Optional Vertical Vent Kit with Standard Horizontal Vent Kit - Installation #2
Any Optional Vent Kit
*Each part is stamped with a part number.
The opening through the wall should be cut at this time. If this has not been done, refer to “Cutting The Opening Through The Outside Wall,” onpage11.
1.First it must be determined how far the vertical 3” (76 mm) diameter telescoping flue sections are set and locked together using the two screws supplied.
FIGURE 31 .
Use chart #3, drawing and simple equation below, to find the length of expansion of the telescoping flue sections. Because of manufacturing tolerances, place the telescoping extension on the water heater and adjust the height (“X” Dimension) and mark the point. Once the length has been determined, lock the two sections together by drilling two holes (180° apart) in the pipe and securing with the screws supplied.

2.Set the vertical 3” (76 mm) diameter telescoping flue section in place on the flue collar. Using a # 22 drill bit, drill two holes (180° apart) and secure the vertical assembly to the flue collar.

3.Slide the 6” (152 mm) vent telescoping section apart to reveal the beads. Using the caulking supplied, fill the beads.

4. Apply an ample amount of sealant around the oval flare of the jacket.

5.Place the 6” (152 mm) vent section over the 3” (76 mm) flue section. Subtract 3/4” (19 mm) from the predetermined “X” dimension. This determines the length of the 6” (152 mm) vent extension. Slide the 6” (152 mm) vent extension apart to this dimension and secure with the two screws supplied.

6.Form the round end of the 6” (152 mm) vent extension to the top of the jacket and secure with four sheet metal screws.
