Knowing there’s only one hole in the church roof to use for a vent, and that I have approximately fifty feet of horizontal vent and approximately one hundred feet of vertical vent, how can I satisfy an inspector, while knowing "no more than one third of a minimum sized vent can be installed horizontally?" I'm thinking over size the vent piping, but by what percent? Appreciate any suggestion. thanks!
