When opening the burner, it is advisable to support its weight by suitable means or using the wheeled support unit available on request.
ADJUSTING THE NOZZLE PIN OPENING ROD
When installing for the first time and after performing any maintenance work or changing the nozzle, reset lever 15) as specified below:
with the nozzle fitted, loosen the nut with extension 17);
screw in extension 17) by hand until you have eliminated all play on lever 15);
