Lochinvar 100137017 Copper-fin Ii Cfn High Efficiency Natural Gas Commercial Water Heater 650000 Btu/hr

Product Description

The Lochinvar 100137017 Copper-Fin II is a high efficiency commercial natural gas water heater built for demanding applications where reliable hot water output and long service life are critical. Part of Lochinvar's CFN series, this unit delivers 650,000 Btu/hr input capacity, making it well suited for large commercial facilities such as hotels, apartment complexes, hospitals, schools, and industrial buildings. The Copper-Fin II design is one of the most recognized platforms in commercial water heating, and this model continues that legacy with a copper-finned tube heat exchanger that maximizes heat transfer while minimizing energy waste. Copper fins are bonded directly to the heat exchanger tubes, allowing efficient thermal transfer from combustion gases to the water supply. The gasketless heat exchanger design reduces long-term maintenance concerns by eliminating a common failure point found in traditional designs. Ignition is handled by a hot surface igniter, which provides reliable, pilot-free startup and reduces standby energy loss compared to standing pilot systems. The unit uses Aire-Lock direct vent technology, which draws combustion air directly from outside and exhausts flue gases through an 8 inch vent. This closed combustion setup improves safety and efficiency, particularly in tight mechanical rooms or indoor installations where indoor air quality matters. The water connection is a 2 inch NPT, which is standard for high-output commercial water heating equipment and allows straightforward integration into existing piping systems. The pump mounted configuration means the circulator pump is factory installed, simplifying installation and reducing field labor time. Lochinvar's Smart System control system is integrated into this unit, giving technicians and facility managers precise control over performance and diagnostics. This model runs on natural gas and measures 22.25 inches wide by 56.75 inches deep by 31.5 inches tall, fitting a range of mechanical room configurations. HVAC and plumbing professionals will appreciate the combination of proven copper-fin technology, multiple venting flexibility, and the smart controls package that makes commissioning and troubleshooting straightforward on the job site.
