Description

What is the Harvia Legend 150 SL wood-burning sauna stove?

The Harvia Legend 150 SL (WK150LDSL) is a 16 kW wood-burning sauna stove for sauna rooms of 212 to 459 cu ft, loaded from the next room: its fire chamber extends through the wall, so firewood and ash stay outside the sauna. It stands on the floor on adjustable legs, holds up to 264 lb (120 kg) of 4–6" stones inside a round black steel frame, and connects to the chimney at the top only, through a 4.5" (115 mm) opening. It needs no electrical connection.

The Harvia Legend 150 is the same stove loaded from inside the sauna, with a top or rear connection; the Harvia Legend 240 SL is the larger through-the-wall Legend. The Harvia Legend collection and the Harvia wood-burning stove collection have every Harvia wood-burning stove Topture sells.

Specifications

Does the Harvia Legend 150 SL fit my sauna?

The Harvia Legend 150 SL heats sauna rooms of 212 to 459 cu ft (6–13 m³). Harvia's manual adds 1.2 m³ for every square meter of uninsulated brick, glass block, glass, concrete or tile wall, about 3.9 cu ft per sq ft, and a glass door counts: its example is a 10 m³ room with a glass door, which needs the output of a 12 m³ room. Multiply the volume of a solid-log sauna by 1.5. Harvia's data sheet gives a minimum sauna room height of 68.9" (1,750 mm), and the top of the stove needs at least 39.4" (1,000 mm) to the ceiling.

Installation

How is the Harvia Legend 150 SL installed?

The Harvia Legend 150 SL stands on a floor strong enough to carry it and its stones, on its adjustable legs, inside the safety distances below, and connects to a T600 chimney. Harvia's manual says all local regulations apply, that the stove is not suitable for a shared flue, and that the local fire authorities can give detailed fire-safety requirements. Harvia's installation manual, under Documents, gives the step-by-step installation and the chimney connection.

What wall opening does the Harvia Legend 150 SL need?

The Harvia Legend 150 SL is loaded from the room next to the sauna: its fire-chamber extension passes through an opening in a concrete or brick wall. Harvia's manual gives the opening as at least 8.7" (220 mm) wide, with its bottom at least 15.4" (390 mm) above the floor, in a wall no thicker than 5.9" (150 mm); the opening changes if protective bedding is used under the stove. The chimney connects at the top only.

Does the Harvia Legend 150 SL need floor protection?

It depends on the floor under the Harvia Legend 150 SL. A bare concrete floor at least 2.4" (60 mm) thick needs no protection. A tile floor needs Harvia protective bedding or similar heat-radiation protection, because the adhesives and waterproofing under tile do not resist the stove's heat. A floor made of combustible material needs the bedding too, plus non-combustible floor protection in front of the stove door on the loading side. Harvia's Legend manual names the WL100 Legend protective bedding; the Harvia WL100 protective bedding (Protective Bedding SM) is sold separately and does not come with the stove.

Harvia Legend 150 SL safety distances

Keep at least these distances between the Harvia Legend 150 SL and anything that can burn. Harvia's distances assume the stones are piled so that they cover the stove body.

Harvia Legend 150 SL minimum safety distances (Harvia manual Y05-0136 09/25)
Top of the stove to the ceiling	39.4" (1,000 mm)
Sides to combustible material	7.9" (200 mm)
Rear to combustible material	9.8" (250 mm)
Front to combustible material	19.7" (500 mm)
To a masonry wall	2.0" (50 mm) if air can circulate in front and at one side; 3.9" (100 mm) in a recess

Harvia Legend 150 SL with the WL200 protective sheath and WL300 smoke-pipe cover (Harvia manual Y05-0136 09/25, figure 10)
Side wall to the WL200 sheath	1.2" (30 mm)
Rear wall to the WL200 sheath	1.2" (30 mm)
Gap between the WL200 sheath and the stove	2.0" (50 mm)
Rear wall to the WL300 smoke-pipe cover	6.5" (165 mm)

Harvia Legend protection supplies drawing: distances A 30 mm, B 30 mm, C 50 mm and D 165 mm with the WL200 sheath and WL300 smoke-pipe cover

The shorter distances apply only with the sheath and cover fitted; without them, use the first table.

Connecting the Harvia Legend 150 SL to a chimney

The Harvia Legend 150 SL connects at the top through a 4.5" (115 mm) opening, to a chimney of temperature class T600 with a flue at least 4.3" (110 mm) across; it cannot share a flue with another fireplace. The Harvia WHP1500 chimney kit (sold separately) fits the top opening, and its page gives the roof and clearance requirements. For North American 6" chimney pipe, the Harvia WZ115155 pipe adapter (sold separately) adapts the opening.

Frequently Asked Questions

What comes with the Harvia Legend 150 SL, and what else does it need?

