HUUM Mounting Collar for HIVE Flow LS and HIVE Flow Mini LS Sauna Stoves

The HUUM Mounting Collar is a through-wall collar for the HUUM HIVE Flow LS wood-burning sauna stoves, where the firebox passes through the wall so you can load wood from outside the sauna room. It finishes the opening on both sides of the wall and gives the stove a smooth transition to the wall. It comes in two sizes: the Large (part number H3016022 in stainless steel) for the full-size HIVE Flow LS, and the Small (part number H3018022 in stainless steel, H3018032 in black) for the HIVE Flow Mini LS. You can choose a 2 mm stainless steel finish or a black finish made of heat-resistant coated aluminum. The collar adjusts for walls from 100 to 150 mm thick (depth 4" min / 150 mm max), and it is for non-combustible walls only. The stove and other accessories are sold separately. Includes an installation manual.

A finished look through the wall

A through-wall stove needs a clean, safe finish where the firebox goes through the wall. The collar is made of an inner flange, an outer flange, and a cover flange for the sauna-room side, so both faces of the wall are neatly covered. HUUM says it enhances the look of the stove and integrates it with a non-combustible wall. It does not replace the clearances and wall requirements in the stove's own manual.

Choose the right size and color

The Large collar (width 23.2" / 590 mm, height 24" / 610 mm) is for the full-size HIVE Flow LS. The Small collar (width 21.2" / 540 mm, height 24" / 610 mm) is for the HIVE Flow Mini LS. The two collars are not interchangeable. The standard HIVE Flow and HIVE Flow Mini stoves do not pass through a wall, so they do not use a collar. Both sizes come in stainless steel or black. If you use HUUM protective bedding under the stove, the plinth plate in the kit is used with it, and it changes the wall opening, so check the manual.

Installing the collar

According to HUUM's installation manual: check the wall opening dimensions for your model first. Remove the stove door, the door lock bushing, and optionally the grate. Place the stove on its protective bedding or the floor, and push it through the opening as far as possible. Assemble the inner flange inside the outer flange with the supplied fasteners, adjust it to your wall thickness, and tighten the nuts. Fix the flange with heat-resistant silicone, which is not included, or drill and fasten it with suitable screws. Refit the door and lock bushing, move the stove to its final position, and make sure the door opens freely and locks. Finally, attach the sauna-room cover with screws or heat-resistant silicone. The manual also says to make sure that no wall made of flammable material protrudes beyond the collar. Installation of the stove itself must follow its own manual and local code.

Why the HUUM Mounting Collar stands out

Load wood from outside

The collar finishes the opening where the firebox passes through the wall, so you can feed the stove from outside the sauna room.

Two sizes, two finishes

Choose Large or Small to match your stove, in 2 mm stainless steel or black heat-resistant coated aluminum to match your interior.

Adjusts to your wall

The inner flange slides inside the outer flange, so the collar fits walls from 100 to 150 mm thick (depth 4" min / 150 mm max).

Covers both sides of the wall

An inner flange, an outer flange, and a cover flange for the sauna-room side give a neat finish on both faces.

Works with protective bedding

A plinth plate is included for use with HUUM protective bedding. The bedding changes the wall opening, so the manual gives dimensions for both set-ups.

Made for the LS stoves

The Large collar is for the HIVE Flow LS and the Small collar is for the HIVE Flow Mini LS, so match the size to your stove before ordering. We are an authorized HUUM dealer.

IBIS Wheelchair to Car Lift

The IBIS wheelchair to car lift was a game changer for us. My husband has been in a wheelchair for more than 40 years and we have never seen anything like this in the US and had no idea such a lift exist existed.

My guy is hemiplegic and usually able to stand pivot into the car but he broke his femur in November 2025 and had to be non-weight bearing for 3 months. He lost so much strength and ability that he could no longer do any kind of safe transfer.

Our friend found the IBIS wheelchair to car lift online and we decided to take the risk. It was worth every penny and more. Within a day of its arrival we were mobile and in and out of the car again. It is very manageable for me to operate and in our 60’s we are grateful for anything that lightens our load.

Everything arrived as advertised. Customer service was outstanding with clear communication. I was provided help to ensure my measurements were correct and was offered a few options to customize the sling. We had to get a new car right after we bought the lift and it was a good fit in the new car.

We are very pleased and highly recommend this product.

Kelly Newton - Santa Barbara

It works very well

Annetta Voigt

I love the fact it installs along the side and does not have a huge footprint. It works great lifting scooter or wheel chair. Easy to use.

Fantastic Experience from Mediriser

Fantastic experience with Mediriser! We purchased a red light therapy bed and an HBOT machine. The customer service team was incredibly responsive throughout the entire process. Even when we hit a few unexpected bumps, they completely took ownership and went above and beyond to resolve them. Highly recommended for wellness equipment!
