If it is found that there is excessive draught in the chimney then either an adjustable flue
damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper
should not close off the flue entirely but should in its closed position leave a minimum
continuous opening free area of at least 20 % of the total cross sectional area of the flue or
fluepipe.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping
the chimney and connecting fluepipe.
You should also familiarise yourself with the draught conditions for chimneys with 2 flues.
The flue outlet spigot is 150 mm in diameter.
For strong draughts, the chimney or flue should be fitted with a draught stabiliser. In which
case, it is important to ensure that there is a free flow-through area of minimum 20 cm² when
the regulating gate is shut. Otherwise, the fuel energy may not be used optimally. If, at any
time, you are unsure about the condition of the chimney, you should contact a chimney
sweep.
Remember that access to the access door should be kept clear.
