FOREWORD
The Advanced Modular (AM) Series represents the latest in high efficiency, condensing boiler
and water heater technology. The AM Series has a unique modular design that provides
exceptional reliability, serviceability, and fuel savings from 399 to 1000 MBTU. Each unit is
comprised of between two and four independent thermal modules firing up to 250 MBTU each at
5:1 individual turndown. This allows for superior temperature control and low-cycling operation.
This unique design provides the multiple boiler redundancy required in a boiler plant, but in a
single unit installation with one set of water connections, one gas connection, and one vent
connection. When needed, multiple units are easily co-located to provide a boiler plant with
the highest efficiency, turndown, and redundancy in the smallest footprint. Multiple units are
sequenced through the AERCO AM Cascade Manager. Each unit is equipped for Modbus
communication to a BAS. High efficiencies and low vent temperatures mean the unit can be
vented in PVC, CPVC, Polypropylene, and AL29-4C vent materials. The front-access design also
means the unit is very simple to maintain and service.
