Instructions for the Installer
When the hob has been fully installed it will be necessary to check the minimum flame setting. To do this, follow the procedure below. 1) Turn the gas tap to the MAX position and ignite. 2) Set the gas tap to the MIN flame position then turn the control knob from MIN to MAX several times. If the flame is unstable or is extinguished follow the procedure below. Procedure: 1) Re-ignite the burner and set to MIN. 2) Remove the control knob. 3) To adjust, use a thin bladed screwdriver and turn the adjustment screw (it can be located down the centre of the gas tap shaft or on the tap body, according to the different models - see diagram) until the flame is steady and does not extinguish, when the knob is turned from MIN to MAX. Repeat this procedure for all burners.
Minimum adjustment screw
1) Remove left hand pan support and front left burner cap and crown. 2) Fit manometer tube over the injector. 3) Turn on the burner gas supply and ignite another burner supply. The pressure reading should be nominally 20mbar and must be between 17 mbar and 25mbar. 4) Turn off the burner supplies.
