i want to install a plume management kit to the exhaust flue of my boiler. the outlet is about 18 inches from the soffit on the first floor of the house. my neighbour is not happy that, with the wind in the right direction, the plume blows across her window.
the plume management kit consists of a pipe, about 3 inches and 3 feet long. it will go vertical but will foul with the roof. so i want to drill a hole 3 inches in diameter in the soffit and then another one in the roof tile above so i can pass the pipe through. is this possible?
the roof is tiled, not slate, and i want to make it watertight afterwards. any ideas?
