Hi I was wondering if anyone could tell me if there was a Building Code say how far from the ground a exhaust venting pipe has to be. I want to install my pellet stove in the basement, there is concrete from the ground grade to 22" above grade then I have wood shakes for siding. The Pellet stove being installed is a Enviro Maxx. The manual says the vent termination has to be a minimum of 24" above grass plants wood or any combustible materials. Thanks for your help.
