Sides 5mm (0.2 inches)
25mm (1 inch) at the front when installed
in a cupboard.
PLEASE NOTE
Due to the high effi ciency and resulting low fl ue gas
exhaust temperature a white plume of condensation
vapour (cool steam) will be emitted from the fl ue outlet
terminal, this is quite normal. It will be particularly
evident during periods of low outdoor temperatures or
when the boiler is working at its optimum performance.
