Nozzle installation
The burner complies with the emission requirements of the EN
267 standard. In order to guarantee that emissions do not vary,
recommended and/or alternative nozzles specified by Riello in
the Instruction and warning booklet should be used.
It is advisable to replace the nozzle once a year
during periodical maintenance.
ATTENTION
The use of nozzles other than those specified by
Riello S.p.A. and inadequate regular maintenance
may result into emission limits non-conforming to
the values set forth by the regulations in force, and
in extremely serious cases, into potential hazards
to people and objects.
CAUTION
The manufacturing Company shall not be liable
for
any
such
observance of the requirements contained in this
