摘要

The apparatus for gas heater having two small/big main burners, prevents blast combustion on ignition starting. The apparatus comprises a igniting means (10) arranged near small main-burner (3) and operating by starting switch (12) for a certain time; function setting means (8) returned to previous state by the switch (12); electromagnetic valve (31) provided for opening/closing gas circuit of the burner (3) and operating by an output terminal of three terminals (81),(82),(83) in the means (8); first timer (6) operating when the second terminal (82) is set on the means (8); second timer (7) operating when one of terminals (82),(83) is set; electromagnetic valve (21) for opening/closing big main-burner (2). The valve (31) delays the valve opening by output of the timer (6) and the setting time of the timer (6) is longer than that of the second timer (7).
