What size orifice does a natural gas dry use?
You'll find that a 75-drill orifice supplies about 1,400 BTUs per hour with natural gas as the fuel and about 3,000 BTUs per hour with propane. That's a significant difference, and it's due to the different pressures at which the gases are supplied. Cooktop burners typically supply about 40,000 BTUs per hour.
How do you measure flow of natural gas?
Here are the equations to convert mass, volume and density:
- Mass = Volume x Density
- Volume = Mass / Density
- Density = Mass / Volume

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).

Can I use propane orifice for natural gas?
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.

Is a propane orifice bigger or smaller than a natural gas orifice?
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.
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.
How big is the hole in a gas valve?
The smallest hole — which is a little less than 3/64 inches — is 75, and the largest — 1/4 inch — is 1. You can find the number of BTUs that natural gas supplies at normal pressure by looking up ...
How many BTUs per hour is natural gas?
You'll find that a 75-drill orifice supplies about 1,400 BTUs per hour with natural gas as the fuel and about 3,000 BTUs per hour with propane.
What happens if you don't adjust the pressure on a propane gas burner?
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.
Can you feed propane through natural gas?
On the other hand, if you feed propane through a natural gas system, too much gas will flow , and the burner will overheat. If your appliance is designed to be converted between natural gas and propane, it will be expressly designated as such. If so, you can purchase a model-specific kit to do the conversion.
Can you convert a natural gas appliance to propane?
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. The reality is more complicated, and for safety purposes, a conversion is best undertaken by a licensed gas specialist. Advertisement.
