Foreword
The AERCO Benchmark 1.5LN Boiler is a modulating unit. It represents 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 Benchmark 1.5, with its 20:1 turn down ratio and
condensing capability, provides extremely high efficiencies and makes it ideally suited for
modern low temperature, as well as, conventional heating systems.
The Benchmark 1.5 operates at inputs ranging from 75,000 BTU/hr. to 1,500,000 BTU/hr. The
output of the boiler is a function of the unit’s firing rate and return water temperature. Output
ranges from 74,250 BTU/hr. to 1,450,000 BTU/hr., depending on operating conditions.
When installed and operated in accordance with this Instruction Manual, the Benchmark 1.5
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 1.5 offers the maximum
flexibility in venting with minimum installation space requirements. The Benchmark's advanced
electronics are available in several selectable modes of operation offering the most efficient
operating methods and energy management system integration.
