CHAPTER 1:
INSTALLATION
1.1 Piping Installation
WARNING!
Prior to appliance installation and/or maintenance, disconnect the appliance’s electrical power
supply and shut off the inlet gas valve. Failure to follow these instructions could result in severe
personal injury or death!
In order for the AM Cascade Sequencer to operate correctly, the AM Series heaters must be
installed as shown in Figure 1-1.
Because the cascade general sensor is installed on the Master heater, the Master heater must
always be the closest to the low loss header in order to provide the most accurate temperature
measurement.
A maximum of eight (8) heaters may be connected into the cascade system.
NOTE:
Figure 1-1
shows only one piping configuration example. Other piping configurations are
possible. Contact AERCO technical support for information concerning alternative
configurations.
