properly cleaned. Even the simple contact with your fingers can
leave a slight amount of grease that is enough to compromise the
operation of the photocell. The photocell does not "detect" daylight
or the light from a common lamp. Its sensitivity can be tested
using a flame (lighter, candle). To ensure a proper operation,
the cell voltage value must be sufficiently stable and not go
below the minimum value required for the specific equipment.
The check is performed between the terminals of the electric
panel as shown in the wiring diagram.
• When the burner is working at its "minimum" output, adjust the
air and gas in the proper quantities to ensure a good combustion.
• After adjusting the air for the operation at the "minimum" output,
increase the power and proceed to define the operating curve as
described in the equipment manual. It is recommended to check
combustion using the specific instrument at all intermediate
points on the modulation curve.
• Once the regulation of air and gas is complete, check the
amount of gas actually delivered by reading the meter. Do not
permit the burner to operate if the combusted thermal flow rate
exceeds the maximum one permitted for the boiler, to prevent
it from being damaged. Upon defining the modulation curve, it
is possible to have an approximate estimate of the thermal flow
rate delivered at the intermediate points be measuring the gas
pressure in the combustion head. Connect a pressure gauge
with scale appropriate to the port (G) (see picture) and measure
the gas pressure. From diagram (0002922850 стр. 17) obtain
the thermal flow rate delivered, depending on the value of the
pressure measured without the back pressure in the furnace.
This method permits only an approximate estimate of
the combusted thermal flow rate delivered, for a precise
measuring, refer to gas meter.
Example:
• Burner TBML 800
• Pressure measured on port G: Ptc=48 mbar
• Back pressure measured in the furnace: Pcc=10 mbar
• Head pressure value without the back pressure in the furnace:
P=48-10=38 mbar
• From the diagram, in correspondence of pressure P=38 mbar, a
combusted thermal flow rate of about 7300 kW can be inferred.
