The insulated chimney tee may be used to start chimneys indoors or outdoors using a wall support kit or a masonry pier. A length of insulated chimney pipe is attached to the Tee snout, to pass safely through combustible walls. An insulated tee cap is included and can be removed from the bottom opening for inspection and cleanout. Maximum height of chimney which can be supported by a wall support kit is 50 ft.
