Choosing the Right Regulator(s) for an LP Gas System
Surviving Cold Weather
Winter is coming and although we may want to hope for the best, it's usually better to plan for the worst. In an effort to assist you with your preparation process, we provide items intended to enable you, and your customers, to better survive cold weather.
Regulator freeze-ups occur because there is excessive moisture in propane, or when the flow of propane is restricted due to pigtails that are improperly formed or kinked. Temperature may also be a contributing factor… freeze-ups can even occur at temperatures above 32° Fahrenheit.
Propane should be checked for moisture content prior to delivery to consumers.
Install RegO 5 PSI First Stage Regulators (SR9 type) when the temperature drops to a certain point, there won’t be enough pressure for a 10 PSI regulator to operate.
Example: 1,000,000 BTU load at 5 PSI
1,000,000 x 1.120 = 1,120,000 BTUs… then use chart based on 1,120,000
Use 3/8” tube, heavy-duty RegO Hog Tails. They’re available in a variety of connections, lengths and styles (straight or preformed). They have individually soldered connections to the copper tubing and are tested prior to shipment.
Notes:
1. RegO recommends that a new pigtail or hog tail be installed with every new or replacement regulator.
2. Care should always be taken in selecting the proper pigtail for each application.
A Viatran AT-1000 Freeze Valve indicates the presence, or absence, of moisture in liquefied propane gas (LPG).
The use of this valve, and test method, provides a relative measure of the tendency of liquefied petroleum gasses containing moisture to freeze in pressure-reducing regulators which may interrupt the normal flow of gas.
Any container suspected of having excessive moisture should be treated with the proper amount of methanol. A gravity-fed Methanol Injector, with 1-1/4” ACME connector (female), provides a fast and efficient method to inject methanol into stationary ASME containers to help prevent condensation from freezing in the propane system.

Choosing the Right Regulator(s) for an LP Gas System
Selecting the correct regulator for an LP Gas system is essential for ensuring safety, efficiency, and optimal performance. Whether you’re installing a residential system or managing a commercial application, understanding the types of regulators and their specific uses will enable you to make the best choice for your systems. The guide below is intended to assist you with the process of selecting the right regulator for various applications.
The Important Role of Regulators
Regulators play a vital role in both safety and the efficient use of propane systems by consistently controlling pressure of propane gas flowing from a tank to appliances. A properly functioning regulator maintains stable pressure and prevents fluctuations which could otherwise lead to inefficient appliance performance, energy waste, or, in extreme cases, hazardous conditions such as leaks or fires.
Types of Regulators
Different applications require specific types of regulators. Here are the most common:
Typically used in two-stage systems. Reduces tank pressure to an intermediate level for further regulation.
Common for residential systems. Reduces pressure from a 1st stage regulator to a level appropriate for appliances.
Ideal for smaller installations. Combines the functionality of both 1st and 2nd stage regulators into one unit.
Often used with burners, fryers, or equipment requiring high BTU output. Deliver high-pressure gas for industrial or specialized applications.
Designed for systems with multiple tanks. Automatically switches to a reserve cylinder when the primary cylinder is empty.
Ideal for installations with limited space. Reliable pressure control in a small, streamlined package.
Assess Your System’s Requirements
Selecting the correct regulator depends upon the unique demands of a system:
BTU Load
Calculate the total BTU load of all appliances (and any potential future
additions) to ensure that the regulator(s) are adequate for the demand.
Inlet and Outlet Pressure
Verify that the regulator pressure setting matches the system requirements.
Distance from the Tank
Longer distances may require greater inlet pressure or specific types of regulators
to maintain performance.
Environmental Factors
Consider the operating environment, such as extreme temperatures or exposure
to moisture, which can impact regulator performance.
Prioritize Safety and Compliance
Ensure the regulator complies with all relevant safety standards and certifications, such as those established by NFPA (National Fire Protection Association), and your local authority having jurisdiction (e.g. Fire Marshal). Compliance ensures that the regulator is manufactured and tested to safely withstand various operational stresses. Additionally, you should regularly inspect and maintain regulators to avoid potential leaks, clogs, or malfunctions. This includes checking for wear & tear on components, ensuring proper connections, and replacing components (as needed). A proactive approach to maintenance can prevent system failures and extend the life of your equipment, ultimately contributing to safer and more reliable operation.
