Where both lengths have been determined they can be applied to the graph to check that the installation is permissible. For example, if it was known that 2 metres of concentric
flue and 2 metres of 60Ø exhaust were required, the values could be applied to the graph as shown in
Example 2 . As the point of intersection of the dotted lines is below the solid
diagonal line, the combination of lengths is shown to be acceptable.
Example 3 ­ Flue Lengths OK
In the example shown, assume that the concentric part of the flue needs to be 1.6 metres long. Find the position of '1.6' on the horizontal axis of the graph and then project
upwards to the solid diagonal line. This is represented by the vertical thick dotted line. Where this dotted line intersects with the solid diagonal line on the graph, project across to
the vertical axis. As can be seen this corresponds with 4.0 metres. Therefore, the total equivalent length of the 60Ø exhaust can be up to 4.0 metres. Any elbow equivalencies
must be accounted for i.e. 93° elbows are equal to 1 metre, each 45° elbow to 0.5 metres.

Flue Length ­ Worked Example
In the diagram ( Fig. 21f ) above an additional 93° elbow and pair of 45° elbows have been included in the 60Ø exhaust.
Also 1 straight extension piece has been used.
To calculate total length:­
Length of 60Ø supplied in kit = 1 metre
1 metre Extension = 1 metre
1 x 93° Elbow = 1 metre
2 x 45° Elbow = 1 metre (0.5 metres each)
Total 60Ø = 4 metres
After consulting the table in Example 3 it can be determined that the concentric flue could be up to approximately 1.6 metres long.
