Suitable for all fuel types Limitations of Use for all Revolving Chimney Cowls
Bungalows & Short Flues - Do not use a revolving cowl on a bungalow or short flue. The cowl will sieze because of the excess temperature, and you will not be covered under guarantee. We recommend the Dragon Cowl
for these types of installation.
Burning Wood - If you intend burning wood when using a revolving cowl, please note that it must be well seasoned or kiln dried. Residues from damp wood will clog any revolving cowl, and you will not be covered under guarantee.
High Winds - High wind areas can be a problem for revolving chimney cowls, and we therefore generally do not recommend their use in coastal areas or areas where there are regular high winds.
Revolving chimney cowls are not a magic solution to all chimney draught problems. Their main function is to cure downdraught. Do not expect them to solve other draught issues with your chimney.
