STOVE AND CHIMNEY WEATHER CONDITIONS
Using the Stove and Chimney Function in Various Weather Conditions
The performance of your stove is heavily in昀氀uenced by weather conditions and the functionality of your
chimney. Wind, fog, mist, and cold temperatures can all impact the chimney draught and, consequently,
how your stove operates. Under varying wind loads, you may need to adjust the air昀氀ow settings to
maintain good combustion. Similarly, in adverse weather conditions such as fog or low temperatures, you
may need to use different air control settings to achieve optimal performance.
The chimney acts as the stove’s motor, with its draught determining how effectively your stove will work.
Chimney draught creates negative pressure in the stove, which pulls smoke out of the appliance and
draws in air through the combustion air damper. This air fuels combustion and supports the air wash
system to keep the stove glass clear of soot. The draught is created by the temperature difference
between the inside and outside of the chimney, the greater the difference, the stronger the draught.
For ef昀椀cient operation, it is essential to bring the chimney up to operating temperature as quickly as
possible, especially on days with poor draught due to adverse weather. Steel chimneys heat up faster
than brick chimneys, which take longer to reach operating temperature. Achieving the right temperature
ensures the stove operates effectively and reduces the need for excessive air adjustments.
On days with poor draught, it is crucial to establish a few strong 昀氀ames quickly. To do this, use extra
昀椀relighters, chop the wood into smaller pieces, and maintain air昀氀ow settings to boost combustion until
the chimney reaches operating temperature. Properly managing your chimney and stove settings under
various weather conditions ensures safe and ef昀椀cient operation.
