FOREWORD
The AERCO Benchmark 6000 Dual Fuel (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 this model is 15:1. This model provides extremely high
efficiency and makes it ideally suited for modern low temperature, as well as, conventional
heating systems.
The Benchmark 6000 operates within the following input and output ranges:
Input Range (BTU/hr.) Output Range (BTU/hr.)
Minimum Maximum Minimum Maximum
400,000 6,000,000 372,000 5,670,000
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 Benchmark 6000
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 Benchmark 6000 offers 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.
