FOREWORD
The AERCO Benchmark (BMK) 1500 and 2000 MBH boilers are modulating and condensing
units. They represent a true industry advance that meets the needs of today's energy and
environmental concerns. Designed for application in any closed loop hydronic system, the
Benchmark's modulating capability relates energy input directly to fluctuating system loads. The
turn down ratios for these boilers is 20:1. These BMK models provide extremely high efficiency
operation and are ideally suited for modern low temperature, as well as, conventional heating
systems.
The Benchmark Model BMK 1500 and BMK 2000 boilers operate within the following input and
output ranges:
Benchmark Model
Input Range (BTU/hr.)
Output Range (BTU/hr.)
Minimum
Maximum

1,395,000
BMK 2000
100,000
2,000,000
86,000
1,860,000
The output of the boiler is a function of the unit’s firing rate (valve position) and return water
temperature.
When installed and operated in accordance with this Instruction Manual, these boilers comply
with the NOx emission standards outlined in:
South Coast Air Quality Management District (SCAQMD), Rule 1146.2
Whether used in singular or modular arrangements, the BMK 1500 and BMK 2000 offer the
maximum venting flexibility with minimum installation space requirements. These boilers are
Category II, III and IV, positive pressure appliances. Single and/or multiple breeched units are
capable of operation in the following vent configurations:
Conventional, Vertical
Conventional, Sidewall
Conventional, Direct Vent, Vertical
Sealed, Direct Vent, Horizontal
These boilers are capable of being vented utilizing Polypropylene and AL29-4C vent systems.
The Benchmark's advanced electronics are available in several selectable modes of operation
offering the most efficient operating methods and energy management system integration.
IMPORTANT
Unless otherwise specified, all descriptions and procedures provided in this
Installation, Operation & Maintenance Manual apply to the Benchmark
series of boiler.
