Can you convert a propane Mr heater to natural gas?
Mr. Heater Fuel Conversion Kit will covert an MH25LP or H22L from Liquid Propane to Natural Gas fuel. Fuel Conversion kit for changing LPP overheads to NPP and from LP to NG. Kit includes all necessary labels and components required for the complete conversion.
Can you change the orifice from natural gas to propane?
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.
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).
Are natural gas and propane interchangeable?
The two are not interchangeable; each fuel source requires special gas utilization fittings. Natural gas is a utility that is only available in certain areas, bringing the gas into the home via underground pipes. Propane is stored in tanks that need periodic refilling and replacement.
Is it expensive to convert from propane to natural gas?
This substantial cost difference may lead homeowners to consider converting from propane to natural gas once natural gas becomes available in their neighborhood. The conversion process can be complicated, and the cost can range from under $1,000 to more than $5,000.

Can I use a LPG heater on natural gas?
LPG (propane) and natural gas (methane) appliances are not interchangeable — they must be converted.
Is a propane orifice bigger than a natural gas orifice?
Natural gas orifices are larger than propane, to allow extra fuel to flow through at lower pressure. Propane orifices are smaller, to account for the higher pressure and increased energy output.
How do I know my 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.
Is there a difference between natural gas and propane regulators?
Propane regulators and natural gas regulators are not interchangeable, though they both operate in the same fashion. A natural gas regulator is comprised of five components: set screw, spring, rod, diaphragm and valve.
How to convert gas appliance orifices from LP to natural gas?
The manufacturer includes a set of brass orifice fittings (shown below) that must be used when converting the cooktop from natural gas to LP or propane fuel. A typical gas appliance spud or orifice will be marked with A letter: L (for LPG) or N (for natural gas) A number: (such as 44 or 122) indicating the orifice opening diameter.
What happens if you change the orifice of a propane burner?
Changing the burners to ones with the correct orifice size. If you don’t make the necessary modifications to adjust the pressure, the consequences can be severe. Feeding natural gas through a system designed for propane could result in insufficient gas to light the burner, and unused gas could linger and cause an explosion.
Where can I find data on propane orifices?
Similarly, you can find the same data for propane by consulting a propane orifice size chart. If you’re considering converting between natural gas and propane, you can look up the combined data for both natural gas and propane on a natural gas propane conversion chart.
Can a propane water heater be converted 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. Some propane appliances, such as water heaters, cannot be converted and must be replaced.

Can a propane stove be converted to natural gas?
This is one of the more simple applications of propane conversions. Most of the stovetops on the market today come set up ready for natural gas. This is because it is more widely used in the marketplace. All of the orifices are installed in the factory to handle the correct BTU rating for natural gas.
