Illustration Key
The following safety rules apply to offset
installations. (The letters correspond with
letters above):
A. Height of the chimney measured from
the hearth to the chimney exit at top:
CR36L/R Series
Maximum: 90’0”
Minimum:
Without elbows 14’ 0”
With 2 elbows 15’ 0”
With 4 elbows 21’ 0”
B. Do not use more than four elbows per
chimney.
Attach the straps of the top elbows to a
structural framing member.
The first elbow of any pair does not have
straps.
C. The chimney cannot be more than 30°
from the vertical plane.
D. The maximum length of the angled run
of the total chimney system is 20 feet. (G
plus H cannot exceed 20 feet)
E. A chimney support (Model SKCS8) is
required every 6 feet of angled run of
chimney. Chimney supports are required
at 30 feet and 60 feet of chimney height
above the hearth also.
Determine the offset distance of your chim-
ney arrangement from the centerline of the
fireplace to the centerline of the chimney
where it is to pass through the first ceiling.
NOTE: This offset distance may not be your
full offset distance. See Examples 2 and 3.

Planning Information
Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
Mounting the Fireplace
A fireplace may only be mounted on the following sur-
faces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
The fireplace must be spaced 3/4 inch from a combus-
tible back wall and 7/16 inch from a combustible side
wall or support. (Fig. 17, Page 12)
Planning the Chimney Run
Determine how the chimney will be run, length of run
and chimney components required to complete the
job. (Fig. 3) Never install a chimney below minimum
heights.
The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 5)
The key points of the “Ten Foot Rule” are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10’ (3m) or less, the top of the
chimney must be at least 2’ (610 mm) above the
peak of the roof, but never less than 3’ (914 mm)
in height above the highest point where it passes
through the roof.
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10’ (3 m), a chimney height
reference point is established on the surface of the
roof a distance of 10’ (3 m) from the chimney in a
horizontal plane. The top of the chimney must be
at least 2’ (610 mm) above the reference point, but
never less than 3’ (914 mm) in height above the high-
est point where it passes through the roof.
In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a
vertical plane.
3. A chimney may run straight up or it may be neces-
sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20’ (6 m).
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extend-
ing more than 6’ (1.8 m) above a roof line.
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 20’ (6 m) above the
hearth. Chimney supports are required if the vertical
height exceeds 20’ (6 m). Locate chimney supports
at ceiling holes or other structural framing at 20’ (6m)
heights. Spacing between chimney supports must not
exceed 20’ (6 m). Use Chimney Support Model SKCS8
for SK8 chimney, and Model 11CS for 11CF chimney.
(Note: the chimney support can not be mounted
directly to the fireplace.) Support provided by elbow
straps fulfills the support requirement only if they are
spaced as previously described. (A chimney support is
2¹⁄₂" (64 mm) long when installed.)

Angled chimney runs require a support every 6’ (1.8 m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 6)
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 4, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Majes-
tic Fireplaces dealer for assistance.

Insulating Fireplace Enclosure For
Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fire-
place enclosure to eliminate cold air penetration
as much as possible.
Insulate base of fireplace with a non-combus-
tible insulation rated for a minimum of 300°F.
Insulating is very important for outside wall
installations over a concrete slab. If fireplace
is installed on a platform, insulation should be
placed on top of the platform before fireplace is
set.(Fig. 7)
When a fireplace is installed in a chase or on an
outside wall, enclosure should be treated like
any outside wall in a home. Insulation should
be installed on the inside wall as well as the
outside wall(s). In a chase, it is also a good idea
to install a firestop at the first ceiling level above
the fireplace and enclose the chase with sheet-
ing material. Insulation may then be installed
above sheeting material to assure the space
around the fireplace is totally protected. (Fig. 2)
When installing the chimney, DO NOT caulk
between outer pipe and firestop. It is vital that
some air be allowed to flow through this very
thin gap.
CAUTION: WHEN INSTALLING A FIRE-
PLACE IN AN INSULATED ENCLOSURE, BE
SURE ALL REQUIRED AIR SPACES ARE
MAINTAINED. (Page 12, Fig. 17)

