Firestop spacers are not available for, nor are they
required on, vertical walls.
The Majestic Fireplaces' chimney components have
been tested and approved with the area where the
outer pipe slides through the firestop spacer sealed
with a noncombustible caulk if desired, or left com-
pletely open with no sealant.
Continue Installing Pipe to Complete Run
Continue attaching pipe sections to complete system to
next level always being careful that the pipe is firmly
snap locked in place before proceeding to next pipe
section.
Chimney Supports
If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to
adjacent structural framing, as shown in Figure 7, Page
7. Bend straps as necessary and make sure they are
secure so they will support the weight of the chimney. A
chimney support is 2
¹⁄₂
" long when installed. Consider
this dimension when determining how many straight
chimney sections are needed.
Note: Chimney supports are generally used in long
runs in a chase installation.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. See firestop
illustration on Figure 16, Page 12.
Penetrating the Roof
Run pipe to roofline. Since chimney system must be
vented to the out-of-doors, you must use an approved
Majestic termination.
If a chase is used, refer to the installation manual
provided with the termination cap.
Locate Chimney Centerpoint On Roof
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney
termination installed. Refer to installation instructions
provided with Majestic chimney termination to find
correct size of roof hole.
There must be a 2 inch air space between outermost
portion of chimney sections and any adjacent combus-
tible surfaces. (Combustible surfaces include burnable
materials such as: ceiling members, joists, flooring,
combustible insulation and roof structures.)
WARNING: DO NOT PACK REQUIRED AIR
SPACES WITH INSULATION OR OTHER MATE-
RIALS.
Mark an outline of the roof hole around the centerpoint
of the nail. Note: Hole dimensions given in the chim-
ney top installation instructions are horizontal dimen-
sions; therefore, the hole size must be marked on the
roof accordingly.
Cover the opening of the installed chimney so debris
cannot get into the system.
Cut and frame the hole. It is good practice to use
framing lumber that is the same size as the rafters.
Install the frame securely because the chimney top and
flashing anchored to the frame must be able to with-
stand heavy winds.
Install Remainder of Chimney Sections
Since you have already preplanned the height of your
termination according to the
Ten Foot Rule, continue to
install pipe to the predetermined height.
Check the chimney top installation instructions for
details on how high above the roof top the chimney
sections (all pipes) should extend.
6. Installing Top Housing or Termination
Follow the installation instructions provided with the
Majestic chimney termination you have selected.
Installing Chimney In a Chase
Refer to Figure 2, Page 4 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and con-
struction of chase may vary with type of building.
These instructions are not a substitute for local building
codes. You must check your local building codes to
determine specific requirements for your city or state.
Note: Other building materials may be required in
addition to Majestic Firestop Spacers.
Finishing
CAUTION: All joints between the finished wall and the
fireplace surround (top/sides) must be sealed with
noncombustible material to prevent cold air leakage
into the room. Only noncombustible material may be
applied to the facing of the fireplace surround. (Fig. 1
