Before installation, check the baffle to be used and make sure the maximum permissible
length has not been exceeded, by means of a simple calculation:
1.
Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2.
Consult the table 5 and identify the losses in m
eq
(equivalent metres) of every com-
ponent, according to the installation position.
3.
Check that the sum total of losses is less than or equal to the maximum permissible
length in table 4.

4. SERVICE AND MAINTENANCE
All adjustment, commissioning and periodical inspection operations described below
must only be carried out by Qualified Personnel (meeting the professional technical re-
quirements prescribed by current regulations).
EUROTERM
declines any liability for damage and/or injury caused by unqualified and
unauthorised persons tampering with the unit.
4.1 Adjustments
Gas conversion
B
Conversion to a different gas from that prearranged in the factory must
be carried out by an authorised technician, using original parts and in
conformity with the regulations in force in the country of installation.
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 dataplate. Whenever a different
gas to that for which the unit is preset has to be used, a conversion kit will be required,
proceeding as follows:
1.
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
2.
Modify the parameter for the type of gas:
•
put the water heater in standby mode
•
press the on/off button detail 7 - fig. 1 for 20 seconds: the display shows
"
b01
"flashing.
•
press the DHW buttons details 1 and 2 - fig. 1 to set parameter
00
(for natural
gas) or
01
(for LPG).
•
press the on/off button detail 7 - fig. 1 for 20 seconds.
•
the water heater will return to standby mode
3.
Adjust the minimum and maximum pressures at the burner (see relevant section ),
setting the values given in the technical data table for the type of gas used
4.
Apply the sticker contained in the conversion kit, near the dataplate as proof of the
conversion.
TEST mode activation
Draw enough domestic hot water to activate the DHW mode.
Press the buttons (details 1 and 2 - fig. 1) together for 5 seconds to activate the
TEST
mode. The water heater will light at the maximum DHW power set as described in the
following section.
The DHW power will be shown on the display.
fig. 9 - TEST mode (DHW power = 100%)
Press the buttons (details 1 and 2 - fig. 1) to increase or decrease the power (Min.=0%,
Max.=100%).
To deactivate the TEST mode, press the buttons (details 1 and 2 - fig. 1) together for 5
seconds.
The TEST mode is automatically disabled in any case after 15 minutes or on stopping of
hot water drawing (if enough hot water was drawn to activate the DHW mode).
Adjustment of pressure at burner
Since this unit has flame modulation, there are two fixed pressure values: the minimum
and maximum, which must be those given in the technical data table according to the
type of gas.
•
Connect a suitable pressure gauge to pressure point
"B"
downstream of the gas valve.
•
Activate the TEST mode (see cap. 4.1).
•
Press the
off button (ref. 7 - fig. 1)
for 2 seconds to access the gas valve Calibration mode.
•
The card goes to the setting “
q02
”; displaying the actually saved value, by pressing
the DHW buttons.
•
If the pressure gauge reading is different from the nominal maximum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter "
q02
" by pressing the
DHW buttons: the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
•
Press the
off button
(ref. 7 - fig. 1).
•
The card goes to the setting “
q01
”; displaying the actually saved value, by pressing
the DHW buttons.
•
If the pressure gauge reading is different from the nominal minimum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter “q01” by pressing the
DHW buttons: the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
•
Recheck both adjustments by pressing the
off button (ref. 7 - fig. 1)
and adjust
them if necessary by repeating the above procedure.
•
Press the
off button
for 2 seconds to return to the TEST mode.
•
Deactivate the TEST mode (see cap. 4.1).
•
Disconnect the pressure gauge.
DHW power adjustment
To adjust the DHW power, switch the boiler to
TEST
mode (see sec. 4.1). Press the
“+”
and
“-”
buttons (details 1 and 2 - fig. 1) to increase or decrease the power (min. = 00 -
max. = 100). Press the
reset
button within 5 seconds and the max. power will remain that
just set. Exit the
TEST
mode (see sec. 4.1).
