OVERALL DIMENSIONS ACHIEVING PROPER DRAFT

Draft is the force which moves air from the appliance up
through the chimney. The amount of draft in your chimney
depends on the length o f the chimney, local geography,
nearby obstructions and other factors. Too much draft may
cause excessive temperatures in the appliance. An
uncontrollable burn or a glowing red stove part or chimney
connector indicates excessive draft. Inadequate draft may
cause back puffing into the room and plugging of the
chimney. Symptoms of inadequate draft include leaking of
smoke into the room through the appliance and/or chimney
connector joints. A minimum draft of .06wc is required for
proper operation.

Your Sierra Stove must not be connected to a chimney
serving another appliance. Multiple appliances on a single
flue may cause flue gases to be drawn into the house
through an unused opening, or in the form of poor draft and
rapid creosote accumulation.

The Sierra Stove will not sm oke if installed according to
manufacturer's specifications and with a listed chim ney.

A scheduled plan for cleaning the chimney must be
observed. A build-up of resins from wet or green wood can
cause a flue fire (see Maintenance Section).

Special methods are required when passing chimney through
a wall or ceiling. See Pipe Instructions Manual and/or local
building codes.

Do Not Over-fire this Heater: Attempts to achieve heat
output rates that exceed heater design specifications can
result in perm anent damage to the heater. A glowing stove

or connector pipe is hazardous!

HEARTH PROTECTION

Floor protection and/or hearth extension is required for the
Sierra Stove. All floor protection materials must be non­combustible (i.e., metals, 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 protector specified may include some form of thermal
designation such as an R-value (thermal resistance), k-factor
(therm al conductivity), or C-factor (therm al conductance).
The easiest means of determining a proposed alternate floor
protecto r that meets the requirem ents liste d in this m anual is
to follow this procedure:

1) Convert specification to R-value:

i) R-value given - no conversion needed.

ii) k-factor is given with a required thickness (T) in

inches: R 1/k x t

iii) C-factor is given: R - 1/C

2) Determine t R-value of the proposed alternate

floor protector.

i) Use the formula in step (1) to convert values not

expressed as "R".

ii) For multiple layers, add R-values of each layer

to determine overall R-value.

3) If the overall R-value of the system is greater

than the R-value of the specified floor protector,
the alternate is acceptable.

Example: The specified floor protector should be 3/4 inch
thick m aterial with a k-factor of .84. The proposed alternate
is 4" brick with a C-factor of 1.25 over 1/8" m ineral board with
a k-factor of .29.

Step (a): Use formula above to convert specification to

R-value. R=1/k x T-1/.84 x.75=.893

Step (b): Calculate R of proposed system. 4" brick of

C-1.25, therefore Rbrick=1/C -1/1.25 -.80

1/8" mineral board of k-.29, therefore Rmin.bd.-

1/.29x.125-.431

Total R-Rbrick-Rmineral board-.8+.431=1.231

Step (c): Compare proposed system R of 1.231 to

specified R of .893. Since proposed system R is greater

than required, the system is acceptable.

SPECIAL FEATURES

Your Sierra Stove is
equipped with a special
design to meet clean air
standards. Please follow
the starting instructions
carefully to ensure you are
using your woodstove in the
clean, efficient manner for
which it was designed.

A special drafting pattern is employed in your Sierra Stove
which provides an "air-wash" across the inside face of the
glass thereby reducing the frequency with which the glass
require s cleaning. Proper usage of these controls is
discussed in the Starting Instructions section.

Your Sierra Stove may be configured as a free-standing
heater or a fireplace insert. The free-standing unit hasl bases
that include pedestal and standard iron legs. All units are

approved for mobile home installations with outside air.

BREAK-IN PERIOD

Your Sierra Stove has been painted with the highest quality
silicone stove paint and has special break-in procedures to
for proper curing.

* Ventilate the house. It takes heat to activate the silicone
resin and this process gives off carbon dioxide smoke.

* Don't touch the surface. It will be soft and gummy during
the curing phase. Once cured, it will not be soft again.

* Most stoves cure with three burns. The first two should be
250EF for 20 minutes, or about half of a normal fire. Let the
stove cool down between burns. The last fire should be
500EF to 700EF for at least 45 minutes. The point being,
cure slowly without a hot fire.

* Curing can usually be observed by the effect of the paint
turning flat as the heat radiates out from the hotter parts of
the stove.

OPERATING AND SAFETY TIPS

Always exercise caution when operating your stove and
follow these important safety tips.

Figure 1

1. Never use gasoline, 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.

2. A glowing red stove is dangerous! Never fire your stove
to over 1000EF surface temperature. Never stoke up the fire
so hot that it changes color of the surface of the stove. Cool
the fire quickly by closing the stove door and bottom air
control. The fire should die down once deprived of oxygen. If
the fire doesn't die, call the fire department for assistance.

CAUTION: In airtight s toves after closing the bottom air
control, volatile gases are still given off by the wood
smoldering in the firebox. A sudden burst of oxygen caused
by opening the draft control or door while stove is smoldering
will ignite the volatile gases and may result in a sudden burst
of flam e with a muffled report. This may sound very similar to
a gas furnace igniting. Always increase the air intake
gradually. D o n ot open it all the way until you see flame in
your firebox. Always open bottom air intake before you open
the door.

3. Never hang clothes near the stove to dry as they may
catch fire. Keep furniture, drapes, wood supply and any other
combustibles 3 feet away from your woodstove.

4. Never burn garbage in your woodstove. By garbage we
mean: plastics, aluminum wrappers, slick paper magazines
or styrofoam of any kind. Garbage fouls your chimney and
the air.

5. Use caution when loading fuel into stove after it is already
burning vigorously. Avoid resting fuel against the glass as this
will cause dirty spots.

6. Burn dry wood only. Do not use coal as fuel.

7. Educate your children to the dangers associated with fire,

and the presence of the hot appliance. Child guards are
available through your dealer. Never allow a child to operate
your woodstove.

8. Combustion Air: Fire consumes oxygen, therefore a fresh
outside air source must be provided in order to maintain a
healthy atm osphere within the house. O pen a window slightly
when operating the Sierra Stove.

9. Disposal of Ashes: Ashes should be placed in a metal
container with a tight-fitting lid. The closed container of ashes
should be placed on a non-combustible floor or the ground,
away from all
combustible materials,
pending final disposal. If
the ashes are disposed
of by burial in soil or
otherwise locally
dispersed, they should
be retained in the closed
container until all cinders
have thoroughly cooled.

10. Flue Fires: Always
a potentially dangerous
situation, a flue fire can
usually be controlled by
depriving the fire of
oxygen. Accomplish this
by closing the stove door
tightly and closing draft regulator snugly. The Fire
Department should always be called to avoid letting the
situation get out of control. Flue fires can be avoided by
maintaining your chimney (See Creosote and M aintenance).

11. Smoke Detectors are a very good investment for the
protection of your family and home.

12. Build fire directly on the fire bricks of the stove. Do not
use grates or andirons to elevate wood.
