For Natural Gas :
Input (MBH)
=
3600 x cu ft
seconds
Example: Natural Gas - Gas flow 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 below, check firing
rate again after setting the combustion following steps in
section 9.10.
