INTRODUCTION
Before installing the furnace, refer to “Procedure for
Induced-Combustion 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. 54-1984/ANSI Z223.1-
1984.
The induced-combustion 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 No. 54-1984/ANSI Z223.1-
1984), Part 7.14.3.b. This furnace is also hsted by A.G.A. 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 completely assem­
bled with multispeed direct-drive blower and wired ready for
indoor heating installation. All sizes feature a blower con­
trol 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 insteJled operation may vary,
depending on installation, weather, or other factors.
