Abstract
The present invention relates to a combustion control device incorporated in an apparatus such as water heater and provides the combustion control device having an improved configuration with a main controller and a sub controller, capable of employing a microcomputer with lower capability as the sub controller, and ensuring higher safety than ever before. Signals indicating a combustion state of a combustion apparatus are inputted into the main controllerand the sub controllerin parallel. Upon fulfillment of a predetermined condition of stopping, the main and sub controllersandeach output a stop signal to cut off a current to be supplied to a device driving circuit. The conditions of stopping in outputting of the stop signal by the main and sub controllers are such that the sub controlleris less apt to execute the cutoff than the main controller
