This appliance is not designed to be operated in a negative pressure.
In very airtight homes with large kitchen exhaust fans, furnace cold air
returns, fresh air exchange systems and any other air system in close
proximity to the heating appliance may create a 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 here.
Ventilation Requirements - Provide adequate air for combustion. The
fresh air requirements of this appliance must be met within the space
where it will be installed. Ventilation is essential when using a Solid-Fuel-
Burning heater. In well insulated and weather tight homes, it may be
difficult to establish a good draft up the chimney (caused by a shortage
of air in the home). The lack of air is caused by many common household
appliances which exhaust air from the home (such as a furnace, heat
pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other
fuel burning appliances). Also, the combustion process of this heater
uses oxygen from inside the dwelling. If the available fresh air delivery
in the dwelling is insufficient to support the demands of these appliances,
problems can result (i.e. excessive negative pressure can develop in the
dwelling which will affect the rate at which this appliance can draft thus
resulting in performance problems. To correct this problem it may help
to open a window (preferably on the windward side of the house) or
install an optional outside air kit.
This unit is designed and engineered to burn, dry, well-seasoned 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.
Do Not store fuel within space heater installation clearances or within
the space required for refueling and ash removal.
CREOSOTE FORMATION AND NEED FOR REMOVAL
NEGATIVE PRESSURE WARNING
DISPOSAL OF ASHES
FUEL
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 and moved
outdoors immediately. Other waste shall not be placed in this container.
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.
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
monthly during the heating season to determine if a creosote buildup has
occurred. If creosote has accumulated (1/8” [3 mm] or more), it should
be removed to reduce the risk of a chimney fire.
If your stove has plated accessories, be sure to clean it with a household
type 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 “Burn-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.
Your new appliance is painted with a 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 a high temperature stove paint (cat. no. H8159), available from all
Lennox Hearth Products dealers.
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 mois-
ture, 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).
BURN-IN PERIOD
PAINT CURING
Establish a routine for the fuel, wood burner and firing technique.
Check daily for creosote build-up until experience shows how often
you need to clean to be safe. Be aware that the hotter the fire the
less creosote is deposited, and weekly cleaning may be necessary
in mild weather even though monthly cleaning may be enough in
the coldest months. Contact your local municipal or provincial fire
authority for information on how to handle a chimney fire. Have a
clearly understood plan to handle a chimney fire.
