Owner's Manual
- On vertical installations the Trim Plate (TP), Trim Ring (TR), Ceiling Support
(CS), Round Support (RDS), Square Support (SS), and Attic Radiation
Shield (AS) can all be used as firestops.
Supports
EXCELDirect
®
has different supports for different applications. For
convenience, some supports also act as firestops to optimize your installation.
The "EXCELDirect
®
TECHNICAL SPECIFICATIONS" section on page 2
shows the maximum support capacity table for each type of support. Here are
different types of installation with supports.
Ceiling Support / Firestop (CS)
Pass the venting through the support and then fix the support to the pipe
with the three tabs that were previously bent downwards. Use the screws
provided.
Round and Square Support / Radiation Shield (RDS & SS)
The Round Support or Square Support / Radiation Shield are used when the
venting system is not enclosed and a visual effect is desired (e.g. a
freestanding gas stove). These supports are installed from below. Figure 14
shows an example. Screw the support to the framed joist with four #8 x 1 1/2"
wood screws or use the support collar supplied with the Round Support. The
supports are designed to project below the ceiling for a visual effect into the
room
(1/4” below the ceiling minimum).
Place the Finish Trim around the
support and fasten it to the ceiling using the screws provided.
Note
:
When the Round Support / Radiation Shield is used, the framing in the
ceiling can be square as previously described, but the drywall cut in a circle.
The Ceiling Support/Firestop can be used on
any floor level. It is the best choice when a
structure hides the venting system (enclosed
chimney).
Cut and frame a hole to the rough opening
dimensions shown in the table on Page 2. Screw
the corners of the support to the framing from
below with four #8 x 1 1/2" wood screws.
Bend the three tabs in the center of the opening
downwards, into the room. Then, using another
four #8 x 1 1/2" wood screws, attach the Ceiling
Support to the framing through the vertical
spacers as shown in Figure 13.