Framing
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
Frame fireplace with 2 x 4 lumber or heavier materials.
Refer to framing dimensions in Figures 1 or 2 for basic
fireplace specifications. Headers and support studs
must be turned on end as illustrated in Figure 2, Page
4.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Chimney Set-up
Since you have already preplanned the chimney run,
you should know exactly how the installation is to be ac-
complished — how much pipe is required, the number
of elbows, if any, and type of termination to be used.
CAUTION: REPORT TO YOUR DEALER ANY PARTS
DAMAGED IN SHIPMENT, SPECIFICALLY CHECK
THE END CONNECTION OF CHIMNEY SECTIONS
AND ELBOWS.
Straight-Up Chimney Installation
To locate the centerline of the flue put the fireplace in
final position and place a plumb bob from the ceiling to
the center of the fireplace flue collar. Mark this spot on
the ceiling. Draw a line through that mark to either side
of the firebox and indicate dimension X to locate the
side wall framing. (Fig. 8) Be sure to observe clearance
requirements for side and parallel combustible walls as
noted in Figure 20, Page 15.

Offset Installation
In order to clear an obstruction, it may be necessary
to offset chimney from vertical. This is accomplished
by using CFM Corporation elbows. Use the 30° Offset
Elbow table on Page 5 to determine proper offset and
parts required.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important to
install the second elbow in each offset as close to the
ceiling or support as possible so the elbow straps can
be secured to framing members to help support the
weight of the chimney.
Determine offset distance of your chimney arrangement
from centerline of fireplace to centerline of chimney
where it is to pass through ceiling.
Locate center point of the chimney on ceiling as though
a straight up chimney arrangement is to be used.
Measure your offset dimension from the chimney center
point on the ceiling.

Ceiling Chimney Hole/
Possible Obstructions
The size of the hole in the ceiling will vary with the
angle at which the chimney passes through ceiling.
Drive a nail up through ceiling at marked chimney
center point. Go to floor above and see where hole
will be cut. Check to see where existing ceiling joists
and other possible obstructions are located...i.e. wiring,
plumbing etc... If necessary, re-position chimney and/or
fireplace to avoid obstructions.
Cutting the Hole
Cover fireplace collar opening and cut proper sized
chimney hole in chimney. The SK8 pipe allows you to
run pipe through a typical 16” on center joist without
cutting joists.
Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure
10. It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.
Positioning, Safety Strips,
Securing the Fireplace
Slide fireplace into position.
Lift the fireplace front slightly and slide the metal safety
strips under front bottom edge about 1¹⁄₂” (38mm), al-
lowing the remainder to extend in front of firebox. Over-
lap strips at least 1/2” (13mm) to provide a positive joint.
(Flat safety strips are packed with fireplace.) (Fig. 11)
Safety strips are used to ensure that any combustible
materials in front of the fireplace are protected even
though a noncombustible hearth extension is required.
If fireplace is to be elevated above the floor, a “Z”
shaped metal safety strip must be fabricated and used
to protect combustible surfaces in front of the fireplace.
This “Z” shaped safety strip is not provided but must
be fabricated of metal with each horizontal leg at least
1¹⁄₂” (38mm) wide and equal in length to the metal strips
provided with the fireplace.
NOTE: Safety strips are not required over noncombus-
tible floors where all supports at the base of the fire-
place are noncombustible.
Outside Air Kit
An outside air kit damper is installed in all CR36L/R
Series Fireplaces. If desired, or if local codes mandate
the use of an air kit, then an AK-MST is required to
complete the installation (from air kit to the outdoors). If
the outside air kit is to be used, the AK-MST Air Termi-
nation Kit MUST be installed BEFORE the fireplace is
enclosed. Refer to the AK-MST instructions for field in-
stallation. NOTE: Outside air control knob can be found
in screen bag.
The inside dimension of the frame must be the same
as the hole size selected from Figure 10 in order to
provide the required 1¹⁄₂” air space between the outside
diameter of the chimney and the edges of the framed
ceiling hole.

Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 13. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
When installing elbows, only outer pipe will snap-
lock. Middle pipes simply slide into position. Be sure
to always attach straps on upper elbow to a structural
framing member. (Fig. 14)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer. Refer to Figure 15 for appropri-
ate spacer orientation.
Installing the Firestop Spacer
in the Ceiling Hole
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer
(at each corner) to the
framing members of the
ceiling hole. NOTE: A
firestop spacer is not
required at the roof.

