Use the simple equation below, chart and drawing 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.
EQUATION: C - A - 10” = X

5.Place the 6” vent section over the 3” flue section. Subtract 3/4” from the X dimension used earlier and this gives the length of the 3” vent extension. Slide the 6” vent extension apart to this dimension and lock it together using the two screws supplied.

6.Bend the round end of the 6” vent extension oval at the jacket tip and secure it using four sheet metal screws.
*See models and rating plate attached to the water heater for specific model number and other detailed information.

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

7. Place the 3” elbow on the flue extension.
NOTE: Make sure elbow is properly aligned to opening in the outside wall.
Mark the 3” dia. end of the flue extension at the slots in the elbow. Using a #22 drill bit, drill holes into the flue extension at the two slots and secure the elbow to the flue extension using the screws provided.
