Can you use a natural gas orifice on propane?

They are not interchangeable. You never want to use an orifice that is drilled for Natural Gas on Propane or Propane for Natural Gas. Using a Natural Gas orifice on a Propane grill will produce an abnormally large flame due to too much gas flowing through the hole and can be extremely dangerous.

Does natural gas have a bigger orifice than propane?

The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure. In this case, the higher pressure gas flowing through a larger orifice will result in more gas through the burner and likely, more flame...an unnecessarily large flame.

What size is the orifice for propane?

Propane (LP) orifice sizes typically vary from 0.010 to 0.016′′ diameter, but 0.010′′ appears common, for which energy con- sumption is 548 Btu/hr at a typical 11′′ pressure.

Are all stove orifices the same?

The orifice diameter of these tiny little parts is different between natural gas and propane or LP gas. This means that you will need to change the orifice fittings to match the fuel you intend to use.

What is the difference between propane orifice and natural gas orifice?

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.

Drilling the gas orifice from propane to natural gas

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 happens if you run a natural gas furnace on propane?

You are running the risk of ruining your furnace when you run a natural gas furnace on propane without using a conversion kit. In addition, if you do not modify your furnace or install a blower, it can cause an explosion because of the incorrect ratio of air and pressure.

What happens if you use natural gas on a propane grill?

Because natural gas burns slightly cooler than propane, natural gas grills have valves and burner orifices that are slightly larger to allow for a larger volume of gas to flow. A grill with propane valves should never be used to burn natural gas unless an approved conversion has been performed.

Can any gas range be converted to propane?

Most, but not all, appliances can be converted from natural gas to propane. The biggest sticking point is that natural gas is kept at a lower pressure, and some appliances can't handle the higher pressure of propane even with adjustments.

What is the orifice size for propane and 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).

How do I choose an orifice size?

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 a propane fire pit be converted to natural gas?

Most propane fire pits can be converted to use natural gas as a fuel instead of propane. However, there are some types of fire pits where it is impossible to do the conversion, but the manufacturer will have this noted in the instructions for the fire pit.

Can I convert my Weber propane grill to natural gas?

However, due to safety considerations, the complexity of the technology and gas train components, as well as the level of disassembly required, we don't allow conversions or provide conversion kits. Converting a grill will actually void the warranty on the unit and might create an unsafe situation.

Can you connect a propane grill to a natural gas line?

Once a natural gas line is installed, you will no longer have to worry about running out of gas mid-cook or frequently replacing propane tanks. While you should never hook a propane gas grill to a natural gas line without first converting it for natural gas, it is a relatively easy process.

How do I convert my propane stove back to natural gas?

For an in-ground propane tank, you must call the propane company to empty it, or you can simply use up the propane in the tank, then make the switch to natural gas and leave the tank in place. Depending on local codes, you may have to pay someone to dig up and remove the empty propane tank.

What's the difference between LPG and natural gas jets?

The jet is simply a little screw-in cap with a hole drilled into it. The difference is that the hole in the jet for natural gas is bigger -- about twice as big -- as the hole in the jet for LPG. The reason for this difference is because LPG contains much more energy than natural gas.

Does orifice size affect flow rate?

A reduction in orifice size results in decreased flow as only so much liquid can pass through the orifice. In all of the above cases, the inlet pressure is constant and the outlet pressure is, effectively, zero (atmospheric) as there is nothing to restrict flow on the exit side of the orifice.

How do I choose an orifice plate?

How do you calculate gas flow through an orifice?

Head loss is computed as h=K_mV²_pipe/2g. Standard volumetric flow rate, Q_s, is the volumetric flow rate computed at standard pressure and temperature, P_std and T_std (shown above in variables). Actual flow rate, Q_a, is computed at the gas's actual pressure and temperature.

Can natural gas appliances be converted to LPG?

Most natural gas piping systems can be converted to run LPG.
