Page 4: Safety Information
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. -
Page 5: Introduction
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. -
Page 6: Step Modulating Mode
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. - Page 7 PERFORMANCE RATINGS ES50LVP Performance Data - Hot Water Capacities (BTUH) @ 70°F Entering Air Temperature WATER PD ecosmart Air Pressure Drop: 0.04 IWC (FT-WG) ES50LVP Entering Water Temperature @140°F 110°F 120°F 130°F 140°F 150°F 160°F 170°F 180°F 10,640 13,320 16,010 18,700 21,400 24,100...

Page 11: Quick Start-Up Procedures
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. -
Page 12: Installation
INSTALLATION The installer must comply with all local and national code requirements pertaining to the installation of this equipment. Clearances The ecosmart is approved for up-flow, down-flow, and horizontal configurations. Clearances do not change with orientation. This hydronic furnace is for indoor installation only. Clearance from Recommended Service Combustibles (in) -
Page 13: Ecosmart Mounting
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. -
Page 14: Pump
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. - Page 15 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.

Page 27: Service And Maintenance
SERVICE AND MAINTENANCE NOTE: The ecosmart is not to be used for temporary heat during construction. Use for this purpose will void equipment warranty. Filter Inspect the filter monthly and replace, remove and vacuum or rinse as required. A clogged or inadequate filter may void product warranty. -
Page 28: Troubleshooting
TROUBLESHOOTING Thermostat call error If the ecosmart does not run when the thermostat is calling, jumper R to W for heating, or R to Y (Y2) to verify if the problem is with the thermostat or ecosmart control. Note that some thermostats have a delay (typically five minutes) before they will re-start cooling. -
Page 29: Cold Water At Hot Faucet
Cold water at hot faucet When the heat source is a water heater, the most probable cause is reverse flow through the heating loop from a stuck check valve - repair or replace valve. Fan runs for cooling but not for heating The room thermostat may be connected improperly.
