SAFETY CONSIDERATIONS

!
UNIT RELIABILITY HAZARD
Failure to follow this caution may result in unit component
damage.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, unit leveling, and unit sizing.
!
FIRE, EXPLOSION, ELECTRICAL SHOCK AND
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in electrical shock,
fire, personal injury, or death.
Improper installation,
maintenance, or use can cause carbon monoxide poisoning,
3
explosion, fire, electrical shock, or other conditions which
5
may cause personal injury or property damage. Consult a
7
qualified installer, service agency, local gas supplier, or your
