2.3 COMMISSIONING
2.0 INSTALLATION
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
system, including the boiler and BoilerMate OV, 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.
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 - see section 1.2 Technical
data for volumes.
In most cases the quantities shown opposite
will be adequate for up to a typical 3/4
bedroom property.
Primary Water System Treatment
Although the BoilerMate has no special 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 such as
Fernox MB1.
When determining the quantity of inhibitor
required, be sure to allow for the increased
volume of water in the primary circuit due to
the thermal store - see section 1.2 Technical
Data for volumes.
In most cases the quantities shown opposite
will be suitable for up to a typical 3/4 bed
property.
POWERFLUSHING/CLEANING OF THE HEATING
SYSTEM
If it is proposed to ‘powerflush’ the heating
system we would recommend that the
BoilerMate appliance is isolated from the
heating system being cleaned. Failure to do this
could seriously damage the appliance.
When carrying out the work always comply
fully with the manufacturers instructions for
the powerflushing equipment being used.
If in any doubt please consult our Technical
Helpline.
