Abstract
A combustion controlling system according to the present invention provides a signal path for transmitting an ignition preparation signal SA output from a master device to a transmission line through cascade-connected slave devices. Then, each of the slave devices determines whether each of the slave devices outputs the ignition preparation signal to a subsequent device, or not, based on whether there is a flame of the corresponding burner, or not, at the time of igniting the burners, and the master device opens a safety shutoff valve on the condition that an ignition preparation signal SAo has been input from the transmission line.
