Minimum and Maximum Vent Length
CAUTION: Before
proceeding, make sure you
understand the procedure
and cautions covered in the
sections “Joining Pipes
and Fittings” and
“Cementing Joints”.
Joining Pipes and Fittings
All pipe, fittings, solvent cement, primers and procedures must conform to American
National Standard Institute and American Society for Testing and Materials
(ANSI/ASTM) or CSA standards.
Cementing Joints
All joints in the vent piping must be
properly sealed and we recommend using
the following material:
PVC materials should use ASTM D-2564
grade cement.
CPVC materials should use ASTM F-493
grade cement.
ABS materials should use ASTM D-2235
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 bottoms 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. The proper brush size is one inch.
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 vent pipe used
(PVC, CPVC or ABS).

WARNING: DANGER
OF FIRE OR BODILY
INJURY - Solvent cement
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 warning on
material containers.

* For the 3” and 4” vent, one 90° elbow is
approximately equal to 5 feet (1,5m) of pipe.
One 45° elbow is approximately equal to 2.5
feet (76,2cm) of pipe.
