ムロツド７を設け、該フレームロツドの検出電流
値のうち、着火時の値と燃焼中の値を比較し、両
者の差が予め設定しておいた値より大きいとき、
フレームロツドの絶縁状態が不良である旨の信号
を発する判定器１３を備えたことを特徴とするフ
レームロツドの絶縁不良検出装置。 A flame rod 7 is provided in the burner 2 to detect the presence or absence of a flame, and among the current values detected by the flame rod, the value at the time of ignition and the value during combustion are compared, and the difference between the two is determined from a preset value. When it's big,
An insulation defect detection device for a frame rod, comprising a determiner 13 that issues a signal indicating that the insulation condition of the frame rod is defective.
