A flush-mounted sheet metal cover may be used on one
side only. If covers must be used on both sides, each
cover must be mounted on non-combustible spacers
at least 1” (25 mm) clear of the wall. Your Dutchwest
dealer or your local building inspector can provide de-
tails of other approved methods of passing a chimney
connector through a combustible wall. In Canada, this
type of installation must conform to CAN/CSA-B365,
Installation Code for Solid Fuel Burning Appliances and
Equipment.
NOTE: Do not vent your Dutchwest stove into a factory-
built (zero-clearance) fireplace. These appliances and
their chimneys are specifically designed as a unit for
use as fireplaces. It may void the listing or be hazard-
ous to adapt them for any other use.
Floor Protection
A tremendous amount of heat radiates from the bottom
plate of your Dutchwest stove. The floor area directly
under and around the stove will require protection from
radiant heat as well as from stray sparks or embers that
may escape the firebox.
Heat protection is provided through the use of a CFM
Corporation Bottom Heat Shield. Spark and ember
protection must be provided by a floor protector con-
structed with noncombustible material as specified.
Most installations will require that the bottom heat
shield be attached. Only when the stove is placed on a
completely noncombustible surface such as unpainted
concrete over earth may it 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 inches from the
front and left (loading door) side of the stove, and at
least 6 inches from the right side and rear. (Fig. 12)
Refer to Figure 12 for minimum noncombustible floor
protection dimensions for each stove model.
In Canada: a noncombustible floor protector is required
under the heater also. The floor protector must extend
18 inches (457mm) from the front and left (loading
door) side of the stove, and at least 8 inches (203mm)
from the right side and rear. (Fig. 12)

ments on all four sides of the stove.

Fig. 13 Combustible supporting timbers (A) may lie beneath
fireplace hearths; such situations require additional floor
protection.
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.
Fireplace Installations
You may install your Dutchwest Convection Heater in
an existing fireplace as a fireplace insert with no legs,*
or with the standard legs attached.
