IRI Gas Train - Incorporates two safety shut-off valves in a single valve body with normally open vent valve.

Electrical Power - 220V 1-Phase, 230V 3-Phase or 460V 3-Phase

Reduced NOx Levels - AERCO recommended calibration points can be re-set to support applications that require reduced NOx emissions levels of <15ppm. However, the unit's input rate, performance efficiency and venting requirements will change. Please consult the factory for assistance balancing your efficiency and environmental requirements.

Low Gas Pressure - For applications where the maximum available gas pressure is only 4" W.C., a de-rated configuration of the product is available at 1,750,000 BTU/hr.

Secondary Low Water Cut-Off (LWCO) - where required by building code. Secondary LWCO must be installed external to boiler.

AERCO C-More™ Control Package - Standard controller supports constant set point, remote set point and/or outdoor reset schedule for individual boiler operation. Offers step-by-step diagnostic menus and status displays to help users set controls and check faults. More than 40 distinct messages, written in easy-to-understand language, convey subsystem status throughout the start-up sequence and during operation. The flash-upgradeable platform can be remotely monitored, controlled and upgraded via Modbus protocol using the RS-232 or RS-485 connection . The system provides failsafe and independent operation in the event of external building control system failures.

Communications Gateway - optional accessory supports boiler or BMS integration with BACnet, LonWorks and N2 systems.

AERCO BMS - optional multiple unit controller recommended for installations of two or more boilers to maximize operating efficiency.
