Most are correctable and generally require only
a minor adjustment of the stove, installation, or
operating technique. In cases where weather
conditions dramatically

temporary and solve themselves once the
weather changes.
One common cause of poor performance is an
oversized chimney flue.
flues result in decreased pressure, which
prevents the smoke from rising out the
chimney. Oversized flues are also more difficult
to heat effectively, especially when burning a
high efficiency stove. Cool flue temperatures
inhibit the establishment of a strong draft (and
encourage the accumulation of creosote). The
lack of a strong draft will cause the fire to die
down and may even force the smoke to pour
into the room.
If your chimney is the proper size and a strong
draft is not easily established, there is the
possibility of the chimney being too cold.
Again, hot chimneys promote a stronger draft.
Other draft guidelines are as follows:
AN "AIRTIGHT" HOUSE:
super-insulated or especially well sealed, the
(infiltration) air supply to the interior of the
house may be inadequate. This phenomenon
of air starvation within the building can be
exacerbated if exhaust fans, such as clothes
dryers, bathroom fans or cook-stove exhaust
fans, are in operation within the home.

obstructions, when located in proximity to the
top of the chimney can cause chronic or
occasional downdrafts. When selecting a site
for a new chimney, take care to consider the
placement of other objects in the vicinity of the
proposed chimney location.
WIND VELOCITY: Generally, the stronger and
steadier a wind, the stronger (better) the draft.
However, "gusty" wind conditions may cause
erratic downdrafts.

days. This is a weather-related phenomenon,
which generally is self-correcting as the
weather changes.
BRISKNESS OF FIRE: The hotter the fire in
your stove, the hotter your chimney and,
therefore, the stronger the draft.
BREAKS IN THE VENTING SYSTEM:
unsealed clean-out door at the bottom of the
chimney, leaky
stovepipe-to-thimble connection, or a leaky
chimney may cause inadequate draft.
SEASONAL FACTORS: Early fall and late
spring are generally difficult seasons in which to
establish proper drafts. The colder the outside
air (relative to room temperatures), the stronger
the draft.
