Open the incoming stop valve and fill the domestic mains cold and hot water
systems.
Fill the whole of the primary heating system with potable water through the
feed and expansion cistern.
Check the water level in the feed and expansion cistern and adjust the ballvalve
if necessary.
Check the whole of the primary heating and domestic hot and cold distribution
systems for leaks.
It is essential that all systems function properly for optimum performance.
To achieve this, the primary system should be commissioned in accordance with
good practice and generally in accordance with the requirements of BS 6798,
BS 5449 and BS 7593.
Full details of the requirements are given in PAS 33:1999 under Section 10
Commissioning.

2.3 COMMISSIONING
When using either cleansing or corrosion
inhibitor chemical, the manufacturers
instructions must be followed.
Cleansing the Primary System
When determining the quantity of cleanser
required, be sure to allow for the increased
volume of water in the primary circuit due
to the thermal store.
In most cases the quantities shown opposite
will be adequate for a typical 3/4 bedroom
property.
Primary Water System Treatment
Although the BoilerMate 2000 has no special
t
e h
s
s y
e t
m
water treatment requirements, the radiators
and other parts of the circuit will benefit
from the application of a scale and corrosion
inhibitor such as Sentinel X100 or a Protector
a
e g
t n
such as Fernox MB1.

SYSTEM
If it is proposed to 'powerflush' the heating
system we would recommend that the
t
e h
s
s y
e t
m
BoilerMate appliance is isolated from the
heating system being cleaned. Failure to do
this could seriously damage the appliance.
t n
When carrying out the work always comply

p
e

fully with the manufacturers instructions for
the powerflushing equipment being used.
