piping or venting. All external piping and venting
must be supported independently of the appliance.

foundation, such as concrete, where the floor is not
level or where water may accumulate around the
appliance. The floor must be able to support the
weight of the appliance, water, and all additional
system components.

a condensate pump, if required.

flooring. Acceptable flooring includes a level metal
or wooden base capable of holding the weight of
the appliance. The base shall extend beyond the
edges of the appliance by at least 3 inches (76.2
mm) in any direction. This appliance shall never be
installed directly on carpeted flooring.
a. For closet or alcove installation, the base shall
cover the entire floor.
