2. Assemble and Adjust the Sleeve Length

Measure wall thickness through previously drilled 3 1/2 inch (90 mm) hole.

The end of the sleeve should protrude 3/16 - 3/8 inch (5-10 mm) from the outside wall.

In the FOT-203 (Vent Kit A) there are 4 parts provided with which to assemble the sleeve. Use the table to determine which pieces to assemble.

In both kits, two parts are threaded for additional adjustment.

Adjust the sleeve length to wall thickness plus 3/16 - 3/8 inch (5-10 mm).
