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.

	MOVEMENT	COMPLETE

90°F (32°C) TO 150°F (66°C)	3/4 hr.	8 hrs.
50°F (10°C) TO 90°F (32°C)	1 hr.	15	hrs.
9°F (-12°C) TO 50°F (10°C)	1-1/3 hr.	18	hrs.

VENT PIPE SEPARATION

The inlet and outlet vent pipes must be separated by a minimum distance of 6-1/2" (16.5 cm) up to 24" (61cm) maximum.

FIGURE 18.

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
