2. Cut the rough opening into the wall at the desired location using the octagon shaped cardboard template that was provided with the window. Use caution concerning any electrical wiring or plumbing issues that may be hidden inside the wall.

 

3. Prepare framing rough opening (See illustration #1). OPENING SIZES OCTAGON - 24" x 24" or 20 3/8" x 20 3/8" depending on the model ELONGATED - 24" x 35 1/2"

Figure 1
Important: Framing members must be square, plumb, and level, so window will set squarely in opening.

 

4. If you are installing a venting window, do not open sash until step # 11.

 

5. From the outside, place window into the rough opening. Center the window in the opening and partially nail one 16d finishing nail (not included) through the very top piece of the window frame's exterior casing to hold the window in place. Then from the interior side of the opening, mark the locations where the four angle studs will be positioned between the four corners of the square frame rough opening and the four angled sides of the window frame (See illustration #2).

 

Important: The inside edge of the window frame should be flush with the interior wall surface. If a larger window frame depth is required, contact the retailer where you purchased the window to inquire about our 2" jamb extender kit which will accommodate a wall thickness up to 6 9/16".

6. Remove the 16d finishing nail and remove the window from the rough opening and then install the four angle studs into the square rough opening where you marked their positions in step 5.

 

7. Apply a 6” wide strip of black impregnated building paper or polyfilm (not included) onto the exterior rough sheathing and wrap around and onto all studs. This will serve as a moisture barrier.

 

8. Apply a bead of exterior clear silicone caulking (not included) all around on the backside surface of the window's exterior casing.

 

9. From the outside, position the window back into the rough opening and once again partially nail back in the 16d finishing nail through the very same top piece of the window frame's exterior casing to hold the window in place.

 

10. From the interior side of the window opening, install some wood shims (not included) between the window frame and studs all around until the window is plumb and level. Now double check again to make sure the inside edge of the window frame is flush with the interior wall surface.

 

11. If installing a venting model octagon window, now open and close the window to check for proper operation.

 

12. Now completely nail in the one 16d finishing nail that was holding the window in place. Then nail one 16d finishing nail completely in on each of the remaining sides of the window frame's exterior casing. Check the plumb and level of the window after each nail you put in.

 

13. Apply a bead of exterior clear silicone caulking (not included) all around the window frame where the exterior casing comes in contact with the building paper or polyfilm. This will prevent water leakage into the wall. Then apply and secure a piece of aluminum head flashing (not included) on the top three sections of the window frame's exterior casing. This will help protect water from running down in behind the exterior casing.

 

14. Apply the exterior siding of choice (not include) around perimeter of the window.

 

15. Apply a bead of exterior clear silicone caulking (not included) between the exterior siding and the window frame's exterior casing.
