counter-clockwise rotation decreases it

System Protection: Acts as a high-limit cutout to protect internal heat exchangers and venting structures

Its CCW (Counter-Clockwise) Lead End Rotation is critical for ensuring the blower assembly maintains proper static pressure and airflow delivery throughout the ductwork

Precise Thermal Sensing: 3-inch probe provides accurate temperature detection within the airstream for immediate fan activation

Lochinvar & A.O. Smith 100281571 Thermopile Assembly 328140-751 counter-clockwise rotation decreases itWhen you're dealing with a pilot that won't stay lit or a gas valve that refuses to engage on a Lochinvar or A. O. Smith unit, the 100281571 Thermopile Assembly is the critical millivolt replacement part you need. This OEM thermopile is engineered to convert thermal energy from the pilot flame into a precise electrical signal, typically around 750 millivolts, to power the electromagnetic coil within the gas control valve. It is a vital component for
