INTRODUCTION
The ecosmart 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. Various parameters are automatically monitored and
fan and pump speeds vary simultaneously. The ecosmart has a built-in variable speed pump
controller that can vary the speed of a standard single speed AC pump.
MODES OF OPERATION
Three modes of operation are available:
1. Full modulation – full control of fan and pump (requires outdoor temperature sensor).
2. Step modulation – timed fan and pump sequencing.
3. Single stage – standard furnace emulation.
Modulating Mode
(ecosmart outdoor sensor installed)
Water temperature is set at the heat generator by referring to the heat generator performance
data. It is best to maintain constant water temperature at the heat generator.
If the heat generator comes with an optional outdoor temperature sensor do not
install it as it will conflict with the ecosmart control.
5 | P a g e
The fan operates at the speed selected on the HEAT CFM switch during the setup. Fan and
pump speed automatically reduce as outdoor temperature rises. Fan CFM may reduce by up to
30% from the HEAT CFM switch setting depending on outdoor temperature.
If the heat generator includes a built-in pump, and it is directly connected to the ecosmart, the
ecosmart will vary the pump automatically. If the system is configured for primary/secondary
pumping and the heat generator includes a pump, the secondary pump can be controlled by
the ecosmart.
Step Modulating Mode
(ecosmart outdoor sensor not installed)
Water temperature is set at the heat generator by referring to the heat generator performance data.
Fan operates at 50% of the HEAT CFM setting for 5 minutes then increases to 75% for a further 5
minutes, then increases to 100% until the thermostat is satisfied. If the pump is controlled by the
ecosmart, its speed will be adjusted accordingly as the ecosmart goes through its stages. If the pump is
controlled by the heat source, it will function according to the heat source control strategy.
Basic Mode
(ecosmart outdoor sensor not installed)
Water temperature is set at the heat generator by referring to the heat generator performance
data. Fan operates at 100% of selected HEAT CFM and pump operates at maximum speed until
the thermostat is satisfied.

QUICK START-UP PROCEDURES
Refer to the superseding installation instructions before following the start-up procedures.
1. Fill the system with water. Do not start the system.
2. Purge all air from the system. Isolation and purge valves are strongly recommended.
3. Purge all air from the space heating loop by closing the isolation valve on the return leg
of the loop and open the drain to purge air. Open the return leg isolation valve and
then close the drain valve.
4. Start the hot water generating equipment per the manufacturer’s recommendations.
Set the design water temperature to deliver the necessary amount of BTUs to the air
handler.
5. Once all air has been purged, turn on the power to the ecosmart and set the room
thermostat to heat and set the temperature high enough to initiate a call for heat. This
will energize the air handler an in turn the fan and pump.
6. Once the heat source is supplying hot water, check supply and return pipes for a
temperature difference to make sure there is flow. There should be a noticeable
difference in temperature between supply and return lines. Use caution when supply
water temperature is above 120 F / 49 C.

Freeze Protection
It is not recommended to install the ecosmart in an unheated space.
Should the ecosmart be installed in an area where the ambient temperature may fall below
freezing, ethylene or propylene glycol should be added into the hydronic heating system to
protect against damage, which would not be covered under warranty. Make sure the glycol is
compatible with all system components and is permitted by local and national codes.
Rear Piping Connections
The heating coil may be reversed to allow rear piping:
Remove upper door
Disconnect supply air sensor from extension cable
Slide out heating coil
Re-mount supply air sensor and grommet to opposite end of heating coil
Remove rear knock-outs
Slide in heating coil
Use plastic plugs (provided) to close up holes on upper door
12 | P a g e
Ecosmart Mounting
The ecosmart can be installed in upflow, downflow and left or right horizontal applications.
Install the ecosmart with the door in place to make sure the cabinet remains square. Flip the
unit for downflow applications so that the top of the unit is now the bottom. No modification is
required for any configuration.
The ecosmart can be suspended from floor joists, rafters or concrete using rods, pipe, angle
supports or straps. Units must be hung level to ensure quiet operation.
CAUTION - Use any of the existing screw holes in the cabinet when using straps. If
the existing screw is too short for securing a mounting strap, a longer screw should
be used provided care is taken not to damage any internal components. Product
warranty does not cover any damage or claims resulting from damage from longer
screws or from the unit being improperly suspended.
The cabinet is designed so that the return air can be located on either side of the cabinet, or
from the bottom of the cabinet. Position a filter rack so that the filter is readily accessible. A
filter and filter rack are not included. Sides are marked for a standard 16 x 20 in filter rack.
WARNING - Special care should be taken in the vicinity of the coil to avoid
puncture. Screw into opening flange instead of top of cabinet when fastening the
supply air duct.
Plumbing
Install a sediment faucet or ball valve for use as a drain/purge valve. The drain valve must be
located downstream of the pump and check valve, and upstream of the isolation valve (if
isolation valve is present). With this arrangement, any air trapped in the system can easily be
flushed out following the instructions in the Start-up & Troubleshooting sections.
Isolation valves are recommended ease of servicing.
When the space heating loop connections are made to the domestic water connections:
The heating loop connections should be positioned horizontally in a vertical section of
the domestic water line for both inlet and outlet. Refer to the piping schematic for
details.
Connect the heating loop to the domestic water connections as close to the water
heater as possible
13 | P a g e
Avoid sections of pipe in the heating loop that can trap air where possible. It is usually
impossible to install a system without having at least one part of the system or heating coil able
to trap air. This will not be a problem if the connection to the domestic water lines is made
properly, and purge valves and air eliminator devices are installed.
Following the flushing procedures in the Start-up section will ensure that there is no air
in the system after initial set-up.
Follow recommendations supplied by the manufacturer of the heating source being used.
ecosmart includes a flow switch connection where a flow switch can be connected to allow for
domestic water priority. Note: the correct type of flow switch is a normally open (NO) device.
The flow switch closes when domestic water is flowing.
Check Valve
A check valve may be required for your system to meet local codes and to work effectively. A
check valve:
Protects against back-flow of water to avoid short circuiting around the water heater
during domestic use
Protects against thermal siphoning
Is required in all potable water systems
Pump
A pump is not included inside the ecosmart. Whether you are using an external pump or an
internal built-in pump, it should be sized for the system. Pumps supplied with the heat
generating units can be used as the sole pump provided it meets the needs of the system. This
is especially the case in retrofit applications where a much larger pump may have previously
been used in the system.
The ecosmart includes a built-in variable speed pump controller that can control a standard
single speed pump up to 250 watts. Operational modes are as follows:
When set up in modulating mode, the pump will operate as a continuously variable
speed pump
When set up in step-modulating mode, the pump will operate as a multi-speed pump.
When set up in basic mode, the pump will operate as a single-speed pump
14 | P a g e
The ecosmart controller has a built-in pump timer that exercises the pump for 1 minute
every 24 hours to prevent the possibility of ‘sticking’ due to sediment etc
Water Heater or Boiler Setup
Follow the manufacturer’s installation and start-up instructions of the water heater or boiler.
Make sure the equipment is turned off during installation and service. Make certain the
equipment has been refilled and all air is purged from the system before turning on the heater.
WARNING - When the system requires water temperatures higher than 120F,
a mixing valve shall be installed to reduce domestic hot water temperature to
safeguard against scalding.
Combo Systems
The ecosmart is ideal for use in combo systems which provide space heating and domestic hot
water from a single heat source. Any properly sized gas, propane or oil fired water heater or
boiler will work in a combo system. Make sure any water heater being used is approved for
combo applications.
