A friend of mine bought a house that has a countryside multifuel stove installed. He has been telling me it burns real dirty so i took my leafblower over and we did a good cleaning. We fired it up and still had a lazy flame. I unhooked the oak and the flame cleaned right up. Whoever installed the oak used 2" pvc but used a reducer to hook up the 2" flex to. After measuring the id was only 1.5". My question is how much air is he loosing?
Thanks
