The HUUM Thru-Ceiling Chimney Kit 108.3" is a chimney kit for HUUM sauna stoves that carries exhaust straight up from the stove through the ceiling and roof. It pairs single-wall and double-wall sections on a 120 mm chimney diameter, a layout meant to support safe exhaust flow and a reliable draft while keeping heat under control.
Supplied with a welded chimney base, a 1 m single-wall pipe, 0.5 m and 1 m double-wall sections, a rafter attachment, rain collar and chimney cap. The roof penetration component suits roof inclinations of 0–20°, and a two-part cover plate finishes the opening in the ceiling.
