Dutchwest Non-Catalytic Convection Heater
30002278
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 by the CFM Corporation
Bottom Heat Shield. Spark, ember and thermal protec-
tion must be provided by a floor protector constructed
with noncombustible material as specified.
In the US and Canada most installations will require
that the bottom heat shield must be attached. Only
when the stove is placed on a completely noncombusti-
ble 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 an
approved 5/8” (16mm) noncombustible hearth pad with
K = 0.84 BTU/in ft

an R-value of at least 0.744. (Refer to “How to Deter-
mine if Alternate Floor Protection Materials are Accept-
able” section)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)
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 8” (203mm) from the right side
and rear. (Fig. 12)

How to Determine if Alternate Floor Protection Ma-

All floor protection must be noncombustible (i.e. met-
als, brick, stone, mineral fiber boards, etc.). Any organic
materials (i.e. plastics, wood paper products, etc.) are
combustible and must not be used. The floor protection
specified includes some form of thermal designation
such as R-value (thermal resistance) or k-factor (ther-
mal conductivity).
