<P>PROBLEM TO BE SOLVED: To provide a gas water hater capable of effectively preventing a failure in the ignition of a gas burner by preventing an insect prevention cover itself from disturbing air taken into a burner tube even if it is used for a long period of time, in the gas water heater wherein the gas burner comprises an injection nozzle for injecting a fuel gas supplied from gas piping, the burner tube for taking the fuel gas injected from the injection nozzle from a gas inlet with air and for releasing it as a mixed gas from a burner port, and the insect prevention cover covering the gas inlet, in the gas water heater wherein the combustion exhaust gas generated at the gas burner is allowed to exchange heat with water in a heat exchanger to supply hot water. Ž<P>SOLUTION: The insect prevention cover can be displaced and moved between a closing state for covering the gas inlet and an opening state not covering the gas inlet, and an opening motion for displacing and moving the insect prevention cover from the closing state to the opening state is executed in interlocking with a hot water supply permitting operation by a device operating section.
