4.First remove the 3” (76 mm) horizontal extension from the elbow. Start- ing with the long end (with four securing holes), place the 6” (152 mm) diameter vent elbow over the 3” (76 mm) diameter elbow. Bend the round end “oval” to fit the flared oval end of the jacket top.
FIGURE18.
5.Making sure the 6” (152 mm) diameter elbow is centered around the 3” (76 mm) diameter flue, secure the 6” (152 mm) diameter vent pipe using four sheet metal screws at the connection of the jacket top.

6.The standard vent kit includes a 6” (152 mm) diameter extension pipe which is used when “E” dimension is over 6 1/2” (165 mm).
FIGURE 20.
7. If “E” dimension is less than 6 1/2” (165 mm) move to next step.
If “E” dimension is over 6 1/2” (165 mm), assemble the 6” (152 mm) diameter extension pipe (crimped end) to the 6” (152 mm) diameter vent elbow and secure using two sheet metal screws.Apply an ample amount of sealant around the joint to ensure a good seal.
