So the rails for inserting the tray can stay inside my oven. The grate is also pyrolysis-compatible and the instructions for use say that you simply have to remove all accessories that are not pyrolysis-compatible.
I therefore assume that you can also leave a pyrolysis-compatible baking tray in the oven.
I would just like to know if this tray is pyrolysis-compatible or if the coating would be damaged.
I would advise against this. The pyrolysis instructions for the oven state quite clearly that the oven must be empty. For pyrolysis, you even have to remove the rails on which the baking tray is normally placed, otherwise the rails will discolour.