The Harvia Legend 150 SL ships as the wood-burning stove, with its fire-chamber extension, glass door, ash box and adjustable legs, and Harvia's installation and user manual. It needs no electricity, but it does need up to 264 lb (120 kg) of 4–6 in sauna stones, which six 44 lb boxes of Harvia AC3020 cover, a T600 chimney such as Harvia's WHP1500 kit, and, on a tile or combustible floor, Harvia's WL100 protective bedding. None of these come with the stove: Topture sells the stones, the WHP1500 chimney, the WL100 bedding, the WL200 sheath, the WL300 smoke-pipe cover, the WP250LD water heater and the SASPO241 safety railing separately.

What size sauna does the 16 kW Harvia Legend 150 SL heat?

The Harvia Legend 150 SL is rated at 16 kW and heats sauna rooms of 212 to 459 cu ft (6–13 m³), according to Harvia's manual. Harvia adds 1.2 m³ for every square meter of uninsulated brick, glass, tile or concrete surface, about 3.9 cu ft per sq ft, and counts a glass door: a 10 m³ room with a glass door needs the output of a 12 m³ room. Multiply a solid-log sauna's volume by 1.5. Harvia's data sheet gives a minimum room height of 68.9 in (1,750 mm), with at least 39.4 in (1,000 mm) above the stove. The Legend 240 SL is the larger through-the-wall Legend, for up to 848 cu ft.

What wall opening does the Harvia Legend 150 SL need?

The Harvia Legend 150 SL needs an opening in a concrete or brick wall for its fire-chamber extension, so it is loaded from the room next to the sauna. Harvia's manual gives the opening as at least 8.7 in (220 mm) wide, with its bottom at least 15.4 in (390 mm) above the floor, in a wall no thicker than 5.9 in (150 mm); the opening changes if protective bedding is used under the stove. On a combustible floor, non-combustible floor protection goes in front of the door on the loading side.

What chimney does the Harvia Legend 150 SL need?

The Harvia Legend 150 SL needs a chimney of temperature class T600 with a flue at least 4.3 in (110 mm) across; it connects at the top only, through a 4.5 in (115 mm) opening, and Harvia's manual does not allow a shared flue. Harvia's WHP1500 steel chimney kit, in stainless or black, joins the top opening with a smoke pipe cut to length; it suits roofs pitched 10° or more (a flat roof needs the WHM24 rain flange) and is CE marked to EN 1856-1. Keep its insulated casing 3.94 in and its uninsulated smoke pipe 19.7 in from anything that can burn. A masonry T600 flue is the alternative.

How is the Harvia Legend 150 SL installed, and does it need electricity or floor protection?

The Harvia Legend 150 SL stands on a floor strong enough to carry it and its stones, on adjustable legs, with its fire-chamber extension through the wall, and needs no electrical connection. A bare concrete floor at least 2.4 in (60 mm) thick needs no protection; tile needs Harvia protective bedding because the adhesives and waterproofing under tile do not resist the heat, and a combustible floor needs the bedding plus non-combustible protection in front of the door on the loading side; Harvia's Legend manual names its WL100 bedding. Keep the stove 39.4 in from the ceiling, 7.9 in at the sides, 9.8 in at the rear and 19.7 in in front from combustible material; with Harvia's WL200 sheath fitted, it can stand 1.2 in (30 mm) from a combustible side or rear wall.

What has to be done before the first fire in a Harvia Legend 150 SL?

Harvia's manual says to heat the Harvia Legend 150 SL outdoors first if possible, with the smoke pipes fitted for draught, until the protective paint stops smoking; then let it cool and brush and vacuum off any paint residue. Install the stove, load the stones and heat the sauna to a normal bathing temperature with good ventilation, because the stove may still smoke and smell a little. Once the smoking stops, it is ready for normal use.

What firewood does the Harvia Legend 150 SL burn, and how hot should the sauna get?

The Harvia Legend 150 SL takes firewood up to 13.8 in (350 mm) long and 3.1–5.9 in (8–15 cm) across, and Harvia declares loads of about 6 lb (2.7 kg) to light the fire and 7 lb (3.2 kg) per refuelling. Empty the ash box before each firing. The stove has no thermostat, so the fire sets the heat: Harvia's rule of thumb is that a sauna over 212°F (100°C) is too hot, and several full loads of wood in a row overheat the sauna, the stove and the chimney and can start a fire.

What problems do Harvia Legend 150 SL owners run into, and how are they avoided?

Most problems Harvia's manual lists for the Harvia Legend 150 SL trace back to the chimney, the wood or the stones. Smoke in the sauna or no draught points to a leaking flue connection, a cold flue, an extractor fan pulling air, a full ash box or blocked smoke canals. A sauna that will not heat is usually too big for the stove, has uninsulated walls or is fired with damp wood; stones that stay cool are often smaller than 4 in or broken. A smell on the first firings is the paint curing, and wooden walls darkening over time is normal. Rearrange the stones at least once a year and have the chimney swept regularly.

Who makes the Harvia Legend 150 SL, and what is it made of?

