CAUTION:Always use trolleys to move the appliance and the appliance
must always be in a vertical position. The casing for the H2O is packed
separately. On the contrary, to unpack the Compact, once the wood
crate has been removed, remove the casing (in reverse order as set
out in par.4.2.3). Remove the screw at the base of the heater / boiler
and remove the base from the bottom pallet.
Follow the general guidelines set out in paragraph 1.1 to the letter.
Above all ensure that the flooring of the room where the heater / boiler
will be installed is capable of bearing the weight of the appliance plus
the weight of the water contained in it and the weight of the pellets in
the hopper.
CAUTION: The room in which the appliance will operate must be
adequately ventilated (minimum air intake for an air flow of 1300 m3/h).
The heater / boiler must be positioned at a minimum safe distance
from walls and furnishings. This distance will have to be increased
considerably if the objects surrounding the appliance are
inflammable (matchboarding, furniture, curtains, picture frames,
sofas, etc...). The recommended minimum distances are illustrated
in the drawing below on the right. Installation in the vicinity of heat-
sensitive materials is only permitted if suitable insulating protection is
provided for ( ref. Uni 10683).

The following is a description of the electric wiring for Thermocontrol and H2O 14 / Compact 14: through this electrical
connection, the shut off action by Thermocontrol automatically switches the diverter valve and also switches off the boiler: if the
system Chronothermostat requires more heat the boiler does not switch off until it has satisfied the heating requirements of the
room. The connections to the diverter valve and system chronothermostat are shown in the diagram and in the following photos.
CAUTION: in order to prevent too many boiler start ups, with consequent reduction in the electrical heater lifetime, the
manufacturer highly recommends using a chronothermostat with a thermal hysteresis of at least 2°C.

The heater H2O / boiler Compact can be supplied with a
" Kit for the production of instant domestic hot water" (see par. 4.7) . When
a tap is turned on, the " flow switch" commands the " diverting valve" to
convey the hot water from the boiler to the plate heat exchanger . The
temperature of the domestic hot water obtained in this way is roughly 10° -
15° lower than the temperature in the boiler as indicated on the handheld
radio control and in any case within the limits indicated in par. 2.
Hot water is not available when the boiler is switched off. When
the boiler switched on, upon a request for hot water, it operates at
the maximum steady state level of combustion: the diverting valve
only conveys the water to the plate heat exchanger if the tempera-
ture in the boiler is above 61°.
The manufacturer recommends installing a water softener to ensure an
optimal life of the plate heat exchanger (see par. 4.7). It is also advisable to
regularly clean and check the plate heat exchanger.
The Kit for the production of instant domestic hot water comprises:

CAUTION: The system operating pressure must always be above the expansion tank preload: If the operating pressure of the system is
2 bar, the expansion tank must be preloaded to 1.5 bar.
CAUTION: The Thermocell must also be connected only to 220V - 50Hz power supply"; the adjustments of Sensor 1 and Sensor 2 must
be controlled by the heater / boiler and not by the Thermocell electric panel.
For this purpose connect 2 thermocouples (optional code no. 60010695) to the cable clamps of Sensor 1 and Sensor 2" of
the heater / boiler.
CAUTION: Sensor S1 must be set at 65°C (over 65°C it switches off the boiler ). Sensor S2 must be set at 4045°C (under 40 - 45°C it
switches on the boiler).
CAUTION: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is
not covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing.

pg. XVIII
The safety valve must be connected to the highest part of the heat generator or the outlet tube, next to the generator. The length of the section
of tube between the generator fitting and the safety valve must not be more than one metre. There must be no cocks that can cut off the tube
connecting the safety valve to the heat generator and the section must not be less than the inlet section of the safety valve or the sum of the inlet
sections if there are several valves that head a single tube, at any point whatsoever along its length. The outlet tube of the safety valve must be
installed in such a way that it does not prevent the normal functioning of the valves and will not cause injury to persons ; the outlet must be located
as close as possible to the safety valve and be accessible and visible. The diameter of the outlet tube must not in any case be less than the
diameter of the safety valve outlet fitting. The outlet fitting diameter is the minimum internal diameter of the valve outlet upstream from any existing
internal threading. The valve discharge pressure, equal to the calibration pressure and increased by the overpressure, must not exceed the
maximum working pressure of the heat generator. The designer must ensure that the maximum pressure existing at every point of the system
does not exceed the maximum working pressure of each of its components. The discharge capacity of the safety valve must be calculated
according to the prescriptions set out in UNI 10412/2. The diameter of the minimum net cross section of the valve inlet must in any case be not
less than 15 mm. The maximum working pressure of the closed expansion tank must not be less than the calibration pressure of the
safety valve, plus the specific overpressure of the valve itself, with any difference in height between the tank and the valve taken into
account,and the pressure generated by the functioning of the pump. The capacity of the expansion tank or tanks is evaluated according to the
overall capacity of the plant as per the design. The closed expansion tanks must comply with current regulations governing pressure appliances
in terms of design, construction, conformity assessment and utilization.
The rated volume of the closed expansion tank must be sized in relation to the expansion volume of the water in the
system.
The heat generator must be connected directly to the plant's expansion tank or group of expansion tanks with a tube having an internal
diameter no less than 18 mm. The connecting tube, which may consist of plant parts, must not be fitted with any shutoff cocks or have reduced
sections. One three-way on-off valve may be installed for connecting the tank to the atmosphere for maintenance operations. This device must
be protected against accidental manoeuvres. The connecting tube must be fitted in such a way that no scaling or deposit points are created. If
several heat generators power a single system or secondary circuit, each heat generator must be connected directly to the system's expansion
tank or group of expansion tanks sized overall for the total volume of water contained in the same plant or independent circuit. When it is
necessary to separate the single heat generator from the expansion tank or group of expansion tanks, then a three-way tap having the same
characteristics as those listed above must be installed on the tube that connects the generator to the expansion tank, in order to ensure that the
generator is in any case connected either with the expansion tank or with the atmosphere in every position. The expansion tanks, connecting
tubes, the vent and smoke exhaust pipes must be protected against freezing in areas where this could occur. The solution adopted for this
purpose must be described in the project. Given that the circulation of the water in the heat generator must be maintained in any system and in
all operating conditions within the limits prescribed by the supplier of the generator, in closed expansion tank heating systems, in which the
circulation of the water is assured by means of an electric pump, the pump stopping must not cause, in any operating condition, the temperature
to rise above the limit prescribed in these instructions.
The previous chapter does not replace UNI 10412/2 to which it makes reference . The qualified installer must in any case be
fully aware of this standard and its amending versions.
