To provide a gas appliance discriminating device with which it is possible to discriminate a gas appliance, as well as identify a more specific type of the discriminated gas appliance.SOLUTION: When, in an initial discrimination period that includes a period from when gas appliances 11, 12, 13 start operating till when they stabilize due to an increase in a gas flow rate, a difference value between the previous and the latest flow rate data satisfies a prescribed discrimination condition, the appliance discrimination means 104 of a gas appliance discriminating device 100 discriminates that a gas appliance in operation is or can be specific gas appliances 11, 12, 13; when a change of flow rate data in the initial discrimination period satisfies a prescribed monitoring continuance condition, the appliance discrimination means 104 continues monitoring a change of gas flow rate data, even in a monitoring continuance period that is set as a prescribed period after the initial discrimination period, in order to identify a more specific type of the gas appliance in operation.SELECTED DRAWING: Figure 1 【課題】ガス器具の判別を可能とするとともに、判別したガス器具のより具体的な種類を識別することを可能とする、ガス器具判別装置を提供する。【解決手段】ガス器具判別装置１００の器具判別手段１０４は、ガス器具１１，１２，１３が稼働を開始してからガス流量が増加して安定化するまでの期間を含む、初期判別期間において、前回および今回の流量データの差分値が所定の判別条件を満たす場合には、稼働中のガス器具が、特定のガス器具１１，１２，１３またはその可能性があると判別するとともに、初期判別期間における流量データの変化が所定の監視継続条件を満たす場合には、稼働中のガス器具のより具体的な種類を識別するために、初期判別期間の経過後の所定期間として設定される監視継続期間においても、継続して流量データの変化を監視する。【選択図】図１
