Make sure that the room has requirements and characteristics comply with the standards in force.
Also make sure that the oor of the room is suitable to support the weight of the boiler.
E ‘must also drain into the room at least as much air as is required for a normal combustion: you have to practice then,
in the walls of the room, the openings with a free section of at least 6 cm2 per 1 kW (859.64 kcal / h ).
The minimum section of the opening must not be lower than 100 cm2.
The section can be calculated using the following relationship:
S = K * Q ≥ 100 cm2, where “S” is expressed in cm2, “Q” in kW, the “K” = 6 cm2 / kW
These openings must be protected by grates, metal mesh or other suitable protection provided does not reduce the
minimum section, and positioned so as to avoid them being obstructed.
The air ow can also be obtained from a room adjacent to the installation provided that the ow can occur freely
through permanent openings communicating with the non-reclosable outer. The air ow must be smooth and clean air,
unpolluted, and not taken from outlets that may be contaminated (example: garage)

Connection to the ue 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 6 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 ue 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 6 Pa and 10 Pa.
Connection to the ue 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 6 Pa and 10 Pa. At the botton of the ue pipe, provide

This kit comprises:
- a plate heat exchanger
- a three-way diverter valve
- water ow switch
- pipes and unions for connection
The kit is preassembled by the manufacturer’s task is
to heat the domestic water from the water line of the
dwelling. In the moment in which there is request for
opening a hot water tap, the ow switch commands
the diverter valve to convey the hot water contained
inside of the boiler towards the plate heat exchanger.
In the case in which the heater is turned off and there
is demand for sanitary water, the heater after 30
seconds from the request, it automatically starts the
ignition process to heat the water inside the boiler
and then to heat the sanitary water.
Directions for use
If the installation of the boiler 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 boiler using
hoses so that the boiler is not too strictly connected
to the system, and to allow slight movement.
These are as helpful as the supply and return piping
system if the heating system is on a higher oor than
the boiler.
The exhaust pipe pressure is connected temporarily to
a carafe or a funnel to avoid, in case of overpressure,
that the water gush bathrooms and the structure and
the oor.

Replenishment of the System
The replenishment has to be slowly carried out
in order to let the air bubbles ow out through
the right oulets that are placed on the heating
system.
In heating systems with a closed circuit the
loading cold pressure of the system and the
ination pressure of the expanding vase must
correspond.
• in heating systems with open vase, the direct
contact between the circulating liquid and the air
is allowed. During the heating-season the user
must regularly check the circulating water level
in the expansion vase.The content of water in
the system of recirculation must be stable hold.
Experiences show that the user must regularly
check the water level every 14 days in order to
maintain a stable water content.
The replenishment process must be carried out
in case of necessity of more water when the
boiler has cooled down.
These preventive measures aim to prevent the
insurgence of thermic stress of the steel body of
The lling pressure of the system when cold
must be 1 bar. During operation, if the system
pressure drops (due to evaporation of dissolved
gases in the water) to values lower than the
minimum indicated above, the user must use
the lling tap to bring the pressure back up to its
normal pressure.
For proper operation of the boiler when hot, the
pressure in the boiler must be 1,1 bar.
the boiler.
• in systems with open vase, the pressure of
water in boiler, when the system is cold, mustn’t
be lower than 0,3 bar;
• the water used to ll up the heating system
must be decontaminate and without air.
The loading valve is required and must be
provided in the hydraulic system.
This operation must be carried out with caution
following these steps:
• open the vent’s valve of the radiator ,of the
boiler and the system;
• Gradually open the lling tap of the system
checking that the automatic vent’s valves,
placed on the system, are regularly working;
• Close the vent’s valves of the radiators as
soon as the air ows out;
• check through the pressure gauge placed in
the system that the pressure is reaching 1 bar
(this is required only for systems with closed
vase, you have to look for local rules that allow
it); whereas for systems with open vase the
restoration will be automatic;
• Close the lling tap of the system and then let
the air ow out again through the vent’s valve
of the radiator;
Filling the thermostove funding of sanitary kit
Once all the water connections, proceed to
check pressure seal by lling the boiler. During
this operation, any air in the system is released
from the automatic vent valve.
You must not mix water of the heating
system with antifreeze or anticorrosion
substances in wrong concentrations.
This could ruin the seals and provoke the
insurgence of noises while operating.
The producer refuses any responsibility for
damages towards persons, animals or things if
this warning will not be respected.

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.

The pellets are cylinders of compressed wood, produced from sawdust and wood
processing (chips and sawdust), generally produced by sawmills and carpenters.
The binding capacity of the lignin contained in wood, allows to obtain a compact
product without adding additives and foreign chemicals to the wood, is
therefore obtained a natural fuel with high yield. The use of expired
pellets or any other unsuitable material can damage parts of the
boiler and impair proper operation: this can lead to the termination
of the guarantee, and its producer responsibility.
For our boilers use pellets diameter 6 mm, length 30 mm
and a maximum of 6% moisture. Store the pellets away from heat
sources and not in humid environments or with explosive atmospheres.

Confi guration 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.
