1. Installaon diagram shown above is n example of a typical (recommended) install. Addional zones are allowed, as well as
alternave piping layouts.
2. Unit conguraons/model includes indirect DHW tank.
3. A ex tubing kit has been provided with the unit and should be installed at the outdoor unit. An automac air vent and air
separator are supplied as eld installed components.
4. All piping must be “Home Run” style. All radiant manifolds and air handler unit zones valves should be located in the mechanical
room to facilitate ushing/purging of air from system.
5. Bypass valve (required) is used to avoid dead-heading pump if all zone valves are closed. See  for details.
6. Field Provided
7. At highest point in the system.
8. Closely spaced tees for connecon to backup boiler. See  for details
9. Always check local code requirements to ensure that the installaon meets current regulatory standards.
