FOREWORD
The AERCO Benchmark (BMK) 6000 MBH Boiler is a modulating and condensing unit. It
represents a true industry advancement 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
maximum turn down ratio for the BMK 6000 is 15:1. This BMK model provides extremely high
efficiency and makes it ideally suited for modern low temperature, as well as, conventional
heating systems.
The Benchmark Model BMK 6000 operates within the following input and output ranges:
Benchmark Model
Input Range (BTU/hr.) Output Range (BTU/hr.)
Minimum Maximum Minimum Maximum
BMK 6000 400,000 6,000,000 372,000 5,580,000
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, the BMK 6000 MBH
Boiler complies 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 6000 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 6000
MBH boiler.
