set by the user. This value can be changed by means of the controls B and
C. The display D indicates the room temperature detected by the thermostat. The signal is
transmitted by radio waves. The unit is powered by the 220-12V transformer supplied with
the heater. The thermostat may be affixed to a wall (see drawing on the right) or in any
other area as long as it is installed approximately 1.5 metres from the floor, away from heat
sources, windows and any other object which could affect the correct room temperature
value. The thermostat should be installed no further than 10 metres from the appliance
for normal operation. Clean the surfaces thoroughly before fixing the velcro to the them.
The room temperature thermostat detects the temperature and updates it roughly every 30
seconds.
When the room temperature reaches the temperature
set on the thermostat the appliance displays a
blinking black bar indicating the minimum power
level. At that point the power increase operations are disabled. In this phase the
appliance shuts off (according to the manual or automatic cycle previously selected)
if the set point temperature of 76°C is reached in the boiler.
If the power supply to the thermostat or the transmission is cut off, normal operation
restarts from the control panel after 5 minutes.

INSTALLATION
It is furthermore necessary to place the room temperature thermostat at a
maximum of 10 metres from the appliance as if the distance is too great and
there are too many walls located between the room temperature thermostat
and the appliance, this can affect the functioning of the thermostat.
In order for the room temperature thermostat to function correctly it is
important for the “code system” of both the thermostat and the power board
to be set with the same combination. To access the boardʼs “code selection
system” firstly disconnect the power supply, then remove the applianceʼs left
side panel and remove the 2 screws from the power board cover (par. 3.4).
To access the “code selection system” of the room temperature thermostat,
firstly disconnect the power supply, then undo the only 2 screws present on
the thermostat and open the 2 half bearings (see figure above). Our products
are set with a standard code. To change the transmission code simply act on
the selector switch indicated on the top left to change the combination on both
panels, that is the control board and the room temperature thermostat.

5. USE OF THE HEATER/BOILER
5.1 SWITCHING ON THE H20 HEATER/COMPACT BOILER
Before using the appliance check that all the movable parts are in place; also remove any labels and
stickers from the glass to avoid having permanent traces remain on the surfaces.
Ensure that the electrical and hydraulic connections have been made perfectly.
Then carry out the following operations:
- Check that the hydraulic plant has been made correctly, and that the expansion
tank is sufficiently large to guarantee maximum safety. Remember that expansion
is calculated as 6 % of the total volume contained in the plant. Any damage to the
plant and/or the appliance shall not be considered as covered by the warranty. The
installation of the expansion tank in the appliance does not guarantee adequate
protection from the thermal expansion of the water in the plant.
- Connect the electrical power supply to the appliance and turn the rear switch to “1”.
- Fill up the plant by opening the cock Z (figure on right).
- During the replenishment phase do not apply over-pressure to the appliance: max
pressure 1 bar. Read the pressure as explained in paragraph 4.4.3.
- The water filling phase must take place simultaneously with the discharge of air.
Perform the bleeding operation by means of a screwdriver (to accelerate the plant
fill-up times) or a punch on valve 4 (figure on right)
- Connect the smoke outlet to the appliance: we recommend against using aluminium
tubes. Always use sealing gaskets. More details are given in paragraph 8.2 of this
use and maintenance booklet.
- Load the pellets into the tank.
- Press the “A” button to start the start up cycle, which is confirmed by the word
START appearing on the display. Press the same button once again to set the
combustion power level. Press the “B” button to adjust the set point temperature
for the water in the boiler (see par. 4.3). In the 20 minutes required for start up any
thermal power level set by the user is ignored in order to meet the correct loading
and suction values which have been preset by the Manufacturer. The pellets do
not drop into the burner the first time the appliance is switched on during the initial phase because the screw feeder is
empty.. As soon as the first few pellets drop into the brazier it could turn off and reset all the black bars. The word OFF
must appear on the display. At this point you can restart the start up phase knowing that it will be successful.
- Check the pressure inside the appliance once again and if required, bleed air bubbles from the special valve.
CAUTION: The start up phase lasts 20 minutes.
CAUTION: The system circulating pump starts as soon as the temperature in the boiler reaches 61°C.
CAUTION: If the appliance does not start up correctly check that the brazier and heating element are clean.
It is extremely important to ensure that the conduit for the heating element is clean; there must be
no scale or dust accumulations. Clean using a strong vacuum cleaner.

