2Installation
2.1 External air intake and fume exhaust
For proper operation, the thermo-stove must be positioned in a place where the air necessary for
combustion can flow. Air inflow must take place directly through permanent openings (according to UNI
10683) applied on outside-facing walls having the following features:
Be made in such a way that they can not be obstructed, either from the inside or the outside;
Be protected with grid, wire mesh or suitable guard, provided that it does not reduce the minimum
cross-section of 100 cm.
The minimum volume of the room must not be less than 30 mᶾ.
Air flow can also come from rooms adjacent the installation room, provided that the former are equipped
with an external air intake and NOT used as bedroom and bathroom or, do not present fire hazards, as
storage areas, garages and warehouses for combustible materials may be. Fitting operations must strictly
comply with the provisions of current regulations.
The combustion air inlet of the stove must be made with a Ø50 pipe provided by the customer and fitted in
the rear part.
Installation in bedroom, bathrooms or shower is not permitted, as well as any area in which another
heating appliance without independent inflow (fireplaces, stove, etc.) is already installed
2.2 Flue and smoke pipe
The discharge of combustion by-products must be through the rooftop and take place in 3 different ways:
Using an external flue duct, which must have a minimum internal diameter of 80mm and using
only insulated pipes (double-walled) in stainless steel fixed to the wall (Fig. 8).
By means of a flue, which must have internal dimensions not exceeding 200x200mm; otherwise,
or in case of bad conditions (e.g., cracks, poor insulation, etc), we recommend inserting inside the
barrel a stainless steel pipe of adequate diameter that develops along its entire length up to the
chimney pot (Fig. 9).
By means of a flue or smoke pipe connection which, for proper functioning, immediately
downstream the stove must feature a vertical section of at least 1500mm of height and minimum
horizontal sections having a total width not exceeding 4000mm with an upward slope of no less
than 3% (Fig.10). Moreover, for each 90° bend, we recommend extending the vertical section by 1
m and for each horizontal section, extending the vertical by 2 m. In the case of vertical
developments greater than 7 meters, it is necessary to use pipes with a 100mm internal diameter.

These connections, provided for by the UNI 10683 standard, guarantee the discharge of
combustion fumes even in the event of a temporary lack of electrical current. (Fig. 10).
Then ensure that:
There is a minimum draft of at least 10 Pa.
Flue gas exhaust system must always end with a windproof chimney.
Both in the case of an external or internal chimney flue, it is necessary to perform for
periodic checks, while cleaning must be performed annually.
In the event that the smoke outlet pipes pass through flammable material, cover it with
an insulating material (Class A1) of suitable thickness.

* The following output is installed only in models with domestic hot water production.
IMPORTANT: Provide the water connection to a heating system capable of dissipating the maximum
rated thermal power of the appliance.
After checking inputs and outputs of water system, in relation to the type of installation to be made,
outfit the system taking into consideration some important issues:
For connection of product to couplings, preferably use flexible hoses to facilitate moving the
heater in case extraordinary maintenance must be performed at a later time.
Complete the connections by interposing shut-off cocks (ball valve cocks), in order to simplify
any extraordinary maintenance.
Connect the outlet of the safety valve to a disposable discharge.
If the model with domestic hot water production is to be installed, consider installing a 6-bar
safety valve.
In order to reduce limestone build-up, which cause pipes to clog, we recommend installing a
water softener if water is particularly hard (above 20°F).
2.3.1 Domestic hot water function
The production of domestic hot water is automatically managed by the components in the water kit
illustrated above.
The kit is fitted with a flow switch that detects the water flow for domestic use, which, in turn, allows the
3-way motorized valve to exchange with the plate heat exchanger contained in the kit.
At this moment, therefore, the water from the heating unit is pushed by the circulation pump through the
plate heat exchanger, thus producing hot water for domestic use.
To allow production of domestic hot water, the temperature in the heating unit must be at least 55° (Th20);
after determining flow and temperature suitability of the machine, the control unit sets the temperature

9
2
within the heating unit to 70° (Th21 - Ih21) and combustion is regulated on the basis of this value. When
there is no longer any request, the Sanitary Function ends at timer expiration (T68) set to 20sec by default,
repositioning the heating unit thermostat to the original temperature.
It is also advisable to use the sanitary function with heating unit temperatures not below 65°, in order to
optimize production of hot water and avoid the risk of cold outflow.

The operating logics for the various types of system configuration will be illustrated below.
Configuration 0 - P26 = 0 - Factory default
System combined with gas boiler in the heating version only.
To connect the thermo-stove to another (gas-operated) boiler to a closed-vessel water system, it is
advisable to install a Plate Heat Exchanger, keeping the water circuits of the two heat generators separate.

