The Superhot Boiler Draft Hood Switch is a vital safety component designed for gas-fired heating systems. This manual reset flame rollout switch acts as a thermal safeguard, monitoring the temperature near the boiler's draft hood or burner assembly. If the system detects improper venting or excessive heat buildup, the switch trips at 190 degrees Fahrenheit to shut down the heating cycle, preventing the escape of dangerous flue gases or potential fire hazards. As a critical limit control, this part ensures your residential or commercial boiler operates within safe temperature parameters. The manual reset feature provides an added layer of security, requiring a manual inspection of the venting system before the appliance can be returned to service.