5.2.1 Manual adjustment of the combustion (see par. 4.3.2)
5.2.2 Automatic adjustment of the combustion (see par. 4.3.1)
CAUTION: The manufacturer declines all responsibility for the life of the electrical heating element
if subjected to an excessive number of start ups.
Consequently, it is advisable to set the correct power level to avoid such a hazard.
5.3 ADJUSTING THE ROOM THERMOSTAT H2O/COMPACT
See paragraph 4.6 for details on using the thermostat.
6. ADDITIONAL ROOM TEMPERATURE THERMOSTAT
AND CHRONOTHERMOSTAT
Two connectors are installed at the back of the heater near the power socket. These refer to two operating modes which can
also function simultaneously:
- With the additional room temperature thermostat
- With the chronothermostat.
CAUTION DANGER: the contacts on the jacks must
never be powered with 220 V power contacts
6.1 ADDITIONAL ROOM TEMPERATURE THERMOSTAT (NOT SUPPLIED)
An additional room temperature thermostat may be installed, connected to the back of the appliance by means of a jack
inserted into the socket marked «TERMOSTATO/THERMOSTAT». This is a stereo-type jack, and it is supplied with
the heater; the thermostat must be connected to the “X” and “Y” contacts (see figure). The two tin-coated wires must be
connected on the room temperature thermostats to the N.C. terminals (contact normally closed).
The operating principle is as follows: if during operation the thermostat contact closes, the combustion power turns
automatically to the minimum power level. The situation is indicated by the blinking of the 1st power bar on the display.
It is possible to install it together with the room temperature thermostat supplied with the appliance.
CAUTION: The contacts to be used for the connection to the additional room temperature thermostat
must be the N.C. type mod. “Perry “ contacts 1-2
6.2 ADDITIONAL CHRONOTHERMOSTAT (NOT SUPPLIED)
As an alternative to the additional room temperature thermostat it is possible to install an additional chronothermostat, by
connecting it to the back of the appliance, by means of a jack inserted into the socket marked «CRONOTERMOSTATO/
CHRONOTHERMOSTAT». This is a stereo-type jack, and it is supplied with the heater. The chronothermostat must be
connected to the “X” and “Y” contacts (see figure above). The operating principle is as follows: when the contact closes the
appliance starts up in automatic mode whereas when the contact is opened the appliance shuts off. An N.O. contact must
be used, that is normally open. When the chronothermostat is active, the appliance cannot be switched off except by means
of the additional chronothermostat.
CAUTION: N.O. type contacts must be used for the connection to the additional chronothermostat.
Contact 1 - 3 mod. “Perry “.

7.3 PATENDED SELF-CLEANING BURNER (NR. VI2004A000014)
The H2O heater/Compact boiler is fitted with a
state of the art patented burner which manages
to guarantee high performance with optimal
automatic cleanliness of the burner due to the
special applied technology. The combustion
generates the division of the flame into 2 fronts:
this guarantees optimal use of the firebox walls,
which have never been used to advantage in other
pellet appliances. Manual cleaning of the heater
is reduced to a minimum.
Disassemble procedure:
- Remove blade 1 .
- Open the closure springs 6.
- Move away chutes 2 and 3 .
- Remove the arm 4 and bearing 5.
- Remove the screws (8) and pull out the brazier
To reassemble, reverse the above process.
In the OFF mode the left-right movement of
the cast iron blade 4 for cleaning the brazier
is set at roughly 10 mins.
It is normal to find partially burned embers on
the sides of the burner.

