A decorative ceiling thimble can be installed on a at ceil-
ing through which the vent passes. The decorative ceiling
thimble is used to cover the restop.
• Seal the gap between the vent pipe and restop using
high temperature silicone to prevent cold air inltration.
• Install the decorative ceiling thimble by sliding it up to
the ceiling and attaching it using the provided screws.
A decorative cathedral ceiling support box can be installed
on a cathedral ceiling through which the vent passes.
• Use a plumb-bob to mark the center line of the venting
system on the ceiling and drill a small hole through the
ceiling and roof at this point. Locate the hole and mark
the outline of the cathedral ceiling support box on the
outside roof.
• Remove shingles or other roof covering as necessary to
cut the rectangular hole for the support box. Cut the hole
3 mm larger than the support box outline.
• Lower the support box through the hole in the roof until its
bottom is at least 2 in. (51 mm) below the ceiling (Figure
10.9).

• Level the support box both vertically and horizontally and
temporarily tack it in place through the inside walls into
the roof sheathing.
• Use tin snips to cut the support box from the top corners
down to the roof line and fold the resulting aps to the
roof. See Figure 10.10.
• Nail the aps to the roof AFTER running a bead of non
hardening sealant between the aps and the roof.
WARNING! Risk of Fire! Clean out ALL materials from
inside the support box and complete the vertical vent run
and termination.
