The HART COOLEY hs-csfp is a ceiling support face plate designed to conceal the rough opening left by a ceiling support assembly in all-fuel chimney installations. Available in both 6-inch and 8-inch sizes, this face plate provides a clean, finished appearance where the chimney passes through a ceiling. It is a standard component in through-ceiling B-vent and all-fuel vent system installations and is typically installed by licensed HVAC technicians or chimney professionals during new construction or system retrofits. The part weighs 2 pounds and fits standard ceiling support assemblies in both sizes.
This face plate is used in residential and light commercial all-fuel chimney systems where a ceiling support assembly penetrates a finished ceiling. It covers the cut opening around the support assembly, preventing gaps and presenting a finished look at the ceiling line. Typical installation scenarios include new vent system rough-ins, attic bypass corrections, and chimney liner upgrades where ceiling penetrations are made or exposed.
Designed as an OEM-style replacement or new-installation component for all-fuel ceiling support assemblies in 6-inch and 8-inch chimney systems.
Installation is performed by licensed HVAC technicians or qualified chimney installers following applicable local mechanical codes and NFPA 211 guidelines. Ensure the ceiling support assembly is fully secured and the system is not in operation before fitting the face plate. The face plate should seat flush against the finished ceiling surface for a proper fit. Do not operate the venting system until all components, including the face plate, are properly seated and secured.
