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 is 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

discharge openings for both horizontal and downflow configurations,
and are factory shipped with all downflow duct openings covered. Units
may be installed either on a rooftop or on a cement slab. (See
roof curb dimensions).
In gas heating mode, this unit is designed for a minimum continuous
return-air temperature of 55°F (13°C) db and a maximum continuous
return-air temperature of 80°F (27°C) db. Failure to follow these
return-air temperature limits may affect reliability of heat exchangers,
motors, and other components.
Models with a N in the 13th position of the model number are dedicated
that are Low NOx units designed for California installations. These
models meet the California maximum oxides of nitrogen (NOx)
emissions requirements of 40 nanograms/joule or less as shipped from
the factory and must be installed in California Air Quality Management
Districts or any other regions in North America where a Low NOx rule
exists.
NOTE: Low NOx requirements apply only to natural gas installations.
