OMMISSIONING
Domestic Water and Heating Systems
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 cisterns.
Check the water level in the feed and expansion cisterns 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 A-Class OV SOL, 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 for system preparation/water treatment and
commissioning are given in the Domestic Heating Compliance Guide.
When using either cleansing or corrosion inhibitor chemical, the manufacturers
instructions must be followed.
Although the BoilerMate A-Class OV SOL has no special water treatment requirements
because of the nature of materials in these systems, we recommend the use of a
cleansing agent as well as a corrosion inhibitor. We generally recommend the use of
Fernox products with the BoilerMate A-Class OV SOL appliances.
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 the Technical data
section for volumes.
In most cases the quantities shown opposite will
be adequate for a typical installation.
Primary Water System Treatment
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 the Technical data
section for volumes.
In most cases the quantities shown opposite will
be suitable for a typical installation.
Failure to adequately clean and inhibit
the heating system will lead to problems
which will not be covered by the appliance
warranty.
POWERFLUSHING/CLEANING OF THE
HEATING SYSTEM
If it is proposed to ‘powerflush’ the heating
system the BoilerMate appliance must be
isolated from the heating system being
cleaned. Failure to do this could seriously
damage the appliance. Therefore, any
damage caused to the appliance during
powerflushing will not be covered by the
appliance warranty.
Note: Do not plug the cold feed/open vent
to carry out powerflushing as this will also
cause serious damage to 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.
