A question-Does the 10-2-3 rule apply to a heat stack on a gas furnace? Or does this rule only apply to solid fuel fireplaces?

Greg, David supplied the correct answer, nothing more to be added :wink: remember this is technically a vent not a chimney

Yes, typically, I don’t duplicate the answer if I consider it correct.

Hi Guys,

I didn’t think Davids answer was wrong, I was just curious, thought maybe my settings were screwed up:-).
Thanks for the answers, and thank you David for the graph!
