Heil Rollout Limit Switch Manual Reset Boiler Safety Controls & Aquastats

The Heil rollout limit switch (also called a flame rollout switch or manual reset limit control) is a replacement safety control for gas-fired heating equipment. It helps protect the appliance from overheating by monitoring the burner area for abnormal flame conditions.

Key Features:

• Manual reset design: Once tripped, the switch stays open until it is reset by hand. This prevents the burner from restarting on its own until the cause of the problem has been found and corrected.
• Normally closed, temperature-activated operation: The switch opens the control circuit when it senses excess heat, which shuts down the burner.
• Burner flame monitoring: Rollout controls mount on the burner or manifold assembly. They help confirm that flames are drawn properly into the heat exchanger.
• Simple reset button: A button on the switch lets a technician restore the circuit after the problem has been fixed.
• Heil quality: Heil is a heating and cooling brand, and these controls are made as replacement safety components for Heil equipment.

A tripped rollout switch usually points to a problem such as restricted airflow, a blocked flue or a heat exchanger issue. Find and correct the cause before resetting the switch and returning the system to service. Always disconnect power before servicing, and have the work done by a qualified HVAC technician.
