Protect one side of your Harvia M3

The WL400 is the model-specific one-sided protective sheath for Harvia M1, M2, M3 and M3 SL wood-burning stoves. The black painted-steel panel mounts to either side of the stove.

Choose left or right protection. Keep at least 1.97 in from the outside of the fitted panel to combustible material on that side, in addition to the stove-to-panel mounting space. The opposite side and rear retain their unprotected clearances. Front, ceiling and chimney requirements remain separate.

For M3 SL with WL400, use a concrete or brick feed wall no thicker than 4.92 in. Thicker walls need Harvia confirmation for this sheath installation. The panel does not replace the noncombustible feed wall or loading-side floor protection.

The WL450 three-sided sheath and WL100 protective bedding are separate products.

Included

One-sided protective sheath. Stove, stones, floor bedding and chimney are not included.
