1.Maximum permissible equivalent flue lengths are:-

Vertical Concentric

3m

Vertical Twin Pipe

12m*

*Both the air and flue duct can be up to 12 metres long each.

4.Any additional “in line” bends in the flue system must be taken into consideration. Their equivalent lengths are:-

Concentric Pipes:

45° bend

0.5 metres

93° bend

1.0 metres

Twin Flue Pipe

 

45° bend

0.25 metres

91.5° bend

0.50 metres

The elbow supplied with the standard horizontal flue is not included in any equivalent length calculations

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

Total Equivalent Length =

A+B+C+1x90°Bend

All vertical and angled runs must be included, measured from the boiler adaptor (point X) to the joint with the flue terminal (point Y). One 91.5° bend or two 45° bends can be included without reduction of the flue length.

If further elbows are required the flue length must be reduced by the following amounts:-

Roof

Terminal

660mm

The total equivalent length for this example is

1 metre for each 91.5° elbow

0.5 metre for each 45° elbow

C

= 6.5 metres.
