Domestic Piping

TR/SMART Series Application

For applications requiring large volumes of domestic hot water over an extended period, the installer may include a Triangle Tube TR/SMART Indirect Water Heater in conjunc- tion with the PERFORMANCE PLUS. (See Fig. 10 page 19)

The domestic system recirculation, if used, is directed to the TR/SMART Series Tank. The circulator should be controlled by an aquastat.

The primary piping to the TR/SMART Series tank must comply with the piping methods details in SECTION V - Primary Piping or with other recognized piping methods.

Additional information regarding domestic and primary piping can be found in the TR/SMART Installation Manual.
