A method of detecting the condition of a flame includes monitoring an emf generated by the flame, which emf is indicative of the condition of the flame. An electrically isolated electrical conductor (17, 39, 9'') may be utilized to monitor this emf. The conductor is conveniently in electrical contact with the flame. A furnace assembly adapted to incorporate the method includes a housing (12) forming a combustion chamber (14) and means (16) defining a flame position in the chamber. Insulation elements (35, 37, 40) electrically isolate the conductor (17, 39, 9''). |
