7. Draw attention to the timer Users Instructions and hand them
to the householder.
8. Loss of system water pressure
Explain that the dial underneath the boiler 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.
9. Explain Boiler reset procedure.
10. After installation and commissioning please complete
the
Commissioning Checklist before
handover to the customer. For IE, its is necessary to

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 household 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 users attention to the
section in the Users Instructions titled “Control of Water
Temperature” and the following statement:
“additionally, the temperature 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 time 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:
