PRESSURE REGULATOR

Description

The pressure regulator is a mechanical device that reduces the higher incoming gas pres- sure to a lower outgoing pressure, and main- tains a steady, even flow of gas.

The pressure regulator has one outlet that is connected directly to the gas safety valve. The inlet has a manual shutoff valve so that the gas to the safety valve can be turned off.

The common causes of pressure regulator failure are:

a)Ruptured diaphragm.

b)Broken or weak valve.

c)Accumulated debris around the valve seat.

d)Plugged vent.

The pressure regulator is normally replaced rather than serviced, since it has few replace- able or serviceable parts, and is a relatively inexpensive device.

Test Procedure

WARNING

Electrical Shock Hazard

Disconnect from electrical supply before ser- vicing unit.

Failure to do so could result in death or electrical shock.

Occasionally it may be necessary to adjust the outgoing pressure of the pressure regulator. This is done by adjusting the tension spring of the regulator. A gas pressure test device, called a manometer, is used to monitor the outgoing pressure during adjustment.

To test the pressure regulator, perform the following steps:

1.Attach one side of a manometer to a gas source.

2.Turn on the gas and allow the pressure to move the water column. When the water column has stopped, the gas pressure can be determined from the scale. The reading should be as follows:

Natural Gas:

Minimum pressure = 5-inches WCP Maximum pressure = 14-inches WCP

L.P. Gas:

Minimum pressure = 11-inches WCP Maximum pressure = 14-inches WCP

If the reading is not within the range shown, the pressure regulator is defective and should be replaced.
