new.24 month warranty size from 150mm to 300mm The Rotovent Dragon is a device, which, in a dynamic way, uses the force of the wind to increase chimney draught, and prevent downdraught. The cap always places itself in the opposite direction to the wind no matter of its strength or direction. It can be mounted on gravitation based chimney ducts, ventilation, flue and smoke. The special patented rotating system has ball bearings, which are uniquely placed outside of the cap, enabling the Dragon to withstand temperatures up to a massive 500C. This high working temperature enables the Dragon to be used on wood coal burning and multi fuel stoves, even on shortbungalow chimneys.dyfrent size available from 150 to 300mm CE Approved tel https://www.youtube.com/watch?v=LlVOQwNrhNA
