Is the propane orifices smaller than the gas?
The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure. Conversely, trying to use a propane appliance with natural gas will likely result in a very small flame or no burner flame at all because of the lower pressure gas and the smaller orifice.
Can propane be converted to natural gas?
You can convert most propane fire pits to natural gas with a natural gas conversion kit. Natural gas conversion kits cost an average of $50, and they work on nearly every propane fire pit. However, it is important to refer to your propane fire pit’s manual to see if it is safe to do so. It is unsafe to use a frayed hose to convert any propane fire pit to natural gas.

Is LPG and natural gas the same thing?
There are also two main differences in the way that LPG (Propane) and natural gas (Methane) are burnt. The first difference is in the energy content. LPG has a higher energy content than natural gas, with 93.2MJ/m 3 vs 38.7MJ/m 3.With this higher calorific value, less LPG is required to produce the same amount of heat.
Can I use propane orifice for natural gas?
Gas types are not interchangeable. Natural Gas orifices will have a larger hole as it is a lower pressure gas and Propane is a compressed gas and the orifices will have a smaller hole. They are not interchangeable. You never want to use an orifice that is drilled for Natural Gas on Propane or Propane for Natural Gas.
What is the orifice size for propane and natural gas?
Low-pressure natural gas delivery pressures are typically 7′′ water column, at the meter, but appli- ances frequently reduce this pressure to 3.5 to 4′′, and propane (LP gas) pressure is typically 11′′. Natural gas pilot orifice sizes typically vary from approximately 0.014 to 0.026 (inches diameter).
How can you tell the difference between natural gas orifice and propane?
A Natural Gas orifice has a larger hole due to its lower pressure. A Propane orifice has a smaller hole due to its compressed gas. It is impossible to replace them. It is undesirable for an orifice to be drilled for Natural Gas under Propane or Propane in order to make it less noticeable.
Are propane and natural gas fittings the same?
The two are not interchangeable; each fuel source requires special gas utilization fittings. If you want to switch between the two, you'll need a conversion kit for the appliances' manufacturer for the installation process.
What size orifice is needed for natural gas?
Propane and Natural Gas Are Supplied at Different Pressures Cooktop burners typically supply about 40,000 BTUs per hour. A propane stove orifice size is about 0.082 inches (drill size 45), but the valve on a similar stove that uses natural gas needs an orifice that is almost 0.125 inches (drill size 35).
What size hole is in a natural gas grill orifice?
A similar stove that provides natural gas must have an orifice that is about 0. However, its drill size allows for an 8,712 inch hole in its valve. (drill size 35) Measures 125 inches....How Do You Size A Flow Orifice?where:V2= fluid velocity through the orifice hole, m/s3 more rows•Jan 29, 2022

What size orifice do I need for propane grill?
If your grill has a BTU input of, say, roughly 14,000, a natural gas grill needs a #49 orifice while a propane-fueled grill needs a #57 orifice.
What Does Orifice Size Mean?
The operating pressure of your machine is determined by the size of the aperture of the nozzle. As a general rule, the smaller the orifice, the greater the water flow restriction through the machine.
Do You Need a Natural Gas Orifice for Your Application?
An orifice is required for the operation of a gas grill. The size of the orifice hole dictates the BTU rating of the grill as well as the kind of gas it uses.
How many inches is natural gas?
Natural gas has more mass but is usually regulated between 2 inches and 9 inches whereas LP is always regulated at 10-11 inches for low-pressure appliances. Orifice sizing charts will be in columns of Inches starting with 2 and moving up to 11 inches for LP gas. The rows of the chart will show BTU’s.
How is gas pressure measured?
Gas fireplaces, barbecues, grills and smokers use a very low-pressure setting well below one pound per square in ch so we measure the pressure in terms of water-column displacement.
