Gas-Fired Counterflow Furnace
INTRODUCTION
Before installing the furnace, refer to “Procedure for Gas
Furnace Installation” (packaged with the furnace) for infor­
mation concerning combustion, venting, piping, and other
standard installation practices. Further reference is made to
the current edition of the American National Standard
Z223.1 National Fuel Gas Code. This publication covers in­
stallation, startup, and maintenance.
The Model 58DE Counterflow Gas-Fired Furnaces are
shipped from the factory completely assembled and internal­
ly wired ready for indoor heating installation. The air condi­
tioning models have a low-voltage terminal strip for con­
venience of field wiring.
The design of the 58DE Gas-Fired Furnaces is A.G.A. cer­
tified for installation on combustible flooring (with use of
optional combustible floor base) in alcoves, closets, or utility
rooms; with either natural or liquefied petroleum gas.

V. ELECTRICAL CONNECTIONS
A. Line-Voltage Wiring
IMPORTANT : Before proceeding with the electrical connec­
tions, make certain that voltage, frequency, and phase cor­
respond to that specified on the unit rating plate. Also, check
to be sure that the service provided by the utility is sufficient
to handle the additional load imposed by this equipment. Re­
fer to the unit rating plate for equipment electrical require­
ments.
l^ecíssesí to «Itet.
Use a separate branch electrical circuit for this furnace. A
disconnecting means must be located within sight of, and
within 50 feet of, the furnace.
B. Low-Voltage Wiring
See Figure 3 for wiring diagram showing the proper field
low-voltage wiring. Make all electrical connections in ac­
cordance with the National Electrical Code and any local
codes or ordinances that might apply.
