result of catalytic combustor that is coated with precious
metals to cause smoke to burn at temperatures lower than
normal.
Sequoia Control Settings for Coal Fires
(The primary air and combustor air controls always
remain closed. Primary air is closed a the 5:00 position,
while the combustor air is closed when rotated fully
clockwise.)
Burn Rate Coal-Only Air
Low 1/2 turn
Medium 1
¹⁄₂
turns
High Fully open
If your stove is equipped with an optional blower, it is
important to follow these guidelines as well for best
results:
At low-to-medium heat outputs, (a control setting of
6:00 to 7:00) the optional convection blower switch
should be set on the “low” position, never on “high”.
At higher heat outputs, (8:00 or more) the blower can
be set on high if desired.
NOTE: The coal-only air control must always be
closed during a wood fire. Likewise, the primary
and combustor air controls must be close when
burning coal.
DO NOT OPERATE THE STOVE WITH THE ASH
DOOR OPEN. THIS CAN CAUSE EXTREME
OVERFIRING OF THE STOVE, WHICH IS DANGER-
OUS.
The stove’s paint and cement will emit a slight odor
during the first few fires. We suggest that you
provide extra ventilation near the stove by partially
opening a door or window when the odor is
present.

How to Build a Wood Fire
and Keep it Going
Make sure your stove is set up correctly for burning
wood.
A Sequoia leaves the factory with the catalytic
combustor installed.
In the United States it is against the law to operate this
wood heater in a manner inconsistent with the operat-
ing instructions in this manual, or if the catalytic com-
bustor is deactivated or removed.
The grate covers are also installed. These are neces-
sary for wood burning and should be left in place.
High-Efficiency Wood Burning
with Catalytic Combustion
Smoke from a wood fire is really escaping energy that
has not been burned to produce the heat. Combustion
temperatures of 1100
°
F (595
°
C) are required to burn
the smoke, and a level this high seldom is present in a
fire set to burn several hours. As a result, long fires in
conventional stoves lose a great deal of potential heat
up the chimney as smoke.
A catalytic combustor captures this heat by lowering the
temperature at which smoke will burn. This makes high
efficiency possible even with long, low level fires.
Catalytic combustion is activated with two adjustments:
by closing the stove damper, thereby exposing the
smoke to the combustor, and by opening the combustor
air control. The combustor needs extra air during
medium and high burns, and the Sequoia’s combustor
air control must be fully open to supply it. During low
burns, the combustor air control should be open only a
1/2 turn.
Closing the stove damper also reduces the draft, so to
avoid putting out the fire or deactivating the combustor,
close the damper only when a fire is well established.
When starting a fire, wait until the fire is well estab-
lished and there is an ember bed of at least two inches
before closing the stove damper.
