9.14 Check Firing Rate
1.
Measure input, if a gas meter is installed in the
system.
•
Turn off gas to all other appliances.
• Activate some heating zones to dissipate heat.
•
Set boiler on high fire using Chimney Sweep
Function.
• Use ½, 1 or 2 cu ft dial on gas meter. Measure
time required for two or more complete
revolutions. Measure time
for one or more
minutes.
• Calculate input.
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 9-2
check firing rate again after setting the combustion
following steps in section 9.12.
