FLUE SYSTEM GENERAL REQUIREMENTS

Install the horizontal flue components with an angle of 3° back in the direction of the boiler (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.
EcoShield™ 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.
EcoShield™ Water heaters 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.
