The venturi tubes should go over the gas orifice. If the tubes were to drop off, you could have a fire outside of your grill and possibly an explosion.

Grill burner will not burn like the other


Dynasty burners are replaceable and they are very good appliances (when they're actual dynasty, manufactured by jade).
About 90% of the time someone complains about burner flames or heat it is the check valve needing to be reset. I explained this earlier but let me know if you need to know how to do this.
On the rare occasion the check valve is not the problem (and 90% could actually be very low because this is almost always the problem!) the burner could need to be cleaned or replaced or the gas orifice and valve could need to be cleaned or replaced.
Dynasty burners are very heavy cast iron, single venturi "H" burners. Although coated cast iron is quick to oxidize and sometimes because of the coating the rust will start from the inside out. Lift the burner from the back of the barbecue and slide it away from you. Check to see if it is corroding from within.
The single venturi tube extends from the bottom of the burner into the control panel where it slides over the gas orifice at the tip of the control valve. It is possible for the gas valve to get a small insect crawl in through the orifice and build a nest inside the small cavity inside the control valve.
Remove the burner to reach through the inner firewall with a ratchet to pull the orifice and then check the inside of the orifice and the inside of the valve behind the orifice. If something is clogging the orifice the gas will flow unevenly and you may have flame-flashing inside the control panel which will destroy the lubrication in the control valves and will destroy the ignition parts inside the control panel.
I suggest the check valve solution with the drip tray removed so you can look from under the control panel for gas leaking through the air holes in the venturi tubes. Also, remove the control panel and leak-test the valve with soapy water because if previous flashing occurred the first casualty is usually the seal between the valve and the gasket which can lead to more leaking gas.
Check valve:
Turn everything off (tank and bbq).
Disconnect hose and regulator from LP tank.
With tank disconnected, turn the BBQ on. Turn every valve to "high" and leave it for 5 minutes.
Turn everything off -- completely off.
Reconnect tank but turn the tank on very, very slow. The check valve problem occurs when gas "hits" a swing arm too hard as the gas leaves the cylinder so turn the cylinder on very slow and then relight the grill.

Gas flame burning yellow?


Does your grill or pool heater have a yellow flame instead of blue? If your propane tank is not just about to run empty, then you can probably thank little spiders.
When a gas burning appliance sits idle for a week or more outdoors, spiders like to build nests in the venturi tubes (that's the tube with the holes in it where the combustion air gets sucked in). This changes the way the combustion air mixes with the gas and causes the gas to not burn completely. The incomplete combustion is not very hot, and so the flame appears yellow. This is not efficient. It wastes gas, is too cool for grilling steak and creates soot residues. This is very common on gas grills (bottled propane or piped natural gas). It also happens to pool heaters.
Fortunately, the fix is easy, and you usually don't need to take anything apart. Get a piece of stiff nylon string from a weed-wacker, about 12 inches long. With the burner cool, push the string into any hole in the venturi tube and spin it by rolling it between your fingers. The spider nests are sticky (made from the same stuff as spider webs) and they usually adhere to the nylon string.
Not sure what the venture tube is? It's going to be between the valve and the burner. The valve shoots a stream of gas into the venture tube through a pinhole nozzle called an "orifice". You can do a Google image search for BURNER VENTURI TUBE to see lots of different types. Every gas burning appliance uses some form of venturi tube.
Good luck. Al K

No gas enters tube. nat gas valve on. ignitors sparking. orafices clean.


Glad you cleaned the orifices. Did yo also clean the burners and their venturi valves when you had the burners out? If not, I suspect you may have a spider colony that has built nests in each venturi valve. If so, it stops the gas flow to each burner dead in it's tracks.

Hope this helped you and thanks for choosing FixYa.

How do you open venturi tubes to clean?


If you remove the burners, the Venturi Tube is part of the open end of the burner that fits over the burner orifice. It should look like a slot on each side of the burner. There's really nothing to open, once the burner is removed.

Hope this helped you and Happy Grilling!!

Hi! Hope you can help us--we have a Brinkman 4-burner grill that is about 5yrs. old. Last yr. we started having problems with burner #2 not lighting all of the way and the burners all looked a bit rusty,...


I think you husband is trying to clean the wrong thin. The venturi tube is part of the burner itself. It's the open end of the burner, that has an air intake adjustment on it. It fits over the burner orifice. He may be hitting the orifice, which in fact may be clogged. Remove the offending burners and he will be able to see the burner orifice, which can be removed with the appropriately sized wrench. Once removed try blowing through it. If air doesn't blow through, it's clogged. Clean it with a straight pin that is no larger that the orifice hole. You do not want to enlarge it. Also, the new burners may need adjustment of the venturi for the proper air to gas mixture. Consult you Owners Manual on how to adjust it.

Need an Owners Manual? Go to http://www.brinkmann.net/my_grill.aspx and enter the Model Number of your grill.

Hope this helped you to solve the problem. Please don't forget to rate my response to you. Thanks!

We're trying to clean the venturi tubes on our Blue Ember FGF50069 gas grill but we don't understand how to disengage the tubes from the burner. Can you help us? Are there any images of the...


The Venturi tubes are part of the burner, where it goes over the burner orifice. You can remove the burner(s) by disengaging them from the burner holder. Which should be at the inner rear of the grill's burner compartment. Then the burner will slide off the burner orifice.

FYI - A couple of years ago, there was a massive recall on the Fiesta Blue Ember Model grill. Don't know if your is old enough to fit that category. So I have included a link to the Consumer reports Website, that liist the Serial Number of those involved.

Yellow flame


Hello,
You may have a rusted, clogged or damaged burner or venturi tube. With a flashlight, check for spider webs, wasp nests or dirt (mud) dauber nests in the opening of the venturi tube where it connects at each gas valve orifice. Clean it out manually or blow it out with air compressor. Make sure the air adjustment opening (on the end of the burner's venturi tube) has not been changed. If it's closed too much, it will be difficult to light and cause lazy yellow flames. If it's not clogged, the burner may just be old and rusted and the burner holes are not allowing very much gas through anymore. It's also possible the burner has rusted so bad, the burner holes have been enlarged, it is falling apart or has cracks along the burner seams. If so, replace the burner(s) immediately. It is unsafe to use. Your local propane co can usually order the parts you need and some will even do the work, if you are uncomfortable doing it yourself. Bring with you the Make, Model and Serial number of the grill, so they can order the correct parts for your specific grill. Also specify whether it's natural gas2_bing.gif or propane.
