REFERENCE INFORMATION FOR QUALIFIED TECHNICIAN: Thermopile / Thermocouple Operation

♦Thermopile: Millivolt production should be a minimum of 325 MV with pilot only.

♦Thermocouple: Millivolt production should be a minimum of 14 MV with pilot only.

Drop out rate

♦TP 50-60 MV

♦TP 1 1/2-2 Min. (3 max.) if longer, replace thermopile.
