REGULATOR VENTS TERMINUS SHALL BE LOCATED AT LEAST 3 FT FROM SOURCES OF IGNITION. IT IS RECOMMENDED THAT
The regulator always should always be fixed on the same level or higher than the cylinder valve.
When using a vent limiting device, the regulator must be mounted in an upright horizontal position only. Vent limiters must be threaded directly into the vent connection of the regulator without intermediate pipe or fittings.
The regulator safety relief valve (vent opening) should be located not less than 5 feet from any potential source of ignition, opening into any sealed combustion chamber appliance, and be not less than 5 feet from any mechanical ventilation air intake. Regulators are mechanical devices and are subject to wear and tear.
410.3 Venting of regulators. Pressure regulators that require a vent shall be vented directly to the outdoors.
Regulators cannot operate without the vent. If the diaphragm were to rupture or perforate, gas would be vented to the exterior of the device. For this reason, regulators installed indoors must be vented to the outdoors or must comply with the exception to this section.
Depending on the angle modification required for the gas intake manifold, the regulator position can be either horizontal or vertical, but never upside down. Preferably, place the regulator on the intake manifold and the gas shut off valve on the gas supply pipe.
You need a line regulator in situations where the pressure of the gas in the main supply line is higher than what your gas appliances can safely handle. This is typically the case in systems where natural gas is distributed at pressures higher than what standard appliances are designed to operate at.
If you have some clearance issues on your home, the utility company or a plumbing contractor may be able to install a vent extension onto the regulator to remedy the issue.
A pressure regulator is normally installed between the meter and the home usually just before a Tee that services the home and an outside hose bib. Normally there is a valve, then a union and the PRV and another union many times built into the PRV itself.
The regulator may be installed in any position: right side up, upside down, vertical piping, diagonal piping, etc., If required the diaphragm case may be rotated 360° in 90° increments.
Q: Where should the pressure regulator be installed? A: On new installations, the pressure regulator is usually installed downstream, (on the house side) of the water meter, near the house.
REGULATOR VENTS TERMINUS SHALL BE LOCATED AT LEAST 3 FT FROM SOURCES OF IGNITION. IT IS RECOMMENDED THAT GAS METERS BE LOCATED 3 FEET FROM SOURCES OF IGNITION; HOWEVER, A MINIMUM DISTANCE OF 18" IS REQUIRED.
Two regulators installed in series can handle the pressure drop with good sensitivity while avoiding the problems encountered when taking large pressure drops across one valve.
If the gas regulator is too large, too much gas can flow into the appliance potentially causing an explosion. If too small, the appliance will not operate efficiently. At worst, it won't operate at all.
To determine how many appliances can run on a 1/2 inch gas line, start by knowing each appliance's BTU rating. A 1/2 inch gas line can handle around 180,000 BTUs per hour. So, add up the BTU ratings of your appliances. Keep this total below 180,000 BTUs to ensure safe operation.
Regulator vent outlets serving natural gas piping shall be located 3 feet (914 mm) horizontally from operable openings above the vent, and 5 feet (1525 mm) horizontally from direct vent appliance intakes and mechanical ventilation air intakes located above the vent, or 1 foot (305 mm) above openings and operable ...
Long Regulator Life Starts With Good Maintenance
In addition to this, the device should be removed from service at least every five years (more frequent in some cases) and returned to the manufacturer, or a competent agent of the manufacturer, to be inspected and/or refurbished as necessary.
Always position the regulator vent so moisture (rain, snow) or foreign particles cannot enter the vent opening. Itron recommends placing the vent downward. Locate the vent away from building eaves, window openings, or building air intakes. Mount the regulator vent above the site's expected snow level when appropriate.
Sometimes the whiffs of gas even come out by design, from a part of the meter known as the pressure regulator. Every meter has one. It is a little-known fact that they burp off gas to relieve pressure.
Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.
In many cases, you can mount the regulator in a location to satisfy ease of installation, adjustment, and appearance. However, in the cases of high power applications, extra low fuel pressure systems, and high-g launches, it's best to mount the regulator as close to the fuel delivery destination as possible.
Figure C - All of the following must be at least 1 metre away from the regulator vent: non-mechanically powered air intake; non-gas appliance exhaust vent; gas dryer vent; potential sources of ignition such as an electrical outlet, electric meter or open flame barbecue; and building openings, including all windows and ...
It depends on your source of gas. If you're feeding your appliances, each from its own little LP tank, then yes, you need a regulator at each location. If you're feeding from a large tank that is distributing to your appliances through piping, you can have a single regulator at the large tank.
