2 CONDENSING BOILER INSTALLATION REQUIREMENTS
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.
1. 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.
