The size of the orifice hole for a natural gas grill can vary slightly depending on the specific model. Generally, the orifice hole for a natural gas grill should be approximately 1/4 inch in diameter.
In some cases, the orifice hole may be as small as 1/8 inch or as large as 3/8 inch. The purpose of the orifice hole is to regulate the flow of gas from the gas supply line to the burner. The size of the orifice hole should be carefully matched to the BTU output rating of the gas grill to ensure that the proper amount of gas flows through the orifice to the burner.
If the orifice hole size is too small, the heat output will be decreased. If the orifice hole size is too large, the heat output will be increased, causing a potentially dangerous situation. It is important to select the correct size orifice hole for the grill to ensure safety and proper operation.
Is natural gas orifice bigger than propane?
The unfortunate answer is that there is not just one simple answer to this question. Natural gas orifices come in different size options as do propane orifices, so it depends on the orifice size being compared.
Generally speaking, natural gas orifices will be slightly larger than a propane orifice in the same size option. This is because natural gas operates at a lower pressure than propane, so a larger orifice size is needed to draw the same amount of fuel.
This applies to both a standard domestic orifice and a high-pressure orifice. The size difference between natural gas and propane orifices is typically very small, but it can vary depending on the specific applications.
For specific size comparison details, it is recommended to consult a qualified professional.

What does a gas orifice do?
A gas orifice is a device that is used to regulate the flow of a gas. It is typically used in industrial settings and in the construction of gas-powered equipment. The orifice typically consists of a small hole in a valve body or an attachment to the pipe connecting two pieces of equipment.
The size of the hole is calibrated to deliver a certain flow rate of gas. This is done by manipulating the gas pressure at which the gas flows through the hole.
Gas orifices are used to regulate the flow of gases for a variety of purposes. They are used to control the amount of gas going into furnaces, ovens, water heaters and other appliances that use controlled amounts of gas to function.
They are also used to maintain pressure in various locations throughout a manufacturing process. By controlling the gas pressure, the flow of gas can be regulated for maximum efficiency and safety.
In addition to their use in industrial settings, gas orifices are also used in the construction of cars and other vehicles. They are used to regulate the amount of air and fuel entering the engine so that it can run efficiently and effectively.
Gas orifices essentially act as throttles, allowing the engine to pull enough air and fuel through the combustion process while still maintaining the desired speed, power and fuel economy.
What is the difference between propane orifice and natural gas orifice?
Propane and natural gas orifices differ primarily in their BTU ratings. Propane orifices are typically rated between 363,000 and 540,000 BTUs of energy per cubic foot, while natural gas orifices are usually rated between 1,000 and 1,200 BTUs of energy per cubic foot.
Additionally, propane orifices are typically larger in size than natural gas orifices, which means they provide more gas per given time period. This is due to the higher pressure of propane compared to natural gas, as propane is typically stored under higher pressure using a propane tank.
Moreover, propane orifices require different materials for manufacturing as the burner and copper lines must be rated for higher pressures, whereas natural gas lines and materials can typically be lighter than those used for propane.
Lastly, propane orifices must be installed, adjusted, and maintained according to strict safety guidelines, whereas natural gas orifices are often simpler to install, adjust and maintain.
How do I know my orifice size?
When sizing an orifice, there are several factors to consider. The most important is the type of flow you will be using. If it is for a liquid, it is important to know the viscosity of the liquid and the maximum flow rate.
For gases, it is important to know the type of gas, its temperature, pressure, and velocity. To determine the right orifice size, you should calculate the differential pressure of the flow you intend to use and then use this value to determine the orifice size.
The differential pressure is calculated by dividing the upstream pressure by the square root of the absolute pressure and the square root of the absolute temperature. Once this is calculated, the orifice size can be determined.
Generally speaking, larger orifice sizes will result in higher flow rates. Additionally, it is important to ensure that the orifice size is not too large to avoid excessive erosion of the orifice and a possible blockage.
Once you have determined the correct orifice size, you can proceed with installation. For liquids, the orifice should be installed vertically and for gases, horizontally, as this will provide the most efficient flow.
Do you need a regulator to convert propane to natural gas?
No, you generally do not need a regulator to convert propane to natural gas. However, if your propane appliance is designed to connect to a natural gas line, then a regulator may be needed to ensure that the propane is delivered at the appropriate pressure.
Additionally, if you are using a propane system where the pressure of the propane is lower than the pressure of the natural gas line, then a regulator is required to increase the pressure of the propane prior to use.
Regulators for conversion of propane to natural gas may be purchased from most major hardware stores. Prior to purchasing a regulator, you should consult a qualified professional to ensure that the regulator is appropriate for your particular application.
Can you change the orifice from natural gas to propane?
Yes, it is possible to change the orifice from natural gas to propane. The process involves changing out the existing orifice to the propane orifice and adjusting the gas pressure to the proper setting.
This often requires special tools and knowledge, so it is best to have a professional do the job. When changing the orifice, all of the connections must be checked for leaks and the appliance’s overall operation should be tested to ensure its safe operation.
It is also important to note that many appliance and furnace manufacturers require specialized propane orifices, so it is important to consult with the manufacturer before attempting the job.
What happens if I use a propane orifice natural gas?
Using a propane orifice for natural gas can be dangerous, as propane has a much higher energy content than natural gas. The higher energy content will create higher pressures and more heat, which can lead to increased wear and tear on the appliance, potentially resulting in a fire or explosion.
Additionally, propane has a different chemical makeup than natural gas, so using a propane orifice for natural gas won’t guarantee the correct amount of gas will flow into the appliance. This incorrect flow rate can cause the appliance to run inefficiently, produce dangerous levels of carbon monoxide, or create problems with the pilot light.
To ensure safety and top performance, the proper orifice needs to be used according to the appliance’s instructions or local codes.
Are natural gas or propane orifices smaller?
It depends on the type of natural gas or propane being used as different fuels require different sized orifices. Natural gas orifices are typically sized between #53 and #55, while propane orifices usually range between #55 and #58.
Natural gas orifice diameters range from 1.5 – 3.5 mm and propane orifices typically range from 2.4 – 5.0 mm. Natural and propane orifices are always smaller than the size of the inlet connection, so that pressure drop through the orifice can create the necessary difference in pressure to create the flow of gas.
It is important to note that the correct size orifice must be selected and installed according to the manufacturer’s specifications in order to ensure proper and safe operation of the fuel system.
How do you convert natural gas to propane?
Converting natural gas to propane can be done through a process called gas fractionation. This process involves fractioning, or separating, raw natural gas into different components, such as butane, ethane, propane, and nitrogen.
Natural gas is mostly composed of methane, which is too gaseous to be stored or transported.
Gas fractionation can be achieved by several different methods, including cryogenic processing, scrubbing and absorption, and adsorption. The specific type used depends on the type of natural gas and the desired end product.
Cryogenic processing is a process in which liquid nitrogen is added to natural gas, freezing out and separating the various components. Components of different density can then be separated out.
Scrubbing and absorption is another method used to fractionate natural gas. This process involves scrubbing raw natural gas with a solvent to separate out and absorb the different components into a gas analyzer.
Adsorption is a process in which raw natural gas is projected against an adsorbent solid, such as zeolite or activated carbon. The process captures the desired compounds from the gas stream, allowing them to be collected and separated.
Each of the previously listed processes have their own advantages and disadvantages and it is important to choose the right process for the conversion of natural gas to propane. Gas fractionation removes the less desirable components of natural gas and produces a clean, useable product, better suited for storage and transportation.
