NeoTherm units can be installed in many different
arrangements. The steps in the installation will be
different, depending on the number of boilers in the
system, the venting arrangements, the control signals
used, and so on. In this section, we will list the steps
necessary to do the most common installations.
1. Table 12 lists most of the common
configurations for NeoTherm systems. Look
through the table until you find a line that
