17.Connect the vent cap by sliding its end over the 3” diameter extension pipe and O-ring.

NOTE: To facilitate ease of assembly of the vent cap to the 3” pipe, a soap solution can be applied to the O-ring gasket.

FIGURE 50

18.The vent cap has 4 holes around the outer edge. Remove the 4 screws used to temporarily attach the collar to the exterior wall. Then secure the vent cap assembly with the vent collar assembly to the exterior wall using the same 4 screws.

NOTE: Screws are supplied; however, substitution may be necessary depending on the exterior wall material.

CAUTION

To prevent unlocking the previously installed 3” diameter extension, the vent cap assembly must be rotated in a clockwise motion when the vent cap is installed.

19.Go back indoors to attach inside collar to the inside wall. Place the collar against the wall. Secure to wall by using 4 long sheet metal screws.

NOTE: Screws are supplied; however, substitution may be necessary depending on the interior wall material.

The opening through the wall should be cut at this time. If it hasn’t been, refer back to that section.

1.Lock the elbow to the straight 3” flue pipe. Set the assembly in place on the end of the water heater’s flue collar.

FIGURE 54

2.Mark the flue collar at the slots in the elbow. Using a #22 drill bit, drill holes into the flue collar at the two slots and secure the elbow to the flue collar using the screws provided.

NOTE: Make sure elbow is properly aligned to opening in the outside wall.

FIGURE 51

20.Using the tube of sealant supplied, run an ample amount of sealant around the edge of the vent pipe where it is inserted through the inside collar to seal air drafts from wall.

FIGURE 52

FIGURE 55

3.Using the tube of sealant supplied, run an ample amount around the oval flare of the jacket.

FIGURE 56

4.First remove the 3” horizontal extension from the elbow. Starting with the long end (with four securing holes), place the 6” diameter vent elbow over the 3” diameter elbow.

Bend the round end “oval” to fit the flared oval end of the jacket top.
