CAUTION: Do not install furnace in a corrosive or
contaminated atmosphere. Make sure all combustion and
circulating air requirements are met, in addition to all
local codes and ordinances.
CAUTION: Do not operate the furnace during construc-
tion. If the furnace is required, use clean outside air free
of chlorine and fluorine compounds for combustion and
ventilation. These compounds form acids that corrode the
heat exchangers and vent system. These compounds are
found in paneling and dry wall adhesives, paints, thin-
ners, masonry cleaning materials, and other solvents.
WARNING: DO NOT install the furnace on its back.
Safety control operation will not perform properly. A
failure to follow this warning can cause a fire, personal
injury, or death.
