Replacing the main burner nozzles of the
normal burner and large burner
• Detach the safety spring on the supply lines.
Leave the electrode connected. Unscrew the
burners from the trough (Torx T20) and pull off the
burner from both supply lines.
• Carefully pull off both main nozzles together with
the O-ring by hand.
• Check whether the O-rings of the new nozzle
seats are fitted correctly. Fully push nozzles onto
the supply lines.
Note:
do not bend supply lines.
• Push the burners onto the supply lines.
Push the safety springs back on.
• Screw the burners back on the trough.
• Loosen the locking screw and adjust the air
regulation bush according to the nozzle table.
Tighten the locking screw.
• Fit the trough and tighten it firmly.
Checking functions
The flames are adjusted correctly if no yellow tips
are visible and if they do not go out when switching
over swiftly from the high to the low setting.
Please do not forget to stick the new adhesive label
included with the nozzle set over the old adhesive
label on the gas connection, thus documenting the
changeover to a different gas type.
