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

6. After it has been determined that
each appliance that remains
connected to the common
venting system properly vents
(when tested as outlined above),
return doors, windows, exhaust
fans, fireplace dampers and any
other gas-burning appliance to
their previous conditions of use.
7. If improper venting is observed
during any of the above tests, the
common venting system must be
resized.
When the furnace is installed in the
same space with other gas
appliances such as a water heater, be
sure there is an adequate supply of
combustion and ventilation air for the
other appliances. Do not delete or
reduce the combustion air supply
required by the other gas appliances
in this space. See Z223.1, National
Fuel Gas Code (NFPA54) for
determining the combustion air
requirements for gas appliances. An
unconfined space must have at least
50 cubic feet (volume) for each
1,000 BTUH of the total input of all
appliances in the space. If the open
space containing the appliances is in
a building with tight construction
(contemporary construction), outside
air may still be required for the
appliances to burn and vent properly.
Outside air openings should be sized
the same as for a confined space.
IMPORTANT: Only the current vent
instructions apply. All 90 Plus Gas
Furnaces cannot be common vented.

WARNING
PVC SOLVENT CEMENTS AND
PRIMERS ARE HIGHLY
FLAMMABLE. PROVIDE
ADEQUATE VENTILATION AND DO
NOT ASSEMBLE NEAR HEAT
SOURCE OR AN OPEN FLAME. DO
NOT SMOKE. AVOID SKIN OR EYE
CONTACT. OBSERVE ALL
CAUTIONS AND WARNINGS
PRINTED ON MATERIAL
CONTAINERS. 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:

CEMENTING JOINTS

Properly seal all joints in the PVC
vent using the following materials and
procedures.
PVC CLEANER-PRIMER AND
PVC MEDIUM-BODY SOLVENT
CEMENT
IMPORTANT: After cutting pipe,
remove all ragged edges and burrs.
This is important to prevent reduction
in pressure 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
surface of socket and outside of
pipe. Read instructions included
with the primer for proper
application.
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
movement 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 brush or the dauber supplied
with the can. The proper brush size is
one inch.
IMPORTANT: For Proper Installation
DO NOT use solvent cement that
has become curdled, lumpy or
thickened.
DO NOT thin. Observe shelf
precautions printed on containers.
For application below 32°F, use only
low-temperature-type solvent
cement.
