Downflow/Horizontal Induced-Draft

Gas Furnace

GENERAL

Before starting installation of this furnace, read
these instructions carefully and completely. After
installation is complete, remove the Energy Guide
tag from the furnace. Also read the Procedures for
Induced-Draft Gas-Fired Furnaces (packaged with
furnace) for important information concerning
combustion, venting, piping and other standard
installation practices. Further reference can be made
to the current edition of the American National
Standard Z223.1 National Fuel Gas Code.

The induced-draft vent system of this furnace is
designed to operate at zero or negative pressure at
the vent connector outlet. This furnace, therefore,
complies with the National Fuel Gas Code (NFPA
54-1980 or ANSI Z223.1-1980), Part 7.14.3.b. This
furnace is also listed by AGA for use with the type
B1 gas vent, as described in the National Fuel Gas
Code, Part 7.3.2.

Each furnace is shipped from the factory com
pletely assembled with multispeed direct-drive
blower, and wired ready for indoor heating installa
tion. All sizes feature a blower control center with
easy-to-read low-voltage terminal strip to ensure
proper connections.

The output capacity and any representations of
efficiency for this product are based on standard
Department of Energy test procedures. The installed
operation may vary, depending on installation,
weather and other factors.
