My LP gas grill won get hotter than 250 to 300 F, even with all burners on high. Why?
Bypass Since 1995 all regulators (the part that attaches to the gas tank to regulate the flow of gas) have included a safety device that restricts the flow of gas in the event of a gas leak. This safety device can be inadvertently activated in two ways, putting the grill into what is commonly called “bypass”. The first way for the device to be activated is to leave one or more burner control knobs in the “ON” position when the LP cylinder valve is opened. The second is not to wait long enough to “start” the grill after opening the LP cylinder valve. The safety device in the regulator is activated each time that the LP cylinder valve is opened. The device resets itself when the gas pressure equalizes between the closed burner control valve and the regulator, through the hose. If a burner control knob is turned on before the gas pressure can equalize, the device will remain in “bypass”. The length of time necessary to wait to “start” the grill after turning on the LP cylinder valve is de
