7.10 Flue Dimensions
See Section 1.2. The standard horizontal flue kit allows for
flue lengths between 270mm (10 5/8") and 800mm (32")
from elbow to terminal
(Fig. 18).
The maximum permissible equivalent flue length is:
4 metres (Fig. 18a).
NOTE: Each additional 45º of flue bend will account for an
equivalent flue length of 0.5m
eg. 45º = m, 90º = 2 x 45º = 1m etc.
