DuraVent Combustion Air Systems

Improve the efficiency of your central heating system by eliminating the use of conditioned room air for combustion with a DuraVent Combustion Air System. Using system specific triple-wall connector pipe, elbows, and tees to deliver combustion air to the appliance from outside the room through the chimney penetration, DuraVent Combustion Air Systems eliminate the need for a separate penetration in the structure for combustion air. Choose from 6" and 8" DuraVent Combustion Air Systems.