The Harvia Legend 150 SL (WK150LDSL) is made by Harvia, the Finnish sauna manufacturer. It has a round black steel frame around a steel stove body with a fire-chamber extension, a glass door with a chrome handle and an ash box, and it is CE marked to EN 15821. It measures 20.9 in wide, 28.7 in deep with the extension and 29.1–30.3 in high, and Harvia's data sheet gives its weight as 143.5 lb (65.1 kg) without stones.

What warranty does the Harvia Legend 150 SL have?

Harvia's manufacturer warranty covers the Harvia Legend 150 SL for 2 years of family use. The extra registration year Harvia offers applies to electric heaters only, not to wood-burning stoves, and sauna stones are not covered; the warranty also excludes damage caused by stones Harvia does not recommend. Harvia US Inc. is the warrantor in North America. Topture is an authorized Harvia retailer and assists with troubleshooting and warranty coordination.

How does the Harvia Legend 150 SL compare with the Legend 150, the M3 SL and the Legend 240 SL?

The Harvia Legend 150 SL is loaded from the next room, so firewood and ash stay out of the sauna, and it holds 264 lb of stones for soft, lasting heat. The Legend 150 is the same 16 kW stove loaded from inside the sauna, with a top or rear connection. The M3 SL is a through-the-wall stove for the same 212–459 cu ft that holds 66 lb of stones in a compact black body. The Legend 240 SL is the 21 kW through-the-wall Legend for rooms up to 848 cu ft, with 440 lb of stones.

Where can you buy the Harvia Legend 150 SL from an authorized dealer?

Topture is an authorized Harvia retailer and sells the Harvia Legend 150 SL with AC3020 stones, the WHP1500 chimney, WL100 bedding, the WL200 sheath, the WL300 smoke-pipe cover and the WP250LD water heater as options. Topture adds Lifetime Expert Support, help with troubleshooting and warranty coordination, free shipping on orders over $200 within the continental US, financing through Shop Pay Installments at checkout, and a 30-day return window.

What does a Harvia Legend 150 SL cost in total, delivered?

The delivered cost of a Harvia Legend 150 SL from Topture is the stove price plus the parts it needs: six boxes of AC3020 stones, a chimney such as the WHP1500 kit, and, on a tile or combustible floor, protective bedding. Topture has free shipping on orders over $200 within the continental US, so a Legend 150 SL order ships free there; Harvia stoves travel on a pallet by freight, with Topture's full-value freight protection. Budget separately for installing the chimney. Compare delivered totals, because some listings price the stove without its stones and chimney. Financing is available through Shop Pay Installments at checkout.

General Topture Questions

Where are you located, and where do you ship from?

Topture is an online retailer serving customers in the contiguous United States. The company is Topture LLC, a Wyoming limited liability company, and its registered business address is 30 N Gould St, Ste N, Sheridan, WY 82801.

Orders ship from manufacturer and distributor warehouses in the U.S. and Canada, and some products ship directly from the manufacturer in Europe. Each product page shows its estimated delivery time.

How much is shipping?

Orders over $200 ship free within the continental United States. Orders under $200 carry a small shipping fee.

Two exceptions: SaunaLife and ThermaSol products carry a freight charge at any order value, and sauna stones ordered without a heater ship at $60 per box because of their weight.

Every charge is shown at checkout before you pay.

Do you provide financing?

Absolutely! To view your financing offer, simply select Shop Pay Installments as your payment method at Step 3 of checkout.

You'll need to enter a debit card to receive your offer, but don’t worry—you can still back out before completing the purchase.

How long will it take for my items to arrive?

If your order is in stock, most orders ship within 2–7 business days of purchase. Transit time then depends on the distance from the warehouse and, for freight, on booking a delivery appointment.

For custom, pre-order or made-to-order items, the estimated delivery time frame is listed on the product page. Delivery dates are estimates, so please don't book installation labor until your order has arrived and been inspected.

What happens after I place my order?

As soon as you place your order, you'll receive a confirmation email with your order details—be sure to keep it for your records. Once your order ships, you'll receive another email with tracking information.

For freight deliveries, the carrier will call or text you to schedule an appointment once the shipment reaches their local terminal. Someone needs to be there to inspect the shipment and sign for it. Smaller parcels arrive by UPS or FedEx without an appointment.

Is there a warranty?

Yes. Products purchased through Topture include the applicable manufacturer’s warranty, subject to the manufacturer’s terms. You’ll find the warranty details for each product under the "Warranty" tab on its product page, and we help with troubleshooting and warranty coordination if an issue comes up.

Do you have a showroom?

We don’t have a showroom — we sell online. Our team is available by phone, email and chat to help you compare models, sizes and heaters, and we can send dimensions, installation manuals and electrical requirements before you buy.

Where do you deliver to?

Alaska, Hawaii, Puerto Rico, other U.S. islands and Canada are quoted separately, depending on the brand and model. We can't ship freight or oversized items to P.O. boxes.
