PURPOSE:To make it possible to perform confirmations such as ignition combustion, misfiring and the like, as well as the confirmations that the temperature of hot water to be supplied is precisely raised and the hot water supply is precisely carried out, thus making it possible to carry out a highly reliable monitor confirmation by controlling a monitor signal when the detector is operated by two signals for detection of combustion and detection of the temperature of water. CONSTITUTION:The monitor signal detector comprises a combustion detecting element 1 and a combustion detection circuit 2 for detecting a combustion flame, and a water temperature detecting element 3 and a water temperature detection circuit 4 which are provided in the passage of a hot water supply pipeline. The control of a monitor signal is conducted by the detection signals emitted from both detection circuits 2 and 4. Accordingly, when a telecontrol operation of a combustion hot water supplier is carried out, a combustion detection signal is outputted from a combustion detection circuit 2 by the ignition of the combustion hot water supplier, and a water temperature detection signal is outputted from the water temperature detection circuit 4 by the rise in the temperature of water within a hot water pipeline. The monitor signal is not turned ON until both signal are outputted, whereby the precise ignition and hot water supply states can be confirmed and highly reliable monitor confirmation can be made.
