CO2 collected in gas system, vent pipe corroded, the reason could be:

flue cap, rain water is getting down and corroding the vent pipe and then the draft motor and heat exchanger. Or a bald eagle has made a nest in the flue cap, if so leave the nest alone and run a new vent line. Ha you thought I didn,t know the answer
