Precision Alignment: Centrally machined outer diameters allow for fast

while the reversible flow capability offers maximum flexibility in complex piping configurations without sacrificing pressure drop performance

Check for a weak pilot flame that isn't fully engulfing the top 1/2 inch of the thermocouple

this switch prevents operation during flue blockage or draft inducer failure

The shunt provides a continuous electrical path that bypasses the switching mechanism for one side of the line

Reznor 197033 Rollout Switch Precision Alignment: Centrally machined outerThe Reznor 197033 Rollout Switch is a critical safety component designed for high limit flame rollout detection in Reznor heater units. This manual reset rollout switch operates with a fixed temperature setpoint of 210 degrees Fahrenheit, providing essential circuit interruption if burner flames escape the combustion chamber. Engineered with a Single Pole Single Throw (SPST) configuration, this switch serves as a direct replacement for Therm O Disc
