Ao Smith 100110138 Flanged Incoloy Element 480V 15KW

Product Description

The AO SMITH 100110138 is a flanged Incoloy heating element designed for commercial electric water heaters. It operates at 480 volts and delivers 15 kilowatts of heating capacity. The element features Incoloy nickel-alloy sheathing, a material chosen for its corrosion resistance and durability in demanding water conditions. A medium watt density design reduces scale buildup and extends service life compared to high-watt-density alternatives. Strong, forged steel flanges provide a secure, leak-resistant mounting point. A gasket is included for a complete installation. Licensed commercial plumbers and water heater technicians are the typical installers for this type of element.

This element is rated for commercial water heater applications where 480-volt three-phase or single-phase power supply is present. It is engineered for use in high-demand commercial settings such as hotels, laundry facilities, foodservice operations, and other applications requiring sustained, high-output hot water production. The bolt-circle diameter is 2.5 inches and the flange pattern is compatible with both round and square flange configurations. Maximum element length is 17.5 inches, which determines the minimum tank diameter required for installation.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater service technician in accordance with local plumbing codes and the manufacturer's service documentation. Before replacing the element, shut off electrical power at the breaker panel and close the cold water supply valve, then drain sufficient water from the tank to expose the flange assembly. Verify that the replacement element voltage and kilowatt rating match the existing wiring and breaker capacity before energizing the unit. Never energize the element while the tank is empty, as dry-fire will cause immediate and irreversible damage.
