IMPORTANT
When carrying out commissioning of the boiler, you are highly recommended to perform the following checks:
–
Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.
– Make sure that the electrical connections have been made correctly and that the earth wire is connected to a
good earthing system.
– Open the gas tap and check the soundness of the connections, including that of the burner.
– Make sure that the boiler is set for operation for the type of gas supplied.
– Check that the flue pipe for the outlet of the products of the combustion is unobstructed and has been properly
installed.
– Make sure that any shutoff valves are open.
– Make sure that the system is charged with water and is thoroughly vented.
– Check that the circulating pump is not locked.
– Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the gas
valve inlet.
–
The installer must provide the user with instruction in operation of the boiler and safety devices and hand over the
instruction booklet to the user.

The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions
contained in this manual.
Furthermore, the installation must be in
accordance with current standards and
regulations.
2.1 INSTALLATION
2.1.1 Single boiler
– Boilers can be installed in all domestic envi-
ronments without any whatsoever limit in
terms of location and comburent air supply.
–
These boilers can also be installed in par-
tially covered areas, as per EN 297, with a
maximum ambient temperature of 60°C
and a minimum ambient temperature of -
5°C. It is generally advisable to install the
boilers below weathered roofs, on the bal-
cony or in a protected niche, to protect
them from exposure to weathering agents
(rain, hail and snow). All boilers provide a
standard antifreeze function.
2.1.2 Sequence/cascade boilers
(fig. 4/a)
In the event of sequence/cascade installa-
tion, you must modify for every single boiler
of the main unit the following installing
parameters:
- PAR 1 = 4
(for G20 NATURAL GAS boilers)
- PAR 1 = 12
(for G31 PROPANE boilers)
Refer to section 3.3 to access the INSTAL-
LER PARAMETERS section.
ATTENTION: In sequence/cascade instal-
lations, it is mandatory to arrange the
thermal system with the hydraulic sepa-
rator and safety devices.
The boiler is provided with the board RS-
485 that permits to manage up to 8 boilers
in cascade and communication in MODBUS.
The board is placed on the back of the con-
trol panel.
Access the board and chose the desired
operating mode (CASCADE or MODBUS) by
selecting the DIP SWITCH of the board as
indicated in figure 4/a.
CASCADE mode (fig. 4/b)
Electrically connect all the boilers that form
the modular cascade thermal system and
set installer parameters PAR 15 on every
single boiler as indicated in fig. 4/b.

ATTENTION: Communication will occur
only with the MASTER boiler, (boiler with
PAR 15 = 0), interpreting the cascade as
a single heat capacity generator:
P CASCADE = P BOILER x No. BOILERS.
To install the second board, proceed as fol-
lows:
- Remove the cover and electrically con-
nect the second RS-485 board equipped
with lid to the RS-485 board already
installed in the MASTER boiler (boiler with
PAR 15 = 0) with the wired connector
provided in the kit.
CAUTION: Insert the wired connector
with caution.
- Set the DIP SWITCH of the new board in
MODBUS mode.
- Close the lid of the second board.
- Choose the communication configuration
suited to the MODBUS network (PAR 17
INST) according to Table PAR 17 INST.

MIX (fig. 4/e)
The RS-485 board can be connected to
optional INSOL kit code 8092254 or ZONA
MIX code 8092252. Both require the
board housing kite code 8092236.
Carry out the electrical connections as indi-
cated in the figure.
CAUTION: For electrically connecting the
INSOL/ZONA MIX board to the boiler

