This rigid chimney pipe is designed especially for venting a FMI wood-burning fireplace. The parts feature an insulated steel double wall that allows a 2" clearance to combustibles. Several lengths are available, even up to 48" to reduce the number of connections necessary during the installation. All parts necessary for a complete installation can be found below. These include elbows, firestops, and thimbles as well as the proper terminal at the roof that will protect your chimney from the elements.
