FLOOR PROTECTION REQUIREMENTS
1. All Country Flame freestanding catalytic woodstoves require a listed floor protector that is noncombustible.
Country Flame catalytic stoves were tested with a listed floor protection that had a thermal conductivity of K =
0.85 BTU-inch per hour per square foot per degree Fahrenheit and that was 3/8” thick (9.5mm) non-asbestos
millboard. Refer to FIGURE 4 and TABLE 4 for floor protector information.
FIGURE 4: FLOOR PROTECTOR DIMENSIONS
NOTE: Chimney connectors must have 2 inches of floor protection from all sides in all direction.

TABLE 3: FLOOR PROTECTOR, IN INCHES, REFERS TO FIGURE 4
2. If a floor protector, different from the tested floor protector, is to be used, it must meet or exceed the requirements of
the listed R-value of the tested floor protector. To convert alternate floor protectors to their respective R value use the
following procedures:
a. Convert floor material specification to R-value.
i. R-value is given – no conversion is required.
ii. k-factor is given with required thickness (T) in inches: R = (1/k) x T.
iii. C-factor given: R = 1/C.
b. Determine the R-value of the proposed alternate floor protector.
i. Use the formulas provided in STEP 2 to convert values not expressed as “R.”
ii. For multiple layers of material, add each R-value of each layer to determine the materials overall R-
Value.
