13.1 •
All appliances, during final testing in the
factory, are fitted for the type of gas shown
on the sticker next to the data plate. Should
the appliance fitting not correspond to the
family of gases available on location, the
appliance must be converted to adapt to
the type of gas available. If conversion is
necessary, then you must inform Customer
Service and refer to the technical manual.
13.2 •
Commissioning of the appliance to operate
at the rated heat output is dependent on the
inlet pressure and calorific value of the gas
and the correct amount of primary air.
13.3 •
The inlet pressure required for the appliance
to operate with the various types of gas
typically available will be within the limits
indicated in table 6
of the
“Tecnical gas data”
booklet.
The appliance must not be commissioned
if inlet pressure values are outside these
limits
. If pressures differ from those indicated
in Table 6, the gas supply company or
agency should be contacted, or alternatively
the contractor by which the system was
installed in the building.
13.4 •
The lower calorific value of the gas can be
checked with the supply company or agency,
and should comply with the information given
in table 5 of the
“Tecnical gas data”
booklet.
13.5 • MEASURING THE INLET PRESSURE
The inlet pressure is measured using a
manometer connected to the pressure tap (3)
of the gas adjustment valve. To gain access
to the valve, the right-hand side casing panel
has to be removed.
Before connecting the manometer it
is necessary to loosen the screw sealing
the pressure tap (3). You then measure the
pressure with the burner in operation. The
value shown on the manometer must come
within the limits given in table 6
“
of the
“Tecnical gas data”
booklet.
After checking, carefully close the screw (3).
The sealed screws you can see on the valves
must never be tampered with under any
circumstances.
Tampering immediately invalidates
warranty!