8. SMOKE VENT AND COMBUSTION AIR SUCTION
Because of frequent accidents caused by poor functioning of the smoke outlets in normal houses, we have prepared the
following paragraph to assist the installer in checking all the parts related to eliminating smoke produced by the combustion
process. The smoke outlet must comply with UNI 7129/92 in observance of the following reference values.
8.1 VENTILATION OF THE ROOMS
• The room where the heater is installed must have a good air flow to guarantee secondary air for the appliance for the
combustion process and for ventilation of the room. The natural air flow occurs directly through permanent apertures to
the outside made in the walls of the room, or by means of single or multiple ventilation ducting.
The ventilating air must come from outside and if possible, away from sources of pollution. Indirect ventilation is also
allowed by taking in air from rooms adjacent the one where the heater is installed taking into account all the warnings and
limitations specified below.
• The apertures in the walls must comply with the following requirements:
- have an unobstructed section of at least 6 cm2 for each Kw of installed thermal power, with a minimum limit
of 100cm2;
- be made in such a way that the vent openings, both on the inside and outside of the wall, cannot be obstructed;
- be protected with grills or similar systems in order not to reduce the section described above;
- be situated at floor-level.
Page 30
pag. 30
SMOKE VENT AND COMBUSTION AIR SUCTION
• Air used for combustion is sucked in through a tube installed at the back of the appliance. It has a diameter of 80 mm.
• The air flow can also be obtained from an adjacent room as long as:
- the adjacent room is equipped with direct ventilation in compliance with the points described above;
- in the room to be ventilated the installed appliances are only connected to one flue outlet;
- the adjacent room is not used as a bedroom or a common area of the building;
- the adjacent room is not a room with a fire hazard, such as storage sheds, garages, combustible material store rooms, etc...;
- the adjacent room does not become a vacuum compared to the room to be ventilated due to an opposite draught effect;
- the air flow from the adjacent room to the room to be ventilated is unobstructed through the permanent apertures having
an overall net section of no less than that indicated above. These apertures can be obtained by enlarging the space between
the door and the floor.
This chapter is not intended to replace UNI 7129/92 to which it refers. The qualified installer must
in any case be fully aware of this standard and its amending versions.
8.1.1 COMBUSTION AIR SUCTION
The air required for combustion can be taken from the room
in which the heater is installed. However, the room in which
it is installed must be sufficiently ventilated (1300 m3/h) (see
par. 4.1).
If you prefer to use air directly from outside simply follow the
diagram illustrated on the right.
- Remove the 2 self-tapping screws
- Remove the cover
- Move the suction tube to the limits given on the right.
- Be protected with grills or similar systems in order not to
reduce the section described above;
- Be situated at floor-level.

SMOKE VENT AND COMBUSTION AIR SUCTION
8.2 SMOKE OUTLET
The smoke outlet shown in the following figures is the best solution to ensure the discharge of smoke even when the fan
is not operational, such as for example if there is an electrical power failure. A minimum drop of 1.5 metres is required
between the T terminal on the outside of the building and the outlet at the back of the appliance, to ensure that residual
combustion smoke is discharged in the case described above (Otherwise the residues would stagnate inside the firebox and
be discharged out to the free atmosphere).
The figures below illustrate the best solution for discharging the smoke out through the roof or into the flue outlet. If you
opt to discharge the smoke out through the roof it is important to operate as shown in the figure below on the left. The
smoke outlet tubes, given the low temperature of the gases, must be insulated. We recommend installing a “T” condensation
collector. Insert a union tee with inspection cap, connecting brackets suitable for the height of the flue outlet, flashing that
crosses the roof and chimney cap to protect against bad weather conditions. If you decide to use a classic masonry outlet
see the diagram below on the right. A union tee with inspection cap and suitable supporting brackets are required. If the
flue outlet is too big we recommend inserting a stainless steel or porcelain-coated steel tube with a diameter not exceeding
150mm. Seal area where the inlet and outlet part of the smoke exhaust meets the wall.
It is strictly forbidden to apply mesh to the end of the outlet tube , as it
could cause the appliance to malfunction. If the smoke tube is installed
in a fixed position it is advisable to provide inspection openings for
clean-out purposes especially in the horizontal sections. See the
diagram. These openings are essential to allow for the removal
of ash and unburned products which tend to accumulate along the
discharge path. The appliance functions with the firebox in a vacuum,
while the discharge of smoke to the flue outlet has a slight pressure,
consequently it is imperative to ensure that the discharge system is
hermetically sealed. The smoke discharge tube must be made from
suitable materials such as for example:
porcelain-coated steel tubes, and the various fittings sealed with red
silicone (resistant to 350°C). The outer casing of the tube must be
made with insulating material (mineral wool, ceramic fiber) or use
pre-insulated tubing.
It must be possible to inspect and remove all the smoke tube sections for clean-out purposes.
CAUTION: IF THE SMOKE FLUE IS NOT SUFFICIENTLY INSULATED AND/OR IT IS TOO LONG
IT COULD GENERATE CONDENSATION: IT IS ADVISABLE TO INSTALL A CONDENSATION
OUTLET NEAR THE APPLIANCE OUTLET.

