INTRODUCTION
The Logic + Combi 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 a plastic waste pipe at the base of the boiler. A condensate 'plume' will also be visible at the flue terminal.
The Logic + Combi is a combination boiler providing both central heating and instantaneous domestic hot water.
