2.5 SUPPLY AND RETURN PIPING
The Benchmark Boiler utilizes 4” (10.16cm) 150# flanges for the water system supply and return
piping connections. The physical location of the supply and return piping connections are on the
rear of the unit as shown in Figure 2-3.

The optional dual inlet connections on the Benchmark 1500 and 2000 allow these units to be
configured with a separate cooler return temperature zone, rather than blending high and low
return temperature zones. Utilizing the dual return capability of these boilers can take further
advantage of the condensing capabilities of these models. When configured with a lower return
temperature zone or AERCO SmartPlates, thermal efficiency can improve by up to 10%.
If your unit includes the secondary inlet, pipe the warmer return water to the secondary (upper)
inlet and the cooler return water to the primary (lower) inlet. Contact your AERCO
representative for additional information.
