WALL AND COLLAR INSTALLATION
After reading the manual and you have determined the location
of the op,eningin the wall, (using the draw!ng below), cut a 2_" hole for 2 vent piping or a 3_' hole for 3 vent piping through an exterior wall.
NOTE: When determining location of the opening in the outside wall allow for the ¼° rise per five feet that has taken

The 3" (or optional 2") 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_" 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 locat- ing 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.
