WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury and/or
death.
Carbon Monoxide (CO) is a colorless, odorless, and tasteless poisonous
gas that can be fatal when inhaled. Follow all installation, maintenance,
and service instructions. See additional information below regarding
the installation of a CO Alarm.
Most states in the USA and jurisdictions in Canada have laws that
require the use of Carbon Monoxide (CO) alarms with fuel burning
products. Examples of fuel burning products are furnaces, boilers, space
heaters, generators, water heaters, stoves/ranges, clothes dryers,
fireplaces, incinerators, automobiles, and other internal combustion
engines. Even if there are no laws in your jurisdiction requiring a CO
Alarm, it's highly recommended that whenever any fuel burning product
is used in or around the home or business that the dwelling be equipped
with a CO Alarm(s). The Consumer Product Safety Commission
recommends the use of CO Alarm(s). The CO Alarm(s) must be
installed, operated, and maintained according to the CO Alarm
manufacturer's instructions. For more information about Carbon
Monoxide, local laws, or to purchase a CO Alarm online, please visit the
following website. https://www.kidde.com.
SAFETY CONSIDERATIONS
!
FIRE, EXPLOSION, ELECTRICAL SHOCK, AND
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in dangerous operation,
serious injury, death, or property damage.
Improper installation, adjustment, alteration, service, maintenance, or
use could cause carbon monoxide poisoning, explosion, fire, electrical
shock, or other conditions which may cause personal injury or property
damage. Consult a qualified service agency, local gas supplier, or your
distributor or branch for information or assistance. The qualified
service agency must use only factory-authorized and listed kits or
accessories when modifying this product.