10
2
The operation of the Garda thermo-stove is a priority compared to the work of the combined boiler, since
the most economical fuel is pellet-operated.
The control unit is able to automatically manage the work between the two machines by connecting a 3-
way motorized valve.
In this case, the Boiler Probe (S1) detects the temperature of the machine body of the thermo-stove; once
the probe reaches the temperature of 50° (Th19), circulator P1 of the thermo-stove starts to exchange with
the system and the motorized valve P2 with thermostat set at 50° (Th56) opens the circuit between system
and thermo-stove.
Vice versa, when the temperature read by the S1 probe is lower than 50° (Th56), the 3-way motorized valve
(P2) exchanges, allowing the gas boiler to heat the domestic system.
Independent-operated system with DHW production.
System heating logic:
The thermo-stove is powered by pellets, the only heat generator for the heating and sanitary system (or, at
minimum, management between the thermo-stove and the gas boiler is carried out manually by the end
user).
Therefore, probe S1 detects the temperature in the boiler body and regulates the start of the circulator P1
once the machine reaches 50° (Th19).
DHW production logic:
The thermo-stove features a flow switch (FL) that detects the request of the hot water for domestic use;
with the operation of the flow switch, the electronic control unit automatically diverts the flow to the plate
exchanger through the motorized valve (P2) for the instantaneous production of domestic hot water.
Furthermore, as the thermo-stove detects the DHW request, it reaches its temperature of 70° (Th21-Ih21)
to guarantee constant production of hot water.
In this case, if the installed thermo-stove also produces domestic hot water, flow switch, plate exchanger
and motorized valve are already present inside the product.
Configuration 2 - P26 = 2 - Sanitary Boiler
To prepare the thermo-stove for heating a storage cylinder for sanitary use, also requires performing the
following operations:
Enter the System Menu - Default Settings, and set Technical Parameter P26 to 2.
Set the temperature you wish for water inside the Boiler (Factory settings 65°), in the Puffer
Thermostat, in the User Menu - Heating Management - Puffer Thermostat.
Connect an optional probe (NTC 10K @ 25°C) to terminals 34 and 35 of the electronic control
unit terminal board and firmly insert it into a boiler to allow the thermo-stove control unit to
detect the temperature inside the boiler.

11
2
Connect the terminals of the 3-way motorized valve P2 to the Aux1 output of the electronic
control unit
System heating logic:
By setting parameter P26 = 2, you choose the configuration shown in the figure above.
The circulator is active if the water temperature in the boiler (S1) exceeds the value of the Th19 thermostat.
To avoid water freezing, the circulator is activated if water temperature in the boiler drops below 5° (Th18).
If the water temperature in the boiler (S1) exceeds the 80° threshold (Th21), the P1 circulator is always
active for safety reasons.
DHW production logic:
The valve (P2) diverts the thermo-stove inlet towards the Sanitary Boiler if the water temperature in the
boiler does not exceed 75° (Th58) and the boiler water temperature (S1) exceeds 55° (Th20) .
For safety reasons, if the boiler water temperature (S1) exceeds the value of the Th21 thermostat, the valve
switches to the heating system.
Note: By setting the Summer mode (Domestic hot water production only), when the water temperature
inside the boiler reaches 65°C (Thermostat Puffer), the heater is in Standby mode.
When water temperature inside the Boiler falls below 63°C (Puffer temperature - Ih58), the thermo-stove
comes out of the Standby, thus igniting.
Configuration 4 - P26 = 4 - Accumulation Puffer
To prepare the thermo-stove for heating an accumulation puffer, it is also necessary to perform the following
operations:
Enter the System Menu - Default Settings, and set Technical Parameter P26 to 4.
Set the temperature you wish for water inside the Puffer (Factory settings 65°), in the Puffer Thermostat,
in the User Menu - Heating Management.
Connect an optional probe (NTC 10K @ 25°C) to terminals 34 and 35 of the electronic control
unit terminal board and firmly insert it into a boiler to allow the thermo-stove control unit to
detect the temperature inside the boiler.
Connect the second P2 circulation pump to the Aux 1 output of the electronic control unit,
specifically to terminals 22 and 24.

