WATER HEATER ATTITUDE
There is a certain amount of variation permissible with regard
to the direction the water heater faces.
Standing in front of the water heater (gas control facing you), set
the 3” diameter elbow (slotted end) on the flue. This will give
you a better understanding of the relation of the vent assembly
to the opening in the wall and more importantly any possibly of
interference of venting and water piping.
The direction of the water heater can now be made. Also
consider the gas control valve to insure installation, lighting,
and maintenance accessibility are retained.

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 this assembly
in place on the end of the water heater’sflue collar.
FIGURE 15
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.

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

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.

5. Making sure the 6” diameter elbow is centered around the
3” diameter flue, secure the 6” diameter vent pipe using
four sheet metal screws at the connection of the jacket top.

6. The standard vent kit includes a 6” diameter extension pipe
which is used when “E” dimension is over 6 1/2”.
FIGURE 20
7. If “E” is less than 6 1/2” move to next step.
If “E” dimension is over 6 1/2”, assemble the 6” diameter
extension pipe (crimped end) to the 6” diameter vent elbow
and secure using two sheet metal screws.
