B-Vent Exhaust Flue Disconnected in Crawl Space

This single wall flue pipe was improperly connected to a B-Vent without the proper transition connector. B-Vents must be connected with approved connections that insert and twist securely together. Wall straps must be used at connections and every 4 feet of vertical installation to secure the pipe. B-Vents must always maintain a 1 inch clearance from pipe and construction materials. You can read additional requirements in the installation instructions below.
