Regulation for LPG

Loosen screw A and push support B all the way. Use a double head

wrench to remove nozzle C and assemble the suitable one, following
the instructions indicated in the reference charts, with respect to the
type of gas to use. The screwing torque of the nozzle should never
exceed 3 Nm. Reposition support B so that nozzle C is covered
perfectly.
Move the Venturi tube D to regulate the air flow until distance “X” is
reached indicated in the chart in paragraph “5.4 Regulation of primary
air” and then secure the tube by means of screw A. After the
regulations have been carried out, restore the seals with sealing wax or
equivalent material.
