The Bosch 63002401 heat insulation set is designed to line the burner door on non-condensing oil-fired boilers, shielding the metal door from the radiant heat of the combustion chamber while holding firing temperatures inside the boiler rather than letting them escape through the front. It comes as a layered assembly rather than a single pad: a thick refractory board shaped to match the door profile with a pre-formed central port that aligns with the burner tube, a smaller octagonal refractory ring that seats over that opening, and a soft white ceramic fiber gasket that compresses around the burner to seal the joint where it enters the chamber. Metal retaining clips are already fitted to the back of the main board, and the mounting screws and washers are supplied, so the insulation locates and secures to the door without additional fabrication or trimming.
