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 con-
nected 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.

CASCADE+MODBUS mode (fig. 4/d)
This mode allows for MODBUS commu-
nication of at least two boilers in cascade
and is performed by requesting another
RS-485 board provided in the kit code
8092244.
ATTENTION: Communication will occur
only with the MASTER boiler, (boiler
with PAR 15 = 0), interpreting the casca-
de as a single heat capacity generator:
P CASCADE = P BOILER x No. BOILERS.
To install the second board, proceed as
follows:
- Remove the cover and electrical-
ly connect 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 configu-
ration suited to the MODBUS network
(PAR 17 INST) according to Table PAR
17 INST.
RS-485 connection to the INSOL/ZONA
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
indicated in the figure.
CAUTION: For electrically connecting
the INSOL/ZONA MIX board to the boiler
board, refer to the instruction leaflet
provided in the kit.

2.3 CONNECTING UP SYSTEM
To protect the heat system from dama-
ging corrosion, incrustation or depo-
sits, 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 informa-
tion, you may directly contact SENTINEL
PERFORMANCE SOLUTIONS LTD or
FERNOX COOKSON ELECTRONICS.
For long-term protection agains cor-
rosion and deposits, the use of inhibi-
tors such as Sentinel X100 or Fernox
Protector F1 is recommended after cle-
aning the system. It is important to check
the concentration of the inhibitor after
each system modification and during
maintenance following the manufactu-
rer’s instructions (specific tests are avai-
lable at your dealer).
The safety valve drain must be con-
nected to a collection 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 deli-
very/return pipes.
WARNING: Failure to clean the heat
system or add an adequate inhibitor
invalidates the device’s warranty.
Gas connections must be made in
accordance with current standards and
regulations. 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 maximum 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 insi-
de the front panel; it contains all the
technical data identifying the boiler and
the type of gas for which the boiler is
arranged.
2.3.1 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 condensa-
tion 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.
2.3.2 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.
2.4 INITIAL PHASE
SYSTEM FILLING
The charge pressure, at cold start, must
be 1 bar. The filling is to be done slowly
to allow air bubbles to escape through
the air vents.
2.4.1 System draining (fig. 5)
To drain the system, turn off the boiler
and use the discharge valve (1 fig. 5).

2.5 EXHAUST
The boiler is supplied with a 80 mm
gasket, which must be fitted over the
exhaust terminal prior to the flue being
installed
(11 fig. 6 - fig. 7 - fig. 8).
2.5.1 Type B (fig. 6)
If the inlet is not connected, the boiler
should be regarded a Type B device. When
installing the boiler in locations where it
needs to be protected from water, replace
the intake terminal inserted in the flange
with terminal code 8089510.
For information on how to configure the
boiler in this mode see figure
6.
The maximum overall length of ø 80
exhaust flues is determined by the load
losses of the single accessories installed
and should not exceed 16 mmH
2 O .
The exhaust pipe can be connected to
existing chimneys.
When the boiler works at low temperatu-
re 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
protected from direct contact with the
boiler condensation. Combustion pro-
ducts must be conveyed with a flexible
piping or rigid plastic pipes with a
diameter of about 100-150 mm provi-
ding so to the condensation siphoned
drainage at the end of the pipe. The
useful height of the siphon must be at
least 150 mm.
2.5.2 Type C (fig. 7 - fig. 8)
The boiler becomes a Type C device
when the intake terminal is removed
from the flange and the intake is con-
nected to separate exhaust ducts (fig. 7)
or with coaxial exhaust (fig. 8).
2.5.3 Maximum usable length
for separate ø 80 flues
The maximum overall length of ø 80
suction and exhaust flues is determined
by the load losses of the single acces-
sories installed and should not exceed
16 mmH2O.
When the segment of piping is between
11-16 mm H2O it is necessary to check
and, if needed, correct the maximum
and minimum pressure adjustment of
the gas valve as specified in point 4.2.2.
2.5.4 Maximum usable
length for coaxial ø 80/125 flues
In installations with ø 80/125 coaxial
exhaust, the maximum horizontal
length including the 90° curve, should
not exceed 5 m.
For roof exits it should not exceed 8 m
along vertical.
When the segment of pipe is between 2-5
m horizontal / 4-8 m vertical, it is neces-
sary to check and, if needed, correct
the maximum and minimum pressure
adjustment of the gas valve as specified
in point 4.2.2.
WARNING:
Before installing accessories, lubricate the internal part
of gaskets with silicon-based products. Avoid using oils
and greases.
