lating air requirements listed in “Procedures for
Natured-Draft Gas-Fired 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 fluorine when burned with combustion

thinners, masonry cleaning materials, and many other
solvents commonly used in the construction process.
