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..
WARNING: Before installing the boiler,
the installer MUST make sure that the
wall can support the weight.
2.1 INSTALLATION
2.1.1 Single boiler (fig. 4)
–..Boilers. can. be. installed. in. all. domestic.
environments. without. any. whatsoever.
limit.in.terms.of.location.and.comburent.
air.supply.
–..These. boilers. can. also. be. installed. in.
partially.covered.areas,.as.per.EN.15502,.
with. a. maximum. ambient. temperature.
of.60°C.and.a.minimum.ambient.tempe-
rature. of. -5°C.. It. is. generally. advisable.
Single installation
with kit optional code 8101557
WARNING:
- I t is mandatory to arrange the thermal
system with the hydraulic separator.
- W hen replacing one or more boilers in
existing plants, it is advisable to install
a heat exchanger to separate the boiler
circuit from the secondary circuits. See
the pressure curve for the boiler supply
shown in figure 14.

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.

selecting. the. DIP. SWITCH. of. the. board. as.
indicated.in.figure.4/a.
