Drafting
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 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.
