Conventional Draught Stabilizer
The flue stabilizer works by opening to provide an additional air supply to the flue whenever the flue’s
negative pressure reaches its upper limit and so checks any rise beyond this limit to maintain the
correct negative pressure within the stove. This system of flue control is universally accepted as both
effective and reliable, or the flue itself is of higher efficiency than normal, the stabilizer may be unable
to supply sufficient air to reduce the negative pressure adequately, or be needlessly wasting room
heat by having to supply dilution air constantly. The Harmony oil stove can be supplied with two sizes
of governing plates which may be fitted to the stove’s flue spigot, if during commissioning the flue
is found to be subjecting the stove to a negative pressure which is too high for efficient combustion
or the longevity of the stove.
