For Natural Gas :
Input (MBH) =
3600 x cu ft
seconds
Example: Natural Gas - Gas ow from
Meter = 2 cu ft
Measured time = 72 seconds
=
3600 x 2 cu ft
= 100 MBH
72 seconds
For Propane (LP):
Input (MBH) =
9160 x cu ft
seconds
For Metric formulas- See Glossary
2.
Compare measured input to table below. If calculated
input is not in range given in Table 9-2 check ring rate
again after setting the combustion following steps in
section 9.12.
