FOREWORD
The AERCO Benchmark (BMK) 750 through 6000 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. Designed for application in any closed loop
hydronic system, the Benchmark's modulating capability relates energy input directly to
fluctuating system loads. These BMK 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 descriptions in this document apply to the Benchmark Platinum Series of boiler.
•
All measurements apply to both natural gas and propane models.
The Benchmark models operate within the input and output ranges listed below.

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 BMK750
– 2000
and 5000 & 6000 comply with the NO
x
emission standards outlined in:
South Coast Air Quality
Management District (SCAQMD), Rule 1146.2
. In addition, the BMK2500
– 6000 comply with
the
Bay Area Air Quality Management District regulation 9, Rule 7
.
