What is the Harvia WL500 protective sheath?
The Harvia WL500 is a one-sided protective sheath, a single black-painted steel panel, for Harvia Pro 20 wood-burning sauna stoves. Fitted on one side of the stove, it shortens the distance to a combustible wall on that side from 11.8" (300 mm) to 2.4" (62 mm).
Which stoves does the Harvia WL500 fit?
Harvia's sheath instructions name the WL500 for the Pro 20, Pro 20 SL, Pro 20 Duo, the 20 Boiler models and the Pro 20 LS and RS. It does not fit the Pro 20 ES, whose one-sided sheath is the WL600. For a stove in a corner or an alcove, the three-sided Harvia WL550 three-sided protective sheath covers the sides and rear of a Pro 20 or Pro 20 SL. Topture offers the WL500 as an option on the Harvia Pro 20, the Harvia Pro 20 SL, the Harvia Pro 20 LS and the Harvia Pro 20 RS.
How is the Harvia WL500 installed?
The Harvia WL500 is fitted to the stove following Harvia's illustrated instructions, under Documents. Leave at least the sheath-to-wall gap below between the sheath and the wall, and keep the stove's front distance, which grows with a sheath fitted. A sheath shortens the distances only on the sides it covers.
