Step 7
(A) Measure the distance from the interior wall to the duct splitter.
(B) Line up the 2 halves of the duct insulator to fit together.
(C) Use a blade knife to cut both halves of the duct insulator to the
measured distance.

Step 4
 For 5" Ducting, attach the two insulated 5" ducts from the unit over
the 5" Duct Collar (A). Secure the insulation to the 6" Duct Splitter
Collar Rim (B).
 For 6" Ducting, secure the insulated 6" ducts from the unit over the
6" Duct Splitter Collar Rim (B).

Step 6
(A) Attach the duct splitter over the 6" galvanized duct. Be sure the
pieces align with the holes located in the underside of the duct
splitter and 6" galvanized duct.
(B) Insert and attach the Retainer Screw Assembly until it seats in
the pre-punched hole in the galvanized pipe. The nylon should be
flush with the foam. Screw until secure (3 to 4 turns).

Step 8
(A) Silicone the concave sides of the duct insulator.
(B) Silicone both ends of the duct insulator.
(C) Align the cut ends of the duct insulators towards the exterior wall
and wrap the 2 halves of the insulator around the exposed 6"
galvanized duct.
(D)Secure the duct insulator with the Nylon Cable Tie.
