Introduction
The icos is a wall mounted, room sealed, super efficient
condensing boiler featuring full sequence automatic spark
ignition and fan assisted combustion.
Due to the very high efficiency, condensate is produced from
the flue gases and this is drained to a suitable disposal point
through the plastic waste pipe at the right lower rear of the
boiler. A condensate 'plume' will also often be visible at the
flue terminal.
