DANGER!
Note that if the boiler is run with an empty
condensate trap there is a danger that fumes
might escape into the room and cause
poisoning. For this reason, it is important to
ensure that the trap is topped up each time the
unit is cleaned.

12.7 User Controls and Options

The mains/reset switch is used to restart the boiler after
a fault condition has occurred, i.e. ignition failure.
The user display (see section 3.3) allows the user to set
the desired central heating temperature.

12.8 Temperature Display

The boiler shows the operating temperature of the unit.

12.9 Pump Exercise Programme

After a power cut or every 24 hour in frost setting
/summer mode the pump will run for one minute to
prevent it from sticking. This will also occur during
normal operating if there is no demand for more than 24
hours.

12.10 Hand over to user

Instruct and demonstrate the lighting procedure and
advise the user on the safe and efficient operation of the
boiler. Instruct on and demonstrate the operation of any
heating system controls.
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
adequate.
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.
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
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 saver program would not be
operable.
Reminder, leave these instructions including the
'Benchmark' logbook with the user.
