Before Installation
5.2.3 Hard Water Areas
1. If the area of the installation is recognised as a HARD WATER
AREA then this must be taken into account when filling the system.
5.2.4 Bypass
1. Where a system employs TRV’s on all radiators and includes
two port zone valves an automatic bypass must also be fitted to
protect system components.
2. Existing systems with a 3 port valve may not require a bypass
depending on type of radiator valves fitted.
3. Current editions of Building Regulations and Central Heating
System Specification documents give additional guidance.
5.2.5 System Control
1. The system must be fitted with thermostats and TRVs to comply
with Part L of the Building Regulations.
5.2.6 Treatment of Water Circulating Systems
1. All recirculatory water systems will be subject to corrosion unless
they are flushed and an appropriate water treatment is applied. To
prevent this, follow the guidelines given in BS 7593 “Treatment of
Water in Domestic Hot Water Central Heating Systems” and the
treatment manufacturers instructions.
2. Treatment must involve the use of a proprietary cleanser, such
as Sentinel X300 or X400, or Fernox F3 and an inhibitor such as
Sentinel X100 or Fernox MB-1.
3. Full instructions are supplied with the cleansing products, for
further information contact Sentinel (0800 389 4670) or Fernox
(0870 870 0362).
Failure to flush and add inhibitor to the system will
invalidate the appliance warranty.
4. Artificially softened water MUST NOT be used in the system.
5. It is important to check the inhibitor concentration after
installation, system modification and at every service in
accordance with the inhibitor manufacturer’s instructions. (Test kits
are available from inhibitor stockists.)
6. Complete the label supplied with the inhibitor and attach to the
inside of the boiler case. Detail of system treatment should be
added for future reference.
