7.9 Flue Dimensions
See Section 1.2. The standard horizontal flue kit
allows for flue lengths between 270mm and
800mm from elbow to terminal (Fig. 11).
The maximum permissible equivalent flue
length is: 4 metres horizontal (Fig. 12).
NOTE: Each additional 45° of flue bend will
account for an equivalent flue length of 0.5m.
eg. 45° = 0.5m,

terminal guards, they can be obtained from most
Plumbers' and Builders' Merchants.
2. There must be a clearance of at least 50mm
between any part of the terminal and the guard.

3. When ordering a terminal guard, quote the
appliance name and model number.
