Technical description of the burner
3.7
Output supplied
The diagrams allow you to establish the power output either using
the number of revolutions of the fan or using the pressure meas-
ured at the pressure test point downstream of the gas valve
P2)(Fig. 22 on page 25).
Example RX 700 S/PV:
–
natural gas G20 PCS 1010 Btu/ft
3
–
pressure on point 1 = - 5 “wc (2
nd
chart)
–
burnt output corresponds to 2000 MBtu/h
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 3600 rpm.
For an exact reading of the number of revs there is a kit for inter-
facing with the control box.
NOTE:
The values indicated in the diagrams are indicative for a setting in
principle.
