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 thatrequire
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
