• Not ASME rated

Compatibility & Requirements

This water heater requires a dedicated 277-volt single-phase electrical supply and installation by a qualified professional. The unit is not approved for residential applications. Plumbing connections, electrical wiring, temperature and pressure relief valve, and expansion tank must be purchased separately. Installation must comply with all local electrical and plumbing codes. Confirm available electrical service matches the 277V 1PH specification before ordering. The 24-inch diameter and 60.5-inch height require adequate clearance for service access. Voltage conversion kits are available separately to adapt the unit for 240V or 208V operation if needed. This item replaces LTE-80D-CUSTOM, LTE-80D-5.5KW-240V, and LTE-80D-208.

Installation & Care

Install the water heater on a level surface capable of supporting 175 pounds plus the weight of water. Connect cold water inlet and hot water outlet using appropriate dielectric unions to prevent galvanic corrosion. Install a properly sized temperature and pressure relief valve and route discharge piping per code. Wire the unit to a dedicated 277V circuit using wire gauge appropriate for 12.2 kW load. Fill the tank completely and purge air before energizing. Set the thermostat to the desired temperature between 120º and 181ºF. Drain the tank periodically through the brass drain valve to remove sediment. Inspect the anode rod annually and replace when significantly depleted. Test the temperature and pressure relief valve monthly to ensure proper operation.

What's Included

• 80-gallon electric water heater tank with dual heating elements
• Adjustable thermostat with manual reset high temperature cutoff
• CoreGard anode rods with stainless steel core
• Commercial-grade brass drain valve

Warranty & Support

This water heater includes a 6-year limited warranty on the tank and a 1-year limited warranty on parts.

Frequently Asked Questions

Q: What voltage conversion options are available for this water heater?
A: Separate conversion kits allow the LTE-80D to operate at 240V or 208V instead of the standard 277V configuration, providing flexibility for different commercial electrical systems.

Q: How quickly does the 80-gallon tank heat water with the dual 6100-watt elements?
A: With 12.2 kW total heating power, hot water is achieved in approximately 20 minutes from a cold start, though actual recovery time varies based on incoming water temperature and usage patterns.
