Many propane grills can be converted to natural gas, but not all of them. Some grills aren`t set up for conversion at all, while others don`t have a compatible conversion kit.
If you have gas, you may have tripped the excess flow valve. So, turn off the control knob, disconnect the regulator, wait 30 seconds and reconnect the regulator. Turn on the tank valve slowly, then light grill according to lighting instructions. If flames are still low, repeat this process up to three times.
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).
If you don`t know what size that tiny hole is, spend $10 on a wire size drill bit set and use the shank end (the opposite end from the cutting end) as a gauge pin. The largest one that will fit in the hole is your orifice size.
In other words, connecting a natural gas appliance to a propane piping system will result in appliance malfunction and possibly danger. The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure.
Long version: a propane barbecue includes a short (2`) hose/regulator combo, a natural gas barbecue includes a long (10`) hose and a brass quick disconnect for connecting to your home`s gas line. This longer hose and set of brass fittings is an expensive set of gear and their inclusion makes the price go up.
Typically, on a 70 F day, the propane may have a pressure of approximately 145 psi. To help ensure safe operation of the appliance burner(s), a regulator is provided at the inlet to the appliance to maintain a steady pressure of about 2 psi to the burner(s).
The gas valve may need to be adjusted if the reading is low or high. All gas valves have an adjustment screw. To increase, turn it clockwise with the heater running and manometer attached. Turn it 90 degrees and read the manometer until you`ve reached the proper pressure.
If your charcoal doesn`t stay lit, there`s a chance it doesn`t have enough ventilation. Just like putting out a candle with a small cup (actually called candle snuffer) when there`s no more air around, the charcoal extinguishes. The good news is that you must only allow some ventilation and try again.
A weak flame is often a signal that the safety regulator on the propane line—that aluminum device that sits near the end of the hose that attaches to the tank—has been tripped, slowing the flow of gas to a trickle.
Start by turning everything off, including your gas flow at the tank. Disconnect the regulator from the tank and allow everything to sit for about 5 minutes. Reconnect the regulator to the tank and slowly open the valve all the way. Wait for 30 seconds before trying to light the grill again.
The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine. This causes the pressure to increase. Choosing a nozzle with too large of an orifice will reduce operating pressure.
This 1.1 mm 3.0 sized orifice is meant for pressure washers with lower PSI ratings to help increase the amount of foam generated by the foam cannon.
Orifice Specifications. Generally, a square-edged concentric orifice plate mounted between a pair of weld neck flanges of minimum 300# ANSI rating for line size 2″ and above. Flange taps shall be used for line sizes up to 12″ while D-D/2 taps shall be used for line sizes 14″ and above.
Gas orifice sizes are typically measured by the diameter of the hole size. It is expressed in either inches or millimeters, and it determines the flow rate of gas through the orifice. A larger diameter gas orifice allows for a higher flow rate of gas, while a smaller diameter restricts the flow.
The orifice is the hole that is drilled in the orifice plug. This is where the gas escapes from all your piping and enters the mixing bell of the burner. The orifice is not where the flame comes out of the burner…. that`s the head.
Here in North America, gas grills run off of two basic types of fuel; propane (also known as LP, LPG or liquid propane), and natural gas, which is usually made up mostly of methane. Each Weber gas grill sold in North America is designed to be used with one of those two types of fuel.
All natural gas grills are required to have an appliance regulator. It regulates the pressure going into the grill. It is good idea to have one on an LP grill that has high BTUs. These grills will include an appliance regulator that is convertible.
Bottom Line
There is NO performance difference between propane and natural gas unless you`re grilling in the arctic. The only significant difference is the convenience of natural gas and never running out of fuel. Your choice ultimately boils down to which fuel sources you have access to and the costs in your area.
Better for the environment: Cooking with gas is better for your health because food prepared on a gas-powered appliance contains fewer carcinogens compared to food that has been charred on a charcoal cooking surface. Gas grills also have a much smaller carbon footprint, about 1/3 of a charcoal grills` carbon footprint.
Generally, propane pressure should be between 100 and 200 psi to ensure that the liquid propane gas remains in a liquid state. Normally, the pressure inside a propane tank fluctuates slightly based on the outside temperature.
The built-in regulator that comes with the Weber Q maxes out at about 1 PSI and is not independently adjustable. I replaced mine with a High-Pressure Adjustable Propane Regulator that goes from 0-20 PSI.
How to Tell if Your Gas Grill`s Regulator Is Bad. There are several signs that show that your gas grill`s regulator is bad. These include your burners lighting up unevenly, yellow/orange or lazy flames, flames that float above the burner ports, and a popping sound when you turn the gas burners on or off.

Mule 610 will not start. Was running fine, plowing snow and it starting acting like it was running out of gas and stalled. Put gas in put it won’t start and acts like it is not getting gas. Could the gas line have frozen due to the depth of the snow?

ANSWER : Sounds like your mix is off and it’s fowling the plugs. probably too rich. make sure the level in your carb bowls isn’t too high. Really sounds like you should clean and bench set your carbs. Especially if a plug change helps but doesn’t last, then it’s got to be your fuel mix, or maybe timing.

I have had two small Coleman ‘Frontier PZ’ propane lanterns for a number of years with no problems. Last year one of them started shutting down for no apparent reason – it would light normally, burn for 4 – 5 minutes and then go out. This summer the second lantern has started doing the same thing. Changing gas cylinders seems to have no effect, nor does a new mantle fix the problem. It’s hard to be certain but as I can’t hear any gas hissing it’s as if the jet gets blocked after a few minutes alight. Turn off the gas, leave the lantern alone for a while and it will relight ok, though it will still only burn for a few minutes before going out again. Any ideas?
ANSWER : There is something in the jets or the piping to the mantels, you my find spider webing there, if you did no cap the port where the tank goes some small friends might have wanted to go camping with you.

Snow blower 1 year old, was using it ran out of gas , put in new gas, went to start, it ran for few seconds then dies,, prime it it runs few seconds dies, has NEW gas ans new plug, only runs for seconds after you prime it tons of times
ANSWER : If it has a fuel filter on it change it and that should get you going again. If not the dirt that was in the tank is prob in the carb cleaning the fuel bowl and jets should get you up to par. Hope that helps
