8.1Horizontal Flue Systems

1.The standard flue is suitable only for horizontal termination

applications.

2. All fittings should be fully engaged. The approximate

engagement is 40mm. Apply soap solution to the seal on

each fitting to aid assembly.

3.Maximum permissible equivalent flue lengths are:-

(60/100) (80/125)

Horizontal Concentric 10 metres 20 metres

4. Any additional “in line” bends in the flue system must be

taken into consideration.

 

Their equivalent lengths are:-

 

Concentric Pipes:

 

135° bend

0.5 metres

93° bend

1.0 metres

Twin Flue Pipe

 

135° bend

0.25 metres

91.5° bend

0.50 metres

4. The elbow connected to the boiler adaptor is not included in any equivalent length calculations.

5. The illustrations opposite show examples of permissible flue systems.

NOTE: Flue length is measured from point X to Y as shown.

NOTE: Horizontal flue pipes should always be installed with a fall of at least 1.5°

from the terminal to allow condensate to run back to the boiler.

This bend is equivalent to 1 metre
