Replacement of gas oven
burner injector
To replace the gas oven burner injector, follow this
procedure:
1. Remove the bottom plate of the oven ("A") to access
the gas oven burner ("B")
2. Undo the two fixing screws ("C") which keep the gas
oven burner in place
3. Gently slide the oven gas burner off the injector
support ("D") and slowly move it to the left hand side.
Check that the burner bush does not slip off the burner
mouthpiece, and take care not to cause stress to the
spark candle connection wire ("E") and the
thermocouple ("F") conductor;
3. With a 7 mm socket spanner unscrew and remove
the gas burner injector ("D"), and replace it with the
required one (see Table on this page);
4. Reassemble the burner following the same procedure
backwards.
The oven burner does not need any primary
air regulation.
