The HUUM Mounting Collar L is designed for use with the HIVE Flow LS Sauna Stoves. This collar enhances the aesthetic of your sauna stove and integrates the stove with a non-combustible wall.
On an LS stove the firebox passes through the wall so wood can be loaded from outside the sauna room. The collar is what makes that penetration look finished on both faces. The catalog lists SKU as the stainless steel collar.
The manual is unambiguous: “The mounting collar of HIVE Flow LS heaters is designed for installation through a NON-COMBUSTIBLE wall,” with the added warning “Ensure that the flammable material wall does not protrude.”

PLAN THE WHOLE SAUNA
Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
