9 RECOMMENDATIONS FOR THE EXECUTION OF THE HYDRAULIC AND ELECTRIC SYSTEM
Installation must be done by a competent person, namely HETAS H004 qualified.
Before installing your central heating cooker we recommend that your flue outlet has a suitable
draught.
We recommend connecting the plant circulating pump to the central heating cooker’s control
panel.
We recommend installing non-return valves to prevent natural circulation phenomena
between the central heating cooker and the plant (see drawing par. 4.5 - 4.6 - 4.7 - 4.8 ). The
presence of open boilers causes natural circulation on the water surface with subsequent
oxygenation of the water. The presence of natural circulation produces condensation and can
consequently cause corrosion to parts of the central heating cooker.
We recommend you earth the central heating cooker and check the efficiency of the earthing
of the electrical system to which the central heating cooker is connected.
We recommend a magnetic cleaning system to make sure system fluid is optimum for
maximising performance and lifespan of product
Water treatment equipment is needed when: mains water has a hardness higher than
100mg/ml, this can be checked with your local water supply company or if private supply you
will need to check its quality.
Fitting a 3 way mixing valve (see below) to minimise condensate corrosion is mandatory, this
ensures the return water going into boiler is above 55c which drastically reduces the quantity of
acidic corrosion and therefore increases the lifespan of the product.
Minimum water pressure of 0.2 bar is needed
The safety heat exchanger cannot be used to produce domestic hot water
The appliance cannot be used “dry” i.e. with no water in it.
