A nameplate identifies and displays a product's name. Nameplates are usually shaped as rectangles but are also seen in other shapes. Nameplates primarily serve an informative function or a commercial role (as in a restaurant equipment, where nameplates are mounted on products to identify the brand).
Even though propane and natural gas are both fossil fuels that burn similarly, you need to convert your appliances when you make the switch. Because they have different densities and amounts of energy, you must switch out the valves and switches to properly control the flow when switching from one to the other. Using a conversion kit provided by the equipment manufacturer is the simplest and safest approach.
Most, but not all, appliances can be converted from natural gas to propane. The biggest sticking point is that natural gas is kept at a lower pressure, and some appliances can't handle the higher pressure of propane even with adjustments.
It is important to consult a professional when considering making the switch from natural gas to propane as the work involved is highly technical and can be dangerous if the person doing the work does not have the required experience.
NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientations, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, & grounding system. The 5-15P and 5-20P and the 5-15R and 5-20R are by far the most common electrical plug and receptacle combinations in North America.
A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe.
American National Standard Pipe Thread standards, often called National Pipe Thread ("NPT") standards for short, are U.S. national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes including rigidity, pressure-tight sealing, or both. The various types are each named with a symbol and a full name; examples of the symbols include NPT, NPS, NPTF, NPSC, and others.
Manufacturers, regulators and consumers look to NSF International for the development of public health standards and certification programs that help protect the world’s food, water, consumer products and environment. NSF's mission is to protect and improve global human health. As an independent, accredited organization, their standards group facilitates the development of standards, and the service groups test and certify products and systems including all sorts of restaurant equipment and accessories. They also provide auditing and risk management solutions for public health and the environment.
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.
An acorn nut, also called a crown hex nut, blind nut, cap nut, domed cap nut, or dome nut, is a nut that has a domed end on one side. When used together with a threaded fastener, the domed end encloses the external thread to protect the thread or to protect nearby objects from contact with the thread.
A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without using tools. A similar fastener with a male thread is called a wing screw.
