8.2 Floor Protection
This stove is designed to prevent the floor from overheating. However, it must be placed on a
non-flammable surface to protect the floor from hot embers that may fall during loading. The
floor protection must be a continuous, non combustible material, such as steel with a minimum
thickness of 0.015" (0.38 mm) or ceramic tiles sealed together with grout. Cement board, brick,
or any other approved or listed material suited for floor protection. No R factor required.
A material is considered non-combustible when made entirely of steel, iron,
bricks, tiles, concrete, slate, glass or a combination of these materials.
Materials corresponding to ASTM E136 and UL 763 are considered to be
non-combustible materials with the exception of gypsum.
Any type of tile will require a continuous non combustible sheet beneath to prevent the possibility
of embers falling through to the combustible floor if cracks or separation should occur in the
finished surface. Check local codes for approved alternatives. No protection is required if the
unit is installed on a non-combustible floor (ex: concrete).
