Mounting Supports

Model SCE requires six support locations. See FIGURE 3 .

Supports available from the manufacturer (P/N 74487) or eld-fabricated legs as illustrated in

FIGURE 4 may be used at the four corner support locations. Do not use this type of support

at the center support locations (between the furnace and the blower section). At the center

locations, a eld-fabricated, angle-iron brace support must extend horizontally, jointly sup-

porting a portion of both the furnace and the blower cabinet. All supports must be non-

combustible.

Support Locations

Field-supplied supports between

the blower cabinet and the furnace

must extend horizontally support-

ing both sections.
