Boiler Flue Extensions

(43 products)

Boiler flue extensions are used to extend a boiler's flue outlet system, effectively an additional flue length of either horizontal or vertical orientation. Flue extensions are brand specific and must be the same brand as the manufacturer of the flue piping system that is being extended. The range covers the most popular brands, lengths and sizes. This must be situated at least 30-60cm from a window or door, preventing harmful gases re-entering the property.
