Generally speaking, a latching valve is easily installed in the path of gas flow on a gas grill. Once a grill is turned on, an automatically activated on/off switch activates a electric timing device, which begins monitoring time. The timing device is adjustable by the user to set the amount of time it will accrue prior to sending power to a latching valve, terminating the gas flow. So, if a gas grill is inadvertently left on, the latching valve will receive power and be closed, saving fuel and preventing a possible hazard. At this point a reset button on the timing device must be pressed to reopen the latching valve. But, if a gas grill is used and shut off prior to that time set by the timing device no action will result from the Gas Grill Propane Monitor.
