American Water Heaters AABCL3-100T275-6NOX 100 Gal 275K Btu Gas

Product Description

The American Water Heaters AABCL3-100T275-6NOX is a heavy-duty commercial gas water heater rated at 100 gallons storage capacity and 275,000 BTU/h input. Built for high-demand applications, this unit features an ultra-low NOx burner configuration, reducing nitrogen oxide emissions to meet stringent air quality standards in regulated markets. Licensed plumbers and commercial mechanical contractors typically specify and install this class of equipment in systems requiring sustained high-volume hot water delivery. The 275,000 BTU/h input rating supports rapid recovery, making it suitable for facilities that cannot tolerate long reheat cycles.

This water heater is designed for commercial installations where large storage volume and high firing rates are required. Typical applications include hotels, restaurants, laundry facilities, multi-unit residential buildings, and light industrial processes. The ultra-low NOx designation makes this unit a candidate for installations in South Coast AQMD jurisdictions and other regions with low-NOx mandates. It operates on natural gas or as specified at the time of order, and is intended for permanent, code-compliant mechanical room installation.

Compatibility

Designed as an OEM-style commercial gas water heater for high-demand hot water systems requiring 100-gallon storage and high-input gas firing in regulated low-NOx markets.

Installation Notes

Installation must be performed by a licensed plumber or mechanical contractor in accordance with local plumbing codes, the Uniform Plumbing Code (UPC) or International Plumbing Code (IPC), and applicable gas codes such as the IFGC. Shut off the gas supply and cold water inlet before beginning any service or installation work. The unit requires proper venting sized for a high-BTU commercial appliance — consult the manufacturer installation manual for flue sizing and draft requirements. Do not operate the heater without verifying that all gas connections, relief valve piping, and venting are complete and inspected.
