SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, main-
tenance, or use can cause explosion, fire, electrical shock or
other conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The
Installation Instructions
Page
qualified installer or agency must use factory-authorized kits
or accessories when modifying this product. Refer to the indi-
vidual instructions packaged with the kits or accessories when
installing.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloths for brazing operations and have
a fire extinguisher available. Read these instructions thor-
oughly and follow all warnings or cautions attached to the
unit. Consult local building codes and appropriate national
electrical codes (in USA, ANSI/NFPA70, National Electrical
Code (NEC); in Canada, CSA C22.1) for special require-
ments.
It is important to recognize safety information. This is the
safety-alert symbol
. When you see this symbol on the unit
and in instructions or manuals, be alert to the potential for per-
sonal injury.
Understand the signal words DANGER, WARNING, CAU-
TION, and NOTE. 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. CAU-
TION 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 instal-
lation, reliability, or operation.
WARNING
CARBON-MONOXIDE POISONING HAZARD
Failure to follow instructions could result in severe person-
al injury or death due to carbon-monoxide poisoning, if
combustion products infiltrate into the building.
Check that all openings in the outside wall around the vent
(and air intake) pipe(s) are sealed to prevent infiltration of
combustion products into the building.
Check that furnace vent (and air intake) terminal(s) are not
obstructed in any way during all seasons.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation and ser-
vice. There may be more than one disconnect switch. Tag
all disconnect locations to alert others not to restore power
until work is completed.
