Protection Association" (NFPA) 70 and local/state codes. In Canada, electric grounding
conforms to the Canadian electric code CSA 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.
