Loss of system water pressure.
Explain that the dial on the control panel front indicates
the central heating system pressure and that if the normal
COLD pressure of the system is seen to decrease over a
period of time then a water leak is indicated. Explain the
re-pressurising procedure and if unable to re-pressurise
or if the pressure continues to drop a registered local
heating installer should be consulted.
8.
Explain boiler restart procedure.
9.
After installation and commissioning please complete the
Commissioning Checklist before handover to the customer.
IMPORTANT
10.
A comprehensive service should be carried out annually.
Stress the importance of regular servicing by a Gas Safe
Registered Engineer.
11.
Inform the householder of the guarantee/registration
found within the envelope pack and then requirement to
register it to receive the full benefit of the warranty.
1.
Hand the Instructions to the householder and explain his/her
responsibilities under the relevant national regulations.
2.
Explain and demonstrate the lighting and shutting down
procedures.
3.
The operation of the boiler and the use and adjustment
of all system controls should be fully explained to the
householder, to ensure the greatest possible fuel economy
consistent with the householder requirements of both
heating and hot water consumption. Advise the user of the
precautions necessary to prevent damage to the system
and to the building. In the event of the system remaining
inoperative during frosty conditions.
4.
Explain the function and the use of the boiler heating and
domestic hot water controls. Explain that due to system
variations and seasonal temperature fluctuations DHW
flow rates/temperature rise will vary, requiring adjustment
at the draw off tap. It is therefore necessary to draw the
user’s attention to the section in the Users Instructions titled
“Control of Water Temperature” and the following statement.
“Additionally, the temperatures can be controlled by
the user via the draw-off tap: the lower the rate the
higher the temperature and vice versa.”
5.
Explain the function of the boiler fault mode. Emphasise that
if a fault is indicated refer to “Fault Codes” in the User Guide.
6.
Explain and demonstrate the function of timers and
temperature controls, radiator valves etc. for the economic
use of the system.
After completing the installation and commissioning of the system the installer should hand over to the householder by
the following actions:

Refer to Section
2.29
2.31 HANDING OVER
To access Installer Mode, press the “MODE” and “RESTART”
buttons together for more than 5s.
1. The last 3 faults will be shown. See Frame 4.1 for Fault
Code descriptions.
2. “
PH
” will be shown.
To change the preheat setting press Restart, press Mode,
then press Restart again, otherwise press Mode.
Timed Preheat Function
If Preheat is switched On, then preheating will occur at the
same times that hot water demands occurred on the previous
day.
E.g. If you have a shower at 6am on a Monday, then the
boiler will automatically preheat the water for your shower for
6am on a Tuesday.
Consequently the function becomes active 24 hours after it is
switched on. This function is designed to maximise comfort,
whilst minimising energy consumption.
3. “

” will be shown.
To run the burner at maximum rate press “RESTART”,
otherwise press “MODE”.
4. “
SL
” will be shown.
To run the burner at minimum rate press “RESTART”,
otherwise press “MODE”. Note that if the return temperature
is less than 40°C then the burner will run at maximum rate
for 30s before ramping down to minimum rate over 60s and
then running at minimum rate for 10 minutes. If the return
temperature is more than 40°C the burner will immediately
ramp down to minimum rate over 60s and then run at
minimum rate for 10 minutes.
5. “
UF
” will be shown.
To activate the Venting function press “RESTART”, otherwise
press “MODE”. The Venting function runs for 5 minutes
before automatically returning to normal operation. The
diverter valve moves between CH and DHW every 30s. The
pump alternates between being on for 50s and then off for
10s.
6. “

To move the diverter valve to mid-position for replacement
press “RESTART”, otherwise press “MODE”.

To set the minimum CH pump speed to 100% press
“RESTART”, otherwise press “MODE”.
8. “
