Problems related to residential installations.

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?
