CHIMNEY INSTALLATION

FIRESTOP THIMBLE AND THIMBLE EXTENSION

A firestop thimble is required in the chimney installation of all fireplaces safety-certified for installation in manufactured homes. For shielding purposes, the firestop thimble must pass through the manufactured home ceiling and extend up to the roof line of the manufactured home. See Figures 13 through 15. When an extension is needed, a thimble extension must be installed along with the firestop thimble. Models SVTR and SVTE thimble extensions have been safety-certified for use with this fireplace and should be installed as follows.

1.Lay out, cut and frame a square opening through the ceiling and roof structure at the point where the chimney will pass through. The SVTR firestop thimble requires a 14½"x14½" square opening. If the chimney is to go through a pitched roof, the hole in the roof must be rectangular instead of square. A 7½° pitch requires 14½"x14¾" framing. A 15° pitch requires a 14½"x15" framed opening.

2.Install the SVTR firestop thimble as shown in Figure 13. Nail it securely to the framing members. The firestop thimble should extend completely through the roof structure to shield combustible construction materials. If the SVTE thimble extension is needed, it should overlap the firestop thimble a minimum of 1". Screws should be used to secure the thimble extension to the firestop thimble. See Figure 14.
