Does natural gas have a shut-off valve?
Houses with natural gas have a main shutoff valve (Fig. A) located just before the gas meter. This valve, often called the street-side valve, is normally a rectangular nub (Photo 1). When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing.
What is a natural gas shut-off valve?
Natural Gas Shut-off Valves For safety, a shut-off valve should be installed at every natural gas appliance.

Some valves require a wrench to turn them.
Can I use copper tubing for natural gas in MN?

What is the best pipe for natural gas?
CSST tubing, or corrugated stainless steel tubing, is good for installing gas appliances. These corrugated pipes can bend around corners reducing the number of joints and fittings. Easier to work with than steel pipe and weighs a lot less.
Are brass fittings OK for natural gas?
Piping materials Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper.

How are gas valves used in a heating system?
More About Gas Valves & Controls. Gas valves are used to regulate natural gas or liquid propane in heating systems. Gas valves vary in capacity (cubic ft of gas), inlet/outlet size, and type (standing pilot, slow opening, and step opening). Gas valves and controls must match the heating system’s fuel type.
What kind of gas valves does Honeywell use?
Diaphragm Gas Valves Honeywell diaphragm valves are the valve and actuator in single body construction for use on boilers, unit heaters, duct furnaces, make-up air and rooftop heaters
What kind of valve do I need for a propane line?
Install these low-profile valves in low-clearance pipelines for natural gas, propane, and butane. With 45° flared tube fittings, these valves form a tight seal on metal tubing lines for natural gas, propane, and butane.
