The size of natural gas pilot ricors is typically around 0 mm. With a 266-inch diameter (inches). Although there is no universal definition for the word 0, it is a good illustration. A commercial cooking appliance pilot’s operating pressure is 0. This gas water heater pilot (879 Btu/hr overpressure) is an alternative to a direct water heater pilot.
What orifice size is required for a natural gas grill?
Typical cooktop burners produce around 40,000 BTUs per hour. The orifice size on a propane stove is around 0.082 inches (drill size 45), however the orifice size on a natural gas stove is almost 0.125 inches (drill size 35).
How much pressure is required for a natural gas grill?
Invest in a regulator for your natural gas barbecue for safety reasons. A pressure rating of 4″ WC is required for natural gas barbecues (inches per water column, a unit of pressure).
Pressure regulators lower the PSI so that your gas lines stay intact when you run gas to different appliances like your water heater, furnace, or gas grill. This is why it’s crucial to keep the pressure on your gas grill under control. Your city or county provides natural gas at a certain pressure. To find out how much pressure you have, talk to your contractor.
Is it propane or natural gas that has the larger orifice?
Appliance conversion entails replacing gas orifices, burners, and/or appliance regulators in order for an appliance to run on a different fuel. These internal fittings and gas usage connections are made to work with a certain gas at a given pressure. Because natural gas has a lower pressure than propane, changing the appliance to one of the two gases necessitates compensating for the pressure difference. Connecting a natural gas appliance to a propane piping system, in other words, will result in appliance failure and possibly danger. This is due to the fact that natural gas orifices are larger than propane orifices due to gas service pressure. In this situation, the greater pressure gas passing through a wider orifice will cause more gas to pass through the burner, resulting in more flame…an unnaturally enormous flame. Because of the lower pressure gas and the smaller orifice, using a propane device with natural gas will likely result in a very small flame or no burner flame at all. This is the primary goal of converting a propane to natural gas or natural gas to propane equipment. Furthermore, appliances cannot be switched from electricity to propane or the other way around.
What size natural gas BBQ pipe do I need?
There are a few things to keep in mind after you’ve gotten the grill out of the box, installed it, and are ready to start impressing folks with your cooking skills.
These pointers will ensure that your natural gas grill is ready to use right away!
1) WCP (water column pressure) – Natural gas grills are designed to operate at specific WCPs (WCP). The WCP for your grill can be found in the owner’s manual. This should be checked by a gas specialist at the supply line.
2) Natural gas fittings – If fittings are required on your gas line, straight pipe nipples should be used rather than flare fittings.
Flare fittings can damage the end of your natural gas hose, limiting the amount of gas that gets to your grill.
To complete the setup, for example, if your grill connection is 1/2″ and your gas line is 3/8,” you’ll need a 1/2″ straight pipe nipple, a bell reducer, and a 3/8″ straight pipe nipple.
3) Shutoff valves – We recommend having both an interior and an outside shutoff valve for safety reasons.
When using the grill, make sure these are both fully “open,” and when not using the grill, we recommend that they be “closed,” preventing gas flow.
4) 10-foot flex hose To connect your grill to the supply line, our natural gas grills come with a 10-foot flex hose. We do not advocate connecting more than one hose together because it may affect the grill’s functionality. If you need a length longer than 10-feet, consult your owner’s manual for advice on hard piping your supply line to your grill.
What is the difference between natural gas and LPG jets?
Liquefied petroleum gas, on the other hand, is derived from the distillation of crude oil (see this Question of the Day for details). It is largely made up of propane (C3H8). Propane has the good virtue of condensing into a liquid when compressed. This makes it considerably easier to store in a tank than natural gas, which is difficult to compress.
When purchasing a gas stove, you can readily observe the difference between natural gas and LPG. Normally, two sets of jets are provided, one for natural gas and the other for LPG. Each burner has one jet installed. The jet is little more than a small screw-in cover with a hole drilled in it. The difference is that the hole in the jet for natural gas is larger than the hole in the jet for LPG (about twice as big).
The discrepancy is due to the fact that LPG contains significantly more energy than natural gas. Natural gas contains about 1,000 BTU (British thermal units) of energy per cubic foot. 2,500 BTU are contained in a cubic foot of propane. If you take a gas appliance that is set up for natural gas and convert it to LPG, the appliance will run more than twice as hot. A water heater, for example, appears to be hot enough to ignite a fire.
