PURPOSE:To make it possible to easily determine the mounting positions of an ignition plug and a thermocopule by providing a plurality of projections on the outer peripheral side surface of a burner head, providing holes in respective projections, and the holes of respective projections the ignition plug and the thermocouple are inserted, which are provided upright in the apparatus main body to connect the burner head to a mixing pipe in an attachable and detachable manner. CONSTITUTION:Projections 35, 36 and 37 project radially from the outer peripheral side surface of a burner head 21 of an auxiliary burner A at an equal interval of 120 deg., and concurrently serve as spacers so as to appropriately hold a gap 29 formed between the burner head 24 of a master burner B and the burner head 21 of the auxiliary burner A. Respective projections 35-37 are provided with holes 40 having a caliber through which the ignition plug 38 and the thermocouple 39 can be inserted. When the ignition plug 38 and the thermocouple 39 are fixed perpendicularly to the apparatus main body, and are fitted into respective holes 40, the burner head 21 is positioned on the central axis of the master burner B, and is located so as to be fitted into a mixing pipe 20. The lateral and longitudinal positions of the burner head 21 are located respectively so that the ignition and generation of electromotive force can be conducted adequately. |
