WIND CONDITIONS
Wind causes pressure changes inside as well as outside a house. The design of the house can
influence the pressure environment around and in your home, the effect of wind on the home
can be complex and unpredictable. Care needs to be taken to ensure the flue termination is in
a good clear position. Your installer should be able to give advice on the best flue termination
position for your situation. Problems associated with wind noise or draft are almost never caused
by the wood fire itself and in general a flue that penetrates the roof near the peak and is more
than 600mm above the ridge is unlikely to be affected by wind.
PRESSURE DIFFERENTIAL, VENTING AND EXTERNAL AIR INTO THE
BUILDING
Negative house pressure is a common problem that can cause wood burning appliances to
have trouble lighting and performance issues, in some cases causing smoke to be spilled back
into the room. Kitchen and bathroom exhaust fans, air-conditioning units, and well-sealed,
insulated homes are more likely to have a negative pressure problem. Larger homes with
multiple levels are also likely candidates, however any house can have a negative pressure
problem. Care needs to be taken at the design or installation stage to ensure the building has
adequate ventilation to ensure draft in the flue system is always to the outside.
