PRESSURE REGULATORS
FUNCTIONS
A
Gas Pressure Regulator
is a mechanical device that performs the following two functions:
• Reduces higher incoming gas pressure to a desired lower outgoing gas pressure.
• Maintains a steady, even flow of gas as it leaves the regulator.
The
Appliance Pressure Regulator
is used to further reduce the gas pressure to the desired level
for the particular application (see Figure 2-1). This is the final stage of gas regulation. It controls
gas at a lower pressure and flow rate.

It is recommended that the pressure regulator be connected to a manual gas shutoff valve, via a
flexible line (depending on local codes), so that it will be easy to shut off the gas supply to the range
before servicing it (see Figure 2-2).
