500mm isolated extension to the Harvia Steel Chimney. Thanks to an ingenious mechanism, extensions are wound together and the smoke pipes are also equipped with slots to lock them together. This prevents movement caused by temperature changes.
The rated maximum temperature of combustion gases for a furnace connected to a steel chimney is 600 ºC. The external diameter of the steel chimney is 220 mm and the diameter of the smoke pipe is 115 mm. The safety distance to inflammable materials is 100 mm. The Harvia steel chimney has a CE-marking, so the product complies with all international fire- and operational safety requirements. The steel chimney is sootfire proof.
Always read the instructions for installation of the steel chimney and the attached furnace carefully!
