User's
Introduction
The
icos system
is a wall mounted, room sealed, condensing
boiler, featuring full sequence automatic spark ignition and fan
assisted combustion.
Due to the high efficiency of the boiler, condensate is produced
from the flue gases and this is drained to a suitable disposal
point through the plastic waste pipe at the lower rear of the
boiler. A condensate 'plume' will also be visible at the flue
terminal.
Safety
Current Gas Safety (Installation & Use)
Regulations or rules in force.
In your own interest, and that of safety, it is the law that this boiler
must be installed by a CORGI registered installer.
In IE the installation must be carried out by a competent person
and installed in accordance with the current edition of I.S. 813

Electricity Supply
This appliance must be earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
Connection must be made in a way that allows complete
isolation of the electrical supply such as a double-pole switch,
having a 3mm (1/8") contact separation in both poles, serving
only the boiler and system controls. Alternatively, a 3-pin
UNSWITCHED socket may be used. The means of isolation
must be accessible to the user after installation.
