circuit may consist of an appropriate sized power cord which connected with the
grounding piece located in the unit control box and also connecting to the building
electric service panel. Other methods of grounding are permitted if performed in

c22.1. failure to observe this warning can result in electrical shock that can cause
personal injury.
Special warning for installation of furnaces or air handling units in
enclosed areas, such as garages, utility rooms or parking areas.
Carbon monoxide producing devices (such as an automobile, space heater,
gas water heater, etc.) should not be operated in enclosed areas such as
unventilated garages, utility rooms or parking areas because of the danger of
carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace
or air handler is installed in an enclosed area such as a garage, utility room or
parking area and a carbon monoxide producing device is operated therein, there
must be adequate ventilation directly to outside.
This ventilation is necessary to avoid the danger of CO poisoning which can
occur if a carbon monoxide producing device continues to operate in the enclosed
area. Carbon monoxide emission can be (re)circulated throughout the building if the
furnace or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.
