1 INTRODUCTION
1.1 Please carefully read the information in the
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
Heating and Domestic Hot Water directly from one
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.
1.2 CLEARANCES AROUND THE BOILER
Above 125mm (5 inches)
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 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.
1.2.1 Minimum clearances are required for safety and
maintenance.
Do not obstruct any purpose made ventilation opening
if boiler has been fi tted in a compartment. Never hang
clothes, etc., over the appliance.
