COUNTERFLOW GAS-FIRED
FORCED-AIR FURNACE
INTRODUCTION
Before installing the fiimace, refer to "Procedure for Gas-
Fired Furnaces” (packaged with the equipment) for informa­
tion concerning combustion, venting, piping, and other stan­
dard installation practices. Further reference is made to the
ciurrent edition of the American National Standard Z223.1
National Fuel Gas Code.
Each furnace is shipped from the factory completely assem­
bled with multispeed direct-drive blower and wired ready for
counterflow indoor heating installation only. All sizes
feature a printed-circuit board control center with easy-to-
read, low-voltage terminal strip to ensure proper connec­
tions.
The efficiency rating of the furnace is a product thermal
efficiency rating determined under continuous operating
conditions independent of any installed system.
CAUTION: Do not install furnace in a corrosive or contami­
nated atmosphere. Make sure all combustion and circulating
air requirements listed in "Procedure for Gas-Fired Fur­
naces” are adhered to, in addition to, all local codes and
ordinances.
The design of the counterflow gas-fired furnace is A.G.A. cer­
tified for installation on combustible flooring (with optional
floor base), in alcoves, basements, closets, or utility rooms.
This furnace line is
not A.G.A. certified for installation in a
mobile home, recreation vehicle, or outdoors.

V. SUPPLY-AIR PLENUM INSTALLATION
A. Installation on a concrete slab
1. See Figure 2 for dimensions and location of supply-air
opening in furnace bottom.
2. Construct hole in floor per dimensions in Figure 3 eind
Table IV.
3. Place plenum and furnace as shown in Figure 4.
B. Installation on a combustible floor
1. Read Installation Instructions packaged with combusti­
ble floor base.
2. Cut and frame hole in floor per dimensions in Table I of
Installation Instructions packaged with combustible floor
base. If this requires cutting of a floor joist, tie ends of cut
joist into adjacent joists so that proper floor support will be
maintained.
3. Assemble and install combustible floor base per instruc­
tions packaged with base.
4. When completed, combustible floor base, plenum, and
furnace (or coil casing when used) should be installed as
shown in Figure 6.
