Need help. How much clearance between pergola and gas fireplace exhaust?
On my main floor I have a gas fire place exhaust that points out to my backyard about 9' high from my future deck. I am wanting to build a pergola off the back of my house but the exhaust vent interferes with the post being up against the house. How far away does the post need to be from the fireplace exhaust?
