The insurance company-required "professionals" installed my Tundra furnace last week. What a circus.
As one example, they're on their third attempt at connecting the furnace to the chimney thimble according to the furnace manufacturer's specifications. By this point, they are almost there, except for the parts about "galvanized pipe shall not be used; painted black pipe shall be used" and about "male ends shall point towards the furnace".
I have found some threads about the dangers of galvanized, such as

https://www.hearth.com/talk/threads/toxic-fumes-please-read.28885/
as well as about male ends pointing downward

I previously had a chimney sweep install a SS liner and thimble. We played phone tag, and his voicemail said that galvanized is ok for the chimney connector as long as it is 24 gauge or thicker, and that painted black is galvanized anyways. The furnace installer said his sources also indicated that painted black is galvanized underneath.
The furnace installer also showed me that the thimble is the slightly larger diameter female end, so he has to put a male into it, contrary to the male pointing down.
So does anyone know the story on if there is ungalvanized black pipe?
Does anyone know if thimbles are usually the female end, and the best way to connect to them?
