Nozzle installation

–

Fit the nozzle with the box spanner, fitting the spanner through
the central hole in the flame stability disk (Fig. 18).

–

Nozzles with no fuel shutoff needle must be fitted on the nozzle
holder.

–

To set the delivery range within which the nozzle must work,
nozzle return line fuel pressure must be adjusted according to
Tab. G.

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.

The nozzles must be screwed into place tightly
but not to the maximum torque value provided
by the wrench.
