PROPRIETARY AND CONFIDENTIAL
Note:
Condensate piping shall be CPVC or PVC
material and shall not be smaller than the
drain connection on the appliance.
Components of the condensate drainage
shall be CPVC or PVC material. All
components shall be selected for the
pressure and temperature rating of the
installation.
Where the drain pipes from more than one
unit are manifolded together for
condensate drainage, the pipe or tubing
shall be sized in accordance with an
approved method as dictated
by local codes.
Condensate must be disposed of according
to local codes.
Pump should be controlled by an Aquastat,
Timer or Combination Aquastat and Timer.
Pump should be sized to maintain
circulation loop temperature.
Pump should be sized to overcome the
pressure loss through the tankless water
heater, supply, and return plumbing.
Reference the Rinnai Hot Water System
Design Manual for pump sizing guidelines.
Pump should be of bronze or stainless
construction.
Reference the Common Vent Installation
Manual for common vent options. Air intake
shown for direct vent installations only.
Reference Water Heater IO Manual for
cascading instructions.
Ensure tankless heaters are installed in
parallel to maximize system output.
Contact Application Engineering Center of
Excellence if alternate piping arrangements
will be considered.
Balancing of hot water risers may be
necessary after installation to ensure
