All HUUM wood-burning sauna stoves are equipped with standard European exhaust piping that measures at 4.5 inch (115 mm). This adapter is required for North American 6 inch (155 mm) piping conversion.
 
A sauna stove chimney pipe adapter serves as a connector or transition piece, linking a wood stove or heating appliance to a chimney flue or vent pipe. Typically crafted from metal, such as stainless steel or galvanized steel, it securely fits around the stove’s flue pipe and the chimney flue or vent pipe.
