SETTING THE BURNER MINIMUM (Valves may vary)
When switching from one type of gas to another, the minimum flow rate must also be
correct: the flame should not go out even when passing suddenly from maximum to
minimum flame.
To regulate the flame follow the instructions below:
– Light the burner
– Set the gas valve to
LO position
– Remove the knob
– With a thin screwdriver, turn the regulation screw (Figs. 2.9a and 2.9b) until
adjustment is correct. On some valves, you need to pass by the hole of the
microswitch (Fig. 2.9a) to turn the regulation screw.
For LP/PROPANE gas, tighten the regulation screws completely.
