FLOOR PROTECTION
NOTE: In Canada, fl oor protection
must extend 18" (450mm) to
the front and 8" (200mm) to
each side and back of the
stove.

How To Determine If Alternate Floor Protection Materials Are Acceptable
The specifi ed fl oor protector should be 3/8"
(18mm) thick material with a K - factor of
0.84.
The proposed alternative is 4" (100mm) brick
with a C-factor of 1.25 over 1/8" (3mm) mineral
board with a K-factor of 0.29.
Step (a):
Use formula above to convert specifi cation
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
specifi ed R of 0.893. Since proposed system
R is greater than required, the system is
acceptable.

A combustible fl oor must be protected by non-combustible material
(like tile, concrete board, or certifi ed to UL-1618 or as defi ned by
local codes) extending beneath the heater and a minimum of 6"
from each side and minimum 16" from the front face of the stove
and minimum 6" (or the rear clearance to combustibles whichever
is smaller) from the rear of the stove.
When installed with horizontal venting, non-combustible fl oor
protection must beneath the fl ue pipe and extend 2" (51mm)
beyond each side.
A minimum of a 1/2" thick thermal fl oor protector with a 0.84k
factor is required when installing the standard or optional short
legs. This applies to both Canada and the US. All other require-
ments (ie. hearth size) remain the same.
