Carrier 58DH - Manual (Page 5)

Crawl Space Installation — The Model 58DH
furnace can be installed horizontally with either
the left-hand or right-hand side up. In crawl space,
furnace can either be hung from floor joist or in­
stalled on suitable blocks or pad. Furnace can be
suspended from each corner by hanger bolts (use
four 3/8-in. all-thread rods cut to desired length,
1 X 3/8-in. flat washer, 3/8-in. lock washer, and
3/8-in. nut). Dimples are provided for hole loca­
tions. See Fig. 3.
Crawl space installation is very similar to attic
installation. Refer to Horizontal Attic Installation,
Install Furnace (Steps 1,2,3). Installation of sheet
metal shield in front of louvered control panel is
covered in Step 4. For crawl space installation, the
same size sheet metal shield must be installed above
louvered control panel. When installing furnace in
horizontal position in a crawl space, extend sheet
metal shield over furnace top sufficiently to cover
gas pipe entry hole.
Filter Arrangement — Two factory-supplied
filters are shipped in blower compartment. After
return air duct has been connected to furnace, install
filters in a V-formation inside return air plenum.
See Fig. 10 and Table 5 for horizontal applications.
See Fig. 11 for downflow applications.
Accessory filter retainer and duct flange kits are
available. See Fig. 9 and 10 for typical installations.
