There are three possibilities:
- First thing to check is the regulator reset. All regulators come with a safety feature to slow the release of propane gas in the event the propane tank is left on. To reset the regulator, turn everything off, including the propane tank. Unhook the regulator from the propane tank. Wait about 15 minutes. This should allow the regulator the time to reset. Then hook the regulator back up to the propane tank and slowly turn on the propane.
- A second option to try is the air gate adjustment. Each burner has an air gate to control the air to gas ratio. There is a tiny silver screw that you can loosen and a metal gate that you can slide open or losed. It is recommended to start at half closed. Once you find the setting you like you can tighten the screw and it will stay like that.
- The final option is that the regulator may be defective. If you have tried the other two options and this has not solved the issue, please contact Blackstone customer service at (435) 252-3030 ext#1.