Hole sizes listed in Figure 10 for angled firestop spac-
ers provide minimum required air space to chimney
pipe for ceiling thickness up to 8” (203mm). When
combined thickness of ceiling material, ceiling joists
and flooring material exceeds 8” (203mm), adjustments
must be made in framing to assure that minimum air
spaces to chimney are maintained.
Proper Firestop Spacer Installation
Page 10, Figure 15 shows different installation proce-
dures for both an area that is an attic and an area that
is not an attic.
If the area above the ceiling is not an attic, position the
firestop spacer with the flange on the ceiling side and
the angled portion extending up into the hole.
If the area above the ceiling is an attic, position the
firestop spacer with the flange on the top of the framed
hole and the angled portion extending down into the
hole.
Firestop spacers are not available for, nor are they
required on vertical walls.
DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you seal
this area, it may cause a fire hazard.
Canadian Requirements for
Insulation Shield
In Canada, an attic insulation shield is required to
prevent attic insulation from contacting the chimney
section. NOTE: If the attic insulation shield is used, the
firestop is not required in the attic installation. Framing
dimensions for the chimney hole should measure 14¹⁄₂"
x 14¹⁄₂" (368 x 368mm) (SK8). An attic shield MUST
be installed on top of attic joists (above the floor level).
(Fig. 16)
NOTE: In the U.S., it is a good idea, although not al-
ways required, to install an attic insulation shield where
blown-in insulation is planned to be used in the attic.
Install the attic insulation shield with the flanges on its
base extending down into the framing hole. Nail each
corner of attic insulation shield to the framing members
of the ceiling hole using 8d nails. Attic shields are not
required at the roof.
Continue Installing Pipe to Complete Run
Continue attaching pipe sections to complete system
to next level always being careful the pipe is firmly
snapped 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 on Page 7, Figure
6. Bend straps as necessary and make sure they are
secure so they will support the weight of the chimney.
A chimney support is 2¹⁄₂" (64mm) 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. A chimney support can-
not be mounted directly to the fireplace.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. Refer to firestop
illustration on Page 10, Figure 15.
Penetrating the Roof
Run pipe to roofline. Since chimney system must be
vented to the out-of-doors, you must use an approved
termination.
If a chase is used, refer to the installation manual pro-
vided 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 the chimney termination to find correct
size of roof hole.
There must be an air space (1¹⁄₂" (38mm) with SK8 )
between outermost portion of chimney sections and
any adjacent combustible surfaces. (Fig. 17) (Com-
bustible surfaces include burnable materials such as:
ceiling members, joists, flooring, combustible insula-
tion and roof structures.)
WARNING: Do not pack required air spaces with
insulation or other materials.
Mark an outline of the roof hole around the center of
the point nail. NOTE: Hole dimensions given in the
chimney top installation instructions are horizontal
dimensions; 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
withstand 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.
Installing Top Housing or Termination
Follow the installation instructions provided with the
CFM Corporation chimney termination you have se-
lected.
Installing Chimney In a Chase
Refer to Page 4, Figure 2 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and
construction of chase may vary with type of build-
ing. 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 CFM Corporation 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. (Black
painted area) (Fig. 17)

