8.2 Flue Lengths
The standard horizontal telescopic flue kit allows for lengths
between 315mm and 500mm from elbow to terminal (Fig. 14).
Extensions of 250mm, 500mm & 1m are available.
The maximum permissible equivalent flue length is:
10 metres (60/100 system - vertical & horizontal)
20 metres (80/125 system - vertical & horizontal)
15 metres (80/80 twin pipe)
8 metres (60/100 system - vertical connected to
ridge terminal)
For details of Plume Displacement Kit lengths see the Flue
Installation Guide supplied in the literature pack.
8.3 Flue Trim
1. The flexible flue trims supplied can be fitted on the outer and
inner faces of the wall of installation.
8.4 Terminal Guard (Fig. 15)
1. When codes of practice dictate the use of terminal guards,
‘Multifit’ accessory part no. 720627901 can be used (Note: This
is not compatible with Flue Deflector referred to below).
2. If a proprietary guard is used it must be identified as suitable
for use with condensing boilers.
3. There must be a clearance of at least 50mm between any part
of the terminal and the guard.
4. The flue terminal guard should be positioned centrally over the
terminal and fixed as illustrated.
8.5 Flue Deflector (Fig. 16)
1. If required, push the flue deflector over the terminal end and
rotate to the optimum angle for deflecting plume. Secure the
deflector to the terminal with screws provided.
8.6 Flue Accessories
