ok guys plumber came and installed the 4" flue pipe....
The exhaust smell is gone but it has been replaced with a new smell..... it smells like metal smell....the plumber wrapped all the connections with foil tape where he put the 3 screws in each connection.
Could this be the adhesive glue cooking off and causing this odor? the piping is 4" 26 gauge if that matters....
I don't know if new pipes should be giving off any odors
Thats why I ask the experts here. If it is the adhesive on the tape cooking up does it only last for a few cycles?
Thank you so much, everyone here has been great
