Certikin - Genie Vertical Roof Terminal -  Suitable for Genie Boilers

The Vertical Roof Terminal is used as the final through-roof section of flue to pass through a roof vertically.

The maximum Flue Equivalent Length (FEL) permitted on the Genie Boiler is 20 metres horizontal or vertical.  Each flue section has its own FEL value - when designing your Flue system, you should add together the FEL for each section, and ensure the total value is under 20 metres.
