nent parts have been highly tested and will operate
safely when installed in accordance with instructions
provided in this manual. Carefully read and understand
all instructions before beginning installation.
If you notice any damage to fireplace or component
parts, immediately report damage to your Majestic
Fireplaces dealer.
Only use CFM Specialty Home Products components
or the warranty will be voided and a fire hazard may be
created.
CFM Specialty Home Products warranty will be voided
by and CFM Specialty Home Products disclaims any
responsibility for the following actions:
•Installation of any damaged fireplace or
chimney component;
•Modification of fireplace, chimney assembly
or any component parts thereof; (except for

Top installation instructions).
•Installation other than as instructed by CFM
Specialty Home Products; or
•Installation and/or use of any component part
not manufactured or approved by CFM Spe-
cialty Home Products in combination or
assembly with a Majestic Fireplaces fireplace
system, notwithstanding any independent
testing laboratory or other third party ap-
proval of such component parts or accessory.
Any such action may possibly cause a fire hazard.
Consult local building codes to ensure that you are in
compliance before installing the fireplace.
Fireplaces must be vented to the out-of-doors.
Do not obstruct or modify air inlets/outlets in any
manner.
Do not install combustible materials on any of the
black fireplace surround.
Burn only solid wood fuel or gas logs.
Do not install a solid fuel burning insert or other

ucts of combustion of such fuels, contain chemicals
known to the State of California to cause cancer,
birth defects and other reproductive harm.
California Health & Safety Code Sec. 25249.6
Drafts
The fireplace should not be located in areas that create
drafts (ie: frequently opened doors and central heating
air inlets/outlets) that hamper the normal flow of air into

C. The chimney cannot be more than
30˚ from the vertical plane in any
installation.
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 11CS) is
required every 6 feet of angled run of
chimney. Chimney supports are
required for every 30 feet and 60 feet
chimney height above the hearth.
Determine the offset distance of your
chimney arrangement from the center-
line 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

Planning Information
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. 8)
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' (610mm) above the peak
of the roof, but never less than 3' (914mm) 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' (3m), a chimney height
reference point is established that is on the surface
of the roof a distance of 10' (3m) from the chimney in
a horizontal plane. The top of the chimney must be at
least 2' (610mm) above the reference point, but
never less than 3' (914mm) in height above the
highest 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 degrees
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 feet.
5. No more than 2 offsets (4 total 30˚ elbows in) per
fireplace may be used.
6. A guy wire stabilizer is required for chimneys extend-
ing more than 6 feet above a roof line.
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
surfaces:
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 3/4 inch from a combustible side
wall or support. (Fig. 20, Page 14)
Planning the Chimney Run
Determine how the chimney will be run, length of run
and chimney components required to complete the job.
(Fig. 6) Never install a chimney below minimum
heights.

Installation
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30 feet above the
hearth. Chimney supports are required if the vertical
height exceeds 30 feet with 11CF chimneys. Locate
chimney supports at ceiling holes or other structural
framing at 30 foot heights. Spacing between chimney
supports must not exceed 30 feet. Use Chimney
Support Model 11CS. (NOTE: The 11CS 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" long when installed.)
Angled chimney runs require a support every six (6)
feet in addition to the elbow straps. Chimney supports
are used for this function. (Fig. 9)
Chase Installation
A chase is a vertical boxlike 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 5, Fig. 5)
If you need help in determining fireplace location or how
the chimney system should be run, contact your
Majestic 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 the fireplace
enclosure to eliminate cold air penetration as much
as possible.
Insulate base of fireplace with a noncombustible
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. 10)
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 sheeting material. Insulation may
then be installed above sheeting material to assure
the space around the fireplace is totally protected.
(Fig. 5)
CAUTION: WHEN INSTALLING A FIREPLACE IN
AN INSULATED ENCLOSURE, BE SURE ALL
REQUIRED AIR SPACES ARE MAINTAINED.

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 - 4 for basic
fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Firebrick Installation
For the SHR52 model the firebrick is packed separately
and must be installed in the fireplace.
You will need four (4) firebrick, three (3) brick retainers,
a phillips head screwdriver, and the grate.
The side and rear firebrick each have a notch in the top
of the brick panel. The side firebrick have a notch in the
lower front side of each panel. The herringbone pattern
faces out of the fireplace always. (Fig. 11)
NOTE: The screens and screen rod smoke baffle
assembly must be removed and set aside before
proceeding. Remove the two screws holding the
screens place. There are seven screws holding the
screen rod smoke baffle in place.
1. Remove the three brick retainers from the combus-
tion dome by removing the phillips screws, set aside.
2. Set the left firebrick in place on the left side of the
fireplace.
3. Slide the rear firebrick back into the left corner
behind the end of the left firebrick. Push both panels
back as far as possible into the left side and corner.
4. Swing the right side of the back firebrick into place.
Attach the left brick in place using a brick retainer at the
top and phillips screw removed earlier.
5. Slide the right firebrick into place as far back as
possible. Attach rear firebrick and right firebrick using
brick retainers and phillips screws removed earlier.
6. Slide the hearth firebrick into the grate clip. (Fig. 12)
The grate will be used as a handle to set the hearth
firebrick in place.
7. With the hearth firebrick securely in place in the
grate clip, carefully lift the hearth firebrick into the
fireplace, set the rear of the firebrick down, then slide
back to meet the rear firebrick. Gently set the front of
the firebrick in place. Replace screens and screen rod
smoke baffle assembly.

Since you have already preplanned the chimney run,
you should know exactly how the installation is to be
accomplished — how much pipe is required, the
number of elbows, if any, and type of termination to be
used.

NOTE: SHR Series Fireplaces must use CFM Corpora-
tion model 11CF, 11 inch, 2 wall chimney systems. The
installation procedure described in this manual applies
only to the 11CF system, chimney components may
not be mixed.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace in
final position and measure out from the wall 11¹⁄₈". Mark
a spot on the ceiling directly above the fireplace. Draw
a line parallel to the back wall through this mark. (Fig.
13)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 13)
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 6 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 straight up chim-
ney center point on ceiling.
Ceiling Chimney Hole/
Possible Obstructions
The size of the hole in 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, reposition chimney and/or
fireplace to avoid obstructions.
Cutting the Hole
Cover fireplace collar opening and cut proper sized
chimney hole in chimney. (Fig. 14 & 15)
Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure 15.
It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.

bers:
