Technical description of the burner
4.11 Delivered output (version TC)
The diagrams opposite allow you to set the power output either
using the number of fan revs or using the pressure downstream
of the gas valve (point 1).
Example:
• operation with Premix RX 250 S/PV;
• natural gas G20 NCV 9.45 kWh/Sm3;
• pressure on point 1 = -21 mbar.
The burnt output corresponds to 200 kW.
Going vertically up the 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 4750 rpm. For an exact reading of the number
of revs there is a kit for interfacing with the control box.
NOTE:
A different adjustment of the gas valve is required for LPG
operation.