INFORMATION FOR THE SKILLED TECHNICIAN
9. INFORMATION FOR THE SKILLED TECHNICIAN
9.1 MAIN COMPONENTS AND THEIR OPERATION
SAFETY THERMOSTAT WITH MANUAL RESET: if the temperature exceeds 100°C the pellet feed screw is shut off.
A red light at the back of the appliance comes on. Once the reasons for the appliance exceeding the upper temperature limit
have been discovered and solved the heater can be reactivated by unscrewing the plastic cover of the thermostat installed
on the back and pressing the button (the temperature of the boiler must be below 73°C).
SAFETY VALVE 3/4” CALIBRATED AT 3 BAR: once the calibrated pressure is reached, the valve opens and discharges
to the free atmosphere (we recommend connecting this valve to an outlet to prevent damage to the material around the
appliance if it is activated) to prevent the pressure in the system from reaching dangerous levels for the generator and the
components of the system. If the valve is activated check and solve the problems which led to the overpressure.
EXPANSION TANK 8 LITRES: This is a safety device installed in the appliance which is used to compensate for the
increased volume of the water in the boiler due to the increase in temperature in the boiler .
SMOKE PRESSURE SWITCH: This is a safety device which, if necessary, shuts down the feed screw motor. The
main reason for the tripping of the pressure switch is the obstruction of the smoke flue or the smoke discharge tube. For
this reason it is strictly prohibited to install a mesh at the end of the tube. When the mesh clogs up it creates a plug which
activates the pressure switch which in turn, shuts off the fuel feed.
SMOKE EXHAUST: This is activated when the start up signal is given. In the first two minutes it «washes» the smoke
discharge tube, that is, it functions at maximum working rate. Once this time has elapsed it self-adjusts to the optimal
speed. To allow for the evacuation of the smoke and for greater safety of the system, the exhaust continues to operate for
approximately 20 minutes from the time the appliance is switched off.
SYSTEM CIRCULATING PLANT: This is a device which makes it possible to convey the hot water produced by the
appliance to the radiators, boiler tubes .....
When it is activated the symbol indicated in paragraph 4.3 appears on the display.
BURNER CLEANING MOTOR: This device makes it possible to create, inside the burner, a continual movement of the
pellets in combustion and a subsequent self-cleaning of the burner.
GLOW PLUG: is activated in the START phase. Heats the air to 800°C, which assist the first combustion of the pellets
present in the brazier.
LOADING MOTOR: This is activated at regular on/off intervals controlled by a microprocessor. The functionality of this
motor is reduced if:
-the motorʼs overload relay is tripped.
-the pressure switch is activated due to obstruction of the smoke discharge tube .
-end of pellet load.
-appliance switched off intentionally
PRESSURE TRANSDUCER: This device detects the water pressure in the system. The value can be checked by acting
on the control panel as indicated in paragraph 4.4.2.
AUTOMATIC RELIEF VALVE: This valve eliminates, without the need for manual action, the residues from the air
inside the appliance thereby preventing:
-corrosive processes due to presence of oxygen.
- noise generated by the flow of air in the tubes.
-air pockets located in the heating bodies.
-cavitation in the circulating pumps.

9.2 TROUBLESHOOTING
9.3 USEFUL ADVICE FOR INSTALLATION AND OPERATION
Useful advice:
1 - The appliance must never be deliberately disconnected from the electric power supply. Whenever the appliance is
deliberately disconnected from the electric power supply smoke could be emitted into the room and be a hazard.
Similarly never switch off the heater by suddenly cutting off the electric power supply.
2 - Do not install the appliance with horizontal wall outlets only: evacuation of the combustion products must be guaranteed
in a natural manner.
3 - Do not install the appliance with horizontal sections only: the wall could be exposed to high wind conditions and the
heater could shut down due to back draft.
4 - Operate the appliance at maximum for 3 hours for a complete drying and baking of the silicates contained in the
enamel which covers the body of the heater.
5 - Do not install a grill or outlet terminal which could restrain the flow of the combustion gases: this could affect the
dynamic gas to the point where it would not allow the pellets to burn correctly.
6 - Read this instruction booklet.
7 - Keep the appliance clean and check the burner as described in this manual.
8 - Clean the smoke outlet regularly.
9 - Use top quality pellets: by saving 20 cents a bag you heat up to 50% less.
10 - Maximum useable lengths of smoke exhaust tubes:
Painted aluminized steel tubes (1.5 mm minimum thickness), Aisi 316 stainless steel tubes or 0.5 mm enamelled tubes
may be used.
Legally compliant smooth internal double-walled flexible stainless steel tubing with male-female collar couplings can
also be used. – Minimum vertical length 2 m – Maximum vertical length 8 m
Length with minimum slope of 5 % 0.5 m – Maximum number of elbows at least 0.5 m apart: 3
