Checking the flame setting
Heat the burner with the knob in maximum position for 10 minutes.
Then turn the knob to the saving position. The flame should not be
extinguished or moved over the nozzle. If either of these two
situations occurs, you will need to reset the valve.
Note: it is the user's choice whether to convert the unit to another gas
type. A person trained and authorized by the supplier must make this
adjustment.
FLAME SELECTION
If the burners are set correctly, the flames should be light blue, and
the inner cone should be clearly visible. The size of the flame depends
on the position of the control knob of the selected burner.
