The A.O. SMITH 100110096 is a high limit kit with stainless steel construction, designed to protect water heating systems from overtemperature conditions. High limit controls monitor water temperature and interrupt the heating circuit when a preset threshold is exceeded, preventing damage to the tank, heating elements, and connected piping. This kit is intended for installation by licensed plumbers and water heater service technicians working on residential or light commercial water heating equipment.
This high limit kit is suited for use in applications where overtemperature protection is required on water heating systems. Stainless steel construction provides durability in wet environments and resistance to corrosion common in water heater service conditions. It is appropriate for use in new installations as well as replacement service work on existing systems requiring high limit component renewal.
Designed as an OEM-style replacement high limit kit for A.O. SMITH water heating equipment. Verify compatibility with your specific model and serial number before installation.
Installation should be performed by a licensed plumber or qualified water heater service technician. Before servicing, shut off the electrical supply to the water heater and close the cold water supply valve to relieve system pressure where applicable. Follow all applicable local plumbing codes and manufacturer service documentation when replacing high limit components. Do not restore power until all connections are verified secure and the access panel is reinstalled.
