PURPOSE:To elevate operability of fire control after ignition of a burner by providing an ignition lever to actuate an igniter so that it may freely make a sliding motion to right & left directions simultaneously with the supply of gas to the burner by depressing operation, and by an opening and closing operation of a valve means to control the supply amount of gas to the burner by its operation of sliding motion. CONSTITUTION:In case of ignition operation of a burner 6, an ignition lever 16 is depressed into operation until a valve 2' of an electromagnetic valve 2 is set in the opening position by a valve stem 9, and then a main valve hole 11 and a pilot flow route 10 can be opened so that the gas may be provided to a burner 6 and a pilot burner 35. At the same time, a micro-switch 37 is put in ON-operation by a drive plate 20, and an ignition plug 36 is discharged, then the burner 35 and the burner 6 are ignited to carry out combustion. In case of changing a heating power of the burner 6, an adjusting valve 28 is moved up and down at an adjusting part 33 of an adjusting lever 30 and the amount of gas provided to the burner 6 is adjusted by performing a sliding operation of the ignition lever 16 to right and left at the ignition position of the burner 6. Namely, when the ignition lever 16 is put in a sliding operation to the right side, the adjusting valve 28 goes down by the action of taper of the adjusting part 33 to throttle an adjusting valve hole 32. Reversely, when the lever 16 is put in a sliding operation to the left side, the adjusting valve 28 goes up to open the adjusting valve 32. |