Is a regulator required for my natural gas grill?
When switching a grill from one gas type to another, you must not only replace the orifices, but also the appliance regulator (if you are converting from Natural Gas to LP). Some grills don’t require an appliance regulator, so if you’re switching to LP, you might be able to do away with it. You will, however, require a regulator to connect to the tank.
The regulator may or may not be convertible. Check to see if the appliance regulator can be converted. The fitting at the top of the regulator will tell you. It will be hexagonal in shape.
A natural gas-only non-convertible regulator will have a circle at the top with a line running down the center.
If your grill has an appliance regulator, you’ll need to convert both the regulator and the grill at the same time. Also, adding an appliance regulator when changing a grill from LP to Natural Gas is a prudent safety measure.
An appliance regulator is required on all natural gas barbecues. It controls the amount of pressure that enters the grill.
You’ll need a wrench and a regulator to convert to Propane (or Natural Gas).
1. Using a wrench, unscrew the cap at the top of the regulator.
2. Remove the plug from the bottom of the cap, rotate it, and snap it into the back of the cap according to the gas type you require. (The gas type will be molded into the plug that goes into the cap.) It will have a NAT if it is set to Natural Gas. The gas type you are converting to will be inserted into the cap (the bottom side of the cap will say LP).
3. Replace the regulator’s cap with a twist.
4. Connect the manifold to the regulator.

Do you require a natural gas pressure regulator?
A natural gas regulator performs two critical functions in the delivery of natural gas to your home: pressure reduction and pressure regulation.
Natural gas is delivered to houses via a huge network of pressurized pipelines by a natural gas utility. These networks connect gas collecting points with the towns and cities that consume the fuel. These pressurized gas lines allow gas to be transported through the pipe network to residences and businesses. When the gas arrives at your site, the pressure must be reduced to a level that your appliances can handle.
Direct-operated or self-operated pressure-reducing valves are the most common types of natural gas regulators. These valves get their name from the fact that they have an inbuilt spring valve mechanism that reduces pressure without requiring any additional energy.
Within direct-operated pressure-reducing regulators, a valve with an adjustable spring controls the pressure. The spring valve applies pressure in the gas line against the opposing pressure, allowing the valve to open just enough to pressurize the downstream house side to the required pressure level.
The second important function of natural gas regulators is to restore normal gas pressure in the home. The gas is often delivered at a higher pressure than necessary by the plumbing outside the structure, and that pressure might rise and fall. The gas pressure in the pipes feeding to the various appliances could change or decrease significantly without a natural gas regulator.
A natural gas regulator restores normal gas pressure by sensing the pressure downstream of the regulator and adjusting the spring valve as needed to maintain a constant flow of gas. This is accomplished through a mechanical connection between the regulator’s spring valve and a diaphragm chamber filled with gas from the downstream output side. As the pressure on the downstream side drops, the diaphragm interacts with the spring valve to allow additional gas to flow from the intake side, bringing the pressure back to normal.
What happens if you use a propane orifice with a natural gas orifice?
Running propane through an orifice designed for natural gas will result in a huge flame and a lot of soot. The flame will be larger, causing damage and maybe an explosion. Because the orifice jet for natural gas is larger than the one for propane, this is the case.
When you use propane on a natural gas barbecue, what happens?
If you wish to use natural gas in your barbeque grill, the simplest plan is to simply get a grill that is made for this purpose. Instead of “liquid propane grill,” such appliances will simply be branded “natural gas grill.” Although you may need to special order them, virtually all major grill manufacturers provide grills with special valves and burners designed to use natural gas. Natural gas grills have somewhat wider valves and burner orifices to allow for a larger volume of gas to flow because natural gas burns slightly cooler than propane. Unless an approved conversion has been made, a grill with propane valves should never be used to burn natural gas.
Is it possible to convert a propane grill to a natural gas grill?
In general, no. Many grills can be converted, and conversion kits are available. In addition, several forums and YouTube videos demonstrate how to convert grills that are believed to be impossible to convert. However, they are “unofficial hacks,” which void any warranty you may have and almost certainly invalidate any insurance you may have in the event of a fire.
