5.9 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.
Fit the nozzle with the box spanner, fitting the spanner through
the central hole in the flame stability disk (Fig. 14).
Nozzles with no fuel shutoff needle must be fitted on the nozzle
holder.
To set the delivery range within which the nozzle must work, noz-
zle return line fuel pressure must be adjusted according to
Tab. G and Tab. H (pag. 20).
5.9.1 Recommended nozzles
Intermediate flow rates may be obtained by choosing the nozzle
with a nominal flow rate slightly higher than that actually required.
Complete range of nozzles:

Bergonzo type B5 60°: 150 - 200 - 225 - 250 - 275 - 300 -
325 - 350 - 375 - 400 - 425. We normally recommend 60°

WARNING
It is advisable to replace nozzles every year
during regular maintenance operations.
CAUTION
The use of nozzles other than those specified
by Riello S.p.A. and inadequate regular main-
tenance may result into emission limits non-
conforming to the values set forth by the reg-
ulations in force, and in extremely serious cas-
es, into potential hazards to people and
objects.
The manufacturing company shall not be lia-
ble for any such damage arising from nonob-
servance of the requirements contained in this
manual.
WARNING

Do not use any sealing products such as gas-
kets, sealing compound, or tape.

Be careful to avoid damaging the nozzle seal-
ing seat.

tightly but not to the maximum torque value
provided by the wrench.
