Inspection this morning. A wood stove located basement is connected to Selkirk stainless steel metalbestos flue pipe. The flue penetrates the block foundation wall BELOW GRADE and runs vertically about 2 feet before emerging from the ground. It then runs vertically at the side of the home with normal above roof termination. Does anyone here know of flue standards that apply to this unusual installation? Moisture, corrosion, leakage, etc are some of the potential issues.
