Hi guys,


I guy just called me. He is getting his home inspected. He said the inspector told him that were his heater system vents in the attic, is at is a single wall and it needs to be a double wall. What is he talking about? ![icon_confused.gif](upload://qv5zppiN69qCk2Y6JzaFYhrff8S.gif)

If you are speaking of the flue, it should be a double wall vent, or a B-Vent.
