Description
A wood-burning stove has to stand a set distance from anything that can burn, and in a small sauna that clearance is often the thing that decides whether the stove fits at all. A protective sheath is a shielded panel that mounts on the stove itself and cuts the required distance — the difference between a stove that fits your room and one that does not.
Check the clearance table in your stove’s manual before you build the benches. Retrofitting a sheath is easy; moving a bench because the stove had to shift four inches is not.
One side. A single flat panel — under four inches deep — for the one wall that is too close. Harvia approves it for the Pro 20, 20 SL, 20 Duo and the 20 RS/LS. If more than one side is tight, the WL550 wraps the stove instead.
