Condensing Boiler Installation Requirements - WarmFlow Utility U70HE User Manual

CONDENSING BOILER INSTALLATION
The Warmflow condensing boiler can be fitted to most installations using
standard practices and techniques.
There are however a number of considerations that must be taken into
account.
. All existing systems must be properly flushed to remove any sediment/
sludge in order to prevent any blockage or reduction in efficiency of the
boiler.
2. The system must be fully pumped.
3. The primary difference between an ordinary boiler and a condensing
boiler is the condensate drain. The drain can be plumbed from the
condensate trap in any ordinary plastic pipe, eg, plastic overflow pipe,
directly into the household drain or soak away.
Any blockage in the drain could lead to an alteration in the combustion
settings because of partially blocked flueways.
Where the boiler is fitted into a basement a condensate pump may be
required.
4. As an indicator of the increased efficiency of a condensing boiler there
may be a visible plume of 'steam' from the flue. Care needs to be
exercised when positioning the appliance and selecting the type of flue
to ensure that the plume does not cause a nuisance to the householder
or to surrounding properties.
As the water temperature in the system rises the pluming effect will
diminish. Even where pluming is not visible the boiler is still operating
more efficiently than a standard boiler.
