Can you convert LP gas to natural gas?
Conversion involves replacing the propane regulators and orifices in the appliance with ones designed for natural gas. Conversion kits are available for many gas appliances, but the actual conversion work should be done by a licensed installer.
How do you change an orifice from propane to natural gas?
Steps for Converting a Furnace to Propane Natural Gas (Basic Over)
- Turn the gas and power off the unit.
- Take pictures and write down the wiring connections to the gas valve.
- Disconnect the gas valve.
- Locate the orifices/jets and with the correct size wrench remove them.
- Install the new orifices.
Which orifice is larger propane or natural gas?
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.
What is the difference between a natural gas orifice and a propane orifice?
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 natural gas?
Natural gas pilot orifice sizes typically vary from approximately 0.014 to 0.026 (inches diameter). Examples include 0.026′′ for a commercial cook- ing appliance pilot (1,835 Btu/hr at 4′′ pressure), and 0.018′′ for a natural gas water heater pilot (879 Btu/hr at 4′′ pressure).
What happens if you use a natural gas orifice with propane?
Attempting to use a propane appliance with natural gas will result in a very small flame or no burner flame because of the lower pressure gas and the smaller orifice. It is not possible to convert appliances from electricity to propane.
Why does natural gas require a bigger orifice than propane?
Natural gas is a much lower pressure gas than propane and converting the appliance to one or the other gases requires that the differing pressure is compensated for. The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure.
