EXAMPLE: The specified floor protector should be 3/4 inch thick material with a k-factor of 0.84. The proposed
alternate is 4" brick with a C-factor of 1.25 over 1/8" mineral board with a k-factor of 0.29.
Step A: Use formula above to convert specification to R-value.
R=1/k x T = 1/0.84 x .75 = 0.893
Step B. Calculate R of proposed system
4" brick of C = 1.25, therefore Rbrick =1/C=1/1.25 = 0.80
1/8" mineral board of k=0.29, therefore Rmin.bd. = 1/0.29
x 0.125=0.431
Total R=Rbrick + Rmineral board = 0.8 + 0.431 = 1.231
Step C: Compare proposed system R of 1.231 to specified R of 0.893. Since proposed system R is greater than
required, the system is acceptable.

The methods and parts to be employed for installing the room heater at reduced clearances (i.e. optional shields,
etc.)
If an insulated floor protector is required, the instruction must state the minimum R value and the requirement to
us a UL 1618 listed protector
CAUTION:
- Do not install this stove in closets or alcoves.
- Keep combustibles at least three feet from the stove. This includes furniture, magazines, rugs,
clothing, etc.
- Do not dry clothes on, or within, three feet of the stove.
- Do not store flammable liquids in the same room as the stove
