The following criteria should be noted when planning the
installation.
•
The concentric flue system must be inclined at 3º
(52mm per metre) from the appliance, to allow
condensate to drain back into the boiler.
•
Because the appliance operates at high efficiency a
white plume of condensation will be emitted from the
terminal. Care must be taken when selecting the flue
terminal position (see pages 18 - 19).
