Technical description of the burner
4.10 Output supplied
The diagrams allow you to set the power output either using the
number of fan revs or using the pressure downstream of the gas
valve (Fig. 25 on page 27).
Example RX 700 S/PV:
– natural gas G20 PCI 9.45 kWh/Sm
3
– pressure on point 1 = - 12 mbar (2nd chart)
– burnt output corresponds to 600 kW
Going vertically up the 1st diagram, to intersect the dotted line,
you can estimate the value of the number of revs on the left hand
y-axis: in this case 3800 rpm.
For an exact reading of the number of revs there is a kit for inter-
facing with the control box.
the burner can operate with LPG without any additional kit, how-
ever a different regulation of the gas valve is required.
For the G25 the supplied mixer ring for the G25 needs to be ap-
plied as shown in Fig. 12 on page 17.
*For the RX 850 S/PV version, add the mixer ring to the one al-
ready installed on the burner as standard.
