Abstract
A power vented direct vent system for a fuel-burning appliance wherein a power venter is associated with a vent pipe to create adequate draft for combustion. Outside air is supplied to the appliance for combustion and also communicates through a regulator with the vent pipe for addition to the flue gases. The draft regulator assures adequate draft and can be a barometric draft control. The power vented direct vent system is directly connected to the fuel-burning appliance with complete isolation of the combustion system from the space in which the appliance is located.
