FOREWORD

The AERCO Benchmark (BMK) 750, 1000, 1500, 2000, 2500, and 3000 natural gas and
propane fueled boilers are modulating and condensing units. They represent a true industry
advance that meets the needs of today's energy and environmental concerns. All these models,
under standard calibration, meet 20 parts per million (ppm) NOx requirements, and the
Benchmark 750 through 2000 are capable of complying with the U.S.'s most stringent NOx
requirements of 9 ppm.
Designed for application in any closed loop hydronic system, the Benchmark's modulating
capability relates energy input directly to fluctuating system loads. These Benchmark models
provide extremely high efficiency operation and are ideally suited for modern low temperature,
as well as, conventional heating systems.
IMPORTANT!
Unless otherwise specified, all measurements apply to both natural gas and propane models.
Benchmark models operate within the following input and output ranges:
Benchmark Boiler Intake and Output Ranges
INPUT RANGE (BTU/HR.)
MODEL
MINIMUM
BMK 750 50,000 (14.6 kW)
BMK 1000 50,000 (14.6 kW)
BMK 1500 75,000 (22 kW)
BMK 2000 100,000 (29.3 kW)
BMK 2500 167,000 (48.9 kW)
BMK 3000 200,000 (58.6 kW)
The output of the boiler is a function of the unit's firing rate (valve position) and return water
temperature.
Whether used in singular or modular arrangements, the BMK boilers offer the maximum venting
flexibility with minimum installation space requirements. These boilers are Category II and IV,
positive pressure appliances. Single and/or multiple breeched units are capable of operation in
the following vent configurations:
• Room Combustion Air:
o Vertical Discharge
o Horizontal Discharge
• Ducted Combustion Air:
o Vertical Discharge
o Horizontal Discharge
These boilers are capable of being vented utilizing Polypropylene and AL29-4C vent systems. In
addition, the BMK 750 & 1000 models are also approved for PVC and CPVC, 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.
