COMMISSIONING AND OPERATION
4.1 - POSITIONING OF THE
TURBULATORS
The ELLPREX boilers are designed to be used
in an output range to improve the seasonal
efficiency and the possibility to be adopted in
all the heating installations.
The output must be adjusted at the
commissioning stage, according to the system
designer indications and, in any case, within
the operation range for each boiler model
shown on page 6 to 10, by the burner
technician, which will determine the fuel
throughput.
In any case
the turbulators will be placed,
inside the relevant smoke pipes, at a
distance, from the front tube plate, as
shown in fig. 37.
When using the boiler at minimum output the
smoke temperature will not be lower than 160 °C.
In contrary case, before get in touch with our
After Sale Service Dept, ascertain that the
turbulators are in all the smoke pipes.
The commissioning of the burner must be
performed under the responsibility of a
specialized and well trained burner technician,
authorised by the burner manufacturer.
In that occasion a commissioning report has
to be filled out.
