Clearance diagram for installations
INSTALLATION
Side and Top facing is a maximum of 1.5" thick.
Floor protection must non-combustible, insulative
material with an R value of 1.1 or greater.
*
If the hearth extension is fl ush with the fl oor (F)
it must extend 19.5" in front of the body face
(E).
Note: Hearth Extension Width (G) is meas-
ured from edge of fuel door to side of
hearth.
** A non-combustible mantel may be installed
at a lower height if the framing is made of
metal studs covered with a non-combustible
board.

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 = 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.

Floor Protection
Please check to ensure that your fl oor protection
and hearth will meet the standards for clearance
to combustibles. Your hearth extension must be
made from a non-combustible material.
