Product Summary
Top Quality Aftermarket Part for Quadrafire Heatilator 812-4470

The Thermocouple is the device that monitors the fire after start-up.
Once it reaches temperature the thermocouple allows the stove to start feeding on it's own in normal operation mode.
If your stove goes out after the initial start-up cycle, more than likely the thermocouple needs to be replaced.
