Harvia Extension for chimney 500 mm black

Thanks to an ingenious joint mechanism, the supplementary parts are wound together and the smoke pipes are locked in place by the grooves on them. This prevents movement caused by temperature changes. Indoors, the chimney can be installed up to a height of 3 meters without support. Outdoors, the corresponding self-supported installation height is 2 meters. Choose top-of-the-line Harvia quality.
