Description

The Johnson Controls K16RA-48H Coaxial Thermocouple is a component that produces a millivolt signal when it detects the heat at the point where two different metals are joined. The signal output varies between 20 and 30 millivolts depending on the temperature of the flame, to signal the safety control that the flame is present. This thermocouple is mounted at the burner assembly, the sensing tip is placed directly in the flame, and the threaded capillary is attached to the mounting bracket. It has a 48-inch coaxial lead, thick capillary construction, and an 11/32-32 threaded connection.

Step1: Shut off gas supply and allow unit to cool completely.

Step2: Disconnect old thermocouple from pilot and control valve.

Step3: Clean pilot assembly area before installing new unit.

Step4: Position new thermocouple tip directly in pilot flame.

Step5: Thread connector into valve and tighten lightly.

Step6: Route tubing away from heat sources and sharp edges.

Step7: Restore gas and test for stable pilot operation.
