Question about Weber Q300 Grill

1 Answer

Gas flow too high

Hi on my Q300 the gas flow is tremendous and the BBQ is overheating. Initially it started on the large dial two ring burner, but now is also on the single centre burner also. The temperature dials don't really have much effect, I.e., it's either all or nothing. Does this indicate the regulator at the bottle is at fault or can it be at the BBQ end?

SOURCE: won't light properly or vary the flame

Hello,
You're probably turning the LP tank valve on too fast. Close the tank valve, disconnect it and reconnect it. Then very slowly turn on the tank valve. Make sure all your grill knobs are closed. Light one at a time and turn to low setting. After they are all lit, slowly turn up the heat on each as needed. Hope this helps. Douglas

SOURCE: Need to know how to reset the LP Gas flow for a

If you just installed a new, full tank of propane and turned it on and the burners wouldn't light.

Turn the tank off, disconnect from the grill hose (you'l hear a whooshing sound and smell gas, but that's alright). Wait several minutes and reconnect the hose to the tank. Turn the gas valve on very very slowly, until it's full open. Now, try lighting your grill.

Remember, you will need to turn the tank valve on very very slowly every time you change tanks or turn the tank off after grilling.

What happened was this ... When you turned the tank on quickly it locked up the grill's gas regulator. Doing what suggested usually solves the problem. Oh, one other thing ... be sure your tank is not empty. The grill you have uses a lot of gas.

SOURCE: Sometimes Q100 will not light

Nope, the regulator is not the problem. It's the LP tank regulator. The new OPD heads on the tanks are designed to prevent over filling. All 20lb cyclinders now have them. But, it's easy to solve.

Turn off the tank, disconnect the s/regulator from the tank, wait 5 minutes. Then reattach the hose/regulator to the tank and turn the tank on very, very slowly, until it is completely open. Now, try lighting the burners one at a time and turn them up to high. That should have solved your problem, by allowing the regulator to reset itself.

Just remember to always turn the tank on very, very slowly after turning the tank valve off each time.

Hi ircatlin...

ONLY TO THE FOLLOWING IN AN OPEN AREA AWAY FROM FLAMES/FIRE/IGNITION SOURCES.
To answer your question if the gas regulator can get stuck...the answer is YES.

Check to make sure gas is getting thru the regulator...to do this disconnect the hose going to the burner controls...turn on the gas at the tank and listen and smell for gas coming out...if there is no gas coming out, you can sometimes tap lightly the gas regulator and it will free the sticking valve inside and let the gas flow...if the tapping does not work, the replace your regulator as it is faulty.
Please take time to rate me

I have a Vermont Casting 3 burner BBQ, Model VM400XBP, 36,000BTU grill that won't go above 300 degrees? How can I fix it?


It could be something as simple as a triggered safety feature within the gas tank itself. These new tanks will react to the gas leaving the tank at a high flow rate causing low burner temps. To remedy: shut off gas and remove tank. Open and close all valves on the grill. Reattach the tank and SLOWLY open the valve 2 turns. Then retry. See page 13

When I changed my gas tank, the gas flow would not return


The new style2_bing.gif OPD valves have a small brass ring located in the female fitting on the LP tank. Over time this ring can work loose and then it does not allow the male fitting to fully depress the OPD valve thus reducing your gas flow
Using a small flat bladed screw driver tighten the small brass ring This should solve your problem
IF not you might want to remove the cap (white) on your regulator and try slowly adjusting the regulator, make small adjustments and try the BBQ My Weber if I set the front and back burners to MED I get right at 350 degrees in 60 degree outdoor temps. Adjusting the regulator will take some time to get it right but If it is not your tank it is most likely your regulator out of adjustment

New BBQ chaged from propane to NG


Hello. The conversion of any gas appliance usually requires changing orifices, regulator and burner. Then once those changes are made you can adjust the gas flow. The difference in the orifices is this.
Natural gas orifices are larger than liquid propane orifices simply because the gas pressure for the natural gas is lower.

I would double check to be sure that you have installed the correct orifice. Also, you can adjust the amount of gas by turning the orifice in or out, using that socket.

Please call the uniflame technician directly if you still have a problem 800-762-1142 Joe

Hi 3 of my 6 gas burners won't light. Can you help me with this?


I had the same problem and was about to call for service, but I decided to try this: I took the brass rings where the gas comes out and soaked them in a good bbq grill cleaner and then brushed them all off. I took a long toothpick and cleaned out each hole in the ring well. Then I put some of the bbq cleaner into the ring on the cooktop where the brass rings sit to clean out the accumulated cooking junk. I brushed them well and used a toothpick around the ignitors to clean off the junk. At first, none of them worked (cause they were still wet I think) but after careful drying and a few moments all of the burners are now working fine. Im sure this saved me a couple hundred dollars and took me an hour.

Weber Silver BBQ has 3 burners only 1 has normal flame.


you may have to remove the burners and clean the inside of them. they could have insect webs inside preventing the flow of gas. hope this helps. also, try opening the tank really slowly.

How do i light this gas grill, it is a charbroil quantum....it was borrowed from our friend, who is now not picking up the phone...


Checklist:
1-Make sure propane tank has propane in it.
2-Turn regulator (valve attached to propane tank) on.
3-Turn burner dials on, usually there is a "light" or "ignite" position to let the most gas flow to start. If there isn't, just turn it/them to high.
4-Listen for the hissing, if you hear some hissing from the grill, it has gas flow.
5-Turn the dials back off and give 3-5 minutes for gas to clear.
6-Turn dials back on and hit the igniter button.
That should do it! :)

No gas getting to bbq


I switched to the new style 20# tank with the new turn-on knob.  I couldn't get enough gas pressure to the BBQ burners for all three burners to light or to keep a strong flame on even one burner.  The new style tanks have a safety valve on the inside of the tank that shuts the gas off if you turn the knob on too fast because the safety valve thinks there is leak.  Shut everything off and then try turning the knob on real slow, especially at first, before turning it all the way on.  If that doesn't work (it didn't for me), then replace the large plastic connection valve knob (female end) that attaches the regulator to the tank.  Mine was for the old style tank and was black (low pressure).  I went to a propane company and had them replace it with a green knob (higher pressure).  Took it home and WALA!  Everything works fine now.  But it was very frustrating trying to figure why I couldn't get any gas to the burners after buying a brand new tank.  I hope this helps solve your problems.
