Boiler Room Venting & Breaching | Superior Boiler

Static pressure of the cool air (1) exerts pressure on the outside of the furnace or boiler, the breeching and stack. The pressure difference between the room air and heated gas (air) causes products of combustion (2) to flow (draft) through the unit and rise through the breeching and chimney.
