Colt Top Chimney Cowl – Suitable for All Fuel Types – Due to their rounded shape Colt Tops are found to be more efficient at creating lift whichever direction the wind is blowing, eliminating downdraught. It also channels rain away from the flue protecting your chimney from water entry which can result in messy soot falls and stained walls.

The Colt Top All Purpose (Terracotta or Buff Stone) has a painted finish which is highly resistant to corrosive fuels such as Coalite, Furnacite and anthracite. It is suitable for all fuels.

  • Suitable for Gas Fuels.
  • Suitable for Solid Fuels with mesh removed (the removal of the mesh prevents soot build-up and potential clogging of the mesh holes)
  • Suitable for Oil Fuels

Suitable for 125mm-250mm (5″-10″) internal diameter pots, it is 135mm high and 435mm wide.

The Colt Top All Purpose has been designed and tested (BS715:1993) for use on all types of fires and appliances.

The wind tunnel tested design of The Colt Top uses established, aerodynamic air extraction principles to draw smoke and fumes up the chimney. The shape has been chosen to operate in any prevailing wind direction.

An adaptor plate (available separately ) if you Chimney Pot is Greater than 10″ Internal Diameter

    We are just waiting for the right weather conditions to see if it has fixed our chimney down draught problems.

    With a chimney diameter of 300mm an adapter plate was needed. Although the final install is secure and seems to work the plate is much larger than required.

    Exactly as advertised, easy to fit, waiting for bad weather to see if it functions as advertised

Choosing the Correct Size

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.
