General Safety Information

 

9

After removing the packaging, check the condition and 

completeness of the supply. If there are any problems, con-

tact the company 

R

 that sold the equipment.

 

9

This product must be installed by a legally qualified heat-

ing engineer. On completion of the installation, the install-

er must issue the owner with a declaration of conformity 

confirming that the installation has been completed to the 

highest standards in compliance with the instructions pro-

vided by 

R

 in 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 specified by 

R

R

 declines 

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 sufficient 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 qualified 

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  specified  for  the  boiler.  If  this  is  not  the 

case, contact the Technical Assistance Service 

R

 or pro-

fessionally qualified 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

.

 

9

This manual must be read carefully so as to ensure the cor-

rect and safe installation, operation and maintenance of 

the  appliance.  The  Owner  must  be  adequately  informed 

and trained on how to operate the appliance. Make sure 

that he/she is familiar with all the information required for 

safe system operation.

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 infirm 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

Any technical or cleaning operation is forbidden before:

 

− removing the power supply by setting the main switch of 

the equipment to (I) and the main switch of the system 

to (OFF)

 

− closing the water and fuel shut-off valves

 

0

Do not tamper with or adjust the safety or control devices 

without prior authorisation and instructions from the man-

ufacturer.

 

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 inflammable 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 specific qualification and expertise.

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 vitrified 

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.
