Leveling Legs (If Desired)

In upflow position with side return inlet(s), leveling legs may be used,

see 

Fig. 10

. Install field-supplied, 5/16 x 1-1/2 in. (8 x 38 mm) (max)

corrosion-resistant machine bolts, washers and nuts.

NOTE: 

Bottom closure must  be  used  when leveling  legs  are  used. It

may be necessary to remove and reinstall bottom closure panel to install

leveling  legs. To  remove bottom closure panel, see Item 1.  in Bottom

Return Air Inlet section.
To install leveling legs:

1. Position furnace on its back. Locate and drill a hole in each bottom

corner of furnace, see 

Fig. 10

2. For each leg, install nut on bolt and then install bolt and nut in hole.

(Install flat washer if desired.)

3. Install another nut on other side of furnace base. (Install flat washer

if desired.)

4. Adjust outside nut to provide desired height, and tighten inside nut

to secure arrangement. 

5. Reinstall bottom closure panel if removed.

DOWNFLOW INSTALLATION

NOTE: 

For downflow applications, this furnace is approved for use on

combustible flooring when any one of the following 3 accessories are

used:

• Downflow combustible floor subbase

• Manufacturer’s approved Cased Coil or Coil Casing

1. Determine application being installed from 

Table 4

.

2. Construct hole in floor per 

Table 4

 and 

Fig. 11

.

3. Construct plenum to dimensions specified in 

Table 4

 and 

Fig. 11

.

4. If downflow subbase is used, install as shown in 

Fig. 12

. If Coil or

Coil Casing, install as shown in 

Fig. 13

.

NOTE: 

It  is  required  that  the  perforated  supply-air  duct  flanges  be

completely  folded  over  or  removed  from  furnace  when  installing  the

furnace  on  a  factory-supplied  cased  coil  or  coil  box.  To  remove  the

supply-air  duct  flange,  use  wide  duct  pliers  or  hand  seamers  to  bend

flange back and forth until it breaks off. Be careful of sharp edges, see

Fig. 17

.
