ROTECTION
Install your stove on the following:
A non-combustible floor protector that you
obtain from your dealer, or any other
noncombustible material. A floor protector
is any noncombustible surface laid on the
floor underneath the stove that extends, 16
inches -US (or 46 cm in Canada)
beyond the
fuel loading door and 8 inches (20 cm)
beyond each side of the cook stove. (See
Figure 1) The hearth protection for your
Deva 100 must have an R-value of at least
0.89 or be a UL Listed floor protection.
An example of a non-combustible floor
protector would be a hearth constructed with a
continuous layer of a listed backer board (such
as Wonder-Board or Durock) used for ember
protection with a tile, brick, slate, or another
noon-combustible facing.
For horizontal chimney connector installations,
the floor protection must be installed beneath
the connector and 2” beyond each side.
Floor protector’s come with various types of
specifications. To convert a floor protector’s
specification to an R-value, do one of the
following:
•
If the R-value is given, use that value—
no conversion is needed.
•
If a K-factor is given with a required
thickness (T) in inches, use this formula:
R-value = 1/K x T
•
If a C-factor is given, use the formula:
R-value = 1/C
To determine the R-value of the proposed
alternate floor protector:
•
Use either the K-factor or the C-factor
formula explained above to convert
specifications not expressed as R-values.
•
For multiple layers of floor protectors,
simply add the R-values of each layer to
determine the overall R-value of the
layers.
If the overall R-value of your setup is greater
than the R-value of the specified floor protector,
then your setup is acceptable.

Please use this section to plan the layout
for your stove. Consider clearance of pipe
to combustibles and cookstove to
combustibles.
You must follow minimum clearances for the
Deva 100 cookstove to combustibles such as
walls and ceilings. You may reduce the general
clearances if installing the stove near
Protected
Surfaces
.
