H Chimney Cowl - St/St Grade 430 - Gas - 100mm

£170.89 (Including VAT at 20%)

Availability: Usually dispatched the next working day.

The H Cowl is probably the ultimate static anti downdraught chimney cowl, as it completely isolates the combustion gases from the prevailing winds.

Manufactured using stainless steel grade 430, and with mesh inserts at the exits, makes this H Cowl suitable for use with appliances fired by oil or gas. Please note that this H Cowl is NOT suitable for use with appliances fired by solid fuel. Please see the solid fuel versions that we have available.

Suitable for use with 100mm internal diameter pipes.

Fitting Instructions
The H cowl has a shaft which is just slightly under the diameter of the cowl, so for example, a 125mm H Cowl will have a shaft with a diameter of around 120mm. It then slides inside the chimney or flue system.

Fitting to a prefabricated chimney system
Slide the cowl inside the chimney system. Secure in place with stainless steel self tapping screws and seal with a high temperature silicone or sealant.

Fitting to a masonry chimney stack or pot
Slide inside the chimney or pot and mortar in place.

Customer Reviews

  Excellent product and service  A really well made cowl easy to fit   (06/05/2016) Bill rampling - Newmarket


  Just what was wanted  Gas engineer refused to certify small businessgas heating system. Saying flue was non compliant. Been all right for the last 20 years!Fitted 'H' pot all now is good.   (07/10/2019) -


  Guaranteed Solution at a Price  The H cowl is going to prevent any downdraught, no question, as the combustion gasses and prevailing wind are completely isolated from each other. The downsides are that it's physically large and, ioho, ugly. There is no fixing method as such, it needs to be cemented in place. Does the job though.   (07/05/2011) fluesystems.com - High Wycombe
