1. INTRODUCTION
The Logic + System S is a system boiler, featuring full sequence
automatic spark ignition and fan assisted combustion. It is
designed to provide central heating and hot water when a separate
hot water cylinder is installed.
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
a plastic waste pipe at the base of the boiler. A condensate ‘plume’
will also be visible at the flue terminal.