Finish Wall
Finish the wall with material of your choice. Do not
install a combustible mantel shelf less than 12”
(305mm) from the top of the fireplace opening. Do
not install a mantel face plate less than 6” (159mm)
from top of fireplace opening. (Fig. 18) If a combus-
tible material is used below a flat mantel shelf, consult
your local building codes for minimum clearance from
top of fireplace opening to bottom of mantel shelf.
When finishing the fireplace, a combustible facing mate-
rial (i.e. drywall or wood paneling) may be installed at
the fireplace surround top as shown in Figure 20. This
material may rest on the ledge brackets (brackets on
the front and side edges of the fireplace), but must NOT
be notched to fit around them. (Fig. 20)
All joints (top, bottom and sides), where the wall or
decorative facing material meets the fireplace surround
must be completely sealed with a noncombustible ma-
terial. (Fig. 17, 18, 20)
Only noncombustible material may be applied as facing
to the black fireplace surround.
When finishing the fireplace, never obstruct or
modify the air inlet grille in any manner.
When finishing the fireplace, use the material of
your choice. If you decide to cover the fireplace sur-
round, noncombustible materials must be used.
Side Wall Protection
All walls constructed closer than 16” (406mm) from the
fireplace opening must be protected with CFM Corpora-
tion Wall Shield Model SP40 or a built-up wall shield
described in Figure 17.
(ANY PERPENDICULAR SIDE WALL MUST NOT BE
CLOSER THAN 40” (1016mm) TO THE OPEN END
OF AN OPEN END FIREPLACE.)
The built-up wall shield design described in Figure 17 is
an alternate method for adding protection to side walls
and can be used in place of the SP40 with the same
wall clearances specified for the SP40.
EXAMPLES OF INSULATION:
1. Manville - CERAFORM 126, K = .27, 1/2” thick re-
quired.
2. CFM Corporation Building Products - EH2416, K =
.458, 1” thick required.
Hearth Installation
A hearth extension is required to protect a combustible
floor in front of the fireplace. Refer to Figure 20 for mini-
mum dimensions and mounting detail.
NOTE: Hearth Extension must not cover the air
inlet opening of a fireplace.
The hearth extension described in Figure 20 must be
a durable non-combustible material with a minimum
(total) Rt value of 1.09; refer to Figure 21 for examples.
The overall height (above a combustible floor), depth
and width must be as indicated, with the extension cen-
tered to the fireplace opening.
The top of the insulation material must be covered with
a noncombustible decorative covering or a piece of
.018” minimum sheet metal, to protect hearth extension
material. (Fig. 23)
Secure the hearth extension to the floor to prevent
shifting, using trim molding or other similar means at
three (3) outer edges. Seal crack between the fireplace
hearth and hearth extension with a noncombustible
material. (Figs. 22,23)
WARNING: HEARTH EXTENSION MUST BE IN-
STALLED IN ACCORDANCE WITH FIGURES 20 AND
21.
Alternate noncombustible materials may be used pro-
viding the (total) thermal resistance (Rt value) of the al-
ternate material employed is greater than or equal to R
= 1.09. Thermal resistance (R) or thermal conductivity
(K), may be obtained from manufacturer of the material.
Factors are related by the formula K = 1/R.
T = given thickness
R = thermal resistance for a given thickness (T)
K = thermal conductivity
Noncombustible material with a lower R value may be
used, provided thickness of material is sufficiently great-
er to maintain an equivalent (total) thermal resistance
(Rt).
Example of Determining Hearth Extension
Equivalents
To determine the thickness required for any new mate-
rial:
NEW K of new material (per inch) thickness
required = X of listed
thickness K of listed material (per inch) material
Example for Common Brick
T (new) = 5.0/0.458 x .5 in. = 5.46 in. (new required
thickness).

Installing Line for Gas Logs
Majestic Fireplaces CR36R/L Series fireplace is de-
signed to accept a 1/2” gas line for an approved gas ap-
pliance. (CFM Corporation manufactures a wide variety
of gas logs for use in Majestic Fireplaces.) Have the
appliance installed by a qualified plumber in accordance
with all building codes. The gas connection enters the
fireplace at the end opposite the open end.
Locate the gas line hole in the outer casing of the fire-
place and remove the insulation from the gas line tube.
(Fig. 24)
From inside the fireplace, locate the knockout on the
firebrick. Using a flat bladed screwdriver or small chisel
and hammer, carefully tap around the knockout until it
loosens and falls out.
Now, install 1/2” certified gas pipe through the open-
ing. After the gas pipe installation is complete, use the
insulation that was removed from the gas line tube
to repack the space around the pipe. This should be
inserted from the outside of the fireplace and packed
tightly to totally seal between the pipe and the tube.
NOTE: The gas pipe should not come in contact
with any wood structures until it has reached a
point at least one (1) inch away from the fireplace
side.
NOTE: Local codes may require removal of flue damper
when installing any type of gas appliance in a fireplace.
The gas pipe installation is intended for connection to
a decorative gas appliance only (1) incorporating an
automatic shutoff device and (2) complying with the
Standard for Decorative Gas Appliances for Installation
in Vented Fireplaces, ANSI Z21.60 or CSA draft require-
ments for Gas-Fired Log Lighters for Woodburning
Fireplaces (Draft No. 4, August 1993).
The decorative gas appliance should be installed in
accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54.
CAUTION: WHEN USING DECORATIVE
GAS APPLIANCE, THE FLUE DAMPER
MUST BE SET IN THE FULLY OPEN POSI-
TION. IF YOU HAVE GLASS DOORS ON
THE FIREPLACE, THEY MUST ALSO BE
FULLY OPENED.
