Very Important Set-Up Instructions - Rheem AdvantagePlus HE55-100N Use & Care Manual

4. Horizontal lengths of exhaust vent must slope back
towards the water heater not less than ¼" per foot
to allow condensate to drain from the vent pipe. If
the exhaust pipe must be piped around an obstacle
that results in the creation of a low point, condensate
will collect in this low point and form a blockage. This
condensate must be drained away using a field-
installed condensate drain assembly as shown. (See
page 19)
5. All piping must be fully supported. Use pipe hangers
at a minimum of 4 foot (1.2 m) intervals to prevent
sagging of the pipe where condensate may form.
6. Do not use the water heater to support any piping.
7. A screened straight coupling is provided with the water
heater for use as an outside exhaust termination.
