The EF Water heater can be installed on to a common flue system if required. The common flue system should be sized to operate under a
negative pressure of -0.03 to -0.10 mbar.
If a positive pressure common flue system is to be used, a proprietary recirculation prevention device must be installed at the flue spigot of
each Water heater to prevent products of combustion from re-entering the plant room.
A cascaded common flue system which operates on a positive pressure is available from Lochinvar Limited. Further details can be found in
the Cascade Flue Systems guide, available from
www.lochinvar.Limited.uk .

If a Vertical flue terminal is to be fitted less than 2 metres from ground level or in a location where it can be touched from a window, door or
balcony, a terminal guard must be fitted.
The terminal guard should be positioned centrally around the terminal and secured using appropriate wall fixings.

For flue runs of less than 6 metres, provided that the flue system rises at an angle of at least 3

(50mm per metre), no additional condensate
drain will be required. Failure to provide an adequate rise in the flue system may lead to pooling of condensate which may lead to premature
failure of the flue system.
If the flue run is greater than 6 metres, it is recommended that an inline condensate drain and trap be fitted. The condensate trap should be
connected to a suitable drainage system as described in Section 6.2

Aluminium flue pipe must not be used on this appliance as it may lead to premature failure of the heat exchanger
and will invalidate the warranty.
