Flue Extraction
FACTORS AFFECTING FLUE SYSTEM
PERFORMANCE
DOWNDRAFT CONDITIONS
Downdraft is caused when air is forced back down the flue system
and into the oven cavity and room where the oven is situated.
This can be caused by environmental conditions acting on an
incorrectly positioned flue terminal. Downdraft is usually only
apparent in flue systems that do not include fan aided extraction.
EFFECTS FROM ENVIRONMENT
Incorrect exhaust draft direction
When wind blows across a building, it can cause a difference
in pressure between the entrance and exit of the flue. This will
depend upon the:
•
•
•
•
•
wind speed
direction of the wind
position of flue outlet in relation to the building
location of neighbouring buildings and structures
geographical features (e.g. hills and valleys).
These can cause or prevent a natural draft to occur in the flue.
Because of this it may cause any one of the following to occur:
• increased flow up the flue
• reduced flow up the flue
• intermittant downdraft.

ALWAYS ENSURE THAT
THE FLUE IS PERFORMING
CORRECTLY PRIOR TO USING
THE OVEN. IF THE FLUE IS NOT
PERFORMING CORRECTLY IT
CAN PUSH EMISSIONS BACK
DOWN INTO THE OVEN CAVITY
AND INTO THE ROOM WHERE
THE OVEN IS SITUATED.
Because of its nature, wind pressure on occasions can be greater
than the flue draught from open flues. To minimise this effect it is
important that you position the flue terminal where the effect of
the wind is minimised.
FAN AIDED EXTRACTION
If at any moment you believe that the fan is working incorrectly
and pushing emissions back down the flue system, you should
extinguish the oven and extraction immediately and seek further
assistance.
INCORRECT EXTRACTION POSES
A SERIOUS RISK OF CARBON
MONOXIDE POISONING.
