question about code and flue pipe?
I have a couple questions. Is there a minimum height requirement for the flue pipe before using an elbow at the top of the furnace for a 80% furnace? Does code dictate using a bottom return box as opposed to using side return? thankslearn from yesterday, experience it today, gain knowledge for tomorrow.

code does not dictate how your ductwork is. unless you have a open return in the same room as the appliances.
depends on manufacturer with the venting. You should be able too. I would let my combustion analyzer tell me if i could or not.

Bottom return vs side return will usually depend on how much air the furnace has to move. What BTU rating is the furnace?
