Description
The Utica-Dunkirk 14629002 is a factory-specified thermal cutoff rollout switch engineered to protect gas furnaces and boilers from hazardous flame rollout events. Calibrated to trip at 144°C (291°F), this one-time safety device monitors burner compartment temperatures and interrupts the control circuit the moment conditions exceed the rated threshold — shutting down the burner before heat can damage the heat exchanger, surrounding components, or create a fire hazard.
Designed as a direct OEM replacement for Utica-Dunkirk heating equipment, this thermal cutoff rollout switch installs quickly and restores safe, code-compliant operation. Because it is a single-use device, it must be replaced after any trip event — never bypassed or reset manually.
Key Features
- Trip temperature: 144°C (291°F)
- Single-use thermal cutoff — activates permanently upon reaching rated temperature
- Monitors burner compartment for dangerous flame rollout conditions
- Interrupts control circuit to shut down burner and prevent equipment damage
- Direct OEM replacement for compatible Utica-Dunkirk furnaces and boilers
- Must be replaced after activation — never bypass or attempt to reset
Application
- Compatible with Utica-Dunkirk gas furnaces and boilers requiring a 144°C/291°F rollout thermal cutoff
- Ideal for service technicians performing safety device inspections and replacements
Why Replace Your Thermal Cutoff Rollout Switch?
A tripped rollout switch is a signal that a potentially dangerous condition — such as a blocked heat exchanger, improper venting, or excessive burner flame — has occurred. Always diagnose and correct the root cause before installing a new thermal cutoff. Installing the correct OEM-specified replacement ensures the safety system performs as designed and keeps your equipment operating within manufacturer specifications.
