nel. Referring to the attached technical data sheet, replace
the main nozzle and adjust the primary air by setting the
referred bush.
Check the diameter of the nozzle, printed on the nozzle,
that has to be replaced is 1/100 mm.
The nozzle is placed on the lower left back side of the
equipment. To replace the nozzle and adjust the primary
air setting, proceed as follows (see the picture here be-
low):
• loose screw A
• move the bush B as indicated on the attached chart
• unfix and take off the nozzle C by using a 13 mm span-
ner
• install the nozzle suitable to the gas type available on
the main (see proper technical data sheet)
• place the bush B at the right distance H (see proper
technical data sheet).
• screw the screw A
Warning!
After the equipment has been set to a different
type of gas:
• place on the equipment place a inerasable sticker with
the new setting data.
• Seal again the adjusted parts.
• Proceed with gas circuit seal test procedure.
• Make a general working test on the whole system.
4.4 CHECK OF THE NOMINAL THERMAL POWER
RATE
The nominal thermal power rate has to be checked by
authorized personnel or by the company in charge on the
basis of the information indicated on this manual.
This check is required at any new installation, transfor-
mation or adjustment to different gas types and after any
maintenance work.
The nominal thermal power rate and the connection pres-
sure values are indicated on the technical data sheet.
Do not remove the parts sealed with red paint.
The required nominal thermal power rate is set by using
the nozzles as indicated on the respective chart of the
technical data sheet and by setting the specific connection
pressure value indicated per gas type.
In case you need a further test to be made on the nominal
thermal power rate, proceed with the volumetric meth-
od by using a counter and a chronometer.
The exact volume that has to pass per time unit is indi-
cated on the respective chart on the technical data sheet.
This value for the connection has to be respected with
a tolerance of ±5%. In case a difference value is found,
check the diameter of the used nozzles and inlet pressure
are correctly set.
4.5 CHECK OF THE SERVICE PIPE PRESSURE
The service pipe pressure is measured, with the equip-
ment turned on, by using a pressure gauge for fluids (e.g.:
a “U” type manometer with resolution 0,1 mbar or an
electronic manometer): make sure the taken pressure
value matches with the value indicated on the respective
chart.
To check the inlet pressure proceed as follows: close the
gas cock installed between the equipment and the gas
main, remove the gas feeding pipe and insert between
the pipe and the oven gas inlet a T fitting; connect on the
free end of the T fitting a manometer suitable to check
the pressure.
In case the taken pressure value is lower than the value
indicated on the ” CHART A”,(more than 0,2 mbar below
indicated value), apply to local gas company.
Warning!
Never tamper the gas solenoid valve parts set and sealed
by the producer.
