GB: It is a requirement that the “Benchmark” Installation
Commissioning and Service Record is completed and left wth
the user.
IE: it is necessary to complete a “Declaration of Conformity” to
indicate compliance to I.S.813. An example of this is given in
the current edition of I.S.813.
Testing Flue Gases: If any doubt exists that the ue products
are not exhausting correctly, investigate by use of a gas
analyser (FGA).
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 efcient 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
containing a gas appliance in the UK.
The user shall not interfere with or adjust sealed components.
It is the Law that any servicing is carried out by a competent
person.
Advise the user that, like all condensing boilers this appliance
will produce a plume of condensation from the ue terminal in
cool weather. This is due to the high efciency and hence low
ue 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, relling and pressurising MUST be carried out by a
competent person.
Leave these instructions and the ‘Benchmark’ Installation,
Commissioning and Service Record with the user.

12.6 Testing - Heating System
Check that all external controls are calling for heat. The boiler
will re automatically. Fully open all radiator valves, ow
control valve and bypass valve if tted.
Balance the radiators as required and if tted adjust ow
control valve to give the required system differential. Turn off
all radiators that can be shut off by the user and check to see
if less than the maximum differential allowed of 20
0
C can be
achieved across ow and return.
Allow the system to reach maximum temperature then switch
off the boiler by isolating from the electrical supply.
Drain the entire system rapidly whilst hot, using the drain tap
at the lowest part of the system. Fill and vent the system as
described previously in section 12.2
Lock or remove the handle from controls valve, if tted.
