The gas supply rate in U.S. households is on average 300 – 400 CFH supplied through a 1¼ inch gas line. This main supply line has to be distributed through a smaller gas line to the gas range. A typical gas range required 45 CFH of gas supply and thus a ½ inch gas line would provide sufficient amount of gas for it to function properly.
What size natural gas line do I Need?
Size Most natural gas pipes run up to a nominal size of four inches, although you can get pip that’s up to eight inches in diameter. When you see the flow for natural gas in pipes, these don’t refer to copper pipes. The specification for these is going to be different, with different figures.

How much clearance does a gas cooktop need?
Gas ranges require a 6" side wall clearance above the counter height for proper distance from combustible surfaces. Select models may only require a 3" left side wall clearance based upon the burner configuration.
Will increasing pipe size increase gas pressure?
Increasing the pipe size and then reducing it back to the original size sounds crazy. Strictly speaking, the size of the pipe has no effect on the gas pressure.
How far can you run flexible gas line?
Three- or six-foot long and accessible: The flexible connectors can't go through walls, floors or ceilings, nor can they be concealed. The flexible connector length usually is limited to 3 feet except for gas ranges and clothes dryers. For these appliances, 6 feet generally is allowed.
What kind of pipe should I use for natural gas?
PVC. PVC gas pipes work well for underground exterior gas lines because they're durable and resistant to corrosion. PVC pipes are an inexpensive solution, but some locations don't allow them as they can break during the installation process.
How many BTUs can a residential gas meter handle?
A gas meter rated at a maximum continuous capacity of 250 cf/h is capable of providing 250,000 Btu/h maximum. If the continuous meter capacity is greater than demand, your gas meter's size is acceptable.
How do you calculate BTUs?
For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.
What type of pipe is used for natural gas?
The most common materials used to make gas piping are steel, black iron, polyvinyl chloride (PVC), high-density polyethylene (HDPE) and copper. Some utilities prohibit some of these materials, so be sure to check with your local utility to determine what is allowed in your area before you install any.
MAKE SURE YOU HAVE THE CORRECT GAS LINE SIZE FOR YOUR BURNER!
This is such an important part of making sure your fire pit has nice, tall flames! It’s the number one mistake I see people make when shopping fire pits. Watch the video, read the charts and make sure your Fire Pit works great!
EXTREMELY Important Gas Line Sizing Information
The biggest mistake that we see people make is not running a large enough gas line, or choosing a burner that operates at a much higher BTU rating than they’re line, gas meter, or LP tank can supply. The burners operate well even at 70% of the fuel capacity.
How to determine gas line size?
The gas line size will depend on BTU rating of the water heater, the other gas appliances, and where they are installed on each branch from the meter and regulator. There are two methods for determining the required pipe size: the longest length method or the branch length method. See “Gas Pipe System Sizing” for more information.
How much pressure does a gas system need?
A typical residential gas system is a low-pressure system, meaning that the home is supplied with a gas pressure around 7 in. w.c. (inches of water column). The piping must be sized sufficiently enough so that the pressure drop is a half an inch of water column or less, when all the gas appliances are on. This can be the limiting factor ...
How much BTU does a tankless water heater have?
Tankless water heaters can be a great solution to provide hot water; however, most tankless water heaters have a BTU capacity ranging from 140,000 to 200,000 or more, which makes a tankless water heater one of the largest single appliances on a typical gas system. It is necessary to ensure that the system can handle the capacity of the tankless water heater along with all other gas appliances on the system. This guide will address the fundamentals and facts of gas pipe sizing for low-pressure (under 2 psi) natural gas systems using rigid iron pipe.
How to calculate BTUH for natural gas?
Each meter has a capacity in Cubic Feet per Hour (CFH). Locate that number regulator and multiply it by 1,024 (BTUH/CFH) to give you an approximate BTUH capacity for natural gas. The capacity of the meter and regulator must be greater than the total sum of the maximum BTU rating of all the appliances in the home. If the capacity of the system is too small, the gas appliances will not receive the volume of gas required for proper operation.
What is the instrument used to measure gas pressure?
You will need an instrument called a Manometer. This tool allows you to measure the pressure of gas in the system. Manometers are available that measures a specific range of pressure in inches of water column or pounds per square inch. A digital Manometer can measure a broader range of pressures.
Can a negative pressure gas valve cause an undersized gas system?
While a negative pressure gas valve in an appliance can operate at a very low gas pressure, it can have adverse effects on an undersized gas system. This style of appliance can actually rob the gas from other appliances, such as a furnace and possibly cause nuisance outages.
Do you need a BTU rating plate for gas appliances?
Each appliance is required to have a rating plate. This plate will list the BTU ratings of the appliance and required gas pressures for proper operation. See the manufacturer’s instructions for information on locating the rating plate on each gas appliance.
How big is a natural gas pipe?
Size. Most natural gas pipes run up to a nominal size of four inches, although you can get pip that’s up to eight inches in diameter. When you see the flow for natural gas in pipes, these don’t refer to copper pipes. The specification for these is going to be different, with different figures.
What is the nominal size of natural gas pipe?
The nominal size of the natural gas pipe is actually the exterior size. This is generally used as a reference for the pipe, although the interior size of the pipe is less. For instance, pipe with a nominal size of one inch will have an interior size of just under ½ inch (actually .49 inches).
What type of pipe is used for natural gas?
This is dependent on the building codes in your area. Steel and copper are the most common materials. Both PVC and polyethylene (PE) pipes can be used for pipes that are buried in the ground outside a building.
How many BTUs in a 10 foot pipe?
Obviously, the greater the nominal size of natural gas pipes, the greater the gas flow through the pipes. With an 8-inch pipe you’ll have 141,832 BTUs in a 10-foot pipe. For a 150-foot pipe that will be reduced to 36,621. That’s much less, but a great deal more than you’ll find in a pipe with smaller dimensions.
What determines the amount of gas that can pass through a pipe?
The size of the pipe dictates the amount of gas that can pass along the pipe. It’s also worth noting that the longer the pipe, the lower the flow (be aware that the flow of gas is measured in BTUs (British Thermal Units) per hour. If you’re going to be working with natural gas it’s important to be familiar with the sizes ...
What are the functions of different sized pipes?
Different sized pipes have different functions. Smaller pipes carry the natural gas to the appliances, for example, and will almost invariably be short runs of pipe. To run a gas cooker, for instance, you need to have good pressure.
