DANGER
CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace 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
Goodman 38
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, direct outside
ventilation.
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 emissions can be (re)circulated throughout the
structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain
damage or death.
