Vinyl Flooring
Vinyl Flooring is sensitive to heat. A 14 inch minimum
depth hearth extension is recommended when using vinyl
flooring up to the wall. See Figure 3.8.
NOTICE: Clearances that do not meet the minimum
guidelines could result in damage or buckling to the vinyl
flooring and is done at the installer's risk.
Hearth & Home Technologies does not recommend adhe-
sive based vinyl flooring due to thermal expansion. Float-
ing-style flooring can be used, but will reach temperatures
up to 110°F in a room with ambient temperature of 70°F.
Consult flooring specifications to ensure compatibility.
