Cementing Joints; Joining Pipe And Fittings - Rheem RGFE Installation Instructions Manual

JOINING PIPE AND
FITTINGS
WARNING
PVC SOLVENT CEMENTS AND
PRIMERS ARE HIGHLY FLAM-
MABLE. PROVIDE ADEQUATE
VENTILATION AND DO NOT
ASSEMBLE COMPONENTS
NEAR HEAT SOURCE OR AN
OPEN FLAME. DO NOT
SMOKE. AVOID SKIN OR EYE
CONTACT. OBSERVE ALL CAU-
TIONS AND WARNINGS PRINT-
ED ON MATERIAL CONTAIN-
ERS. FAILURE TO FOLLOW
THESE GUIDELINES MAY
RESULT IN FIRE, EXPLOSION
OR ASPHYXIATION CAUSING
PERSONAL INJURY OR DEATH.
All pipe, fittings, solvent cement,
primers and procedures must conform
to American National Standard
Institute and American Society for
Testing and Materials (ANSI/ASTM)
standards as shown below:
PIPE & FITTING MATERIAL
Schedule 40 PVC (Pipe)
Schedule 40 PVC (Cellular Core Pipe)
Schedule 40 PVC (Fittings)
SDR-21PVC (Pipe)
SDR-26 PVC (Pipe)
Schedule 40 ABS Cellular Core DWV (Pipe)
Schedule 40 ABS (Pipe)
Schedule 40 ABS (Fittings)
ABS-DWV (Drain Waste & Vent)
(Pipe & Fittings)
PVC-DWV (Drain Waste & Vent)
(Pipe & Fittings)
IMPORTANT: The plastic combustion
air and venting components are MADE
of PVC. If using ABS piping, ensure that
the solvent cement is compatible for
joining PVC to ABS components or use
a mechanical connection that can with-
stand the vent temperatures and is cor-
rosion resistant.

CEMENTING JOINTS

Properly seal all joints in the PVC vent
using the following materials and proce-
dures:
PVC CLEANER-PRIMER AND
PVC MEDIUM-BODY SOLVENT
CEMENT
IMPORTANT: After cutting pipe, remove
all ragged edges and burrs. This is
important to prevent increase in pres-
sure drop throughout the system.
1. Cut pipe end square. Chamfer edge
of pipe. Clean fitting socket and
pipe joint area of all dirt, grease and
moisture.
2. After checking pipe and socket for
proper fit, wipe socket and pipe with
cleaner-primer. Apply
a liberal coat of primer to inside sur-
face of socket and outside of pipe.

3. 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 move-
ment until it bottoms out.
NOTE: Cement must be fluid; if
not, recoat.
4. Hold the pipe in the fitting for 30
seconds to prevent the tapered
socket from pushing the pipe out
of the fitting.
5. Wipe all excess cement from the
joint with a rag. Allow 15 minutes
before handling. Cure time varies
according to fit, temperature and
humidity.
NOTE: Stir the solvent cement
frequently while using. Use a
natural bristle, one inch wide
brush or the applicator supplied
with the can.
IMPORTANT: For Proper Installation
DO NOT use solvent cement that has
become curdled, lumpy or thickened.
DO NOT thin. Observe shelf precau-
tions printed on containers. For appli-
cation below 32°F, use only low-tem-
perature-type solvent cement.
For correct installation of the vent
pipe, follow the instructions provided
by the manufacturers of the pipe,
primer and solvent.
