Nozzle installation
The burner complies with the emission requirements of the UL 296
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 dur-
ing periodical maintenance.
WARNING
The use of nozzles other than those specified by Ri-
ello 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.

The manufacturing company shall not be liable for
any such damage arising from non-observance of
the requirements contained in this manual.
In order to assemble the nozzle, proceed as follows:

install the nozzle 1)(Fig. 14);
fitting the wrench through the central hole in the flame stability

kets, sealing compound, or tape.
