Clearance To Combustibles
Your appliance was designed to
burn wood only; no other materials
should be burned. Waste and other
ammable materials should not be
burned in your appliance. Any type of
wood may be used in your appliance,
but specic varieties have better
energy yields than others. Please
consult the following table in order to
make the best possible choice.
It is EXTREMELY IMPORTANT that you
use DRY WOOD only in your wood
appliance. The wood should have
dried for 9 to 15 months, such that the
humidity content (in weight) is reduced
below 20% of the weight of the log. It
is very important to keep in mind that
even if the wood has been cut for one, two, or even more years, it is not necessarily dry if it has been stored in
poor conditions. Under extreme conditions it may rot, instead of drying. This point cannot be over stressed; the
vast majority of the problems related to the operation of a wood appliance is caused by the fact that the wood
used was too damp or has dried in poor conditions. These problems can be:
- Ignition problems
- Creosote build-up causing chimney res
- Low energy yield
- Blackened windows
- Incomplete log combustion
Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be
stored directly on the ground. Air should circulate through the cord. A 24” to 48” air space should be left between
each row of logs, which should be placed in the sunniest location possible. The upper layer of wood should be
protected from the elements but not the sides.
FLOOR PROTECTION
This appliance must only be installed on the required brick kit.
CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same
diameter as the appliance outlet (10”). If this is not the case, we
recommend you contact your dealer in order to insure there will be
no problem with the draft.
The stove pipe must be made of aluminized or cold roll steel with a
minimum thickness of 0.021” or 0.53 mm. It is strictly forbidden to use
galvanized steel.
Your smoke pipe should be assembled in such a way that the male
section (crimped end) of the pipe faces down. Attach each of the
sections to one another with three equidistant metal screws. Seal
with furnace cement.
The pipe must be short and straight.
To insure a good draft, the total length of the coupling pipe should never exceed 8’ to 10’ (2.4m to 3.04 m).
Installation of a “barometric draft stabilizer” (replace register) on a smoke exhaust system is prohibited.
Furthermore, installation of a draft damper is not recommended. Indeed, with a controlled combustion wood
appliance, the draft is regulated upon intake of the combustion air in the appliance and not at the exhaust.

TESTING YOUR WOOD
When the appliance is thoroughly warmed, place one piece of split wood (about ve inches in diameter)
perpendicular to the door on the bed of red embers.
Keep the air control full open by sliding it right and close the door. If ignition of the piece is accomplished within
90 seconds from the time if was placed in the appliance, your wood is correctly dried. If ignition takes longer,
your wood is damp.
If your wood hisses and water or vapor escapes at the ends of the piece, your wood is soaked or freshly cut. Do
not use this wood in your appliance. Large amounts of creosote could be deposited in your chimney, creating
potential conditions for a chimney re.
THE FIRST FIRES
The fresh paint on your appliance needs to be cured to preserve its quality. Once the fuel charge is properly
ignited, only burn small res in your appliance for the rst four hours of operation. Never open the air control more
than necessary to achieve a medium burn rate.
Make sure that there’s enough air circulation while curing the appliance. The odors may be smelled during the
rst 3 or 4 res. During curing people and animals with lung problems should take caution.
IGNITION
Place several crumpled sheets of paper in the center of the combustion chamber. Place 8 to 10 pieces of small
dry kindling wood over the paper in the form of a tent. No chemical product should be used to light the re.
Before igniting the paper and kindling wood, it is recommended that you warm up the chimney. Twist together
a few sheets of newspaper into a torch. Light up this paper torch and hold it as close as possible to the back of
the combustion chamber to warm up the chimney. Once the updraft movement is initiated, you are ready to
ignite the appliance by lighting the paper and kindling wood inside the combustion chamber.
RELOADING
Once you have obtained a good bed of embers, you should reload the unit. Bring the red embers to the front
of the appliance and reload the unit. For optimal operation of your wood appliance, we recommend you to
operate it with a wood load approximately equivalent to the height of re bricks. Creosote - Formation and
Need for Removal - When wood is burned slowly, it produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney ue of a slow-
burning re. As a result, creosote residue accumulates on the ue lining. When ignited, this creosote makes an
extremely hot re. The chimney connector and chimney should be inspected at least once every two months
during the season to determine if a creosote build-up has occurred. If creosote has accumulated (3mm or more),
it should be removed to reduce the risk of a chimney re.
