water heaters have been supplied with
factory installed 3/4” NPT heat traps in
the hot outlet line and cold water inlet
line.
These heat traps may require a minimum
of one (1) 90° 3/4” NPT elbow and may
require an additional 90° 3/4” NPT elbow
or a 3/4” coupling depending on your
installation needs. See Illustration of
nipples and heat traps on page 33.
