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
* See models and rating plate attached to the water heater for
specific model number and other detailed information.

Set the vertical (3” 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.

Slide the 6” vent telescoping section apart to reveal the
beads. Using the caulking supplied, fill the beads.

Using the tube of sealant supplied, run an ample amount
around the oval flare of the jacket.
FIGURE 37
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 6” vent extension. Slide the 6” vent extension
apart to this dimension and lock it together using the two
screws supplied.

Bend the round end of the 6” vent extension oval at the
jacket top and secure it using four sheet metal screws.

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 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.
