Tip & How-To about Grilling

Low Flame coming out the the burners

Here are a list of reason why you may have a low flame coming out of your burner.

1. Is your tank filled with gas (have to add this as sometimes we do not realize). Place your tank on a household scale and weigh your tank. Look at the collar of the tank and stayed on the collar is a weight of the tank. Subtract the weight from the household scale from the weight of the tan and that is how many lbs left in the tank. A full tank will have approx 17-18 lbs of gas.

2. You could have a spider or other insect in your burner. Having a venturi tube cleaner is a must have accessory to effectively rid the burner tubes of any insects (or even debris).

3. Your regulator could be bad. Try replacing your regulator.

4. The office on the end of your valve could be clogged. Be sure grill and gas are off AND the grill is cool. Remove the cooking grates, heat plates and burners. At the end of the valve is a threaded orifice. Unscrew the orifice and be sure that there is no grease clogging the hole. If there is you will need a really thin drill bit to clean or if you have an air blower.

5. Your OPD valve may have "checked." This is a safety measure that stops the flow of gas to a very minimal amount. In order to reset the gas line you need to turn all your grill knobs to the off position. Shut off the gas. Remove the regulator off the tank. Open the grill knobs. Allow any remaining gas to bleed out of the line. Leave the knobs open for a minute or two. Turn your grill knobs off. Reconnect the regulator to the tank. Crack the LP tank valve and slowly open the valve allowing the gas line to pressurize. Try restarting your grill.

model #14116670 bq grill low (and sometimes no flame).Sometimes 2 out 4 burners work well

The problem you're having is the result of the OPD (Overfill Protection Device) Vale in the grill tank.
This occurs when the gas tank valve is opened to fast. Or the tank is low on gas.

To solve this problem, first be sure you have adequate gas in the tank. If that checks out OK, do the following:

1. Turn the gas tank valve OFF and disconnect the hose from the tank.

2. Wait 5 minutes and reconnect the hose to the tank.

3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

4. Once the tank valve is fully open, light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the exact same way. Do all the burner flames look correct? If so, you
solved the problem. Remember, to always open the tank valve Very, Very Slowly.

If that didn't solve the problem, you will need to replace the grill's Hose/Regulator Assembly. It runs about $30.00 at any home center or hardware store that sells grills & accessories. If you replace it, turn the tank valve ON Very, Very Slowly.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling!!

low flame at burner. I've put a new tank on my grill and now the flame stays very low on all burners. I've heard that there can be some pressure problems with a newly filled tank. Is there a quick fix?

Mike, there can be some pressure problems, but it's not the new tank. However, it does cause the problem and here's how you resolve it.

1. Turn the gas tank valve OFF.
2. Disconnect the hose from the tank and wait 5 minutes.
3. Reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow).
4. Once the valve is fully open, light the burner farthest from the tank first and turn the burn to HIGH.
Does the burner light and the flame height look correct? If so, light the remaining burners the same
way. Now, do all the burner flames look as the should? If co, you solved the problem. Always
remember to turn the tank valve ON very, very slowly>

If the above did not solve the problem, you will need to replace the grill's Hose/Regulator Assembly. You can pick one up at any home center or hardware store that sells gas grills and accessories. It will run you about $30.00 (+/-) .

Hope this helped you to solve the problem Please let me know & Happy Grilling!!

Gas not coming out enough; flame not catching on to other burners

Problem: Low flames on grill, tank is full.

Cause: These newer tanks have a device inside that limits the flow of gas to prevent leaking or accidental discharge of gas from the cylinder. The leak detector mechanism inside the tank shuts off the gas whenever the valve is opened rapidly.

Close the tank valve and remove the tank. Check the gas line for ANY object that could cause blockage. Open all valves on the grill to eliminate any pressure whatsoever. Close all valves and reattach tank. SLOWLY open the tank not over 2 turns. Check for leaks. I just open my tank a tiny bit but that is just me.

This late model gas grill service manual has more details on page 13.

gas grill

Probably 1 of 3 things:
Check your LP tank valve at an LP filling station. Make sure both valve and tank are in working order.
Next check for webs or cocoons up around where knob valves go into burners. You may have to remove burners to see into back of valves. Then swab orifice holes with a torch tip cleaner.
Third, a Menards , LP outfitter/station, or grill shop should have a universal replacement rubber gas line and "regulator"(possibly plugged or stuck shut). Sometimes you end up with cheap/bad regulator out of the factory.
Good luck and hope one these helps or does the trick.
