    • PURPOSE:To eliminate troublesomeness during test by a method wherein a test time is selected as the discharge time of an igniter during a time in which an initial ignition confirmation signal is outputted, an ordinary value is selected after output of the initial ignition confirmation signal, and a selected value is fed to an igniter discharge control means. CONSTITUTION:When a power source is turned ON and operation to generate a combustion command signal (opening of a hot water feed faucet 14 and turning ON of an additional burning switch) is carried out, a gas feed valve 13 to a pilot burner 7 is opened, and an igniter 8, simultaneously, is discharged. In this case, a discharge time in which ignition is first detected is TT and longer than an ordinary discharge time TN, and set to, for example, approximate 30 seconds. Thus, quantities of air gathering in a gas piping can be discharged through one action of ignition operation, and there is no need to repeat ignition operation through opening and closing of the hot water feed faucet 14 times to discharge air. When, after discharge of air, gas is fed and ignition is effected, next and following discharge times are switched to the ordinary discharge time TN.
