Downflow Gas-Fired Natural-Draft Furnaces
Installation, Start-Up and Service
Instructions
NOTE:
Read the entire instructions before starting the
installation.
NOTE:
The Energy Guide tag can be removed from the fur­
nace when the installation is complete.
INTRODUCTION
Before installing the furnace, refer to “Procedures for
Natural-Draft Gas-Fired Furnaces” (packaged with the
equipment) for information concerning combustion, venting,
piping, and other standard installation practices. Further
reference is made to the current edition of the National Fuel
Gas Code NFPA No. 54, T1A-54-1984-1/ANSI Z223.1-1984,
Z223.1a-1987.
Each furnace is shipped from the factory completely assem­
bled with multispeed direct-drive blower and wired ready for
downflow indoor heating installation only. AU sizes feature
a printed-circuit board control center with easy-to-read, low-
voltage terminal strip to ensure proper connections.
A CAUTION
Do not install furnace in a damp, corrosive, or contami­
nated atmosphere. Make sure all combustion and circu­
lating air requirements listed in “Procedures for
Natural-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 installèd. If
the furnace is required during construction, use clean
outside air for combustion and ventilation. Compoxmds
of chlorine and fluorine 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.
The design of the downflow gas-flred furnace is A.G.A. cer­
tified for installation on noncombustible flooring. The fur­
nace may be installed on combustible flooring when
installed with the accessory floor base. This furnace is for
installation in alcoves, basements, closets, or utility rooms.
This furnace line is
not
A.G.A. design certified for installa­
tion in a mobile home, recreation vehicle, or outdoors.
