Manometers:
The manometer is the best way to accurately determine LP-Gas pressure.
There are two different styles of manometers, a gauge and a U-tube. Gas pressure
is measured in Inches of Water Column. This is the amount of pressure applied
to one side of a U-shaped tube half filled with water. The amount of pressure
needed to raise the column of water 11" represents 11 Inches of Water Column.
WARNING: Do not attempt to adjust the regulator, it is preset at the
factory. If adjustments need to be made it requires special equipment.
Failure to follow these instructions may result in a fire or explosion and
cause severe personal injury or death. Do not operate any LP-Gas
appliance until the LP-Gas pressure is checked and a leak down test is
performed!
