All joints in the vent piping must be
properly sealed and the following
materials are recommended:
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-primer. 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 bot-
toms out.
NOTICE: Cement must be fluid; if not,
recoat.
Hold the pipe fitting for 30 seconds
to prevent 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.
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).
Determine the location for the concentric
vent and combustion air-inlet terminal
then make a hole through the roof and
interior ceiling(s) to accommodate the
terminal, vent and combustion air-inlet
system pipes. Insert the concentric vent
and combustion air-inlet terminal assem-
bly through the roof and interior ceiling(s)
as shown. Install the vent system and at-
tach it to the vent connector tting on the
water heaters blower assembly. Horizon-
tal lengths of the vent system must slope
downward away from the water heater a
minimum of 1/8 in. per foot (10 mm per
meter). Install the combustion air-inlet
system and attach it to the combustion
air-inlet connector tting on the water
heaters combustion air-inlet tube assem-
bly. Horizontal lengths of the combustion
air-inlet system must slope downward
from the water heater a minimum of 1/8
in. per foot (10 mm per meter). Support
vertical and horizontal lengths of the vent
and combustion air-inlet systems as previ-
ously mentioned. Determine the vent and
combustion air-inlet terminal heights and
cut the pipe accordingly. Refer to Figure
9 for the proper terminal heights. Insert
lengths of vent and combustion air-inlet
pipes through the ceiling wall as shown.
Install adequate ashing where the vent
and combustion air-inlet pipe passes
through the roof. Place the supplied ½
in. (1.3 cm) mesh metal screens inside the
terminal tting then connect a short piece
of pipe approximately 3 in. (7.6 cm) to the
terminal and elbows.
