Extension for WHP1000 steel chimney

The Harvia WHP1000 steel chimney extension, made of stainless steel, makes it easy to extend the Harvia steel chimney. Thanks to the clever hinged mechanism, additional parts coil together,
and the smoke pipes are secured with grooves on them. This prevents movement caused by temperature changes.

Indoors, the chimney can be installed at a height of up to 3 meters without support. Outdoors, the corresponding installation height without support is 2 meters.
