section of this manual and you have chosen a suitable water
heater installation site, use the chart below to determine
dimensions for the opening in the wall.
Cut a 6

WATER HEATER ATTITUDE
There is a certain amount of variance 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.

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