My "Ideal Mexico 24kW" boiler is in an upstairs cupboard and has no dedicated air vent, just a louvered door to the rest of the house. I have been told that it should have a dedicated air vent to the cupboard, I can do this by putting a hole into the ceiling and adding a conduit to a vent on the roof.
Does anyone know what the cross sectional area needs to be to meet current regulations?
