The Ultimate Flue Outlet is one of our most popular units for helping to prevent wind-related downdraught. Suitable for round or square pots with an external measurement of 15.5", the unique design redirects wind across the top of the unit rather than blowing down into the flue.

The Multifuel version, as the name suggests, can be used in conjunction with both gas and solid fuel systems (by removing the mesh). Alternatively, the Solid Fuel version comes fitted with larger mesh that doesn't need to be removed for solid fuel.

Manufactured in aluminium and available in either terracotta or black.

The UFO Cowl is made in our own workshops here in England from either aluminium or stainless steel and then powder coated if required.

What is it for?

If you have a problem with downdraught and are burning solid fuel (wood, coal or oil) or using a gas system then the UFO (Ultimate Flue Outlet) Cowl is a good solution and has been used for many years to good effect.  The UFO’s specially shaped discs channel wind to create an updraught (or lower pressure) at the top of the system to counteract wind related downdraught.

Withstands temperatures up to 200⁰C.

What sizes & options are available?

Our UFO Large Cowl will fit onto a round chimney pot with an external diameter of 15.5", or a square chimney pot with an external measurement of 15.5". However, please do not hesitate to contact our sales team, who would be happy to help, if you require a different size or shape.

The UFO Cowl is made in either powder coated aluminium available in terracotta or black

How do I fit one?

For gas systems

The UFO Multifuel Cowl is supplied fully assembled ready for gas installation. Once up on the roof, it is the work of a few minutes to attach the cowl using the stainless steel strap.

For solid fuel systems

Before installing on a solid fuel system the mesh birdguard must be removed, and the four mounting tabs adjusted (full instructions provided) - you may find it easier to order our UFO Solid Fuel cowl which is factory assembled ready for installation on a solid fuel system. Once up on the roof, it is the work of a few minutes to attach the cowl using the stainless steel strap.

** Please note, chimney pots are not included.
