• Set the gas valve to the "minimum
rate" position of the inner crown only.
• Remove the knob.
• Using a screwdriver turn the screw
"F3" until the correct setting is obtained
(fig. 9.13).
Outside crowns of DUAL burner:

• Set the gas valve to the "minimum rate"
position of the inner + outer crowns.
