Low flame or won't get hot

Reset the flow limiter

The manual: the regulator's flow limiter cuts the gas to a trickle if it senses a leak. It also trips if a knob was on, or the valve was opened fast, when the gas came on. Weber's reset:

1. Turn every knob off.
2. Close the cylinder valve.
3. Wait 5 minutes.
4. Open the valve slowly. US: wait 60 seconds before you touch a knob.
5. Light the burners one at a time.
6. Still low: the cylinder may be nearly empty, the hose kinked, or the ports or spider screens blocked.
