    It doesn't cause CO... thats a byproduct of combustion. However it would prevent exhaust flow through the desired path out the chimney and thus would exit through the air intake path into the house.

    Rare to see a "clogged " heat exchanger. Cracked one will for sure let CO into the air flow
