PURPOSE:To enable to easily switch quantities of the gas consumption of gas heaters at both sides to each other, by a method wherein a device is used in a gas table provided with gas switches at both sides, a damper and a gas nozzle are securly or integrally mounted to a burner, and the gas nozzle detachably engages with a gas cock. CONSTITUTION:A nozzle receiver 7 is screwed in a gas cock 6, and an on-off valve 8, a valve rubber 9, a valve rubber receiver metal 10, a valve spring 11, and a seat 12 are mounted in the nozzle receiver 7. A seal rubber 13 is located in the vicinity of the inlet of the nozzle receiver 7 to seal a gas nozzle 14. The gas nozzle 14 is clamped to a damper 15 which is secured to a burner 16 by means of a screw 17. The size of a part A of the nozzle receiver 7 and the size of a part B of the gas nozzle 14 are set to be A>B, parts B, C, and D are set to be B=C+D, and thereby the parts A and C have a size relation of A>C. This permits the quantities of the gas consumption of gas heaters at both sides to be easily switched to each other. |
