Description
The International Comfort Products 522559 is a precision-engineered rollout switch designed to protect your furnace from dangerous flame rollout conditions. When burner flames roll out beyond the combustion chamber, this switch acts as a critical safety barrier — cutting power to prevent heat exchanger damage, fire hazards, and carbon monoxide risks.
How It Works
This SPST (Single-Pole, Single-Throw) rollout switch monitors the temperature near the burner assembly. If flame rollout causes the ambient temperature to rise to the open setpoint, the switch trips and interrupts the circuit. Once the unit cools down to the close setpoint, the automatic reset function restores normal operation without requiring manual intervention.
