• Installation and/or use of any component part
not manufactured or approved by CFM Corpo-
ration in combination or assembly with a Majes-
tic Fireplaces fireplace system, notwithstand-
ing any independent testing laboratory or other
third party approval 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
products not specified for use with this fireplace.
Proposition 65 Warning: Fuels used in gas, wood-
burning or oil fired appliances, and the products 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
WARNING: Check with your electronics manufac-
turer before installing a television or other electronic
device above this fireplace.
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 the
fire.
Gas Logs
If you plan to install a gas log, the gas line should be
installed before framing the fireplace. The gas line must
be installed by a certified gas line installer.

not have straps.
IWF269
C. The chimney cannot be more than 30˚
(45˚ in Canada) 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 SKCS8)
is required every 6 feet of angled run of
chimney. Chimney supports are required
for every 30 feet and 60 feet (SK8 pipe)
or 20 feet and 40 feet (3-wall pipe) of ver-
tical chimney height above the hearth.
Determine the offset distance of your
chimney 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 1/2" (13mm) from a com-
bustible back wall and 1/2" (13mm) from a combustible
side wall or support. (Page 14, Fig. 20)
Planning the Chimney Run
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 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' (614mm) in height above the high-
est point where it passes through the roof.
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.
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' (6m).
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' (1.8m) above a roof line.

Insulating Fireplace Enclosure for Cold
Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much
as possible.
Insulate base of fireplace with a noncombustible in-
sulation 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 in-
stalled 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. Insu-
lation may then be installed above sheeting material
to assure the space around the fireplace is totally
protected. (Fig. 5)
When installing the chimney, DO NOT caulk be-
tween outer pipe and firestop. It is vital that some
air be allowed to flow through this very thin gap.
CAUTION: WHEN INSTALLING A FIREPLACE IN
AN INSULATED ENCLOSURE, BE SURE ALL RE-
QUIRED AIR SPACES ARE MAINTAINED. (Page
14, Fig. 20)
Installation
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30' (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30' (9m) with SK8 chimneys or 20'
(6m) with 3-wall chimneys. Locate chimney supports
at ceiling holes or other structural framing at 30' (9m)
(SK8) or 20' (6m) (3-wall) heights. Spacing between
chimney supports must not exceed 30' (9m) (SK8) or
20' (6m) (3-wall). Use Chimney Support Model SKCS8.
(NOTE: The SKCS8 can not be mounted directly to
the fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as pre-
viously described. (A chimney support is 2¹⁄₂" (64mm)
long when installed.)
Angled chimney runs require a support every 6' (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 9)
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 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.

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, 2, 3 or 4 for
basic fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Installing Electrical Wire
(for Circulator Models)
If a circulating fireplace is to be installed, run the 120
VAC, 60 Hz wiring to the left side of installation. Wiring
must be completed before the fireplace is secured and
finish material applied.
Remove the cover plate and electrical knockout on the
lower left side of the fireplace and set aside. Follow the
instructions on Page 10 for proper wiring and installation
of the EB1.
If the fan kit is not being installed with the fireplace, it
is highly recommended that 120 VAC supply be made
available since someone may elect to install a blower at
a later date.
Option For Circulating Models Only —
EB1 (Receptacle) Hook-Up
• Wiring should be installed by a certified
electrician.
• Turn off circuit breaker before wiring models.
Once fireplace is secured, complete wiring the fan
kit. Remove knockout in the center of the back of
the EB1 and install listed cable clamps. Feed electri-
cal wire through listed cable clamp leaving approxi-
mately six (6) inches of wire exposed through the
EB1. Secure listed cable clamp to the wire.
Attach white wire from power source to one (1) wire
of receptacle and secure with nut. Attach black
wire from power source to the other wire of recep-
tacle and secure with nut. Be sure nuts are secured
tightly.
Secure EB1 assembly to inside of electrical box
coverplate using two screws. Attach cover to face of
the EB1 while being careful to position excess wire
completely within the EB1, then attach coverplate to
fireplace.
Install Fan Kit Assembly
Refer to optional Model FK12 fan kit assembly in-
stallation instructions for field installation.
Chimney Setup
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 DEALERS ANY
PARTS DAMAGED IN SHIPMENT, SPECIFICALLY
CHECK THE END CONNECTION OF CHIMNEY SEC-
TIONS AND ELBOWS.
NOTE: Fireplaces may use CFM Corporation model
SK8, or Model S (three wall) chimney systems. The
SR/SC Series "A" Fireplace will accept the SK8 chim-
ney system as is; but a TWABR adapter collar is
required when using the Model S (triple wall) chimney
system. The installation procedure described in this
manual applies only to the SK8 system. Either chimney
system may be used, but 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: 9¹⁄₄"
(235mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 11)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 11)
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 that 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. Mea-
sure your offset dimension from straight up chimney
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 cen-
ter 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. 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
12. It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.
