Why the H Cowl Cures All Downdraught

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 ?O.H.? Cowl possessing four outlets to the atmosphere improves any sluggish updraught.
Only the genuine ?O.H.? Pot and Cowl has the exclusive design, which converts downdraught into an updraught ? no matter how strong or gusty the wind may be.!!<>!!

Fitting

You simply slip the OH 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.

OH cowls smaller than 175mm (7″) internal diamater must only be used on flue pipes not chimney pots unless the pot is lined.

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

Its sometimes difficult to choose the correct size of Chimney Cowl. We have the perfect solution and can be done from ground level as well. If you can accurately guess the size or width of the chimney pot from the floor you can order the right Cap or Cowl from Chimney Cowl Products. The good news is this is relatively easy once you know the rough size of a house brick and the thickness of the walls of a chimney pot. Using either the naked eye or a set of binoculars get a ‘side on’ view of the chimney pot you wish to cap or fit a chimney cowl, then find a full sized brick nearest to the chosen pot as a reference, normally directly underneath. Now imagine that the brick is placed on top of the chimney pot itself and make a mental note whether it would fit inside, hang over, or sit flush. It may sound silly but once you know that the width of an average UK house brick is 225mm ( 9″ ) for imperial or 215 ( 8 and half ” ) on a modern property, it provides a very accurate impromptu tape measure. The other factor you may need is internal pot size, this can also be guessed quite accurately if you know the average thickness of a chimney pot is about 25mm ( 1″ ) , simply factor this in and you can work out most chimney pot width’s quite accurately. If you have large decorative rolls on top of the pot, make an allowance for this by guessing, using a brick as your guide.
