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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e495,000 BTUH natural gas commercial boiler with 81 percent thermal efficiency and CSD-1 compliance\u003c\/li\u003e\n\u003cli\u003eGasketless ASME copper heat exchanger with Loch-Heat ceramic tile combustion chamber for durability and low maintenance\u003c\/li\u003e\n\u003cli\u003eBMS terminal strip, 24-volt control system, and electronic temperature control for seamless building automation integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Lochinvar 100198984 delivers dependable high-capacity heating for commercial applications with a robust copper construction, sealed combustion design, and full CSD-1 safety compliance.
