Any additional ‘in line’ bends in the flue system must be taken into consideration.
Their equivalent lengths are:
Concentric flue
The maximum equivalent lengths are 4m (horizontal and vertical).
These lengths exclude the standard elbow and flue/terminal assembly
(horizontal) and terminal assembly (vertical).
Concentric pipes:
135° bend 0.5m
93° bend 1.0m
Twin flue
The total maximum equivalent flue length is 75m.
Note: Air and flue tubes parallel.
Twin flue pipe:
135° bend (air duct) 1.3m
135° bend (flue duct) 2.6m
90° bend (air duct) 4.8m
90° bend (flue duct) 9.6m
Detailed examples of equivalent flue length calculations are given in the Installation
Guidance Notes for each flue system type (Documents 243501 and 243502 for
concentric and twin pipe respectively).
