13 - START-UP
13.6 - Ignition
1.- Turn on the manual gas shut-off valve;
2.- Connect the appliance to the electricity and set the general
switch to ON (detail “T” in Figure 14-1);
3.- The appliance only switches on when the set temperature
is higher than the current supply temperature. Adjust the
desired temperature for the supply using the
and
keys;
4.- If the display shows a low water flow rate error (see section
14.10.2), bleed the air again.
13.7 - Check gas supply pressure and
make any necessary adjustment
The gas supply pressure must match that shown in the table
in section 16. To check it do the following:
1.- Turn off the appliance and the manual gas shut off valve;
2.- Access the appliance internal parts by following the
procedure described in section 15.2;
3.- Loosen pressure port “D” (see Figure 13-6);
4.- Connect to a manometer with a resolution of at least 0.1
mbar (1 mmH2O). For models from 100 to 140 you can
use any one of the valves;
5.- Turn on the manual gas shut off valve;
6.- Make sure the pressure does not exceed 45 mbar;
7.- position the main switch to ON (part “T” in Figure 14-1)
and generate a heating demand by pressing the
key
until the maximum value. Make sure the room thermostat
is being called and the system is in the conditions to
dissipate the heat generated;
8.- Set parameter
2200
to
HIGH
(in the 60 and 70
models, use parameter
2010
). The burners will now
work at maximum output heat for 20 minutes;
9.- With the appliance at maximum flow rate, make sure
that the gas supply pressure does not drop below the
value shown in Figure 13-8. If the pressure is lower,
do not attempt to adjust the appliance; you must work
upstream to reset proper pressure and gas flow rate.
WARNING !!! Do not touch screws “E” and “F”
in figure 13-10. They are factory set for proper gas flow
rate and supply pressure.
After having made sure the gas pressure is correct:
1.- Bring parameter
2200
back to
OFF
(in the 60 and 70
models, use parameter
2010
).
2.- Turn off the manual gas shut-off valve;
3.- Disconnect the manometer and close pressure plug “D”
again;
4.- Check for and gas leaks from pressure plug “D” (Figure
13-6);
Do not force the screws to close the pressure port in
order to avoid damaging to the gas valve.
WARNING!!! Carry out the gas leak test only with
a leak detection fluid. The use of open flame is absolutely
forbidden.
