PRESSURE/FLOW RATE CURVES
They indicate the gas pressure in mbar, (in the various points of the gas ramp) necessary to obtain a determined
flow rate in m3/h. The pressures are measured with the burner functioning and are intended with combustion
chamber at 0 mbar. If the chamber is pressurised, the gas pressure necessary will be that of the diagram plus the
value of that of the chamber.
Pe = Pressure upstream from the valves unit
Pt = Pressure at the combustion head
Pv = Pressure downstream of the ramp
PG = Minimum gas pressure pressure switch

ATTENTION: the Pt-Pv gas pressure outlets have a screw closing pin. Ensure that the Pt - Pv gas outlets
are closed during normal operation.
