If the flame on your Blackstone griddle is low, or is not producing the heat that you'd expect you can try the suggested troubleshooting below for your type of griddle.
Griddles with regulators that connect to bulk (20 pound) tanks:
Most likely there isn't anything wrong with your griddle, it's just that the safety system in your regulator has been tripped because a high pressure of propane went through your regulator, and a reset is required.
United States regulations require that all griddle regulators contain a flow limiting device for consumer safety. This device measures the amount of propane going through the regulator to ensure the levels are safe. If the flow rate through the regulator is too high (a symptom of a large leak), the flow limiting device will trigger, restricting the flow of propane to reduce the chance of a dangerous fire. This safety system can accidentally be tripped by opening a propane tank too quickly, especially with a full tank, or opening the propane tank when a burner knob is not in the off position.
To fix that, please complete a regulator reset. Just a few things to keep in mind when completing a reset is that you want to open your propane tank incredibly slowly, as that will keep the pressure low. We recommend taking about 30 seconds to turn it 1/4 of the way, then pause for a few heartbeats and turn it another 1/4 of a turn. You shouldn't need to open your propane tank more than 1/2 of a turn.
