WATER TREATMENT
CENTRAL HEATING
The ESPRIT 2 range of boilers have an ALUMINIUM
alloy heat exchanger.
IMPORTANT.
The application of any other treatment to this product
may render the guarantee of Ideal Stelrad Group.
Ideal Stelrad Group
recommend Water Treatment in
accordance with the Benchmark Guidance Notes on
Water Treatment in Central Heating Systems.
If water treatment is used
Ideal Stelrad Group
recommend
only the use of
FERNOX or MB1, SENTINEL X100
or Salamander
Corrosion Guard inhibitors and associated water treatment
products, which must be used in accordance with the
manufacturers' instructions.
Notes.
1.
It is most important that the correct concentration of the
water treatment products is maintained in accordance with
the manufacturers' instructions.
2.
If the boiler is installed in an existing system any unsuitable
additives MUST be removed by thorough cleansing. BS
7593:1992 details the steps necessary to clean a domestic
heating system.
3.
In hard water areas, treatment to prevent lime scale may be
necessary - however the use of artificially softened water is
NOT permitted.
4.
Under no circumstances should the boiler be fired before
the system has been thoroughly flushed.
DOMESTIC HOT WATER
In hard water areas where main water can exceed 200ppm
Total Hardness (as defined by BS 7593:2006 Table 2) a
scale reducing device should be fitted into the boiler cold
supply within the requirements of the local water company.
The use of artificially softened water, however, is not
permitted.
Ideal Stelrad Group
recommend the use of Fernox
Qantomat, Sentinel Combiguard and Calmag CalPhos I
scale reducing devices, which must be used in accordance
with the manufacturers' instructions.
