Hi, Our boiler is in the kitchen and its vent/flue sits in the external kitchen wall at the front of the house. We want to build a lean-to-style timber-framed pergola with a Twinwall plastic roof along that wall creating light unenclosed outside the kitchen windows, the Pergola extends 3m from the kitchen wall. The vent/flue will be under it - from where the rafter board connects to the wall of the lean. The pergola will be open along the front, and one end (the other end will butt up against a fenced wall) we want an area outside to put a bench to sit on the deck built under it. to prevent gases from building under the Pergola we added a Plume kit at 87 degrees that go through a cutout in the plastic roof and extends at least 600mm above. Is this design safe?
