CUTTING OPENING 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 a 2 1/2" hole for 2" vent piping, 3 1/2" hole for 3" vent piping or a 4 1/2" hole for 4" vent piping through an exterior wall. NOTE: When determining location of the opening in the outside wall allow for the 1/8" rise per five feet that has taken place in the horizontal run.

· If there is to be a vertical run of vent from blower, the 3" PVC, ABS or CPVC pipe must be attached to the blower using 3 sheet metal screws.
FIGURE 42.
The 3" )or optional 2" 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. Extending the vent cap as far as possible from the surface of the exterior wall will help minimize discoloration of the wall in this area which may be caused by the flue gases. 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.
