WATER TREATMENT
The istor boiler has an ALUMINIUM alloy heat exchanger
IMPORTANT.
The application of any other treatment to this
product may render the guarantee of Ideal Stelrad
Group invalid.
Ideal Stelrad Group recommend Water Treatment in
accordance with the Benchmark Guidance Notes on
Water Treatment in Central Heating Systems. Ideal
Stelrad Group recommend only the use of
or MB1, GE BETZ SENTINEL X100
Guard inhibitors and associated water treatment products,
which must be used in accordance with the
manufacturers' instructions.
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, GE Betz Sentinel Combiguard and Calmag
CalPhos I scale reducing devices, which must be used in
accordance with the manufacturers' instructions.

Installation and Servicing
These valves should now be left as set.
2. Open all manual or thermostatic radiator valves and
adjust the lockshield valves on the remaining radiators,
o
to give around 15
C temperature drop at each radiator.
3. Adjust the room thermostat and programmer to NORMAL
settings.

Notes.
1. It is most important that the correct concentration of the
water treatment product 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. 7593:2006 details the steps necessary to
clean a domestic central 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.
