completely noncombustible surface such as unpainted
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
noncombustible 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 extend under the chimney connector and 2” to
either side. Refer to Figure 12 for minimum noncom-
bustible 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 re-
quired 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 dimensions.
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
noncombustible 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
bottom 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
passes 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)
ST730
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 protection
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.
