CUTTING OPENING THROUGH AN OUTSIDE WALL AND COLLAR
INSTALLATION
Determine the location of the opening in the wall and cut a 3 3/4” hole
(30 & 40 Gallon) or 4 3/4” hole (50 Gallon) through an outside wall.
The 3” or 4” 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” through the exterior wall. Note that the inside collar 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,
see Figure 23.

the heater to operate.
CEMENTING PVC, ABS OR CPVC PIPE AND FITTINGS
Read and observe all safety information printed on primer, cleaner, and
cement containers.
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.
Always store primer, cleaner, and cements in cool, dry, well ventilated
places. 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 vomitting, 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 minuttes 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 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,
recoat 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 distrurbing.
9. Remember that vent pipes must be adequately and securely
supported.
