When ever we get a full 20 lb. tank of lp gas, our 3 burner weber grill has a very low flame and it goes out frequently with low heat until it runs for a long time, then it runs normal.

IS PROPANE TANK RESIGNED TO BE MOUNTED VERTICAL OR HORIZONTAL? The Outflow tube of the vertically mounted tank runs to within an inch of the bottom of the tank. The horizontally mounted Tank Design has an outflow tube that has a 90 degree bend half way down to 1" of the side of the tank if it mounted in the wrong orientation for it's design, it stops picking up LPG halfway down. When used in it's proper application, the orientation would be correct for gas pickup. A tank designed for horizontal mounting used in a verticle position picks up LPG for half of the tank, then it will light (because of the fumes are flammable) but do not posses the density to heat. (Too much Air) in the mixture fuel to air ratio. We found this out after pulling the shut off valve off of a tank with same problem. It was a horzontal tank used in a verticle positiuon. It worked for half a tank of fuel.

Whether you're using a 20 Lb Propane Grill Tank or a screw in gas canister, the solution to the problem is the same .

1. Be sure you have enough gas in the tank or canister to maintain proper ignition.

2, If the above checks out OK. Turn the LP tank valve OFF or if you're using a screw-on canister
turn the gas valve OFF.

3. Disconnect the hose from the tank or unscrew and remove the gas canister.

4. Wait 5 minutes and reconnect the hose to the tank or reattach the canister to the gas valve.

5. Open the gas valve VERY, VERY SLOWLY (Slow Motion, slow). Once the valve is full open, light
the burner & turn it to HIGH. Did the burner light and does the flame height look correct?
If so, you solved the problem. Remember to always open the tank valve Very, Very Slowly.

if the above didn't solve the problem, you will either need to replace the Hose/Regulator Assembly or the Gas Valve/ Canister Holder. The Hose/Regulator Assembly you can pickup from any home center or hardware store that sell grills & accessories for about $30.00. If it's the Gas Valve/Canister Holder, you will have to purchase that from Weber or from Factory Appliance Parts http://www.appliancefactoryparts.com/gasgrillparts/brands/weber/q200.html Part # WEB4195 ($29.99) The adapter hose is also available there if you want to make it a one stop shop for $32.99

I hope ths helped you and thanks for choosing FixYa. Happy Grilling!!

Hi,
You problem could be or probably is with the regulator...not enough gaspressure...

Propane, LP, or Natural Gas Regulator Problems
heatman101

hello. Actually I think you are probably dealing with a new issue related to the newer safety device on the 20 pound tanks. Turn off the tank and unscrew it from the grill hose. Then screw it back on and s-l-o-w-l-y open up the valve. Then light the grill.
You should notice a markedly bigger flame now. Enjoy! J.

chech the reg is giving right pressure

You probably have regulator problems.

Hello. Are you frustrated because your gas grill doesn't get hot enough lately. The problem you are having indicates that you have to go through a procedure called "RESETTING THE REGULATOR". Follow these easy steps:

1. Turn the burners on for one full minute and then off.

2. Next, remove the regulator and the hose from the tank.

3. Then reconnect the tank to the regulator and hose.

4. And very slowly open the tank.

5. Last step is to fire up the burners and start cooking with you new hot flame.

The problem began the first time you opened the valve on the tank too quickly. In the future, always turn the tank valve on s-l-o-w-l-y to prevent this problem.. Joe

Bypass valve need reset. All grills made after 1996 have this valve.

• Close the LP tank valve
• Turn all burner control knobs to the OFF position
• Open the grill lid
• Turn the LP tank valve until it is completely open
• Wait 90 seconds
• Turn the front burner to the HI/Start position
• Press the igniter until the burner is lit.
• Turn remaining burners to High
• Close the lid.
• The grill should preheat to 500-550 degrees in 10-15 minutes

I called Weber and a rep walk me through it.

Hi Lyon,
Yeah, it's the regulator. Fortunately, they're cheap and easy to replace!

You can look on line for part number 80012. Or you can remove yours and take it to Home Depot or Lowe's in the outdoor cooking area and match up a replacement. <--- they're all the same... just make sure the compression fitting (the brass end) is the same size.

The only other thing I could recommend is this... Turn the LP bottle completely off. Then completely remove the big plastic knurled knob from the tank. Now replace the knob back onto the tank (all the way and make sure it's tight). Then S L O W L Y turn the gas back on. Now try your pit. If you get the same flame, it's the regulator. If you get full flame, you just reset the safety device inside the tank.

I'm betting regulator. Good luck and happy cookin'!

The only way you can fix the low flame, low heat problem, is to remove the grill, take a medium sized paper-clip (staightened out) and clean out each individual hole on the steel burner, flame tube. (I'm sure there's a technical name for it).

Since they (the holes on the flame tube) face up unprotected, directly under the grill cooking surface they tend to get blocked quickly with continous use and certain foods, like pork ribs. Bad design unless all you plan on grilling is hot dogs.

There are about 500 individual holes, so plan on being there a while. Or in other words, do it close to the cooler.

I've been tempted to toss the thing into the woods a bunch of times over the past 2 years I've owned the dumb thing.

Good luck!
