5 COMMISSIONING & OPERATION
NOTE: please refer to 3 - 3E and use the appropriate PPE
when carrying out any of the actions or procedures contained
within this section.
5.1 GAS SUPPLY INSTALLATION
Inspect the entire installation including the gas meter, test for
tightness and purge. Refer to BS 6891 (I.S. 813 in ROI) for
specific instruction.
5.2 THE HEATING SYSTEM
The appliance contains components that may become damaged
or rendered inoperable by oils and/or debris that are residual
from the installation of the system, consequently it is essential
that the system be flushed in accordance with the following
instructions.
5.3 INITIAL FILLING OF THE SYSTEM
Ensure both flow and return service valves are open, remove
appliance casing as described in 4.6, identify the automatic air
release valves (AAV) and loosen the dust cap/s by turning the
cap anti-clockwise one full turn. Ensure all manual air release
valves located on the heating system are closed. Connect the
filling loop (not supplied), slowly proceed to fill the system by
firstly opening the inlet valve connected to the flow pipe, and
then turning the lever on the fill valve, to the open position. As
water enters the system the pressure gauge will begin to rise.
Once the gauge has reached 1 BAR close both valves and begin
venting all manual air release valves, starting at the lowest first.
It may be necessary to go back and top-up the pressure until
the entire system has been filled. Inspect the system for water
tightness, rectifying any leaks.
5.4 INITIAL FLUSHING OF THE SYSTEM
The whole of the heating system must be flushed both cold
and hot as detailed in 5.6. Open all radiator or heating valves
and the appliance flow & return service valve. Drain the boiler
and system from the lowest points. Open the drain valve full
bore to remove any installation debris from the boiler prior to
lighting. Refill the boiler and heating system as described in 5.3.
5.5 PRELIMINARY CHECKS
Before starting up the boiler, check:
- confirm via the appliance data badge, that the appliance is
suitable/configured for the gas type and electrical supply
that has been provided to the appliance
- inspect the entire flue system and ensure that it has been
installed in accordance with these instructions and the
relevant standards that apply locally and/or nationally
- that the required clearances have been met in respect of the
requirements for maintenance
- inspect the entire installation including the gas meter, test
for tightness and purge. Refer to BS 6891 (I.S. 813 in ROI)
for specific instruction
- ensure that the rated delivery of the gas meter is adequate
enough to serve this appliance and any other gas appliance
connected to the same meter
- ensure that the gas supply pipework is of adequate size to
provide the maximum gas rate required by this appliance
- check that the siphon is completely filled with water,
otherwise fill it up (see chapter 5.7).
5.6 FINAL FLUSHING OF THE HEATING
SYSTEM
The system shall be flushed in accordance with BS 7593 (I.S.
813 ROI). Should a cleanser be used, it must be suitable for
stainless-steel heat exchangers. It shall be from a reputable
manufacturer and shall be administered in strict accordance with
the manufacturers' instructions and the DWTA code of practice.
NOTE: Chemicals used to cleanse the system and/or inhibit
corrosion must be pH neutral, i.e. they should ensure that the
level of the pH in the system water remains neutral. Premature
failure of certain components can occur if the level of pH in the
system water is out-with normal levels.
5.6.1 INHIBITORS
See Section 3 "General Requirements".
5.7 FIRST COMMISSIONING
On first ignition after prolonged inactivity and after maintenan-
ce, before putting the appliance into operation it is essential to
fill the condensate collection siphon by pouring about 1 litre of
water into the boiler combustion analysis take-off and check:
- that the float within the trap is free and moving
- the correct flow of water from the boiler outlet discharge
pipe
- there are no leaks of the condensate drain connection line.
Correct operation of the condensate drain circuit (siphon and
pipes) requires that the condensate level does not exceed the
maximum level (max). Prior filling of the siphon and the pre-
sence of the safety float inside the siphon is designed to pre-
vent the escape of combustion gases into the environment.
High efficiency mode
The boiler is equipped with an automatic function that is ac-
tivated at the first power supply or after 60 days of non-use
(electrically powered boiler). In this mode the boiler, for 60
minutes, limits the heating power to a minimum and the maxi-
mum DHW temperature to 55°C. Activating the chimney swe-
ep temporarily disables this function.
During execution, the water pressure icon flashes and the di-
splay shows:
