AIR DISTRIBUTION SYSTEMS

For proper air distribution, the supply duct system must be designed so that the static pressure measured external to the furnace does not exceed the listed static pressure rating shown on the furnace rating plate.

Three typical distribution systems are illus- trated in Figure 2. Location, size, and number of registers should be selected on the basis of best air distribution and floor plan of the home.

DUCT CONNECTOR SELECTION

PLATINUM SERIES

a. For Platinum ready construction use the 14” round plenum, p/n: 903896.

NON-PLATINUM SERIES

a. Determine depth of floor cavity from surface of floor to top of supply air duct (See Figure 3).

b. Select appropriate model from Table 5 which matches X-dimension of the floor

10

cavity. To maximize air delivery, re- move reducer “C” (see Figure 5) to obtain the largest open area that will fit the duct/floor construction.

DUCT INSTALLATION

Required floor, ceiling, and roof cut-out open- ings must be carefully located to avoid mis- alignment of the furnace (see Figures 6 & 7). Installation procedures are suggested for typi- cal furnace installations and need not be fol- lowed in the exact listed sequence.

CUT OUT FLOOR OPENING & FUEL LINE HOLE

a. Determine center of closet or alcove (Fig- ures 7 & 8).

b. Locate center of the floor opening, mea- sured 10" from the rear wall, and mark cut- out measuring approximately 14-1/2" by 14- 1/2" (± 1”) for model duct connector used (refer to Figures 4 & 5).

c.Locate center of gas line hole, measured 23- 1/4" from the rear wall and 6-5/8" to the left of center of the floor cut-out (See Figure 6) or
