4.9.3 Gas pressure
The Tab. I is used to calculate manifold pressure taking into ac-
count combustion chamber pressure.
Column 1
Gas manifold pressure measured at test point 1)(Fig. 18), with:
•
Combustion chamber at 0” WC
• Gas ring 2)(Fig. 13) adjusted as indicated in diagram (Fig. 14).
Calculate the approximate output of the burner thus:
– subtract the combustion chamber pressure from the gas pres-
sure measured at test point 1)(Fig. 18).
– Find the nearest pressure value to your result in column 1 of
the table for the burner in question.
– Read off the corresponding output on the left.
Example - RS 28/1:
• Natural gas
• Gas ring 2)(Fig. 13) adjusted as indicated in diagram (Fig. 14).
• Gas pressure at test point 1)(Fig. 18) = 3.69” WC
• Pressure in combustion chamber = 0.79” WC
3.69 - 0.79 = 2.90” WC
A maximum output of 1023 MBtu/hr shown in Tab. I corresponds
to 2.90” WC pressure, column 1.
This value serves as a rough guide, the exact flow rate must be
measured at the gas meter.
