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). BURN-IN PERIODPAINT CURING
