Well my fettlingnof my 8 r burner went a bit astray by holding and important part with pliers when heating cherry red to clean it!!! So a couple of helpful folk here recommended Fogas in Sweden. Very quick service and burner fits great BUT I can’t close the case as the clip at the back to locate the burner folks thinks. The new burner is lacking a collar to raise it from the clip. Did i get the wrong one???
