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
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
