b
Panel cleaning must be carried out only with soapy
water.
Cleaning the siphon
- Disconnect the tubes (
A
) and (
B
), remove the clip (C) and
remove the siphon.
- Unscrew the bottom and top caps, then remove the float.
- Clean the parts of the siphon from any solid residues.
b
Do not remove the syphon float or seal as these items
are integral in preventing the possibility of flue gases
escaping to atmosphere if/when the syphon is devoid of
any condensate fluid.
b
Once the operations have been completed, reassem-
ble the components by operating in the reverse order to
what is described, checking the floating seal and replace
it if necessary. If replacing the float gasket, make sure it
is correctly positioned in its seat (see figure in section).
b
At the end of the cleaning sequence, fill the siphon with
water before restarting the boiler as follows:
- slowly open the de-aeration valve (7 - fig. 3) and leave
it open until the amount of water contained in the
siphon reaches the maximum level
- close the de-aeration valve (7 - fig. 3)
- check that the condensate siphon connection is tight
- check that the system pressure has not dropped
below 1 bar. If necessary, fill the system.
CHECK THAT THE CONDENSATE DRAIN OUTLET
SIPHON CONTAINS WATER, IF IT WAS NOT FILLED
PROCEED AS DESCRIBED ABOVE.
b
At the end of the siphon maintenance operations, it is
recommended to bring the boiler to condensing mode
for a few minutes and to check for leaks from the entire
condensate evacuation line.

Cleaning the air filter

- Unscrew the fixing screw

and remove the air filter.
- Blow compressed air on the filter to remove any impurities.
- In case of persistent dirt wash with water.
Maintenance of the combustion control system
Maintenance electrode
The detection electrode/ionization sensor has an important
function in the boiler ignition phase and in the maintenance of
optimal combustion; in this context, in the event of replacement,
it is necessary to
always ensure
that it is correctly positioned
and to strictly observe the reference shown in the figure.

ionisation sensor

electrode
a
Do not clean the electrode with sandpaper or any other
abrasive material.
b
The ‘Iono’ electrode will degrade over a period of
time and continued usage; it is therefore strongly
recommended that it be replaced after 5-years of use; in
order to ensure continued performance and efficiency,
and avoid appliance malfunction
.
6.20 FINAL CHECKS
• ENSURE THE APPLIANCE FLUE SYSTEM IS FITTED
CORRECTLY AND IS PROPERLY SECURED.
• ENSURE ALL PIPE WORK IS RE-CHECKED FOR
TIGHTNESS.
• COMPLETE BENCHMARK CHECKLIST.
FOR UK ONLY
Complete details of the boiler, controls, installation and
commissioning in the Benchmark checklist at the back of this
book. It is important that the Benchmark checklist is correctly
completed and handed to the user. Failure to install and
commission the appliance to the manufacturers instructions
will invalidate the warranty.
6.21 INSTRUCTING THE USER
Hand over all documentation supplied with this appliance –
including these instructions – and explain the importance of
keeping them in a safe place. Explain to the user how to isolate
the appliance from the gas, water and electricity supplies and
the locations of all drain points. Show the user how to operate
the appliance and any associated controls correctly. Show the
user the location of the filling valve and how to top-up the system
pressure correctly and show the location of all manual air
release points. Explain to the user how to turn off the appliance
for both long and short periods and advise on the necessary
precautions to prevent frost damage.
Explain to the user that for continued safe and efficient operation,
the appliance must be serviced annually by a competent person.
IMPORTANT
To validate the appliance warranty, it’s necessary to register
the appliance details with us. The warranty can be registered
in several ways:
• online at: vokera.co.uk
• for UK residents by calling: 0800 479 0751
