Biasi UK Ltd support the Benchmark initi-
ative. The Benchmark Checklist is located
at the back of this manual and should be
completed by the Installing/Commission-
ing Engineer and handed over to the User
for future reference by other visiting En-
gineers.
Also included is the Service Interval Re-
cord card that should be completed by
the Service Engineer following the annu-
al service maintenance of the boiler and
system.
All Gas Safe Registered Installers carry a
Gas Safe ID card, and have a registration
number. Both should be recorded in your
Benchmark Checklist. You can check your
Installer is registered by calling Gas Safe
direct on 0800 408 5500, or go on line at
www.GasSafeRegister.co.uk.
In order to guarantee safety and correct op-
eration, it is essential that all the tests are
carried out by a competent and responsible
service engineer before lighting up the boiler.
The tests are described in the installation in-
structions in section 7 commissioning.
Ensure that the c.h. circuit is regularly filled
with water (even if the boiler is only used for
d.h.w. supply).
In order to activate, press keys 14 and 16 to-
gether to access the "INFO" menu. The dis-
play displays the value "d0" that alternates
with the pressure value "13" (1,3 bar). The
number indicating the pressure, is displayed
without decimal points while the letter indi-
cates the unit of measure (bar) Fig. 2.2.
If the pressure reading on the pressure
gauge is below that shown in Fig. 2.2, then
the system will require topping up. A filling

If you are in any doubt regarding this pro-
cedure you are advised to contact your
Installer or an Approved Engineer.
This appliance is provided with a built in anti-
freeze system that operates the boiler when
the temperature is below 5 °C.
Therefore, when the boiler is not lit or used in
cold weather, with consequent risk of freez-
ing do not switch off the boiler at the fused
spur isolation switch or close the gas inlet
cock.
When you do not expect to use the boiler for
a long period and the boiler is not to be used
for frost protection then follow the instructions
given in section "Extinguishing" to page 17.
