Drafting

Your wood stove is dependent upon a properly functioning

chimney for optimum per formance. 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 Prod-

ucts 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 16.

negative Pressure Warning

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 appli-

ance. 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 accumu-

lates 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 buildup has

occurred. If creosote has accumulated, it should be removed

to reduce the risk of a chimney ﬁre.
