Required with this boiler: a flue kit

The Flue kit selector above Add to cart adds the Greenstar 60/100 standard telescopic horizontal flue kit (350-570mm, 7716191082) by default, as a separate line in your basket. Pick the long kit (570-790mm) for thicker walls, or the 60/100 vertical flue kit for a roof exit.
Only choose "I already have this" if you already have a compatible Worcester Greenstar flue kit for this boiler. Check maximum flue lengths and terminal positions in the installation manual.
