Distance between outside vent pipes - gas furnace

Post by jsp267267 » Tue May 07, 2013 9:13 pm

Could someone please tell me what the minimum (and max) distance should be between the 2 pipes venting outside for a 2 pipe gas furnace?

It varies depending on your local building code and the equipment manufacturer's installation guide. The building inspector is a good person to ask since he'll have to inspect your work later.

It looks like the manual says 12" minimum and doesn't give a max. Mine are only 3". This was installed a couple of years ago and I found out a permit wasn't pulled. Thoughts?
