Installing the New Water Heater (cont'd)

Cementing PVC, ABS OR CPVC Pipe and Fittings

Read and observe all safety information printed on primer, cleaner, and cement containers.

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 them near heat, sparks, or flames. Keep containers 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 standards 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 care- fully 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.

VENT PIPE SEPARATION

The inlet and outlet vent pipes must be separated by a min- imum distance of 61/2″ inches up to 24 inches maximum.

61/2″ MIN.

24″ MAX.

NOTE: Inlet and outlet vent pipes from multiple power direct vent water heaters must be separated from adjacent heater vent pipes by a minimum of 61/2″.

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 31⁄2″ diameter hole for the inlet vent pip- ing and one 31⁄2″ diameter hole for the outlet vent piping through an exterior wall.

NOTE: When determining location of the openings in the outside wall allow for the 1⁄8″ rise per five feet that has taken place in the horizontal run.

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 11⁄2″ through the exterior wall. Extending the vent cap as far as possible from the sur- face of the exterior wall will help minimize discoloration of the wall. Note that the inside flue mounting adaptors must be slipped over the vent piping before locating the pipe through the wall. Before securing the inside and outside collars to the wall, use a silicone sealer between pipe and opening to insure a water and air tight seal.