12
2
System heating logic:
If the temperature in boiler S1 is greater than the Pump activation thermostat equal to 50° (Th19), the
system heats the water of the Puffer if the difference between S1 and S2 is greater than 5°C (Th57).
If the water temperature in the boiler (S1) exceeds the 80° threshold (Th21), the P1 circulator is always
active for safety reasons.
Circulator P2 is activated when the puffer exceeds 60° (Th59).
2.3.3 System filling
Do not operate the thermo-stove for any reason if the system is not filled with water, as the product may be
damaged irreparably.
To fill the system, proceed as follows:
If the installed version also features production of domestic hot water, load the system from the black
knob located under the product water kit; otherwise, if the model is only for heating, load the system
from the return through the filling unit placed on the system itself.
Open all the radiator vents so as to avoid air pockets in the system, which would then hinder the normal
water circulation.
Purge the air through the vent valves installed in the system and in the radiators.
Check that the vent in the machine body is loose, then remove the top cover using the special lever (used
to open the loading door) and slightly unscrew the cap placed on the automatic vent valve in the delivery
pipe towards the right side of the product.
Using the electronic control unit and check the heating circuit pressure. From the main display screen,
double-click the arrow at the bottom right (↓) and check that the pressure read is about 1000 mbar with
the system at room temperature.
Perform an air release from the radiator valves.
Check that the system pressure is stable, checking for any water leaks.
If the pressure is stable and no water leaks, the product is hydraulically ready.
3Electronic central unit
In addition to performing all management and boiler operation control functions, the electronic control unit of the
thermo-stove is also equipped as standard with the following features:
Antifreeze function (automatic activation of the circulator with water temperature lower than or equal to
5°);
Circulator or solenoid valve anti-lock function (automatic activation of the circulator and of the solenoid
valve for 20 seconds every 7 days of inactivity);
Automatic management of domestic hot water production only in models that provide it;
Management of a possible storage Boiler for Healthcare use;
Management of a possible storage Puffer for heating and sanitary purposes;
Automatic work management with a combined (Gas-operated) boiler.
Input for connecting an additional room thermostat.
Serial port (RS232) for connecting a GSM modem (Wi-Fi) and for updating the control unit.

3.2 Ambient probe - Ambient thermostat
To configure the work of the thermo-stove with an ambient probe or room thermostat, parameter A19 must be
changed, if in clamps 27 and 28 of the printed circuit board is connected to:
Ambient probe (as installed by the factory) set A19 = 1 (already set in Default).
The supplied NTC 10K probe, the reading range is 0 ÷ 50°C with the accuracy of 1°C. If the probe is
disconnected, a temperature value of 0°C will be read; in the case of short circuit, the temperature
detected will be maximum (50°C).
Or, if you wanted to connect a:
Ambient thermostat set A19 = 0
By setting parameter A01 in the System Menu, the ambient probe or thermostat can be operated according to
the user's needs.
If A01 = 0
Ambient probe/thermostat not reached: the System goes into Check-up status.
Ambient probe/thermostat reached: the System goes into Shut-off status.
If A01 = 1 (default setting)
Ambient probe/thermostat not reached: the System goes into Normal status.
Ambient probe/thermostat reached: the System goes into Modulation status.
If A01 = 2
Ambient probe/thermostat not reached: the System goes into Normal status.
Ambient probe/thermostat reached: the System goes into Standby status.
If A01 = 3
Ambient probe/thermostat not reached: The system reactivates Pump 1.
Ambient probe/thermostat reached: if the boiler water temperature exceeds the value of the Th19
thermostat (50°C), the system blocks Pump 1 until reaching the Th21 thermostat (80°C).
If A01 = 4
Ambient probe/thermostat not reached: the System reactivates the system pump and goes into Normal
mode.
Ambient probe/thermostat reached: the System goes into Standby mode and blocks Pump 1, as in case
3.
If A01 = 5
Ambient probe/thermostat not reached: Heating vent operates properly.
Ambient probe/thermostat reached: if A11 = 0, the heating vent is switched off, if A11 = 1 goes to Power

Output configurability legend:
Output disabled: In this case, the output is disabled so it does not send any signal.
Output for Safety Valve/Auger2: If used as Safety Valve, the Auger will only activate
when timer T40 expires; If used as Auger2, it will deactivate only at the expiration of
timer T27.
Output under Thermostat: The output is managed by thermostat Th56; above this value,
the output is powered.
Output for Warm Air Fan: The output manages the work of a fan for the production of
hot air in the environment
Output for Summer/Winter Valve: If P51=12 a voltage is guaranteed between pins 22-24
in Summer mode, and between pins 22-23 in Winter mode.
Output for Pump 2 or solenoid valve: The output manages the Solenoid valve or Pump2
of the selected Hydraulic system.
Output under Thermostat 2: The output is managed by thermostat Th60; above this
value, the output is powered.
