BREAKS IN THE VENTING SYSTEM:
An unsealed
clean-out door at the bottom of the chimney, leaky
stovepipe joints, a poor 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.
Operating the Stove
There are days when a draft is not easily established. As
outlined above, seasonal factors or a cold chimney may be
the cause. Try starting the fire by using small kindling
and fuel to obtain a quick, hot fire. Tend the fire
frequently with small fuel until the chimney is hot and the
draft is well established.
