Horizontal

Flues

1.The standard flue is suitable only for horizontal termination applications.

		2. All fittings should be fully engaged. The approximate
	(ii)	engagement is 40mm. Apply soap solution to the seal on
	(ii)	each fitting to aid assembly.
		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 (i) to (ii) as shown.

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

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
