Product Benefits

Loading a sauna stove means opening the door and letting the room's heat out, and carrying wood across a bench you have just cleaned. The Legend 150 SL solves both by moving the firebox door through the wall. The stove sits inside the sauna, the fire chamber extension pushes through a masonry opening, and you feed it from the changing room or from outside. It is a black steel wood burning sauna stove made in Finland, part number WK150LDSL, holding 264 lbs of stone and rated for rooms of 212 to 459 cubic feet.

The exterior feed is a build decision, not an accessory. Harvia requires an opening in a concrete or brick wall, at least 220 mm wide, at least 390 mm up from the floor, and through a wall no more than 150 mm thick. If your sauna wall is timber framed, or thicker than 150 mm, this stove cannot be installed as intended. Confirm the wall before anything else, because it is the single specification that rules the Legend 150 SL in or out.

Safety distances to combustible material are 19.69 inches at the front, 9.84 inches at the rear, 7.87 inches at each side, and 39.4 inches from the top of the stove to the ceiling. These are specific to the Legend and are not the same as any other Harvia stove, so do not reuse a figure from a different model. The floor must be non-combustible. A concrete slab of 60 mm or more takes the stove directly; a tiled or timber floor needs the WL100 protective bedding, because tile adhesive and grout are not heat resistant. An unshielded smoke pipe needs 19.69 inches to combustibles, or 9.84 inches with the WZ020130 radiation cover. Harvia also warns that the published distances only hold when the stones are stacked to its instructions. No North American listing is published for this stove, so check what your local authority requires before you commit.

• BEFORE YOU ORDER: CLEARANCES, FLOOR AND LISTING

Ideal For

Masonry-walled saunas where the feed can pass through the wall

Rooms of 212 to 459 cubic feet

Owners who want to load wood without entering the hot room

Off-grid cabins with no electrical supply to spare

NOT IDEAL FOR

Timber-framed walls. The feed tunnel needs concrete or brick

Walls thicker than 150 mm. The extension will not reach

Rooms that cannot give 19.69 inches of front clearance

Jurisdictions that require a North American listing on solid fuel

Chimney and flue

The connection opening is 115 mm and the flue pipe needs a minimum internal diameter of 110 mm, rated to chimney temperature class T600. The rear opening centres 560 mm from the floor. An upper connection needs a 45 or 90 degree angled pipe, set 180 mm from the stove. Harvia's datasheet lists the top connection only while the installation manual gives full procedures for both top and rear, so confirm with us which your room needs before you order pipe. Where the stove passes through a wall to a steel chimney, that non-combustible wall must run all the way to the roof.

Also Consider

For a bigger room, the Harvia PRO 20 range covers larger volumes. For a smaller room or a lower budget, the Harvia M3 is the classic box stove at 16.5 kW. If your walls rule out the exterior feed, ask us about the standard Legend 150.
