The Brewer UFO Ultimate Flue Outlet when originally introduced in 1995, was the first gas chimney cowl in the UK to pass the vigorous requirements of BS7 15:1993, and its ever increasing market share is testimony to its extensive benefits, advantages and superior antidowndraft qualities over other chimney cowls.

The new U.F.O MKII version incorporates four adjustable upstands that address the need for a greater exhaust area demanded by the use of solid fuels, whilst the compact nature of the U.F.O MKII means it can be used on several pots on the same stack without modification, something some other cowls cannot achieve.


When the UFO MKII is used on a solid fuel system, the gas birdguard must be removed.
