This chimney set is compatible with most major sauna heater brands, including Leisurecraft, Narvi, HUUM, and Harvia. It features a 115 mm flue outlet, which fits the majority of sauna heaters. For Narvi heaters, a compatible adapter is required, as their outlet size differs.

The chimney has an 8" outer diameter, allowing for approximately 1-3/4" of insulation around the flue. This design supports safe installation, improved heat retention, and long-term durability across a wide range of sauna setups.

*Used on wood heaters with an outlet on the top of heater.
