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 after configuring coil flanges as required see “Coil Flange” sec- tion 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.

For horizontal left hand applications no conversion is required to an MC coil when used with a downflow/horizontal furnace. A mounting plate, supplied with every coil should always be installed on the side desig- nated as top side. See Figures 4 & 5.

FURNACE ASSEMBLY - PC SERIES COILS

These upflow coils are designed for installation on top of upflow fur- naces only.

If the coil is used with a furnace of a different size, use a 45° transition to allow proper air distribution through the coil.

1.Position the coil casing over the furnace opening as shown in Fig- ure 6.

2.Place the ductwork over the coil casing flange and secure.

3.Check for air leakage between the furnace and coil casing and seal appropriately.

Do not drill any holes or drive any screws into the front duct flange on the coil in order to prevent damaging coil tubing. See Figure 6
