B. Calculating Alternate Floor Protection Material
Thermal Conductivity: k value
The k value indicates the amount of heat (in BTU's) that will fl ow
in 1 hour through 1 square foot of a uniform material 1 inch thick
for each degree (F) of temperature difference from one side of
the material to the other. The LOWER the k factor means less
heat is being conducted through the non-combustible material to
the combustible material beneath it. The k value of a material
must be equal or smaller then the required k value to be accept-
able.

Thermal Resistance: R value
The R value is a measure of a material's resistance to heat trans-
fer. R value is convenient when more than one material is used
since you can add the R values together, whereas you can not
do this for k value. The HIGHER the R factor means less heat
is being conducted through the non-combustible material to the
combustible material beneath it. The R value of a material must
be equal or larger then the required R value to be acceptable.
Converting k to R:
Divide 1 by k and multiply the results times the thickness in inch-
es of the material.
R = 1/k x inches of thickness
Converting R to k:
Divide the inches of thickness by R.
k = inches of thickness/R
Calculations:
Example: Floor protection requires k value of 0.84 and 3/4 inch
thick.
Alternative material has a k value of 0.6 and is 3/4 inch thick.
Divide 0.6 by .75 = k value of 0.80. This k value is smaller than
0.84 and therefore is acceptable.
C. Outside Air Kit Installation
31M-ACC-MBK & 31ST-ACC
A source of air (oxygen) is necessary in order for combus-
tion to take place. Whatever combustion air is consumed
by the fi re must be replaced. Air is replaced via air leakage
around windows and under doors. In homes that have tightly
sealed doors and windows, an outside air source is needed.
An optional Outside Air Kit is available.
Included in OAK-ACC:
Termination cap, (2) wire ties, flex
adapter, and fasteners
Included in SRV7033-041:
Items Needed for Installation (not supplied)
• 4 inch fl ex aluminum pipe, or if using alternate material,
then it shall be made from durable, non-combustible,

Cover plate and sealing rope (see
Floor Installation Alternative below,

heat resistant material up to 350
required length for your installation.
• Phillips head screw driver
• Silicone sealant
• Drills and saws necessary for cutting holes through the
wall or fl ooring in your home.
1. Remove all materials from packing box.
2. Using a #2 Phillips screw driver attach the fl ex adapter to
the stove using 4 screws. Figure 14.1
3. For fl oor installations, remove circular" knock-out" in the
base of the pedestal.
4. Floor & Rear Installation: Cut a 4 inch (102mm) hole in
outside wall or fl oor to accommodate outside air piping.
Use 4 inch (102mm) aluminum metal fl ex or rigid piping
to directly connect outside air to appliance intake. Use
the supplied termination cap with a rodent screen. Seal
between the wall (or fl oor) and the pipe with silicone to
prevent moisture penetration.
5. Floor Installation Alternative: In some instances you
may not be able to install the fl ex pipe as shown in Figure
14.1. If that is the case, you will need to order SRV7033-
041 which includes a cover plate and sealing rope as
shown in Figure 14.2. The goal is to seal the pedestal
so no room air can leak into the pedestal or for cold air
infi ltration.
For Floor Installa-
tions Remove
Circular "Knock-Out"
in Base of Pedestal.
