FIGURE 17.
Cementing PVC, ABS or CPVC Pipe and Fittings
Read and observe all safety information printed on printer, cleaner,
and cement container.
DANGER
Primer, cleaner, and cements are extremely flammable. They
are harmful or fatal if swallowed. The vapors are harmful. They
may irritate eyes and skin and can be absorbed through the skin.
PRECAUTIONS
Always store primers, cleaner, and cements in cool, dry, well
ventilated places. Do not store these near heat, sparks, or flames.
Keep container closed. Use them in well ventilated areas. Wear
impervious clothing while handling. Do not smoke, eat, or drink
while handling. Wash thoroughly after handling and before eating.
Wear eye protection when handling. If swallowed, drink water,
do not induce vomiting, and call a physician or poison control
center immediately. If inhaled, get fresh air and seek medical
attention if ill feelings persist. In case of eye and skin contact,
immediately flush with plenty of water for 15 minutes and seek
medical attention if irritation persists. KEEP OUT OF REACH OF
CHILDREN.
All primers, cleaners and cements must meet all local codes and
applicable standard of the American Society For Testing Materials
Standards.
Before using primers, cleaners, and cements, stir or shake,
making sure contents are liquid. Do not use if found to be lumpy
or jelly-like.
1. Cut pipe ends squarely, removing all burrs and dirt.
2. Dry fit pipe and fittings to be connected for proper fit.
3. Clean pipe and fitting with a primer/cleaner.
4. Apply a thin coat of cement to fitting, avoiding puddling inside.
5. Apply a liberal coat of cement to pipe, leaving no voids.
6. QUICKLY assemble parts while cement is fluid! If you wait
too long, re-coat pipes.
7. Push pipe completely into socket of fitting, turning as it goes
until it bottoms.
8. Hold pipe and fitting together for 30 seconds. Then carefully
clean off excess with a cloth. Allow connections a sufficient
time to cure before disturbing.
9. Remember that vent pipes must be adequately and securely
supported.
APPROXIMATE SETTING TIME FOR 2-1/2" to 4" PIPE JOINTS.

CUTTING OPENINGS THROUGH AN OUTSIDE WALL AND
COLLAR INSTALLATION
After reading the manual and you have determined the location
of the opening in the wall, (using the drawing below), cut one
3-1/2" (89 cm) diameter hole for the inlet vent piping and one
3-1/2" (89 cm) diameter hole for the outlet vent piping through an
exterior wall.
NOTE: When determining locations of the openings in the
outside wall allow for the 1/8" (3.2 mm) rise per 5' (1.52 m) that
has taken place in the horizontal run.
FIGURE 19.
The 3" PVC, ABS or CPVC Schedule 40 vent pipe can be run from
the water heater through the wall or from the wall to the water
heater, whichever is most convenient. The vent pipe must extend
a minimum of 1-1/2" (38 mm) through the exterior wall. Extending
the vent cap as far as possible from the surface of the exterior
