Provide an adequate lifting system.
Be careful as some drops of fuel may leak out
during this phase.
To separate the burner from the cast iron blast tube, proceed as

remove the cover 1)(Fig. 10), the split pin and pin 2), the
nuts 3) and the screws 4).
Pull out the blast tube from the burner by approx. 100÷120
mm and release the driving fork of the head 6) by removing
the split pins 5).
At this point, it is possible to fully pull out the blast tube from
the pins 7).
Fix the blast tube to the boiler by inserting the insulating seal
8) in-between.
After fitting the selected nozzle, fit the burner on the pins 7)
leaving it open by approx. 100 ÷ 120 mm.
Refit the fork 6) fixing it with the split pins 5).
Completely close the burner fastening it with screws 4), fit
the nuts 3), the pin and split pin 2).
