Permanent chimney base is produced in range of 150-350 mm of intake pipes. It is made of acid-resistant steel. The elements of the base are connected permanently. Ring chimney base can be used for tips of chimney channels that exhaust fumes from gaseous heating devices with the temperature up to 150°C and for ventilation channels to improve the chimney draft, thanks to the vacuum build by the base in a chimney channel. It also forms a protection of the exhaust channel from rain, snow or birds.
