4 Gas Regulator Types

Before sizing, understand the regulator’s purpose. There are four primary applications for gas regulators:

1. Appliance regulators control the gas pressure running to an appliance.
2. Line gas regulators control the gas pressure between a service regulator and an appliance regulator on a gas line.
3. Service regulators reduce service line gas pressure to the desired delivery pressure.
4. Pressure regulators reduce, control, and maintain the pressure of a specific portion of a pipe system.

Sizing Cheat Sheet

7 Things You Need for Natural Gas Regulator Sizing

To select a natural gas regulator, here are the seven things you need to know to size your natural gas regulator:

1. Gas type – What type of gas are you regulating? While most customers inquire about natural gas or methane, we also help control propane (LPG).
2. Inlet and outlet pressure – What is the inlet and desired outlet pressure? The units of measure here are either PSIG or WC. If you do not have a pressure gauge, you can always call your gas distributor or inquire about some of our excellent gauges (gages) available.
3. Gas flow – What are the gas load and capacity? What are the minimum and maximum expected capacities in BTU/hr? Or CFH?
   • Flow is typically expressed in CFH (cubic feet per hour or CFM (minute)
   • 1 CF = one cubic foot of gas = 1,000 Btu
   • 1 CFH = one cubic foot of gas per hour = 1,000 Btu/hour
   • 100 CF = 100,000 Btu = 1 Therm
4. Pipe size – What is the pipe size? Regulators are typically available in ½” through 4″.
5. Altitude – Altitude affects regulator sizing. Atmospheric pressure reduces with altitude, so we must ascertain the regulator’s intended elevation. Learn more about the effects of altitude.
6. Location – Is the regulator to be indoors or outdoors? Consider a line pressure regulator with a vent limiter and an overpressure protection device (OPD) if indoors. Learn more about Gas Line Pressure versus Appliance Control regulators.
7. Noise – Is noise an issue? Or vibrations? Humming, buzzing, chugging, and vibrations can occur for various reasons (harmonic instability, hunting, feedback) in a gas system.

Just jumping in here to correct the misinformation.

Standard Natural Gas delivery pressure in the U.S. is generally 7 inches
water column (if your altitude is not too high above sea level) or about 0.25 PSI. Most natural gas appliances require an inlet pressure in the range-ish of, say, 5 to 14 inches water column (less than 0.5 PSI) in order to operate and the gas valve in the appliance then regulates down the small amount necessary for proper combustion.

Anything over about 1/2 PSI will require the customer regulate at some point in front of the appliance. This could be at a manifold in the house, at each appliance, etc....but in no case should the pressure be higher than the appliances maximum inlet pressure rating (as noted in your appliance's owner's manual) at the appliance's gas valve (OR) it may damage the gas valve or the appliance may overfire, which could damage it and will create a safety hazard.

Some residential customers have asked their gas company to supply pressure at more than 1/4 PSI. The majority of these are 2 PSI setups where the customer has CSST piping (or some other issue piping issue) where they want 8 times the normal delivery pressure. These customers (as stated before) must regulate that pressure down somewhere before the appliance.

The only way I would know for sure what pressure the OP is receiving would be to go to his house and install a gauge in his piping and read it. I could look at a picture of his gas pressure regulator at his gas meter and hazard a guess BUT...regulators are typically adjustable to some degree as to outlet pressure, most if not all of them can be equipped with stiffer or lighter springs to change the output pressure range off of what the regulator was originally stamped....and SOME customers in the U.S. don't even have pressure regulators at their meters because the regulation is done by the gas company prior to their service line (low pressure systems).

So...not sure where the guys above got some of the info posted....but thought I'd try to clear it up.
