The Brewer Ultimate Flue Outlet is a static anti downdraught chimney cowl suitable for use with gas, oil or solid fuel fired appliances. It is available in both round and square versions.
This model comes with a mesh pre-fitted which is suitable for use with oil or gas fired installations. This cowl can also be used on solid fuel installations by removing the mesh and activating the upstands to provide the increased airflow required.
The Ultimate Flue Outlet (UFO) when originally introduced in 1995, was the first gas chimney cowl in the UK to pass the vigorous requirements of BS7 15:1993 (200mm). Its ever increasing market share is testimony to its extensive benefits, advantages and superior antidowndraught qualities over other cowls.
The UFO MKII cowl incorporates four adjustable upstands that address the need for a greater exhaust area demanded by the use of solid fuels. The compact nature of the UFO MKII means it can be used on several pots on the same stack without modification, something some other cowls cannot achieve.
This square model of the UFO has a base plate size of 338mm x 338mm (13½"x13½") and is designed to fit square pots with internal dimensions between 225mm and 275mm (9"-11").

This chimney cowl uses a strap band fixing method, considered to be the most secure method of fixing chimney cowls in the industry.
Four stainless steel straps attach from the cowl, and a stainless steel band (like a large jubilee clip) secures the cowl to the chimney pot. The bottom ends of the straps are then unturned to complete the installation.
The strap band fixings are included with this cowl.
Just the Job for Square Pots The square UFO cowl, as it's name suggests, is for use with square chimney pots. Very few manufacturers make specific cowls for square pots, prefering to concentrate on the larger market of round pots. So top marks to Brewer Cowls for this one.

This is the ideal cowl for square pots I was familiar with the round version of this cowl, as a gas fitter had fitted one to one of our old square chimneys some years ago. Our other chimney needed a rain cowl and I was very pleased to find that there's now a square version. It was very easy to fit and it does a brilliant job.

So good I bought another one. I was so pleased with my first square cowl, I bought another one to replace the round one fitted when only round was available. Another easy fit - excellent!

Perfect for square pots Easy to fit and does the job
Neat looking and well made It's early days to say how efficient it is! It's easy to fit and inconspicuous when fitted. In our windy spot and with a very tall house, we still get a lot of wind noise carried down the flue pipe but are not aware of any downdraught as yet. Hopefully it will do the trick!
The product did the job Great service, parts arrived as planned. I was pleased with the product so purchased more to do all my chimney pots.
