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 fireplace insert
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.
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 fireplace insert 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.
Lennox Hearth Products accepts no liability for damages resulting from
negative pressures described above.
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).
This unit is designed and engineered to burn, dry, well-seasoned wood
only.
Ashes should be scooped out of a cool fireplace insert 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 fireplace insert.
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, it should be removed to reduce the risk of
a chimney fire.

If your fireplace insert 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 fireplace insert
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 fireplace
insert through a regimen of three burns. The first two should last for 20
minutes each at 250 degrees (the fireplace insert 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 fireplace insert
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 OR INSERT. 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 fireplace insert 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 fireplace insert and may make it dif-
ficult to start. After you have broken in the paint on the fireplace insert
it will be necessary to build hot fires to thoroughly remove the moisture
from the appliance. Running the fireplace insert 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 fireplace insert
top or chimney. Temperatures on the connector pipe should run in the
250-600 degree range. (DO NOT OVERFIRE THE STOVE OR INSERT
DURING THIS PROCESS. IF THE STOVE OR CHIMNEY BECOMES
RED, REDUCE THE AMOUNT OF AIR ENTERING THE STOVE OR
INSERT IMMEDIATELY).
