FOREWORD

Foreword
The AERCO KC boiler is 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 load
tracking capability relates energy input directly to fluctuating system loads through a 14:1
modulating turndown ratio. The boiler’s condensing capability offers extremely high efficiencies
and makes the KC boiler ideally suited for modern low temperature, as well as, conventional
heating systems.
The KC boiler can be used singular or in modular arrangements for inherent standby with
minimum space requirements. Venting capabilities offer maximum flexibility and allow
installation without normal restrictions. The advanced electronics of each boiler module offer
selectable modes of operation and interface capabilities.
After prolonged shutdown, it is recommended that the startup procedures in Section 4 and test
procedures in Section 6 of this manual be performed, to verify system operating parameters. If
there is an emergency, turn off the electrical power supply to the Aerco boiler or close the
manual gas valve located before the unit. The installer is to identify the emergency shut-off
device. FOR SERVICE OR PARTS, contact your local sales representative or AERCO
INTERNATIONAL.
