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.
WARNING
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 damage arising from non-observance of
the requirements contained in this manual.
Fit the nozzle with the 24-mm pipe wrench, passing through the
central opening of the flame balance disc (Fig. 15) or remove the
lance.
Do not use any sealing products such as gas-
kets, sealing compound, or tape.
Be careful to avoid damaging the nozzle seal-
ing seat.
WARNING
The nozzle must be screwed into place tightly
but not to the maximum torque value pro-
vided by the wrench.
