Introduction
The isar is a wall mounted, room sealed, condensing
combination 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.
The isar is a combination boiler providing both central heating
and instantaneous domestic hot water.
