Adjustment and Maintenance
WARNING: Hereby described operation can be performed by qualified technicians only.
When regulation/measuring is over, remember to tighten pressure tapping point screws and
ALWAYS check for gas leaks!
Before switching on the boiler, make sure that the circulating pump is not blocked due to
inactivity: in the middle of the cap there is a hole (should there be a plug, remove it) that gives
access to the rotor shaft; push and turn it using a suitable tool , usually a screwdriver.
During the commissioning of the new boiler , it is necessary to run the burner for 30 minutes
before checking the combustion because, in that period of time, any residual fabrication va-
pours could cause false results in the combustion products analysis.
Remark:
during the first 10 minutes of electrical power supply, the re-ignition delay in heating mode
might be nil.
•
The ignition electronics does several ignition attempts, to avoid blocking the boiler when the ignition
fails sporadically.
•
When the gas supply pipe is filled with air (e.g. in case of new installation) it may be necessary to repeat
the ignition cycle several times.
• The boiler is factory regulated and tested. Anyway it’s advisable, during the commissioning, to check
that the regulation is correct.
First starting up
The first ignition operations consist in verifying the correct installation and functioning, and in the even-
tual regulations which are necessary:
f verify that the data of the plate correspond to those of the net supply (electrical, water, gas);
f
verify the absence of the gas leakages from the connections upwards the boiler;
f verify the proper realization and the efficiency of all the boiler connections (water, gas, heating sys-
tem and electrical system);
f
verify the presence of the permanent air/ventilation outlets, correctly dimensioned and working, as
foreseen by the National and Local laws depending on the appliances installed;
f
verify that the evacuation flue duct corresponds to the National and Local laws and that is in good
and efficient conditions;
f verify that the passage of the air burning and the evacuations of the flues will be made correctly ac-
cordingly to National and Local laws in force;
f
verify that the conditions for the air ventilation are granted, in case of a boiler placed inside a piece
of furniture;
f check the inlet gas pressure and flow (see "Inlet gas check" on page 26);
f check the burner pressure at maximum and minimum power input and gas valve adjustment (see
"Max and Min pressure adjustment" on page 26);
