2.5 WATER INLET AND OUTLET PIPING

The locations of the 2" (5.08 cm) NPT cold water inlet and hot water outlet piping connections
are shown in Figure 2-3a. Flow rates through the unit are limited to 50 gallons (189 Liters) per
minute continuous.
Shut-off valves and union connections must be installed in the inlet and outlet lines for
maintenance. The use of dielectric unions is recommended.
When connecting the hot water outlet and cold water inlet to building piping, first make sure the
threads are thoroughly clean. AERCO recommends using Loctite ® 7649 to prime the threads
and then Loctite 567 as pipe dope. Do NOT use Teflon tape.
If the Innovation Hot Water Boiler is equipped for use with the C-More
Water Heater Management (WHM) system, then an actuator-controlled ball
valve will be included with the shipment. Refer to section 2.5.1 for
installation instructions prior to connecting inlet piping.
All piping must be arranged so that it does not interfere with the
removal of any covers, inhibit service or maintenance, or prevent
access between the unit and walls, or another unit.
