ADJUSTMENT OF THE HOB BURNER
Lacanche's gas appliances are delivered fully adjusted in compliance with relevant regulations and
for use with the particular gas supply (type, pressure) stated in the purchase order and indicated in
the appliance's nameplate.
Nevertheless, after connecting the appliance, the correct operation of the burners (hob and oven)
must be checked. If required, the height of the flame must be adjusted accordingly.
To do this, the gas delivery rate to the burner must be adjusted by screwing in or out the valve
adjustment screw located behind the control knob.
This adjustment is essential when changing the gas supply after having changed injectors (refer to
Section "Change of gas").
WARNING:
The adjustment of burners must be carried out by a qualified technician.

setting.
After about ten seconds to allow for the engagement of the
thermocouple, release the control knob.

slightly the tip of the thermocouple.
►If the flame goes off in the low flame setting, repeat the procedure.
If after several attempts you are unable to hold the flame in the
low flame setting, proceed to adjust the burner (refer to Section
"Adjustment of the hob burners").
►If in the low flame setting, the flame is too strong, then the gas
delivery rate to the burner needs to be reduced.
