This is a ComfortBilt HP22i Flexible Piping Kit for our pellet stove fireplace inserts.
Only to be installed in a noncombustible enclosure. Not designed for free-standing units, this is only for Inserts.
I purchased the flexible piping to install with my new ComfortBilt fireplace insert. The pipe is very good quality and came with all the fixtures that I needed to complete the installation. Flexible pipe made the chimney install very easy.
Very good price for the package. Does what it is designed to do. No complaints. Good deal.