below 6°C. The anti-freeze function is ensu-
red, however, only if:
- the boiler is correctly connected to the
gas and electricity supply circuits;
- the boiler is constantly fed;
- the boiler ignition is not blocked;
- the essential components of the boiler
are all in working order.
In these conditions the boiler is protected
against frost down to an environmental
temperature of -5°C.
ATTENTION: In the case of installation in a
place where the temperature drops below
0°C, the connection pipes must be pro-
tected.
2.2 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, before
installation it is extremely important to
clean the system using suitable products
such as, for example, Sentinel X300 (new
system), X400 and X800 (old system) or
Fernox Cleaner F3. Complete instructions
are provided with the products but, for
further information, you may directly con-
tact SENTINEL PERFORMANCE SOLU-
TIONS LTD or FERNOX COOKSON ELECTRO-
NICS.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 or Fernox Protector F1 is
recommended after cleaning the system. It
is important to check the concentration of
the inhibitor after each system modifica-
tion and during maintenance following the
manufacturer’s instructions (specific tests
are available at your dealer). The safety
valve drain must be connected to a collec-
tion funnel to collect any discharge during
interventions. If the heating system is on a
higher floor than the boiler, install the
on/off taps supplied in kit optional on the
heating system delivery/return pipes.
WARNING: Failure to clean the heat
system or add an adequate inhibitor inva-
lidates the device’s warranty.
Gas connections must be made in accor-
dance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity
volume (consumption) in m3/h and gas
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than:
– 1.0 mbar for family II gases (natural gas);
– 2.0 mbar for family III gases (butane or
propane).
An adhesive data plate is sticked inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
2.2.1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building’s sewer pipes.
2.2.2 Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate
to entrap all the impurities in the gas or in
gas main pipes.
To prevent malfunctioning of the valve, or in
certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
2.3 INITIAL PHASE SYSTEM FILLING
(fig. 5)
The charge pressure, with the system cold,
must be between 1 and 1.5 bar.
The filling is to be done slowly to allow air
bubbles to escape through the air vents.
2.3.1 System draining (fig. 5)
To drain the system, turn off the boiler and
use the discharge valve (5 fig. 5).
2.4 FORCED EXHAUST
TYPE B23P-B53P (fig. 6)
This type of exhaust is made with the sup-
plied adapter or 60/80 provided as optio-
nal (code 8089923) for installation type
B23P-B53P. To set this exhaust configura-
tion, refer to fig. 6. The boiler is provided
also of a rubber gasket Ø 80 to be used as
shown in the figure.
The maximum total length of the exhaust
pipe ø 80 is determined by the load los-

ses of the individual accessories inserted
and must not be more than 15 mm H2O.
(ATTENTION: the total length of each pipe
should not exceed 50 m, even if the total
loss is below the maximum applicable
loss.)
The exhaust pipe can be connected to exi-
sting chimneys.
When the boiler works at low temperature
is possible to use normal chimneys at the
following conditions:
– The chimney must not be used by other
boilers.
– The inside of the chimney must be pro-
tected from direct contact with the boi-
ler condensation. Combustion products
must be conveyed with a flexible piping
or rigid plastic pipes with a diameter of
about 100-150 mm providing so to the
condensation siphoned drainage at the
end of the pipe. The useful height of the
siphon must be at least 150 mm.
For the accessories load loss refer to
Table 1.
2.5 INSTALLATION OF SEPARATE
DUCTS TYPE C (ø 80)
This type of exhaust is made with ø 80 poly-
propylene accessories and without the use
of gasket or sealant in type C installation.
The maximum overall length, resulting
from the sum of all the suction and
discharge pipes, is determined by the
load losses of the single connected acces-
sories and should not exceed 15 mm H2O
(ATTENTION: the total length of each pipe
should not exceed 50 m, even if the total
loss is below the maximum applicable
loss.)
See Table 2 for information on the load los-
ses of single accessories and the example
of fig. 6/a for information on how to calcu-
late load losses.
2.5.1 Separate ducts kit (fig. 6/b)
The diagrams of figure 6/b show a few
examples of the permitted exhausts confi-
gurations.
2.5.2 Connection to existing flues
The ø 80 exhaust pipe can also be connec-
ted to existing flues.
When the boiler runs at low temperature,
it is possible to use standard flues provided
that:
- The flue is not be used by other boilers.
- The interior of the flue is protected to
prevent a direct contact with condensa-
tion
from the boiler. The products of
combustion must be conveyed through a
flexible or rigid plastic pipe around 100
to 150 mm in diameter, and condensa-
tion must be siphoned off at the foot of
the pipe. The usable height of the water
trap must be at least 150 mm.
