•
set ON/OFF switch in ON position (see fig.1), after a few seconds the pump will come into operation;
•
once the boiler is working, if any noises are heard in the system, repeat the above air purging procedures until there is no air left in the
system;
•
check there are no obstructions in the exhaust duct;
•
check the pressure in the system: if this has gone down, comes on restore pressure
;
•
close the filling tap R (see fig. 2) once this operation is completed
;
Filling the system
After making sure the gas cock is closed, fill the heating system as follows;
•
fill the system until a pressure of 1.5 bar has been reached (light no. 11 ON; see fig. 1
pag. 9) and then close the tap on the filling loop;
•
make sure the cap on the auto air vent valve is slightly loose to allow air to escape from
the system;
•
undo the cap on the circulation pump to eliminate any eventual air locks; it is a good
idea to purge all radiators of air at this point too;
•
before starting up the boiler the water pressure must be checked again; if this is seen to
be below 0.5 bar, bring it back up to 1.5 bar (light no. 11 ON; see fig. 1 pag. 9)
and
close the tap on the filling loop
•
set ON/OFF switch in ON position (fig.1 page 9), after a few seconds the pump will
come into operation;
•
once the boiler is working, if any noises are heard in the system, repeat the above air
purging procedures until there is no air left in the system;
•
check there are no obstructions in the exhaust duct;
•
check the pressure in the system: if this has gone down, comes on restore pressure
;
•
close the tap on the filling loop once this operation is completed
;
Starting up the boiler
•
open the gas cock;
•
turn on the boiler;
•
push Pad 5 and select the SUMMER only – WINTER only or SUMMER and WINTER
mode- Led 8-9 ON confirm the selection;
the automatic ignition system will turn the burner on
It may be necessary to repeat the
procedure a few times to purge air from the pipes. Set the ON/OFF switch 1 (see fig.1) to OFF and then ON position and try the
ignition procedure once again. If the boiler does not start, reset boiler and Set the ON/OFF switch 1 to OFF and then ON position.
IMPORTANT
should the boiler fail to ignite
wait 3 minutes
before
a new ignition procedure.
In case of water deficiency the display shows code 04 intermittent and the Led 8 is ON. To restore water pressure open the tap on the filling
loop and fill the system, when led 10 (1.5 bar pressure) is ON, close the tap.
•
set ON/OFF switch in OFF position (fig.1 page 9), insert a gauge into the pressure point no.4 (fig.2 page 11). Turn ON the boiler and
check the minimum and maximum gas pressure setting in accordance with values stated on the gas data plate (to check maximum gas
pressure value, turn ON a hot water tap and check that the maximum pressure is equal to that stated on the gas data plate; to check the
minimum gas pressure, close the hot water tap, and select WINTER mode, the pressure gauge will show the minimum gas pressure
value for 10 seconds. If the pressure values are not the same as those stated on the gas data plate, calibrate pressure again
•
once the calibration procedure has been completed, unplug the mains lead or turn off the mains switch, close the gas cock and remove
the gauge from the pressure point; tighten the screw making sure there are no gas leaks;
•
after carrying out this operation, return the panel to its correct position and put the front casing back.
CHECK
the maximum heating power.
For procedure regarding regulation of the heating system thermal capacity
see «BOILER ADJUSTMENTS».
EMPTYING THE CENTRAL HEATING SYSTEM
Whenever it is necessary to empty the system, proceed as follows:
•
set ON/OFF switch in OFF position (fig.1 page 9);
•
wait for the boiler to cool down;
turn the system drain tap
RS
(see fig. 3) and use a container to collect the water that runs out;
EMPTYING THE DOMESTIC HOT WATER SYSTEM
Whenever there is danger of freezing, the hot water system should be emptied in the following way:
•
shut off the water at the mains;
•
open all hot and cold water taps;
•
empty from the lowest point (where possible).
WARNING
Please ensure that the boiler in commissioned in line with all BENCHMARK BOOKLET REQUIREMENTS. Failure to do this may in validate
the guarentee.
