Sauna Wood Stove Chimney Kit

DESCRIPTION

The Harvia chimney is an easy-to-install stylish chimney solution. The steel chimney withstands extensive changes in temperature and has mainly been designed for use with woodburning stoves, smaller fireplaces, and iron stoves in detached sauna buildings.

The standard delivery of the steel chimney includes a steel chimney and a utility box with a rain cap, a rubber rain flange and an installation set for rain flange, a stainless steel lead-through flange for the ceiling, a lead-through insulation and protector. The package also includes a non-isolated smoke pipe. Supplementary parts are available as accessories for this stainless steel chimney. Thanks to an ingenious mechanism, the supplementary parts are wound together and the smoke pipes are also equipped with slots to lock them together.

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 8.66″ and the diameter of the smoke pipe is 4.53″. The safety distance to inflammable materials is 3.94″.
