Lochinvar 100198984 Copper-fin Commercial Gas Boiler 495000 Btuh Natural Gas CSD-1 CBN0497-M13

Product Description

The Lochinvar 100198984 is a commercial copper-fin gas boiler rated at 495,000 BTUH for natural gas applications. It is designed for heavy-duty commercial heating systems and meets CSD-1 safety requirements along with ASME, AHRI, and CSA standards. This boiler is built around a gasketless copper heat exchanger that provides reliable heat transfer and simplified maintenance for HVAC professionals. The unit delivers 81 percent thermal efficiency using a fan-assisted sealed combustion chamber, which reduces heat loss and improves fuel economy in high-demand building environments. The GE GAP/FM/CSD-1 firing system ensures precise, safe ignition and operation across a wide range of commercial settings including schools, hospitals, apartment buildings, and industrial facilities. The natural gas connection is 1-1/4 inches and the venting connection is 6 inches, making installation straightforward in standard commercial mechanical rooms. The boiler operates at up to 160 PSI and includes a 50 PSI ASME pressure relief valve for system protection. A hot surface ignition system provides reliable startup without the need for a standing pilot. Electronic temperature control and an adjustable high limit with manual reset give technicians precise management of operating conditions. The 24-volt control system is compatible with building management systems through a dedicated BMS terminal strip, making integration into modern building automation setups simple. A pump relay with delay protects the pump and ensures proper system sequencing. Additional features include a referenced gas valve, downstream test valve, flow switch, combustion air filter, temperature and pressure gauge, and built-in freeze protection. The Loch-Heat ceramic tile combustion chamber withstands high temperatures and extends service life. Water content is 1.7 gallons and the boiler dimensions are 45-1/4 inches wide by 22-1/4 inches deep by 31-1/2 inches tall. A 10-year limited warranty backs this unit for long-term commercial use.
