booklet to help you gain maximum if from your
appliance with minimum trouble.
1.1.1 Your Ravenheat Condensing Combination
Boiler has been designed to supply your Central

unit. When central Heating is operating, the
circulation will be interrupted when domestic hot
water is being drawn off. This will normally not
affect the level of the heating.

Below 150mm (6 inches)
Front 450mm (18 inches)
Sides 5mm (0.2 inches)
25mm (1 inch) at the front when installed
in a cupboard.
PLEASE NOTE
Due to the high efficiency and resulting low flue gas
exhaust temperature a white plume of condensation
vapour (cool steam) will be emitted from the flue 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.
1.2.1 Minimum clearances are required for safety and
maintenance.
