Introduction

The 

excel HE 

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 

excel HE 

is a combination boiler providing both central

heating and domestic hot water on demand.
