TesTing informaTion
This manual describes the installation and operation of the
Canyon™ ST310 non-catalytic wood heaters. These heaters
meet the U.S. Environmental Protection Agency’s emissions
limits for wood heaters sold on or after July 1, 1990. This
heater has been developed, tested and constructed in accordance with the requirements of UL 1482, ULC S627-00
and HUD standards and is listed by OMNI Test Laboratories,
Beaverton, OR. It has been approved for residential, mobile
home, and alcove installations.
general safeTy PrecauTions
1. When this room heater is not properly installed, a
house fire may result. To reduce the risk of fire, follow
the installation instructions. Contact local building
or fire officials about restrictions and installation
inspection requirements in your area.
8. Do not allow children to play near the stove without
close supervision. Do not touch the stove while it
is burning. Use extreme caution while the unit is
in use. Surface temperatures become dangerously
hot and can cause serious burns.
9. Do not allow anyone to operate the stove who is
not familiar with the operating instructions.
10. Attempts to achieve heat output rates that exceed
stove design specifications can result in permanent
damage to the stove. Never leave your stove unattended on high burn rates. This may cause overfiring.
Overfiring the stove may cause a house fire. If the
stove glows, you are overfiring.
11. Use smoke detectors near your stove as well as in
sleeping areas. Keep a water hose or hand-operated
fire extinguisher close for safety.
2. Wear gloves during installation to avoid injury from
sharp edges on the stove and/or its parts.
3. This unit is designed and engineered to burn only
dry, well-seasoned wood. Burning wet wood will
greatly reduce your stoves efficiency, produce excessive amounts of smoke, and can cause dangerous
chimney fires due to creosote build-up.
4. Before opening the door, the
draft control must be
fully open to avoid possible combustion flash (igni-
tion of hot volatile gases as the door is opened).
5. Do not use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids
to start or “freshen up” a fire in this stove. Keep all
flammable liquids and combustible materials 36”
from any point of the stove when it is in use.
6. While burning, fuel utilizes oxygen from the air in the
room. Be sure to allow an adequate amount of fresh
air into the room where the stove is burning.
7. The outside surface of the stove will be hot while
burning properly and can set items like clothing
and curtains on fire. Keep furnishings and other
combustible materials away from the stove. Using
the heat from the stove to dry wet clothing can be
hazardous if clothes are placed too near the surface
of the stove.
12. Inspect your chimney at least once a month during
the burning season to check for soot and creosote
accumulations. Any accumulations over 1/4” thick
should be removed by a professional chimney
sweep. Do not attempt to burn out heavy creosote
accumulations with a hot fire. If large accumulations
are occurring, review your burning procedures.
13. If a creosote fire should develop, the fire department
should be called immediately, and then attempts
should be made to control the fire until assistance
arrives. If a “runaway” fire should develop causing
over-heating of the stove, the door and draft regulators should be closed immediately. The fire should
die down once deprived of oxygen. After a severe
chimney fire, the complete chimney system should
be checked before further use.
14. Do not operate with a grate or with an elevated
fire. Always build the fire on the surface of the
firebrick.
15. Please read this entire manual before you install
and use your new room heater. Failure to follow
instructions may result in property damage, bodily
injury, or even death.

DrafTing
negaTive Pressure Warning
Your wood stove is dependent upon a properly functioning
chimney for optimum performance. It is a high efficiency
appliance that loses much less heat up the chimney than
older appliances and fireplaces. For this reason it is important
to match the stove to the chimney. The chimney has two
functions: 1) It draws combustion air into the appliance
(without air, no fuel will burn) and 2) It exhausts combustion
by-products. Your new Country™ Collection stove is what is
known as a “natural draft” appliance. The appliance depends
solely on the natural draft of the chimney system to draw
combustion air into the unit. Draft is the force that moves
air from the appliance up into the chimney. The amount of
draft in your chimney depends on the length of the chimney,
local geography, nearby obstructions, and other factors. Too
much draft may cause excessive temperatures in the appliance. Slow or inadequate draft equals poor combustion and
possible smoking problems. The two main culprits of poor
chimney draft are: 1) A chimney too large for your appliance and 2) A chimney with not enough height to produce
adequate draft for your particular stove model. Your Lennox
Hearth Products dealer will be able to advise you on matching
a proper system for your new stove. Inadequate draft will
cause the appliance to leak smoke into the room through
the stove and the chimney connector joints. An uncontrollable burn or a glowing red stove or chimney part indicates
excessive draft. Also see Troubleshooting on page 18.
