7.3 Adjustment of the pilot burner nozzle

The nozzle is in the pilot burner itself. Remove the pan grid and the screws that fix the pilot in place.
Carefully pull the pilot towards you, through the opening, until the hex screw is accessible. Remove the
hex screw and unscrew the inner screw. That screw is the nozzle itself, it bears the marking of the nozzle
diameter (OEM is 0,21). Don't lose the spring. Eventually substitute the nozzle and tighten the nozzle
following the table. Put in place the hex screw and tighten it. Insert and fix the pilot burner on the unit
again. Below the table of the pilot burner nozzles:
Natural gas H, E, E+
Natural gas L, LL
Propane (G30/G31)
Propane (G30/G31)
A ¼ of a turn open with natural gas – closed tightly with propane gas.
Should you change the OEM-installed nozzle, please state the substitution with gas type below and also
mark it on the technical data plate.
