On this job I installed a new inducer motor. Upon taking out the old one I found pieces on trim flue pipe in the inducer wheel that killed the motor. This likely happen when the roofers put the new flue cap on I imagine one of there workers trimmed the flue to fit the cap. They tossed a rolled up piece they trimmed down the pipe on purpose. I also found a flat piece in there that fell in on accident most likely.
