If it is found that there is excessive draughtin the chimney then either an adjustable flue damper or alternatively a
draughtstabiliser shouldbe fitted. Theadjustable flue damper should not close off the flue entirely but should in its
closed positionleave a minimum continuousopening free area of at least 20 % of the total crosssectional area of
the flue or fluepipe.
Adequateprovisione.g.easily accessiblesootdoor ordoors must beprovidedfor sweeping the chimneyand
connecting flue pipe.
