Floor Protection
A tremendous amount of heat radiates from the bot-
tom plate of your Sequoia 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
Dutchwest Bottom Heat Shield. Spark and ember pro-
tection must be provided by a floor protector construct-
ed 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

Wall Pass-Throughs
Whenever possible, design your installation so the con-
nector does not pass through a combustible wall. If you
must use a wall pass-through in your installation, check
with your building inspector before you begin and con-
struct it in accordance with local building codes. Also
check with the chimney connector manufacturer for any
specific requirements.
Accessories are available for use as wall pass-
throughs. If using one of these, make sure it has been
tested and listed for use as a wall pass-through.
In the United States, the national Fire Protection As-
sociation (NFPA) has established guidelines for passing
chimney connectors through combustible walls. Many
building code inspectors follow these guidelines when
approving installations.
Figure 10 shows one NFPA-recommended method. All
combustible material in the wall is cut away a sufficient
distance from the single-wall connector to provide the
required 12” (305mm) clearance for the connector. Any
material used to close up the opening must be noncom-
bustible.
In Canada, the Canadian Standards Association has
established different guidelines. Figure 11 shows one
method, in which all combustible material in the wall is
cut away to provide the required 18” (457mm) clear-
ance for the connector. The resulting space must re-
main empty. 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 noncombustible
spacers at least 1” (25mm) clear of the wall. Your local
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 Sequoia 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 hazardous to
adapt them to any other use.
DO NOT CONNECT THE HEATER TO ANY AIR DIS-
TRIBUTION DUCT OR SYSTEM.
Three other methods are also approved by the NFPA.
These are:
•
Using a section of double-wall chimney with a 9”
clearance to combustibles.
•
Placing a chimney connector pipe inside a ventilated
thimble, which is then separated from combustibles
by 6” of fiberglass insulating material.
•
Placing a chimney connector pipe inside a section
of 8” diameter, solid-insulated, factory-built chimney,
with 2” of air space between the chimney section
and combustibles.
