(80/125)

Vertical Concentric

10 metres

20 metres

2.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

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

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

IMPORTANT: All flue systems must be securely supported at least once every metre. Suitable pipe supports are available as accessories.

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 135° 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:-

 

 

 

 

 

 

 

 

1 metre for each 91.5° bend
