N. SL-300 Series Ceiling/Roof Thimble

NOTICE: REQUIRED for manufactured homes.

1.Locate the point where the chimney will exit the roof by plumbing down to the center of the chimney. Lay out, cut and frame a 14-1/2 in. (368 mm) square opening (measured on the horizontal) through the ceiling and roof structure.

Consult local codes for framing details.

2.The thimble must extend completely through the roof structure shielding combustible materials. Five location holes have been provided to allow for a variety of ceiling/ roof thicknesses. A Thimble Extension is required when the ceiling/roof thickness exceeds 12-1/2 in. (318 mm). The extension should overlap the thimble one inch.

3.To attach the extension to the thimble, drill 1/8 in. (3 mm) holes through the outer shield of the thimble using the predrilled holes in the extension as guides. Attach the extension to the thimble using the screws provided with the extension.

4.Install the thimble assembly and nail it securely to the fram- ing members.

5.Center the flashing over the chimney and nail it to the roof using the Stormguard nails provided. Keep gaps between the flashing plate and the roof to a minimum. Caulk the flash- ing plate and roof junction as well as the vertical seam on the flashing. All nail heads must be caulked with a roofing sealant.

6.Finish assembling the chimney storm collar and termina- tion cap following the installation instructions provided with them.
