for water damage in connection with this appliance, or any
of its components.

rain, etc.,) during appliance operation and service
(circulator replacement, control replacement, etc.,).
4. Appliances located in a residential garage and in adjacent
spaces that open to the garage and are not part of the
living space of a dwelling unit must be installed so that all

clearance of not less than 18" (46cm) above the floor. The
appliance must be located or protected so that it is not
subject to physical damage by a moving vehicle.
