12 Commissioning

12.8 Instruct the User

● Demonstrate, then instruct the User about the lighting
procedure and heating system controls operation.
● Advise the user on the use and maintenance of any scale
reducer and pass on any relevant instructional documents.
● Advise that to ensure the continued efficient and safe
operation of the boiler it is recommended that it is checked
and serviced at regular intervals. The frequency of servicing
will depend upon the installation conditions and usage, but in
general, once a year should be enough.
● Draw attention, if applicable, to the current issue of the Gas
Safety (Installation and Use) Regulations, Section 35, which
imposes a duty of care on all persons who let out any property
COVER PLATE
containing a gas appliance in the UK.
● The user shall not interfere with or adjust sealed Diagram 12.4
components.
● It is the Law that any servicing is carried out by a
competent person approved at the time by the Health and
Safety Executive.
● Advise the user that, like all condensing boilers this
appliance will produce a plume of condensation from the flue
terminal in cool weather. This is due to the high efficiency and
hence low flue gas temperature of the boiler.
● Advise the user of the precautions necessary to prevent
damage to the system, boiler and the building, in the event of
the heating system being out of use during frost or freezing
conditions.
● Advise the user that the permanent mains electrical supply
SHOULD NOT be switched off, as the built in frost protection
and pump/valve saver program will not operate.
● Advise the User if the mains electricity and gas are to be
turned off for any long periods during severe weather, it is
recommended that the whole system, including the boiler,
should be drained to avoid the risk of freezing.
NOTE: Contact your installation/servicing company as
draining, refilling and pressurising MUST be carried out by a
competent person approved at the time by the Health and
Safety Executive.
● Leave these instructions and the 'Benchmark' service
record with the user.
