5.3.8 Horizontal Flue/Chimney Systems

1. The standard telescopic flue is suitable only for horizontal

termination applications. It allows for lengths between 315mm

and 500mm from elbow to terminal without the need for cutting

(Fig. 14). Extensions of 250mm, 500mm & 1m are available.

2. All fittings should be fully engaged. The approximate

engagement is 40mm. Apply the lubricant supplied to the seal on

each fitting to aid assembly.

3. Maximum permissible Horizontal Concentric equivalent flue

lengths are:-

(60/100) (80/125)

6 metres 12 metres

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

into consideration. Their equivalent lengths are:-

135° bend 0.5 metres

93° bend 1.0 metres

5. The elbow supplied with the standard horizontal telescopic

flue kit is not included in any equivalent length calculations.

Flue length is measured from point (i) to (ii) as shown

below.

Read this section in conjunction with the Flue

Accessories & Fitting Guide supplied with the boiler. That

document includes details of vertical flue/chimney systems and

Plume Displacement Kits.
