LOCATION: (See Figure 2)

Locate the water heater as close as possible to an
exterior wall to minimize the length of flex duct required.
However, the minimum length available is 5 feet

and under no circumstances must any component be
altered. Consider the direction of predominant winds
and the possible snow accumulation against that side of
the building.
