32 HANDING OVER
After completing the installation and commissioning of the
system, the installer should hand over to the householder by
the following actions:
1 Hand the User’s Instructions to the householder and
explain his or her responsibilities under the Gas Safety
(Installation and Use) Regulations 1994 and amendments
1996 or rules in force.
2 Draw attention to the Lighting Instruction label affixed to
the inside of the lower front door.
3 Explain and demonstrate the lighting and shutting down
procedures.
4 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 household requirements of both
heating and hot water consumption.
5 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.
6 If a programmer is fitted, draw attention to the
Programmer Instructions and hand them to the
householder.
7 After installation and commissioning please complete the
Commissioning Checklist before handover to
the customer.
For IE, it is necessary to complete a “Declaration of
Conformity” to indicate compliance to I.S. 813:2002.
8 Stress the importance of regular servicing by a CORGI
registered installer and that a comprehensive service
should be carried out AT LEAST ONCE A YEAR.
In IE, servicing work must be carried out by a competent
person.
Emphasise to the user that the boiler may stop working if the
system pressure is lowered by draining radiators to
decorate behind them. In particular, explain to the user how
the domestic hot water temperature varies with flow rate.
This is especially important when water is drawn off while
the boiler is already running for central heating.
