6.0 COMMISSIONING
6.0 COMMISSIONING
(a) it is essential that the system functions properly for optimum performance. To
achieve this, the heating and the hot water system should be commissioned in
accordance with the good practice and generally 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.
(b) WARNING: Do not attempt to start this appliance unless the appliance and the
heating system have been filled with water and thoroughly vented.
6.1 INITIAL SYSTEM FILLING
(a) Open the cold water stop cock on the inlet to the appliance and allow water to
flow through the F & E cistern/appliance to all the domestic water taps. Ensure
all air is vented and there are no leaks.
(b) Check and adjust if necessary the air pressure in the heating expansion vessel.
(c) Fill the sealed heating system in the normal way through the temporary filling
loop to the pressure required.
(d) Vent as necessary and then check the whole of the primary heating and domestic
hot and cold distribution system for leaks,
(e) When the system is full check if the water level in the F & E cistern is correct and
adjust the ball valve if necessary.
(f ) Check the functioning of the overflow/warning pipe and regulate the service valve
so that in a fault condition, the warning/overflow pipe can carry the maximum
water supply into the F&E cistern.
6.2 CLEANSING AND WATER TREATMENT
6.2.1 WATER TREATMENT
Although the BoilerMate has no special water treatment requirements, the radiators
and other parts of the system will benefit from the application of scale and corrosion
inhibitor such as the 'Fernox Superfloc' cleaning agent and Fernox MB1 protector.
The correct use of cleaning agent and of the correct strength of inhibitor is essential
for the efficient and long life of the complete system. Failure to do this correctly will
result in premature corrosion of the boiler/blocking of the waterways and neither of
these situations will be covered by the appliance warranty.
The correct quantities of cleaning and treatment agents should be determined from
manufacturer's instructions.
(a) Ensure that all cleansing/treatment of the heating system is carried out fully in
accordance with the instructions provided by Fernox.
(b) The water system must be thoroughly flushed out, initially with cold water and
ensuring that all valves are fully open.
(c) Refill the system to normal working pressure. Examine for water leaks. Rectify if
necessary.
(d) Add Fernox Superfloc Cleansing Agent to ensure that all flux residues and
installation debris are removed from the system.
(e) Heat the system to full operating
temperature and check for water leaks
and rectify if necessary. Flush the system
again until it is clean.
(f ) Refill the system and add Fernox MB1
Protector to the system ensuring that the
system is fully vented.
6.2.2 POWER
FLUSHING/CLEANING
OF THE HEATING
SYSTEM
(a) When carrying out the work, always comply
fully with the manufacturers' instructions
for the power flushing equipment.
(b) We would always recommend that the
BoilerMate is isolated from the heating
system being cleaned. if in any doubt,
please consult our Technical Help line.
6.2.3 CLEANSING HOT
& COLD WATER SYSTEM
TREATMENT
(a) Fully flush and if necessary chlorinate the
hot and cold water system in accordance
with the recommendations in the Model
Water Bylaws and BS 6700.
