LENNOX 25W91 Transition Flue Pipe

Transition Flue Pipe

The Transition Flue Pipe provides an alternative to the traditional main flue extension pipe used in open-flue gas fire and multifuel stoves. It is fitted at the chimney mouth, with the main flue extension pipe extending from it. The transition pipe provides flexible operation of the stove by allowing either top or rear exit of the stove flue gases, whilst maintaining a direct connection to the stove.
