Viessmann Vitodens Horizontal Telescopic Boiler Flue Kit Diameter 60/100mm

This Vitodens flue pack expels gases through the top, rear or side of an internal floor standing boiler and from the rear and side of external ones. Quick to install, the simple push-fit connections form a gas tight seal and remove the need to cut the flue pipe in most cases. No special tools are required for fitting flue extensions. Robust, the anti-corrosive design will last the life of the boiler.
