I have an upstairs flat, with a conventional flued boiler of about 14KW IIRC. Flue is taken into roofspace and then out through the roof.The boiler is in a cupboard on the landing, vented at high and lowlevel.Outside air was supplied through a vent at low level in an outside door directly off this landing, on the same side of the building as the flue.I have had the flat double-glazed so this vent no longer exists.(premises unoccupied and supply currently capped at meter atm)DG people have suggested a highlevel (over opening door) vent.Without giving specific advice, can anybody tell me if this would ever be acceptable please, or share outcome of any similar experience? Many thanks for any help you can give
