My Weber Spirit grill produces insufficient flame after it rains.

Turn off propane. Disconnect propane tank from barbecue. Open burner valves for about 20 seconds. Close valves. Reattach propane tank. Slowly open propane tank valve. Turn on burner and ignite

Clean out the burners and the injectors on the gas line to each burner .

Check for blocked orfice on burner or blockage in the burner

If you want to totally dismantle it, here's a link to the assembly manual for your model grill. I would think that just remove the grill, side burner shelf and the other side shelf would suffice. if you remove the grill grates and flame tamers. In other words anything that's loose in side the grill. If you want to dismantle it all piece by piece, you the link and do everything in reverse.

Good luck. I hope this helps you. Please let me know. Thanks

Hi, Patty. The low burner flame on a natural gas grill an be caused by several things.

1. The gas line shutoff valve is not fully open.
2. The burners are clogged and need to be removed and properly cleaned
3. The venturi valve(s), which has spider screens may be clogged.

The things listed above are the top 3 reasons for the low burner flame problem on a Natural Gas Grill.

To help you accomplish the cleaning of the burners and the venturi valves, I have included a link to your Owners Manual, that you can download & print for future reference. It has detailed instructions and diagrams in the Maintenance section, that will show you how to accomplish this.

Hope this helps you to solve the problem. Please let me know. Thanks and Happy Grilling!!

Hello,
Either the cleaner you used is partially clogging the burner holes or you inadvertently moved the air adjustment and are starving it from getting the air it needs to burn properly. Douglas

Try replacing the regulator and hose, easy to do and not very expensive. If this doesn't work, please let me know.

clean the burners and the oriffice , try this then check the reg

The regulator that comes with Weber grills shuts the gas flow off if it detects the slightest leak. Disconnect the tank an reconnect. Check connections with soapy water for any leaks. Another problem, though uncommon for a new grill is a defective regulator. You have a 1 year warrenty on your grill so contact Weber if you continue to have problems.

Try replacing the regulator.
