FLUE SYSTEM

G
ENERAL
The Water heater has a positive pressure flue system. The available combined pressure drop for the inlet and outlet system is 200 Pa for the
complete Water heater range.
Install the horizontal flue components with an angle of 3° back in the direction of the Water heater (roughly equal
to five centimetres for every linear meter). Failure to install the flue correctly will result in a build-up of condense
within the flue pipework that will cause early component failure.
When using a wall terminal, there is the possible risk of ice building-up on surrounding parts/structures, because
the condensate will freeze. This risk should be taken into account during the design phase of the heating
installation.
EF Water heaters will produce large condense clouds especially during cold weather, consideration must be taken
as to whether this will cause a nuisance to neighbouring properties and if so alternative flue arrangements used.
The EF Water heater can operate with very low flue temperatures; as such the flue system used must be suitable
for use with condensing appliances made from either Polypropylene or stainless steel and have a temperature
class of T120.
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.
Before installation of any flue system read the installation manual carefully for both the appliance and flue system
to be used. Information on the flue system Supplied by Lochinvar can be found within this manual.
