INSTALLATION OF TRANSITION COLLAR
1.Apply the foam gasket included in the kit to the top flange of the Transition Collar.
INSTALLATION OF DUCT EXTENSION KIT
1.Install two No.8 screws provided into the top flange of the Main Duct, at the extension end. Do not tighten the screws. Leave enough space for one thickness of duct material (about the thickness of a credit card) between the flange and the screw head. See figure below.
2.Position the Transition Collar under the Main Duct. Install the collar as shown below. Ensure the oblong holes in the tabs on the Transition Collar are correctly aligned with the corresponding holes in the bottom of the Main Duct. Ensure the collar is correctly aligned with the air discharge opening on the front cover.

IMPORTANT NOTE: Total length of duct extension assembly, including any field supplied duct between main and extension duct, should not exceed 15 effective feet (according to ASHRAE standards).
For steps 2‐4 reference Installation Dimensions and Minimum Clearance drawing on page 2
2.In the room where the Main Duct kit is attached to the Wall sleeve, cut a hole in the wall at the same height from the floor that the Main Duct is located. Cut the hole 1/8" larger than the width and height (1 0" x 5") dimensions of the Duct Extension. TIP: Use a long spirit level to transfer the cut‐out position exactly based on the position of the Main Duct.
3.Measure from the end of the Main Duct where the extension will be connected to the hole in the wall. If necessary, cut the Duct Extension to a length where the cut end protrudes into the wall's inner space and one inch from the adjoining room's wall surface.
4.Insert the Duct Extension into the opening in the wall. Install the Duct Extension by placing the slotted flange over the two screws in the Main Duct. Using two No.8 screws, mount bottom of Duct Extension to Mounting Bracket through the bracket slots.
