HUUM HIVE Wood LS 17ST Pkg HIVE Wood Series 17kW LS Sauna Heater Package
The HUUM HIVE Wood LS 17ST Package bundles the 17kW HIVE Wood LS 17 wood-burning sauna stove with 287 lbs of sauna stones (9 x 33-lb boxes) included - the complete stone requirement for the stove, arriving together in a single pallet order. LS identifies the through-wall firebox configuration: the firebox bushing passes through the sauna wall, wood is loaded and the fire is managed from an adjacent room or outdoors, and the tempered glass door faces the adjacent space for a fireplace view throughout the session. Bathers inside the sauna are completely undisturbed - the sauna door stays closed from start to finish. The package simplifies first-time purchase by combining stove and stones in one order. The chimney connection remains separate: HUUM offers Thru-Ceiling, Thru-Wall, and Barrel chimney kits for different installation configurations. The HIVE Wood LS 17 is built on HUUM's stone-primary philosophy: use as little metal as possible so heat comes mainly from the stones and very little from the metal surfaces. The 5mm stainless steel flame tamer, stainless steel body and furnace door, and natural oil surface finish are standard across the HIVE Wood platform. Top flue connection only, 115mm. 6" North American adapter required and sold separately. Non-combustible wall required for the LS firebox bushing. CE certified. 5-year limited warranty. Designed and precision-crafted in Estonia by HUUM.
LS through-wall firebox - stove and stones together, session undisturbed
The HIVE Wood LS 17ST Package combines the LS exterior-feed stove with its full 287-lb stone requirement in one order. The LS configuration is the defining feature: the firebox bushing passes through the sauna wall so all wood loading and fire management happen from outside the sauna room at all times. The tempered glass door faces the adjacent room, providing the person tending the fire a direct view of the flames. Bathers inside receive 17kW of heat and the steam from 287 lbs of stones without the sauna door opening. HUUM's description of the LS advantage is direct: it allows you to heat the sauna from an adjacent room. Having 287 lbs of stones arrive with the stove means the installation can be completed and the stove loaded in a single process, ready to fire as soon as the chimney connection is in place. The chimney kit is selected separately to match the specific installation routing.
287 lbs of stones - stone-primary heat, long-lasting steam
HUUM's design philosophy for the HIVE Wood is explicit: use as little metal as possible so that the heat comes mainly from the stones and very little from the metal surfaces. This maximises the good negative ions released by the stones and keeps the positive ions from the metal at a minimum. At 287 lbs (9 x 33-lb boxes, 5-10 cm), the HIVE Wood LS 17's stone load is one of the largest in the residential wood-burning sauna stove market. HUUM's own description: the large number of exposed stones provides long-lasting heat and better steam capability. For an LS installation where the fire is loaded from outside and then left to burn through naturally, the stone thermal mass is what sustains the session quality - the stones hold and radiate heat steadily after the fire dies, without requiring the bathers inside to interact with the stove.
Non-combustible wall required - critical LS installation note
The LS firebox bushing must pass through a non-combustible wall - stone, concrete, or similar - per the HUUM installation manual. A combustible wood-framed wall is not suitable for the LS bushing without modification. Mineral wool insulation is recommended around the bushing passage. At least 0.4 in (10mm) of air gap must be maintained between the bushing and the stove body. HUUM's installation manual also specifies that the LS stove's protective bed plate beneath the stove should be extended toward the wall and that the non-combustible floor surface should extend under the stove and across the bed plate area. A licensed chimney professional is recommended for all flue installations and for advising on the specific wall penetration configuration.

Why the HUUM HIVE Wood LS 17ST Package stands out
Stove and 287 lbs of stones together - LS installation ready
The LS 17ST Package includes the HIVE Wood LS 17 stove and its full 287-lb stone requirement (9 x 33-lb boxes) in a single order. For a first-time LS installation, the stones are a required purchase - and ordering separately adds coordination steps. The package resolves this: both arrive on the same pallet delivery, and the stove can be fully loaded immediately after installation without waiting for stones. The chimney kit is selected separately to match the specific building configuration (Thru-Ceiling, Thru-Wall, or Barrel), ensuring the correct routing kit for every installation.
LS exterior loading - session undisturbed from first fire to last
The HIVE Wood LS 17's firebox extends through the sauna wall so wood is loaded and the fire is tended entirely from outside the sauna at all times. The sauna door stays closed throughout the session. No heat is lost to wood loading. Bathers inside are completely undisturbed. The tempered glass door faces the adjacent room, giving the person managing the fire a direct view of the flames throughout. HUUM's description of the LS experience: the extended firebox allows you to heat the sauna from an adjacent room. For a cabin sauna with an adjoining lounge or changing room, or a sauna building where fire management from outdoors is preferred, the LS configuration is the purpose-built specification.
287 lbs of stone-primary heat - sessions sustained after the fire
The stone-primary philosophy is the foundation of the HIVE Wood platform: minimal metal so heat comes mainly from stones. At 287 lbs (9 x 33-lb boxes), the stone load accumulates heat throughout the fire and holds it steadily after the fire dies. For an LS installation where the fire is loaded from outside and left to burn through naturally without reloading, the stone thermal mass is what carries the session. HUUM's description: the large number of exposed stones provides long-lasting heat and better steam capability. All 287 lbs arrive in the package - the stove is loaded and ready to fire as soon as the chimney connection is in place.
5mm flame tamer and natural oil finish - built for long-term use
The HIVE Wood LS 17's flame tamer is built from 5mm (0.20 in) thick stainless steel - HUUM identifies it as the most sensitive component of the wood-fired stove and builds it at 5mm specifically for durability under sustained high-temperature flame contact. For a stove used regularly across many seasons in a cabin or cottage sauna, the 5mm flame tamer is a key long-term advantage. The stainless steel body and furnace door are treated only with natural oils - no paint or synthetic coatings - keeping the material character consistent with HUUM's broader philosophy of minimal processing throughout the stove.
LS installation requirements - non-combustible wall and correct chimney kit
The LS firebox bushing must pass through a non-combustible wall per the HUUM installation manual - stone, concrete block, or equivalent. This is a firm requirement. A combustible wood-framed wall is not suitable for the LS bushing passage without modification to create a non-combustible surround. Mineral wool insulation around the bushing and a minimum 0.4" (10mm) air gap between the bushing and the stove body are required. The flue connection on the LS model is top-only - unlike the standard HIVE Wood 17 which offers top or back connection. A licensed chimney professional is recommended for advising on the wall penetration configuration and for all flue installation work.

Manuals and Documents
Warranty
5-year limited warranty
The HUUM HIVE Wood LS 17 carries HUUM's 5-year limited warranty from the date of purchase. The warranty covers defects in manufacturing and materials under normal use and maintenance conditions. The warranty does not cover damage caused by improper installation, failure to follow the installation and operating guidelines in the manual, use of unsuitable sauna stones (decorative stones must not be used as they can break under heat), operating without the required stone load, chimney-related damage from inadequate maintenance, or improper preparation of the LS wall penetration (non-combustible wall required). Removing the stones once per year for inspection, replacing any broken stones or stones with calcium deposits, and re-inserting carefully are required maintenance tasks. A licensed chimney professional is recommended for all flue installation and regular chimney sweep maintenance. Proof of purchase from an authorized HUUM dealer is required for warranty claims.
