2.6 INSTALLING THE TEST HOSE BIB AND DRAIN VALVE
A Test Hose Bib must be installed upstream of the hot water outlet shut off valve, This is
required for startup and testing (see Figure 2-5 A). The pipe diameter should be a minimum of
3/4". The Test Hose Bib cannot be omitted.

The drain valve, which is shipped loose, must be installed on the cold water inlet. It is suggested
that it be installed on the right side of the unit, on a nipple attached to the building recirculation
inlet (see Figure 2-5 B), with a cap on the end. It could instead be installed on the cold water
inlet pipe, on the left side of the unit.
