In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient
space for piping connections and future service/maintenance requirements must also be taken
into consideration. All piping must include ample provisions for expansion.

If installing a Combination Control Panel (CCP) system, it is important to identify the
Combination Mode Boilers in advance and place them in the proper physical location. Refer to
Chapter 5 for information on Combination Mode Boilers.

2.5 SUPPLY AND RETURN PIPING

The Benchmark 2.0LN Boiler utilizes 4” 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. Refer to Appendix F, Drawing AP-A-798 for additional dimensional data.
