I completed my fall clean out including a new combustion blower (complete housing). I got a smoky smell on start up and let it run thinking it was the new blower getting rid of the new smell. I did the flashlight test and spotted smoke on start up. I retightened the blower to the housing to insure the new gasket was seating and resealed all the smoke pipe with 600 degree metal tape. I`m still seeing smoke (not as much as previous, but smoke nonetheless) I cant for the life of me pinpoint where the smoke is leaking from, be it the piping or the blower. Any hints on tracking down this leak? Thanks ,Chuck
