Do you need an orifice for natural gas?
You cannot operate a gas grill without an orifice. The orifice hole size determines the BTU rating and the gas type of the grill. 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.
Is the orifice bigger natural gas or propane?
Because of gas service pressure, natural gas orifices are larger than propane ones. Attempting to use a propane appliance with natural gas will likely result in a very small flame or no burner flame because of the lower pressure gas and the smaller orifice.
How do you measure a gas orifice?
Divide the flow of the liquid by the velocity of the liquid to determine the area of the orifice in square feet. In the above example, you would divide 8 by 2. The total area of the orifice would be 4 square feet.
Can you run propane through natural gas orifice?
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. This is the underlying purpose of an appliance conversion from propane to natural gas or from natural gas to propane.
What’s the difference between a natural gas orifice and a propane orifice?
Natural gas is fed at a smaller pressure than propane, so to get the same heating value (usually measured in BTUs), a natural gas orifice has to be smaller than a propane one. This suggests that you can convert a natural gas appliance to a propane one and vice versa by changing the orifice on the gas valve.
