concrete over earth may be used without the heat
shield.
Even when the bottom heat shield is installed, you must
provide special protection to the floor beneath. For
installation with the heat shield attached, use a non-
combustible floor protector such as 1/4” non-asbestos
mineral board or equivalent, or 24 gauge sheet metal.
The floor protector may be covered with a decorative
noncombustible material if desired. Do not obstruct the
space under the heater.
Protection requirements vary somewhat between the
United States and Canada as follows:
U.S. Installations:
The floor protector is required under
the stove and must extend at least 16” from the front
and left (loading door) side of the stove, and at least 6”
from the right side and rear. (Fig. 12) It must also ex-
tend under the chimney connector and 2” to either side.
Refer to Figure 12 for minimum noncombustible floor
protection dimensions.
To meet these requirements, a floor protector must be
at least 48” wide and 42” deep.
In Canada:
a noncombustible floor protector is required
under the heater also. The floor protector must extend
18” (457mm) from the front and left (loading door) side
of the stove, and at least 6” (150mm) from the right
side and rear. (Fig. 12) It must also extend under the
chimney connector and 2” to either side. Refer to Figure
12 for minimum noncombustible floor protection dimen-
sions.
In addition, a pad measuring 18” (457mm) wide by
24” (610mm) long consisting of 1/2” (13mm) thick rigid
insulation board with a K value of .23 or less (such as
Carborundum Duraboard LD or Manville Ceraform 126)
is also required; it must be centered and must extend
16” (406mm) in front of and 8” (203mm) under the unit.
The floor protector may be covered with a noncombus-
tible decorative material if desired. Do not obstruct the
space under the heater.
To meet these requirements, a floor protector must be
50” (1270mm) wide and 44” (1118mm) deep.
Due to the side loading door, floor protector require-
ments call for more protection on the left side than on
the right. If you wish a more balanced look, increase
the other side of the hearth as well.
Do not reduce
side protection under any circumstances.
NOTE:
In both the United States and Canada, no bot-
tom heat shield is required when the optional pedestal
base is used in place of the standard legs.

Floor Protection for Fireplace
Do not assume that your fireplace hearth is completely
noncombustible. Many fireplace hearths do not satisfy
the “completely noncombustible” requirement because
the brick or concrete in front of the fireplace opening is
supported by heavy wood framing. Because heat pass-
es readily through brick or concrete, it can easily pass
through to the wood. As a result, such fireplace hearths
can be a fire hazard and are considered a combustible
floor. (Fig. 13)

Combustible supporting timbers may lie beneath
fireplace hearths; such situations require additional floor
protection.
Wood Framing
For all fireplace installations, follow the floor protec-
tion guidelines described above. Keep in mind that
many raised hearths will extend less than the required
clearance from the front of the heater. In such cases,
sufficient floor protection as described above must be
added in front of the hearth to satisfy the minimum
floor protector requirement from the front of the stove:
16” (406mm) in the United States and 18” (457mm) in
Canada.
