FEATURE
Determine flow of gas through the
gas meter for 2 minutes and multiply
by 30 to get the hourly flow rate.
Turn off all other gas equipment
connected to meter when making
this test.
Manifold pressure should be set to
about 4" W.C. for natural gas. Small
variations in gas flow may be made
by means of the gas pressure regu-
lator adjustment. However, the final
manifold pressure setting should not
vary more than plus oT mlhus 0.3"
from the 4" valve. Any necessary
major changes in the flow should be
made by changing the size of the
burner orifice.
