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
