Valve adjustment
The valve adjusts the control knob. The knob must be set to the
flame saving position ON. Remove the knob and adjust the flame
with the help of a small screwdriver.
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.
