5.5 Starting the boiler
Once the system has been flushed and filled,
proceed as follows:
•
Check that the exhaust flue is free of
obstructions and correctly connected to the
boiler;
•
Check that all isolation valve are open (CH
circuit and gas)
•
Switch on the power supply to the boiler and
ensure that the system controls are calling
for heat;
•
Switch the boiler on using the ON/OFF
button on the Control Panel (see Section
3.6) and ensure any system controls are
calling for heat. After a few seconds the
circulating pump will start to run;
•
The automatic ignition system will then
attempt to fire the burner. The system will
make 3 attempts and then go to lock-out if
unsuccessful. It may be necessary to repeat
the process a few times in order to eliminate
all the air from the gas supply line. To repeat
the process, wait approximately three
minutes then reset the appliance by
switching the boiler off then on using the
ON/OFF button on the Control Panel;
•
With the boiler ignited, if the system still
emits noises, the above process must be
repeated until all the air has been removed;
•
Check the pressure in the heating circuit
using the pressure gauge (see Section 5.2).
If the pressure has fallen, re-open the filling
loop until the pressure gauge reads 1 bar.
Check that Error Code
H2O
is NOT
displayed on the Control Panel display. On
completion, close the filling loop;
•
Unscrew the plug and insert an analyser in
the exhaust sampling point PF (see Figure
31 – twin pipe flue system depicted) to check
the CO
2
value. The value should correspond
to those in Table 5;
•
If the CO
2
value does not correspond to those in the table, adjust screw V on the venturi (see Figure 31)
clockwise to reduce the CO
2
value or anticlockwise to increase it
.
