SAFETY INFORMATION
It is the responsibility of the installer to ensure the installation complies with all national and
local building codes and standards, in addition to the instructions outlined in this manual. All
applicable codes take precedence over any instructions made in this document.
This symbol indicates safety alerts. When you see this symbol on labels or in this
manual, be alert to the potential for personal injury. Understand and pay
particular attention to the signal words DANGER, WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which if not avoided, will result
in death or serious injury.
WARNING indicates a potentially hazardous situation, which if not avoided, could
result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which if not avoided, may result
in minor or moderate injury. It is also used to alert against unsafe practices and
hazards involving only property damage.
WARNING - Improper installation may create a condition where the operation of
the product could cause personal injury or property damage. Only a qualified
contractor, installer or service agency should install this product. Improper
installation, adjustment, alteration, service or maintenance can cause injury or
property damage. Refer to this manual for assistance.
CAUTION - This product must be installed in strict compliance with the installation
instructions and any applicable local, state, and national codes including, but not
limited to; building, electrical, and mechanical codes.
WARNING - FIRE OR ELECTRICAL HAZARD. Failure to follow the safety warnings
exactly could result in serious injury, death, or property damage. A fire or electrical
hazard may result causing property damage, personal injury or loss of life.
WARNING - Hot water from a boiler used to satisfy heating requirements can be
heated to temperatures of 180°F. Parts containing water this hot can scald very
quickly. Use extreme caution when servicing or performing maintenance on any
parts containing hot water. To avoid severe burns, allow equipment to cool before
performing maintenance.

INTRODUCTION
The ecosmart Select hydronic furnace is designed to maximize performance and comfort in
residential or light commercial applications. The ecosmart can be used with a variety of heat
sources such as boilers and water heaters and can be implemented in combo systems that
provide domestic hot water as well as space heating. Smart control systems within the
ecosmart allow extraction of maximum heat by allowing condensing high efficiency heat
sources to work at their maximum efficiency while providing ultimate comfort with unmatched
performance.
Simple, independent heat/cool and system parameters can easily be set by the installer to
adjust for a wide variety of installations.
The ecosmart features a 5-speed high efficiency EC fan motor and a pump control which can
operate a standard 120VAC pump or a variable speed pump from the 0-10V interface that
provides LO/MED/HI functionality.
MODES OF OPERATION
MULTI STAGE – fan runs through 3 speed stages with 5 minute intervals until the
selected speed is reached, and the pump if a variable type is installed, runs through 3
speeds in unison with the fan stages. Note if a standard pump is used, the pump will run
at a single speed only.
SINGLE STAGE – fan runs at the selected speed and the pump runs at a single speed.
