GENERAL INFORMATION
1 GENERAL INFORMATION
1.1 General Safety Information
9 This product must be installed by a legally qualied heat-
ing engineer. On completion of the installation, the install-
er must issue the owner with a declaration of conformity
conrming that the installation has been completed to the
highest standards in compliance with the instructions pro-
vided by Rin this instruction manual, and that it con-
forms to all applicable laws and standards.
9 This product must only be used for the purpose for which it
is designed and made, as specied by R. Rdeclines
all responsibility, contractual or other, for damage to prop-
erty or injury to persons or animals caused by improper in-
stallation, adjustment, maintenance or use.
9 The room where the boiler is installed must be proper-
ly ventilated to ensure a sufcient supply of air for correct
combustion.
9 In case of water leaks disconnect the equipment from the
power mains, close the water supply and promptly alert
Technical Assistance Service R or professionally qualied
personnel.
9 Regularly check that the condensate drain is free from ob-
struction.
9 The boiler must be serviced at least once a year. The failure
to perform annual maintenance work will void the warranty
of the equipment.
9 Periodically check that pressure in the central heating cir-
cuit, when cold, is approximately 1.5 bar and below the
maximum limit specied for the boiler. If this is not the
case, contact the Technical Assistance Service Ror pro-
fessionally qualied personnel.
9 If the boiler is not going to be used for an extended peri-
od of time, perform the operations described later in this
manual.
9 This manual is an integral part of the equipment and there-
fore must be stored carefully and must ALWAYS accompany
the boiler even if it is sold to another Owner or User or trans-
ferred to another plant. If it is damaged or lost, request an-
other copy from your local Technical Assistance Service R.
1.2 Precautions
The operation of any appliance that uses fuel, electrical power
and water demands that a number of fundamental safety pre-
cautions be respected:
0 Do not allow children or inrm persons to operate the sys-
tem unsupervised.
0 It is forbidden to use electrical devices or equipment, such
as switches, appliances, etc. if there is a smell of gas or un-
burnt products. If so:
−Ventilate the room, opening doors and windows
−Close the fuel shut-off cock
−Ask for the prompt intervention of the Technical Assis-
tance Service
0 Do not touch the boiler while barefoot or wet.
0 Do not plug or block the condensate drain outlet.
0 Never pull, disconnect, or twist the electrical cables coming
from the appliance even if it is disconnected from the mains
electricity supply.
0 Do not obstruct or restrict the vents in the room where the
boiler is installed. Adequate ventilation is essential for cor-
rect combustion.
0 Do not expose the boiler to the elements. It is not designed
for use outdoors.
0 Do not switch off the appliance if the outdoor temperature
may drop to below ZERO (frost hazard).
0 It is prohibited to leave inammable substances and con-
tainers in the room where the boiler is installed.
0 Do not dispose of packaging material into the environment,
or leave it within the reach of children, since it can become
a potential hazard. Dispose of packaging material in com-
pliance with applicable legislation.
0 It is forbidden to operate the boiler without water.
0 The equipment casing must not be removed by people
without specic qualication and expertise.

GENERAL INFORMATION
1.3 Description of the appliance
The light oil condensing thermal unit INSIEME EVO COND B/130
LN is a hot water generator for the heating of environments and
production of domestic hot water (DHW) by means of a vitried
heater. It can function at low temperature and is oil fuelled. The
low NOx burner features a single-stage operation and a vertical
steel combustion chamber. The boiler unit is effectively and ac-
curately insulated with a high-density glass wool mat. The con-
trol panel includes a user interface with display and an elec-
tronic board for the thermal unit adjustment and control, which
allows to manage the control and safety devices in compliance
with the regulations in force.
1.4 Safety and control devices
The control panel, apart from managing the functions of the
thermal unit INSIEME EVO COND B/130 LN, allows highlighting any
anomaly which may affect its correct operation, ensuring the
thermal unit safety by stopping it and automatically closing the
burner light oil valve.
The burner control and adjustment board is also used to ensure
the burner safety by managing its correct operation.
Any anomaly which may affect the generator operation forces
it to stop (lock-out) and is promptly signalled with a numerical
error code on the regulator display.
The following are installed on the water circuit:
−Safety thermostat: tted on the generator body, it in-
tervenes by stopping (permanent error) the thermal unit
if the boiler temperature exceeds the limit threshold of
110°C;
−Safety valve: intervenes if the boiler pressure exceeds the
limit threshold of 3 bar;
−Pressure transducer: sends a signal to the electronic reg-
ulator which views and continually checks the primary
circuit pressure to switch on the generator or cause it to
stop in case of low pressure;
−Boiler temperature probes (delivery and return): im-
mersion probe on the delivery line of the generator is
used by the regulator to view and check the delivery wa-
ter temperature and check the correct switching on and
off of the burner based on the programmed setpoint. The
regulator uses the same probe to switch off the genera-
tor in case of overtemperature, before the triggering of
the safety thermostat. The contact probe placed on the
return line of the boiler is used by the regulator to view
the return water temperature with which it calculates,
together with the delivery temperature, the temperature
difference between delivery and return (∆t), which allows
regulating the modulation of the circulator in heating
mode.
9 The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the manu-
facturer’s Technical Assistance Service immediately.
9 Safety devices must only be replaced by the manufactur-
er's Technical Assistance Service using original spare parts.
Refer to the spare parts catalogue supplied with the boiler.
After making the repair, check that the appliance is working
properly.
0 The appliance must not be put in service, even temporarily,
when tampered safety devices are not in operation or have
been tampered with.
