icos system - Installation and Servicing
Note.
A flat or pitched roof flashing plate (not supplied) is required before
proceeding with the installation of this kit.
This kit is suitable for both flat and pitched roof terminations, using a
concentric flue to run vertically from the top of the boiler and terminating
above roof level.
Connection to the top of the boiler is made using both a separately
supplied vertical connector and a 80/125 adaptor.
WEATHER PROOFING
Where the flue passes through the roof line an
adequate seal must be made. This is
achieved by using either:
- Flat roof weather collar
or
- Universal weather collar.
ACCESSORIES
Flue Duct Extension Kits are available for
flue lengths extending beyond 1m. These
packs contain 1m extension ducts and
may be cut to the desired length.
If the offset vertical option is used an
elbow Kit is required. For a full
accessories list refer to page 7, Optional
Extras and Frame 31, Flue Arrangement.
