ROTECTION
Install your stove on one of the following:
A floor protector with an R-value of 0.8 or
more that you obtain from your dealer. A
floor protector is any noncombustible
surface laid on the floor underneath the
stove that extends, 16 inches -US (46 cm -
CA)
beyond the front door and 8 inches (203
mm) beyond each side of the fuel loading
and ash removal opening(s).
For horizontal chimney connector installations,
the floor protection must be installed beneath
the connector and 2” beyond each side. To
determine the R-value of the proposed alternate
floor protector, 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.

An outside air source may be connected
directly to this stove using an optional outside
air kit (HearthStone part #93-53700). The
advantage of providing outside air directly to
the stove is that the air used by the stove for
combustion is taken from outside of the
residence rather than from within the room
where the stove is located. With outside air
supplied directly to the stove, drafts within the
room and air infiltration within the building are
reduced. Use of the outside air kit may also
improve stove performance in a particularly
airtight house.
The outside air kit for this stove allows
for the direct connection of the stove's air intake
to a minimum 3" (76 mm) diameter duct
(supplied by others) which leads to the outside
of the house. When considering placement of
the duct from the outside of the house to the
hearth, keep in mind the need to avoid structural
members of the house. The termination of the
duct on the outside wall of the house should be
located in such a manner so as to preclude the
possibility of obstruction by snow, leaves or
other material and should be screened against
animals and insects.
