NOTES:
1. Minimum pipe size should match connection size. Upsize pipe accordingly if greater ow is required.
2. A thermal expansion tank suitable for potable water must be sized and installed within this piping system between the backow preventer
and the cold water inlet.
3. All circulators should have an integral ow check.
4. Drains and check valve between unit and storage tank will assist in purging air from system.
5. This drawing is meant to demonstrate system piping only. The installer is responsible for all equipment and detailing required by local codes.
In Massachusetts, you must install a vacuum relief valve per 248 CMR.
6. Always shut o power to the water heater or isolate the heater from the system if ANY plumbing work is to be done. Running the water
heater without water will result in dry-ring.
7. For further energy savings, install the SA Model on the same electrical circuit as the dishwasher.
The piping will not support the weight of the water heater circulator pump. Refer to the pump manufacturer’s installation
instructions to properly support the circulator pump. Failure to comply with these instructions could result in substantial property
damage, severe personal injury, or death.
