OMMISSIONING
INSTALLATION
Open the incoming stop valve and fi ll 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 1.5 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 1.5 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 BP 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 BP, 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 the
Technical Data section.
Primary Water System Treatment
Although the BoilerMate BP 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 the
Technical Data section.
Powerfl ushing/cleaning Of The Heating System
If it is proposed to ‘powerfl ush’ the heating system we would recommend that the
process used should always comply fully with the manufacturers instructions for the
powerfl ushing equipment being used.
If in any doubt please consult our Technical Helpline.
NOTE: With sealed heating systems air is
released from the water during the fi rst few
weeks of operation. This must be vented and
the system repressurised.
Commissioning Domestic Hot Water
System
The hot water fl ow temperature should settle
at about 55°C. Close this tap and open the hot
bath tap at maximum fl ow rate and record the
fl ow rate and the hot water temperature in the
‘Benchmark’ logbook.
Hand over to User
(a) Explain how to operate the heating and
hot water controls to the user. This should
include setting ‘on’ and ‘off’ times and the
room temperature on the room thermostat
as well as the use of thermostatic radiator
valves.
(b) Advise on boiler operation and maintenance
advised in the boiler manual.
(c) Handover appliance and room thermostat
user instructions and put the completed
“Benchmark” logbook and the appliance
instruction manual in the pocket on the
inside of the appliance front panel.
(d) DON’T place any clothing or other
combustible materials against or on top of
this appliance.
This product is covered by the ‘Benchmark’
scheme and a separate commissioning/
service log book is included with this
product. This must be completed during
commissioning and left with the product
to meet the Warranty conditions offered
by Gledhill.
These Instructions should be placed along with
the component manufacturers instructions in
the pocket provided. The front panel should
then be refi tted.