This appliance is not designed to be operated in a negative
pressure. Very airtight homes with large kitchen exhaust
fans, or homes with furnace cold air returns located in close
proximity to the wood stove or fireplace insert may create
negative pressure in the same room as the heating appliance. This can create dangerous back drafting of the stove
and chimney joints, drawing combustion by-products into
the home. Be sure your home has adequate makeup air to
eliminate negative pressures caused by the above-mentioned
sources. Outside air connected to the appliance probably
will not resolve such a problem as the stove or fireplace
insert is not the source of negative pressure. Lennox Hearth
Products accepts no liability for damages resulting from
negative pressures described above.
creosoTe
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 flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited, this creosote makes an extremely hot fire.
The chimney and chimney connector should be inspected
at least once every two months during the heating season
to determine if a creosote build-up has occurred. If creosote
has accumulated, it should be removed to reduce the risk
of a chimney fire.

ash DisPosal
Ashes should be scooped out of a cool stove with a small
metal shovel. 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 on the ground, well
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 the cinders have thoroughly cooled. Ashes can ignite
up to 72 hours after removal from the stove.
fuel
This unit is designed and engineered to burn, dry, wellseasoned wood only. Dry, seasoned wood is that which
has been cut, split, and allowed to dry under a covered area
where air is free to flow and circulate under and around the
wood (not under a tarp or plastic). Make sure wood is not
stacked directly on the ground, it may absorb moisture from
the ground. It should be allowed to dry in these conditions
for a minimum of six months, preferably one year or more.
IT MUST BE UNDERSTOOD THAT WOOD CANNOT BE
LEFT IN ANY KIND OF WET OR DAMP AREA OR IT WILL
NEVER BECOME COMPLETELY SEASONED. Your stove will
not operate at the level that it is meant to unless you use
seasoned, dry wood. Do not burn driftwood or wood that
has been in salt water, doing so will void your warranty. Do
not burn treated wood, coal, garbage, cardboard, solvents,
or colored paper. Burning treated wood, garbage, solvents,
or colored paper may result in the release of toxic fumes.
This type of burning will also void your warranty.
Break-in PerioD
Please be patient with the heat output of your stove for the
first few weeks. The steel will go through a curing process that
eliminates moisture, which is deep in the steel and firebrick.
This moisture will reduce initial heat output of your stove
and may make it difficult to start. After you have broken in
the paint on the stove it will be necessary to build hot fires
to thoroughly remove the moisture from the appliance. Running the stove with the draft fully open for 1 to 1-1/2 hours
after starting and adding generous amounts of fuel during
the first week or two should complete the curing process.
We recommend the use of a thermometer attached to the
stovetop or chimney. Temperatures on the connector pipe
should run in the 250-600 degree range. (DO NOT OVERFIRE
THE STOVE DURING THIS PROCESS. IF THE STOVE OR
CHIMNEY BECOMES RED, REDUCE THE AMOUNT OF AIR
ENTERING THE STOVE IMMEDIATELY).
PainT curing
Your new Canyon™ ST310 is painted with Forest High
Temperature Paint that cures during the first few firings.
We recommend that you put your stove through a regimen
of three burns. The first two should last for 20 minutes
each at 250 degrees (the stove should be allowed to cool
completely between each burn). The third should be a burn
of at least 450 degrees F. for 45-60 minutes. The paint will
become soft, gummy, and emit non-toxic smoke during
these burns. After the stove cools down for the third time,
the paint will harden. DO NOT BUILD A LARGE ROARING
FIRE UNTIL THIS CURING EFFECT IS COMPLETE OR YOU
MAY DAMAGE THE FINISH OF YOUR STOVE. Spray can
touch-ups should be done only with Forest brand paint,
available from all Lennox Hearth Products dealers.
If your stove has a Gold or Nickel-Plated Door, be sure
to clean it with Windex brand glass cleaner and a very
soft cloth to remove any fingerprints and residues prior
to the first fire and before any fire if the gold has been
handled or soiled. Do not close the door tightly during
the “Break-in Period.” Also, open the door frequently
(every 5-10 minutes) to keep the gasket from adhering to
the curing paint. Ventilate the house well during these first
firings as the paint gives off carbon dioxide and unpleasant odors. It is recommended that persons sensitive to an
imbalance in the indoor air quality avoid the stove during
the curing process.
