Never kindle a fire with colored paper or paper that has
colored ink or a glossy surface, and never burn treated
wood, garbage, solvents, or trash. All of these may
poison the catalyst and prevent it from operating
properly. Never burn cardboard or loose paper except
for kindling purposes. This can cause smoke to spill into
the room and effect the combustor operation. Coal
smoke can also poison the catalyst so that it will not
operate properly.
In general, the temperature in the stove and the gases
entering the combustor must be raised to approximately
800
°
F (430
°
C) to ensure that catalytic activity is initi-
ated. During the start-up of a cold stove, a medium-to
high-firing rate must be maintained for about twenty
minutes. This ensures that the stove, catalyst and fuel
are all stabilized at the proper operating temperatures.
Even though it is possible to have gas temperatures
reach several hundred degrees within two to three
minutes after a fire is started, the combustor may stop
working or the fire may go out if the fire is allowed to die
down immediately. Once the combustor starts working,
heat generated by burning the smoke will keep it
working.
The best operating range for the combustor is a reading
of 1000-1400
°
F (540-760
°
C) on a probe thermometer.
Temperatures over 1700
°
F (925
°
C) may damage the
combustor.
To determine whether the combustor is operating,
check the probe thermometer in the top of the stove. If
it reads 800
°
(430
°
C) or higher, it is likely that the
combustor is operating. If temperatures are lower than
this, increase the intensity of the fire either by adding
fuel or by increasing the amount of primary air.
Another way to tell if the combustor is working is to
observe the amount of smoke leaving the chimney
when the damper is activated and when it is not. This
procedure is described on Page 25.
Conditioning Your Stove
Cast iron is extremely strong, but it can be broken with
a sharp blow from a hammer or from the thermal shock
of rapid and extreme temperature changes.
The cast plates expand and contract with changes in
temperature. When you first begin using your Sequoia,
minimize thermal stress by allowing the plates to adjust
gradually during three or four initial break-in fires
following Steps 1-3 below.
Starting and Maintaining a Wood Fire
Wood may be loaded into the Sequoia from either the
front or the side. Loading from the front is useful for
kindling a new fire or adding an occasional log, but we
recommend side loading as the most convenient way of
regularly adding several logs at a time.
When burning wood, your Sequoia may be operated
with the front doors open, for fireplace-style viewing, as
well as closed. The stove damper must be open and
the
firescreen must be in place whenever the door is
open for fire viewing.
WARNING: For safety and greatest efficiency,
operate your stove only with all doors fully closed.
The test standard when the stove is operated in this
mode is UL1482.
Your stove may be operated as a fireplace with the
doors opened or removed only when equipped with
an 8” (200mm) flue collar and only with the optional
spark screen placed correctly in the opening to
protect against the possibility of sparks and em-
bers leaving the stove. The test standard for your
stove when it is operated in this mode is UL737.
Use only the Sequoia spark screen, Part Number
0135, with your Sequoia. Sequoia spark screens are
available from your Dutchwest authorized dealer.
1. Open the stove damper, and open the primary air
control fully. Open the combustor air control two
turns. The coal only air control must always be
closed during wood burning.
2. Place crumpled newspaper in the stove. Do NOT
use glossy advertisements or colored paper, as they
can poison the catalyst. Place six or eight pieces of
dry kindling split to a finger-width size on the paper,
and on the kindling lay two or three larger sticks of
split dry wood approximately 1-2” (25-50mm).
DO NOT USE CHEMICALS OR FLUIDS TO START
THE FIRE. DO NOT BURN GARBAGE OR FLAM-
MABLE FLUIDS SUCH AS GASOLINE, NAPTHA OR
ENGINE OIL. Also, never use gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar liquids to
start or “freshen up” a fire in this heater. Keep all such
liquids well away from the heater while it is in use.
3. Light the newspaper and close the door. Within 10-
15 minutes the fire should be well established and
you may gradually build up the fire by adding a few
3-5” (80-120mm) diameter splits. If this is one of the
first few “break-in” fires, let the fire burn brightly, and
then let it die out.
If the break-in procedure has been completed,
continue building the fire until you have a live ember
bed about 2” (50mm) thick.
You will soon find out that this stove is HOT WHILE IN
OPERATION! KEEP CHILDREN, CLOTHING AND
FURNITURE AWAY. CONTACT MAY CAUSE SKIN
BURNS.
NOTE: Some chimneys, especially oversized or
exterior chimneys, need to “primed”, or warmed up,
before they will draw sufficiently to start a fire. To
