Abstract

See full text

A water heater includes a combustor, a gas valve, a blower, a detector, and an operating device. The detector senses a speed of a motor of the blower. The operating device is stored with reference speed ranges under various gas supplies to control the gas valve to cut off the gas supply when the detector senses that the speed of the motor of the blower is beyond the reference speed range.
