Abstract
An exhaust and air intake system for a direct vent fireplace. A low-profile manifold assembly is coupled to a direct vent fireplace and is configured to receive exhaust gases from the fireplace and expel the exhaust gases outside of the building in which the fireplace is located. The manifold assembly also takes in fresh air from outside of the building and provides the fresh air to the fireplace to use during combustion. The manifold assembly includes separate chambers for the exhaust gases and the fresh air so that the exhaust gases and the fresh air do not mix together within the manifold assembly. Several pressure reduction and equalization structures are incorporated into the manifold assembly to regulate the amount and pressure of fresh air provided to the fireplace.
