It is very important to properly install the hot air discharge components (louvers and blank cover panels)
to direct the flow of air from the furnace. As you will note from Figures 3I and 3J, the air discharge
panels are to be installed on the side(s) and/or bottom of the furnace.
The air flow may be directed
down, front, or back, depending upon how the louvers and cover panels are installed.
IMPORTANT NOTE FOR CENTRAL FURNACE APPLICATIONS:
•
For ducting applications of .25 static pressure,
install the louvers as described in
the following procedure, and then install the ductwork
over top
of the fully open louvers.
•
For ducting applications of .30 (CB-1750) or .40 (CB-2500 and CB-3250) static pressure,
DO NOT install the louvers. The ductwork should be installed directly over the desired air
discharge openings on the side of the furnace cabinet.
•
Ductwork must be installed over side opening(s) ONLY.
Ductwork may NOT be
installed over the bottom air discharge opening.
1.
Refer to Figures 3I and 3J. Determine the desired air flow discharge pattern. Note that each
furnace is supplied with (2) louver sections and (4) blank cover panels.
Air discharge openings are: (1) on each side of the furnace, and (1) on the bottom of the furnace.
2.
Install the louver panels in the desired location(s) with the self-tapping screws provided. Holes
are pre-drilled in the furnace cabinet to accommodate installation of the panels.

NOTE:
Bottom louver installation
applies to Unit Heater furnaces ONLY.
Ductwork for Central Furnace applications
may NOT be installed over the bottom
opening.
•
When determining the
placement of the air discharge
louvers, you also need to consider
the
required clearances from
combustibles
as stated in
Section 4 of this manual.
• Note that each furnace model
supplied with (2) louver sections
which may be installed
together
on one side or the bottom as
shown here OR the louvers may be
split
for partial air discharge on each
side and/or bottom as shown in
Figure 3J
.
