DUCT FLANGES

Four flanges are provided to attach ductwork to the furnace. These flanges are rotated down for shipment. In order to use the flanges, remove the screw holding an individual flange, rotate the flange so it is in the upward position and reinstall the screw then repeat this for all 4 flanges.

If the flanges are not used, they should remain in the rotated down posi- tion as shipped.

DUCTWORK INSTALLATION AND SUPPLY PLENUM CONNECTION - UPFLOW/HORIZONTAL

Attach the supply plenum to the furnace outlet. The use of an approved flexible duct connector is recommended on all installations. This connection should be sealed to prevent air leakage. The sheet metal should be crosshatched to eliminate any popping of the sheet metal when the indoor fan is energized.

FLOOR BASE AND DUCTWORK INSTALLATION - DOWNFLOW

Installations on combustible material or directly on any floors must use a combustible floor base shown in Figure 8, "Combustible Floor Base Accessory". Follow the instruc- tions supplied with the combustible floor base accessory. This combustible floor base can be replaced with a match- ing cooling coil, properly sealed to prevent leaks. Follow the instructions supplied with the cooling coil cabinet for install- ing the cabinet to the duct connector. Plug intake and vent pipe holes in bottom panel and move grommet to desired vent side exit.

FURNACE ASSEMBLY - MC & FC SERIES COILS

These coils are factory shipped for installation in either upflow or down- flow applications with no conversion.

Position the coil casing over or under the furnace opening as shown in Figure 2, "Vertical Applications" after configuring coil flanges as required see “Coil Flange” section below.

COIL FLANGE INSTALLATION

The coils include removable flanges to allow proper fit up with furnaces having various inlet and outlet flange configurations. The two flanges are attached to the top of the coil in the factory during production. For proper configuration of flanges refer to Figure 3, "Coil Flange".

Downflow Air Conditioning Coil Cabinet

The furnace should be installed with coil cabinet part number specifi- cally intended for downflow application. If a matching cooling coil is used, it may be placed directly on the furnace outlet and sealed to pre- vent leakage. For details of the coil cabinet dimensions and installation requirements, refer to the installation instructions supplied with the coil cabinet.

Attach the air conditioning coil cabinet to the duct connector, and then

position the furnace on top of the coil cabinet. The connection to the fur- nace, air conditioning coil cabinet, duct connector, and supply air duct must be sealed to prevent air leakage.

COIL INSTALLATION

On all installations without a coil, a removable access panel is rec- ommended in the outlet duct such that smoke or reflected light would be observable inside the casing to indicate the presence of leaks in the heat exchanger. This access cover shall be attached in such a manner as to prevent leaks.
