1.
Installation diagram shown above is n example of a typical (recommended) install. Additional zones are allowed, as well as
alternative piping layouts.
2.
Unit configurations/model includes indirect DHW tank.
3.
A flex tubing kit has been provided with the unit and should be installed at the outdoor unit. An automatic air vent and air
separator are supplied as field 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 flushing/purging of air from system.
5.
Bypass valve (required) is used to avoid dead-heading pump if all zone valves are closed. See
Figure 11
for details.
6.
Field Provided
7.
At highest point in the system.
8.
Closely spaced tees for connection to backup boiler. See
Figure 12d
for details
9.
Always check local code requirements to ensure that the installation meets current regulatory standards.
