CEILING SUPPORT
FRAMING DETAILS:
To complete a proper Decorator Ceiling Support installation, the
following parts will or may be required:
- Decorator Ceiling Support (DCS): Required when supporting a
chimney through a flat level ceiling.
-Stove Pipe Adaptor (ASE): Transition from the chimney to flue
pipe.
- Attic Insulation Shield (AIS): Required where a chimney passes
from a lower living space into an unoccupied attic space.
- Firestop Joist Shield (FRS): Required where a chimney passes from
a lower living space into an upper living space or occupied attic
space.
- Roof Flashing Assembly (including Storm Collar): Required when
the chimney penetrates a roof.
INSTALLATION PROCEDURES:
The SuperVent/SuperPro Ceiling Support will support up to 50 feet
of chimney sections, all of which must be installed above the
support. Figures 4 & 7 show the 2 most common types of Ceiling
Support Installation. Frame (on all 4 sides) a level square opening to
the dimensions specified in the Framing Dimension Table 1.
Slide the Trim Ring onto the Ceiling Support and slide the assembly
into the framed opening from below. Ensure that the finishing ring
is flush with the underside of the ceiling and the assembly is level and
plumb. Secure the ceiling support in place using at least three (3) 8-
penny (2-1/2") nails through each of the 4 straps or through the 12
prepunched holes in the support. You may substitute in lieu of nails
12 - #8 x 2" wood screws.

Note: *When cutting the inside "finished" surface of your wall or
ceiling cut a "round hole" for the framing dimension and not a square
hole; i.e.: 14" x 14" would be a 14" round opening.
STOVE PIPE ADAPTOR
The Stove Pipe Adaptor (ASE) is installed by twist-locking it into
the bottom end (female end) of the first Chimney Section that enters
the Ceiling Support. Do not install an elbow in the Ceiling Support.
Make sure that the male coupler of the insulated Chimney Length is
pointing upwards as indicated by the arrow on the chimney label.
Lower the assembly down into the Decorator Ceiling Support
ensuring that the Stovepipe Adaptor sleeve is protruding through
the support and into the living space (see Figure 5).
The crimped end (stub) of the Stove Pipe Adaptor is intended to fit
inside of the flue pipe from a solid fuel appliance, thus preventing
condensate drips at the chimney connection. Install inter-connecting
Plan your installation carefully. If possible, position the stove so
that the flue outlet is between joists or rafters. Drop a plumb line to
the center of the flue outlet and mark this center point on the ceiling.
Lay out and frame in all openings ensuring the specified 2” clearance
to combustibles is maintained. Refer to Table 1 and applicable
Tables for framing dimensions and mark the appropriate cutting lines
around the center point. All openings should be square (all four
sides), plumb and in perfect alignment with each other (see figure 2).
For sloping roofs (cathedral/vaulted ceiling), ensure that the framing
dimension is measured in the horizontal plane (see figure 3).
