maintained by a competent person and in accordance with the
latest regulations.

1.4 APPLIANCE COMMISSIONING CHECKLIST
(UK only)
A checklist section can be found at the rear of the appliance
installation booklet. This important document must be com-
pleted during the installation/commissioning of your boiler. All
GAS SAFE registered installers carry a GAS SAFE ID card,
and have a registration number. These details should be re-
corded in the Benchmark commissioning checklist section
within the installation booklet. You can check your installers
details by calling GAS SAFE direct on 08004085500. Failure
to install and commission the appliance in accordance with
the manufacturers instructions will invalidate the warranty.
This does not affect your statutory rights.
1.5 HOW DOES IT WORK?
Your
Unica
boiler supplies heated water to your radiators and
hot water to your hot water taps. The central heating is con-
trolled via a time clock and any thermostats that your installer
may have
fi
tted. The boiler will light when it receives a request
from the time clock via any thermostat that may be installed, or
whenever a hot water outlet (tap) is opened. Your
Unica
boiler
lights electronically and does not have a pilot light.
In the unlikely event of a fault developing with your boiler, the
supply of gas to the burner will be terminated automatically.
Dear Customer
Your Vokèra
Unica
boiler has been designed to meet and exceed the very latest standards in gas central heating technology,
and if cared for, will give years of reliable use and ef
fi
ciency.

INTRODUCTION
1.6 DIMENSIONS
1.7 CLEARANCES REQUIRED
1.8 FROST PROTECTION SYSTEM
The
Unica
is equipped with a built-in frost protection system,
this enables the boiler to over-ride the time controls – even if
switched off – and operate the burner and/or pump, should
the temperature drop below 5
0
C for the main and for the DHW
line. In particular the burner will be in ON status until the main
temperature reaches 35°C for CH appliance and 55°C for
DHW appliance.
Please note that the frost protection system
is designed to protect the appliance only, should frost protec-
tion be required for the heating system, additional controls
may be required.
NOTE
The frost protection system is reliant on the appliance having a
permanent electrical supply, and being in a non-fault condition.
1.9 APPLIANCE STATUS INDICATORS
Your boiler is equipped with a large LCD display that indicates
the appliance operating status.
