Table. 9 - Typology
If the boiler is to be connected
DIVACONDENS F D
to a collective flue or to a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical personnel in conformity with the current regulations and be suitable
for sealed chamber units equipped with fan.
4. SERVICE AND MAINTENANCE
Important
B
All adjustment, conversion, commissioning and maintenance operations
described below must only be carried out by Qualified Personnel (meet-
ing the professional technical requirements of current regulations) such
as the personnel of the Local After-Sales Technical Service.
FERROLI declines any liability for damage and/or injury caused by un-
qualified and unauthorized persons tampering with the unit.
4.1 Adjustments
Gas conversion
B
ALL COMPONENTS DAMAGED DURING CONVERSION OPERATIONS
MUST BE REPLACED
.
The unit can operate on natural gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the data plate. Whenever a gas dif-
ferent from that for which the unit is arranged has to be used, the special conversion kit
will be required, proceeding as follows:
1.
Disconnect the boiler power supply and close the gas cock.
2.
Replace the nozzles at the main burner, fitting the nozzles specified in the technical
data table in cap. 5, according to the type of gas used
3.
Switch the boiler power on and open the gas cock.
4.
Modify the parameter for the type of gas:
•
put the boiler in standby mode
•
press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds: the display shows
“
b01
“ flashing.
•
press the DHW buttons details 1 and 2 - fig. 1 to set the parameter
00
(for nat-
ural gas operation) or
01
(for LPG operation).
•
press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds.
•
the boiler will return to standby mode
5.
Adjust the minimum and maximum pressures at the burner (ref. relevant para-
graph), setting the values given in the technical data table for the type of gas used
6.
Apply the sticker contained in the conversion kit, near the data plate as proof of the
conversion.
Activation of Auto-setting function for gas valve calibration
THIS PROCEDURE MUST ONLY BE CARRIED OUT IN THE FOLLOWING CASES:
GAS VALVE REPLACEMENT, CARD REPLACEMENT, CONVERSION FOR GAS
CHANGE
.
The B&P Gas Valve (with integrated modulating operator) does not provide for mechan-
ical calibration: the minimum and maximum power adjustments are therefore electroni-
cally done via two parameters:
Gas valve pre-calibration
1.
Connect a pressure gauge to monitor the gas valve outlet pressure.
2.
Enable the
Auto-setting
function (Parameter b12=1).
3.
Activate the calibration procedure by pressing the h button and Eco/Comfort
button together for 5 seconds. The message "Au-to" immediately appears (in two
successive flashes) and the burner is lit. Within 8 seconds (natural gas and LPG)
the boiler finds the ignition point. The ignition point, absolute minimum current Offset
(Parameter q01) and absolute maximum current Offset (Parameter q02) values are
stored by the card.
Gas valve calibration
1.
The display will show "q02" flashing; the modulation current is forced to the pre-cal-
ibration value of the absolute maximum current Offset parameter (Parameter q02).
2.
Press the DHW buttons to adjust the parameter "q02" until the maximum nominal
pressure minus 1mbar is reached on the pressure gauge. Wait 10 seconds for the
pressure to stabilise.
3.
Press the
DHW “+”
button to set the parameter
“q02”
until the maximum nominal pres-
sure is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
4.
If the pressure read on the pressure gauge is different from the maximum nominal
pressure, proceed in increments of 1 or 2 units of the parameter "q02" by pressing the
DHW “+”
button: after each change, wait 10 seconds for the pressure to stabilise.
5.
When the pressure read on the pressure gauge is equal to the maximum nominal
pressure (the newly calibrated value of the parameter "q02" is automatically saved),
press the
heating “–”
button: the display will show "q01" flashing; the modulation
current is forced to the pre-calibration value of the absolute minimum current Offset
parameter (Parameter q01).
6.
Press the DHW buttons to adjust the parameter "q01" until the minimum nominal
pressure plus 0.5mbar is reached on the pressure gauge. Wait 10 seconds for the
pressure to stabilise.
7.
Press the
DHW “-”
button to adjust the parameter "q01" until the minimum nominal pres-
sure is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
8.
If the pressure read on the pressure gauge is different from the minimum nominal
pressure, proceed in decrements of 1 or 2 units of the parameter
“q01”
by pressing
the
DHW “-”
button: after each change, wait 10 seconds for the pressure to stabilise.
9.
When the pressure read on the pressure gauge is equal to the minimum nominal
pressure (the newly calibrated value of the parameter "q01" is automatically saved.),
recheck both adjustments by pressing the heating buttons and correct them if nec-
essary by repeating the procedure described above.
10. The calibration procedure ends automatically after 15 minutes or by pressing the
heating “+”
and Eco/Comfort buttons together for 5 seconds.
