Use & Care Manual

There is no condensate collection and disposal required for
Rheem water heaters under most conditions. Installations
where the vent system length is short or where it runs
through conditioned space in the home, such as basements
or interior walls, do not typically cause condensation
and will not require any condensation disposal methods
regardless of vent pipe slope. The image on page 20
shows the recommended vent pipe slope of no less than
1/8 in. per foot (10 mm per m) away from the water heater.
Any condensation in the venting system will drain toward
the vent termination. The blower pipe coupling features a
capped drain port which is not needed in this case.
CAUTION: Make sure the drain port cap is
securely in place.
There are vent piping configurations, when combined with
certain environmental conditions that can produce enough
condensate to require collection and disposal. When a
slope away from the water heater cannot be achieved
and condensate handling is required in a horizontal vent
system, slope the vent pipe toward the water heater
1/8 in. per foot (10 mm per m) minimum and condensate
management means as follows:
• Remove the cap from vent pipe coupling, drain port
on the blower assembly.
• Connect 1/2 in. I.D, flexible, PVC (or equivalent
material), clear tubing to the drain port.
Notice: The tubing must be of sufficient length to
reach a floor drain, outside the building or other
required condensate disposal termination requirements
(Refer to local codes).
• Loop the drain tube so that it has a circular trap and
secure the top and
bottom of the loop with
wire ties or plastic zip
ties as shown. DO NOT
restrict any portion of
the drain tube. The
loop and all sections
of the tube must not be
restricted or collasped.
• Fill the drain tube
with water so that no
combustion gases might
vent into the room.
• Route the drain tube to a floor drain or outside the
building or refer to local codes for any condensation
requirements..
Installing the Water Heater
All joints in the vent piping must be properly
sealed and the following materials are recom-
mended:
PVC materials should use ASTM D2564 grade
cement.
CPVC materials should use ASTM F493 grade
cement.
ABS materials should use ASTM D2235 grade
cement.
Cleaner-Primer and Medium Body Solvent
Cement:
Cut pipe end square, remove jagged edges
and burrs. Chamfer end of pipe, then clean
fitting socket and pipe joint area of all dirt,
grease or moisture.
After checking pipe and socket for proper
fit, wipe socket and pipe with cleaner-prim-
er. Apply a liberal coat of primer to inside
surface of socket and outside of pipe. Do not
allow primer to dry before applying cement.
Apply a thin coat of cement evenly in the
socket. Quickly apply a heavy coat of
cement to the pipe end and insert pipe into
fitting with a slight twisting motion until it
bottoms out.
NOTICE: Cement must be fluid; if not,
recoat.
Hold the pipe fitting for 30 seconds to pre-
vent the tapered socket from pushing the
pipe out of the fitting.
Wipe all excess cement from the joint with a
rag. Allow 15 minutes before handling. Cure
time will vary according to fit, temperature
and humidity.
NOTICE: Stir the solvent cement frequently
while using. Use a natural bristle brush or
the dauber supplied with the can.
NOTICE: This unit is equipped with a
Flammable Vapor Sensor. Do not apply
power until enough time has passed to allow
the vapors from the primer and cement to
dissipate.
Cementing Joints
WARNING: DANGER OF
FIRE OR BODILY INJURY -
Solvent cements and primers
are highly flammable. Provide
adequate ventilation and do
not assemble near heat source
or open flame. Do not smoke.
Avoid skin or eye contact.
Observe all cautions and
warnings on material
containers.

Condensate Management - Optional Piping
CAUTION:
For proper installation:
DO NOT use solvent cement
that has become curdled,
lumpy or thickened.
DO NOT thin solvent cement.
Observe shelf precautions
printed on the containers.
For applications below 32°F
(0°C) use only low temperature
type solvent cement.
Appropriate solvent and
cleaner must be used for the
type of pipe used (PVC, CPVC
or ABS).
