Good draft also depends on a sufficient supply of air
to the stove. The chimney cannot pull more air than is
available. Sluggish draft can be caused by a house that
is tight enough to prevent the ready flow of air to the
stove, or by competition between the stove and other
appliances that vent indoor air to the outside; i.e., ex-
haust fans for range hoods, clothes dryers, bathroom,
etc. If the chimney draws well when all such equipment
is turned off (or sealed, in the case of the fireplaces
and/or other stoves), you simply need to be attentive
in timing the use of the other appliances. If you need
to crack a nearby window or door to enable the chim-
ney to pull well, you should install an outside-air intake
to bring combustion air directly to the stove. Consult
your Vermont Castings' dealer regarding an adapter to
attach to the stove to connect an air duct for outdoor
combustion air.
In many cases, local or national codes require the
installation of permanently open air vents, particularly
with larger appliances (i.e. above 5 kW). Refer to these
codes to determine specific requirements for your
installation.

conclusion
Woodburning is more an art than a science. Art in-
cludes technique and since installations, homes and
fuel vary, the stove operator must also vary technique,
(mostly timing), to achieve satisfying results. Over
time, you will become familiar with the intricacies and
nuances of your particular installation and you will be
able to identify cause and effect in a variety of seasonal
circumstances.
