Safety Considerations
Improper installation, adjustment, alteration, service maintenance, or use
can cause explosion, fire, electrical shock, or other conditions which
may cause death, personal injury, or property damage. Consult a
qualified installer, service agency, or your distributor or branch for
information or assistance. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this product.
Refer to the individual instructions packaged with the kits or accessories
when installing.
Follow all safety codes. Wear safety glasses, protective clothing, and
work gloves. Have a fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions included in literature and
Installation Instructions

attached to the unit. consult local building codes, the current editions of
the National Fuel Gas Code (NFGC) NFPA 54/ANSI Z223.1, and the
National Electrical Code (NEC) NFPA 70.
In Canada refer to the current editions of the National Standards of
Canada CAN/CSA-B149.1 and .2 Natural Gas and Propane Installation
codes, and Canadian Electrical Code CSA C22.1
Recognize safety information. This is the safety-alert symbol
you see this symbol on the unit and in instructions or manuals, be alert to
the potential for personal injury. Understand these signal words:
DANGER, WARNING, and CAUTION. These words are used with the
safety-alert symbol. DANGER identifies the most serious hazards which
will result in severe personal injury or death. WARNING signifies
hazards which could result in personal injury or death. CAUTION is
used to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
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 only, please visit the
