Hi, Does anyone know where this should be located? I am re-installing my built-in electric oven and hob and I have one of these plates, but I can't work out if it can be flush mounted or if it must be surface mounted. I'm assuming it is supposed to go behind the oven and i'm concerned it wont allow the oven to be pushed in as the back box supplied is very chunky? the plate is PRW217 and the back box is PRW218
