The termination of a natural draught flue
must be located in relation to neighboring
constructions so that wind from any
direction will not create down draught in
the flue. See diagrams this page.
Down-Draught
Reverse flow (down-draught) in the flue
occurs when pressure at the flue outlet is
greater than the inside of the heater. In
this condition, flue gases are discharged
through the down-draught diverted into
the room. This is of no consequence
where occasional wind conditions cause
small intermittent discharge.
down-draught and resultant discharge of
flue gas into living areas may cause user
discomfort.
Clause 5-13.6.2 of the AS5601 gas
installation standard
requirement only. It is good practice to
position the flue terminal above the roof
ridge line. The flue terminal must not be
sited adjacent to
parapets or, walls which may cause
pressure build up due to obstruction to
free flow of wind.
