On the Duravent website the warranty for both “DuraPlus” and DuraTech” states, “DuraVent products are fully warranted if installed only by a professional installer.” I would like to do this myself! Then again, maybe not if it voids the warranty. It just gets me thinking and having to ask what exactly do you think their interpretation is of a “professional installer?” Is there some kind of certification that a professional has to have?