TO PREVENT CREOSOTE BUILD UP
• Always burn dry wood. This allows clean burns and higher chimney temperatures, therefore, less creosote
deposit.
• Always check for creosote deposit once every two months and have your chimney cleaned at least once a
year.
If a chimney or creosote re occurs, close all dampers immediately. Wait for the re to go out and the appliance
to cool. Then, inspect the chimney for damage. If no damage results, perform a chimney cleaning to ensure
there is no more creosote deposits remaining in the chimney.
ASH DISPOSAL
Ashes should be removed from the appliance every few days or when ashes get to 2 to 3 inches deep. Always
empty the appliance when it is cold, such as in the morning. Ashes should be placed in a metal container with
a tight tting lid. The closed container of ashes should be placed on a non combustible oor or on the ground,
well away from all combustible materials, pending nal 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. Other waste shall not be placed in this container.
Warnings: Never overre your appliance. If any part of the appliance starts to glow red, over ring is happening.
Readjust the air intake control at a lower setting. The installation of a log cradle or grates is not recommended
in your wood appliance. Build re directly on rebrick. Never put wood above the rebrick lining of the rebox.
CAUTIONS:
• Ashes could contain hot embers even after two days without operating the appliance.
• The ash pan can become very hot. Wear gloves to prevent injury.
FUEL STORAGE
Wood can be dried sufciently for burning within a few weeks if protected form rain in a low humidity area. It
is far better to cut wood and allow it to dry for a year. In all cases, the wood should be stacked so that both
ends of the sticks are exposed to the air and protected from rain. The drier the wood, the more usable heat
produced by the re and less likely rapid accumulation of soot and creosote within the chimney is to occur. See
the section of this manual concerning chimney maintenance for information concerning the hazards of soot a
creosote accumulation. Small quantities of wood required for re tending must be kept at least 30 inches from
the replace.
CHIMNEY MAINTENANCE
Creosote, Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively
cool chimney ue of a slow-burning re. As a result, creosote residue accumulates on the ue lining. When
ignited, this creosote makes an extremely hot re.
The chimney should be inspected at least twice a year during the heating season to determine if a creosote
buildup has occurred.
If creosote has accumulated it should be removed to reduce the risk of a chimney re.
The chimney cap can be removed for inspection, maintenance and cleaning by removing three screws from
the support legs and lifting upward.
When the replace is rst in use, inspect the chimney frequently and clean the chimney any time an accumulation
is observed on the ue walls. The frequency of these inspections can be increased or reduced appropriately
after a pattern of accumulation has been established. Please note, however, that changes in the outside
environmental conditions such as temperature and humidity or changes in the operation of the replace can
lead to rapid buildup of soot and/or creosote.
To clean the chimney, obtain the services of a qualied and reputable chimney sweep, or remove the
accumulation with brushes on wooden or berglass poles. Do not use metal pipes, chains, wires, etc., to clean
the chimney because such items can scratch the surface of the stainless steel ue which can shorten the life of
the ue and provide a rough surface for soot particles to attach to.
Be sure to cover nearby furnishing and arrange some method of catching soot and creosote particles that may
fall during the chimney cleaning process.
In addition to checking and cleaning the chimney on a regular basis, be sure to inspect the chimney before
starting a re at the beginning of each heating season. Make sure the chimney is clear from any accumulation
of soot, creosote or any other debris, and that all joints are intact.
United States Stove Co. does not recommend chemical cleaners because some may contain elements that
corrode the metal parts of the chimney or replace.
FIREPLACE MAINTENANCE
At the end of each heating season or when the replace will not be in use for an extended time, the ashes should
be removed and the hearth area should be swept as clean as is practical. The slow absorption of moisture into
the ashes over a long period of time could cause a condition which would be corrosive to the metal replace
parts.
As you use the replace, expansion and contraction will cause minor cracking of the hearth, back, and side
refractory materials. This is normal and unavoidable. If the cracks become large enough or parts dislodge and
metal behind the refractory is exposed, the refractory panels should be replaced with new panels that can be
obtained from you replace dealer.
