CUTTING OPENING THROUGH AN OUTSIDE WALL AND COLLAR INSTALLATION

Determine the location of the opening in the wall and cut a 3 3/4” (9.53 cm) hole (30 Gallon (113.56 Liter) & 40 Gallon (151.42 Liter)) or 4 3/4” (12.07 cm) hole (50 Gallon (189.27 Liter)) through an outside wall.

The 3” (7.62 cm) or 4” (10.16 cm) 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” (3.81 cm) 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.
