I'm pretty sure they're meant to be glued as well as the little metal bits at each corner poked into the oven 'chassis' - the glue clearly needs to be able to withstand high temps reached during cooking, too.
Anyone offer suggestions of what I should be looking for? Will have a scout round the next DIY place I visit, but is it a specific type of glue for doing this, or some generic glue/something used in some other glueing-in-high-temps application?
Cheers in advance,
PS. Pleased with DIY attempts thus far on new house. Cat flap looks professionally done, so chuffed with that. Ditto with bath re-seal, though have spotted one tiny pinhole in the sealant which needs sorting. Have discovered drilling into plaster/brick is damn sight more difficult than into plasterboard (brick is fine, it's the plaster on top of the brick that's the bit I'm having problems with - it's crumbly and am ending up with holes several sizes bigger in said plaster than the drill bit being used, just cos of the crumbling).
