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. 17 on page 23).
Example:
operation with Premix RX 500 S/PV
natural gas G20 PCI 9.45 kWh/Sm
pressure on point 1 = - 5.2 mbar (See 2nd Chart).
The burnt output corresponds to 350 kW.

Going up vertically, in the 1st diagram, until you intersect the dot-
ted line, you can estimate the value of the number of revs on the
left hand y-axis: in this case 4000 rpm
For an exact reading of the number of revs there is a kit for inter-
facing with the control box.
NOTE:
The burner can operate with both with G25 and LPG without any
additional kit, however a regulation of the gas valve is required.
