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.\u003c\/p\u003e\n\u003ch4\u003eA finished look through the wall\u003c\/h4\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003ch4\u003eChoose the right size and color\u003c\/h4\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eInstalling the collar\u003c\/h4\u003e\n\u003cp\u003eAccording 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cp-hook\"\u003eThrough-wall mounting collar for HUUM HIVE Flow LS (Large) and HIVE Flow Mini LS (Small) wood-burning sauna stoves. 2 mm stainless steel or black heat-resistant coated aluminum.
