FOREWORD
The
PVI Centurion
modulating and condensing water heater represents a true industry
advance to meet the needs of today's energy and environmental concerns. Designed for use
with natural gas or propane gas in any closed loop hydronic system, the
Centurion’s modulating
capability relates energy input directly to fluctuating system loads. Centurion models provide
extremely high efficiency operation and are ideally suited for modern low temperature, as well
as conventional, water heating systems.
