If duct flanges are not removed, bent up, or bent over morethan 120°, airflow across heat exchangers will be affected.This may cause limit cycling or premature heat exchangerfailure.Step 3—Horizontal InstallationDo not install the furnace on its back or hang furnace withcontrol compartment facing downward. Safety control opera-tion will be adversely affected. Never connect return-air ductsto the back of the furnace. Failure to follow this warningcould result in fire, personal injury, or death.The furnace can be installed horizontally in an attic or crawl spaceon either the left-hand (LH) or right-hand (RH) side. The furnacecan be hung from floor joists, rafters or trusses or installed on aplatform, non-combustible blocks, bricks or pad.SUSPENDED UNIT SUPPORTThe furnace may be supported under each end with threaded rod,angle iron or metal plumber’s strap as shown. (See Fig. 15 and 16.)Secure angle iron to bottom of furnace as shown. Heavy-gaugesheet metal straps (plumber’s straps) may be used to suspend theunit from each bottom corner. To prevent screws from pulling out,use 2 # 8 x ¾-in. screw into the side and 2 # 8 x ¾-in. screw in thebottom of the furnace casing for each strap. (See Fig. 15 and 16.)PLATFORM UNIT SUPPORTConstruct working platform at location where all required furnaceclearances are met. (See Fig. 2 and 17.) For furnaces with 1-in.clearance requirement on side, set unit on non-combustible blocks,bricks or angle iron. For crawlspace installations, if the unit is notsuspended from the floor joists, the ground underneath unit mustbe level and the unit set on blocks or bricks.ROLL-OUT PROTECTIONProvide a minimum 17 3/4″ X 22″ piece of sheet metal for roll-outprotection in front of burner area for units closer than 12 inchesabove the combustible deck or suspended units closer than 12-in.to joists. The sheet metal MUST extend underneath the furnacecasing by 1 in. with the door removed.The bottom closure pan on furnaces of widths 17 1/2 in. and largermay be used for roll-out protection when bottom of furnace is usedfor return air connection. See Fig. 17 for proper orientation ofroll-out shield.Step 4—Filter ArrangementThere are no provisions for an internal filter rack in these furnaces.An external filter rack is required.Table 3—Opening Dimensions (In.)FURNACECASINGWIDTHAPPLICATION PLENUM OPENING FLOOR OPENINGA B C D14–3/16Upflow Applications on Combustible or NoncombustibleFlooring (KGASB subbase not required) 12-11/16 21-5/8 13-5/16 22-1/4Downflow Applications on Noncombustible Flooring(KGASB subbase not required) 12-9/16 19 13-3/16 19-5/8Downflow applications on combustible flooring (KGASBsubbase required) 11-13/16 19 13-7/16 20-5/8Downflow Applications on Combustible Flooring with CD5 orCK5 Coil Assembly or KCAKC coil box (KGASB subbasenot required)12-5/16 19 13-5/16 2017–1/2Upflow Applications on Combustible or NoncombustibleFlooring (KGASB subbase not required) 16 21-5/8 16-5/8 22-1/4Downflow Applications on Noncombustible Flooring(KGASB subbase not required) 15-7/8 19 16-1/2 19-5/8Downflow applications on combustible flooring (KGASBsubbase required) 15-1/8 19 16-3/4 20-5/8Downflow Applications on Combustible Flooring with CD5 orCK5 Coil Assembly or KCAKC coil box (KGASB subbasenot required)15-1/2 19 16-1/2 2021Upflow Applications on Combustible or NoncombustibleFlooring (KGASB subbase not required) 19-1/2 21-5/8 20-1/8 22-1/4Downflow Applications on Noncombustible Flooring(KGASB subbase not required) 19-3/8 19 20 19-5/8Downflow applications on combustible flooring (KGASBsubbase required) 18-5/8 19 20-1/4 20-5/8Downflow Applications on Combustible Flooring with CD5 orCK5 Coil Assembly or KCAKC coil box (KGASB subbasenot required)19 19 20 2024-1/2Upflow Applications on Combustible or NoncombustibleFlooring (KGASB subbase not required) 23 21-1/8 23-5/8 22-1/4Downflow Applications on Noncombustible Flooring(KGASB subbase not required) 22-7/8 19 23-1/2 19-5/8Downflow applications on Combustible flooring (KGASBsubbase required) 22-1/8 19 23-3/4 20-5/8Downflow Applications on Combustible Flooring with CD5 orCK5 Coil Assembly or KCAKC coil box (KGASB subbasenot required)22-1/2 19 23-1/2 2010
