Pre-Installation
4.1.5

Inhibitor

Add a suitable inhibitor or combined inhibitor/anti-freeze, if the system
is exposed to freezing conditions, to the heating system in accordance
with the DWTA code of practice and manufacturer's guidelines.
The inhibitor or combined inhibitor/anti-freeze must not
cause damage to the materials within the boiler (mild
steel, stainless steel, copper and brass) and any other
materials/components within the system.
▶ The concentration level of inhibitor in the system
should be checked every 12 months or sooner if
system content is lost.
WARNING: Sealing agents
▶ In cases where all attempts to find a system micro
leak have failed, Worcester, Bosch Group supports
the use of Fernox F4 leak sealer.

4.1.6

Artificially softened water

It is possible to have an ion exchange water softener fitted to the cold
water system of the property. However, the boiler requires an untreated
cold water connection taken from the mains supply, before the water
softener, to the primary water filling point of the heating system.
Alternatively there are water softening/treatment devices that do not
adjust or alter the pH levels of the water. With these devices it may not
be necessary to provide an untreated water by-pass to the primary water
filling point of the heat system.
NOTICE:
▶ Salt based, softened water must not be used to fill
the central heating system.

Table 4 Key to oil supply feed system
4.3.1

Single pipe gravity feed system:

The oil storage tank [1] must be positioned so that the oil level does not
exceed 4 metres above the level of the burner oil pump [9] and in
addition the oil level must be at least 300mm above the oil pump [9].
Where the maximum oil level in the oil storage tank exceeds 4 metres, a
head breaking device must be installed between the tank [1] and the
burner oil pump [9].
