The Traditional 'Super H' Cowl is designed to ensure that no matter what the wind direction or strength the flue or chimney is protected from downdraught. As the wind passes down the top of the external parts, it creates a wind flow that exhausts the smoke and fumes out of the lower exits.

So powerful is this action of the H Cowl that gusts of wind blowing through the air shafts produce an up-draught equal to about 30% of the velocity of the gusts. In normal weather, the 'Super H' Cowl Cowl possessing four outlets to the atmosphere improves any sluggish updraught.
Only the genuine 'Super H' Pot and Cowl has the exclusive design, which converts downdraught into an updraught — no matter how strong or gusty the wind may be.
You simply slip the 'Super H' Cowl cowl into the flue pipe or chimney pot and make the joint airtight. Any space between the sides of the cowl and the inside of the chimney pot or flue must be filled with suitable packing to make sure it is airtight and waterproof.

'Super H' Cowls smaller than 175mm (7") internal diamater must only be used on flue pipes not chimney pots unless the pot is lined.

The 'Super H' Cowl cowl should be positioned so that it faces broadside onto the troublesome wind. It should be as exposed and high as possible.
