The following criteria should be noted when planning
the installation:
The concentric fl ue system must be inclined at
3º (52mm per metre) from the appliance, to allow
condensate to drain back into the boiler
A white plume of condensation will be emitted from
the terminal because the appliance operates at high
effi ciency. Care must be taken when selecting the fl ue
terminal position
To achieve a maximum fl ue length, one of the extension
fl ue kits will need to be cut so that the permitted
maximum fl ue length is not exceeded
Horizontal fl ue options 1-6 illustrate common fl ue
installations. Other confi gurations of the fl ue system are
possible up to, and not exceeding, the stated maximum
fl ue lengths.
