2.3 COMMISSIONING
2.0 INSTALLATION
Open the incoming stop valve and fill the domestic mains cold and hot water
systems.
Check and adjust as necessary the expansion vessel air pressure to the fi gure specifi ed
(normally 1.0 bar).
Fill the whole of the primary heating system with potable water through the fi lling
loop provided adjacent to the boiler to the pressure required (normally 1.0 bar).
During fi lling vent air as necessary from the high points of the system including the
manual air vents provided on the appliance and the feed to the expansion vessel.
Fill the appliance i.e. BoilerMate A-Class through the feed and expansion cistern fl ush
and refi ll.
Check the water level in the feed and expansion cistern and adjust the ballvalve if
fi tted.
Check the warning pipe (if fi tted) is installed correctly, has a continuous fall and is not
blocked i.e. discharges water freely.
Check the whole of the primary heating and domestic hot and cold distribution
system, including the boiler and BoilerMate SP, 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
It is very important to ensure that the Primary system is cleaned using a suitable
cleansing agent such as Sentinel X300 or Fernox Superfl oc to ensure that any fl ux
residues/installation debris are removed.
The volumes/concentration should be calculated in accordance with the manufacturers
instructions allowing the volume for the primary coil shown in the Table in 1.2 Technical
Data.
Primary Water System Treatment
Although the BoilerMate A-Class SP has no special water treatment requirements, the
radiators and other parts of the circuit will benefi t from the application of a scale and
corrosion inhibitor such as Sentinel X100 or a Protector such as Fernox MB1.
The volumes/concentration should be calculated in accordance with the manufacturers
instructions allowing the volume for the primary coil shown in the Table in 1.2 Technical
Data.
POWERFLUSHING/CLEANING OF THE HEATING
SYSTEM
If it is proposed to ‘powerfl ush’ 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 powerfl ushing equipment being used.
If in any doubt please consult our Technical
Helpline.
