RECOMMENDED NOZZLES
Select the nozzle, with a delivery rating slightly higher than effec-
tively required, from the following types:
FLUIDISCS type W2
BERGONZO type B3 - AA
Angles of 45° - 50° are normally recommended. For narrow com-
bustion chambers, use nozzles with angles of 30° - 35°.
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.

RELATIONSHIP BETWEEN: NOZZLE TYPE AND DELIVERY-RETURN PRESSURE
To set the delivery range within which the nozzle must operate, adjust max. and min. fuel pressure on return from nozzle in relation
to the graphs opposite.
It is advisable to replace nozzles every year
during regular maintenance operations.
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.
