A CAUTION
Do not install furnace in a corrosive or contaminated
atmosphere. Make sure aU combustion and circulating
are requirements hsted in “Procedure for Induced-Com­
bustion Furnaces” are adhered to, in addition to all
local codes and ordinances.
Do not use this furnace during construction when adhe­
sives, sealers, and/or new carpets are being installed. If
the furnace is required during construction, use clean
outside air for combustion and ventilation. Compounds
of chlorine and flourine when burned with combustion
air form acids which will cause corrosion of the heat
exchangers and metal vent system. Some of these com­
pounds are: paneling and dry wall adhesives, paints,
thinners, masonry cleaning materials, and many other
solvents commonly used in the construction process.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
