Turn burner control knobs to "OFF", turn off the cylinder valve and disconnect regulator from LP gas

tank.Wait approximately two minutes.
2. Reattach regulator and slowly turn cylinder valve back on. The flow limiting device will now be reset.

If this does not work either one of the venturi valves is not connected properly or your will need to just replace the lp regulator if the above reset does not work please feel free to ask any ??

Also please rate me on my help thank

There is a regulator that regulates the amount of fuel that comes from the cylinder...it sounds like the regulator may have become defective. the regulator is that round thing that is on the hose coming from the tank...they are readily available at most home improvement stores and most hardware stores
