MEASURING GAS PRESSURE

Gas pressure is measured in Inches of Water Column Pressure (WCP). It takes 28" WCP to equal one pound per-square-inch (PSI).

In most locations, natural gas pressure entering the home is regulated to 7 inches water column. L.P. gas is regulated between 10 and 12 inches water column. The appliance regulator reduces the incoming pressure to the required amount for the appliance. The model/serial plate on the gas range (see Figure 2-8) provides information about the proper water column pressure. Whirlpool ranges operate on 4 inches water column on natural gas, and 10 inches WCP on L.P.

it becomes necessary to measure these pressures, two instruments are available: a manometer, and a magnehelic gauge.

When it becomes necessary to measure these pressures, there are two instruments available that you can use: a manometer and a magnehelic gauge.

A manometer is basically a U-shaped tube with a scale, marked in inches of water column. To prepare and use the manometer, use the following steps:

1.Check the appliance model/serial plate and note the gas pressure rating.

2.Turn off the gas pressure to the range.

3.Prepare the manometer by filling the U-shaped tube with water so that both sides of the tube fill to the zero point (see Figure 2-9). NOTE: Use a little food coloring in the water to help make reading the meter easier.

4.Connect the tubing that is supplied with the manometer over one end of the manometer.

5.Remove a burner from the appliance and place the free end of the tubing over the burner orifice.

6.Turn on the gas supply to the range.

7.Turn on the gas valve to the orifice being tested and light at least one other burner to serve as a load.
