Preparation for start up

5.6

Nozzle installation

The burner complies with the emission requirements of the
EN 267 standard.

In order to guarantee that emissions do not vary, recommend-
ed and/or alternative nozzles specified by Riello in the In-
struction 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.

Nozzles with no fuel shutoff needle must be fitted on the noz-
zle holder.
To set the delivery range within which the nozzle must work,
nozzle return line fuel pressure must be adjusted according to
Tab. A and Tab. B page 20.

It is advisable to replace nozzles every
year during regular maintenance opera-
tions.

The use of nozzles other than those speci-
fied by Riello S.p.A. and inadequate regular
maintenance may result into emission lim-
its non-conforming to the values set forth
by the regulations in force, and in extreme-
ly serious cases, into potential hazards to
people and objects.

The manufacturing company shall not be
liable for any such damage arising from
nonobservance of the requirements con-
tained in this manual.

WARNING

CAUTION

D3509

Fig. 22

2

Do not use any sealing products such as gas-
kets, sealing compound, or tape.
Be careful to avoid damaging the nozzle seal-
ing seat.
The nozzles must be screwed into place
tightly but not to the maximum torque value
provided by the wrench.
