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 Corporation components or the warranty
will be voided and a fire hazard may be created.
CFM Corporation warranty will be voided by and CFM
Corporation disclaims any responsibility for the following
actions:
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 manufacturer 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.
• Installation of any damaged fireplace or chim-
ney component;
• Modification of fireplace, chimney assembly or
any component parts thereof; (except for chase
flashings as detailed in Chimney Top installation
instructions).

• Installation other than as instructed by CFM
Corporation; or
• Installation and/or use of any component part
not manufactured or approved by CFM Corporation in combination or assembly with a Majestic Fireplaces fireplace system, notwithstanding 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.
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 vertical 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.
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 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 highest point where it passes through the roof.
WF288
Fig. 7 Installed lengths of chimney sections.
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 necessary 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.

SR/SC Series "A" Woodburning Fireplace
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 previously 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.
Installation
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 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)
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 FIREPLACE IN
AN INSULATED ENCLOSURE, BE SURE ALL REQUIRED AIR SPACES ARE MAINTAINED. (Page
14, Fig. 20)

SR/SC Series "A" Woodburning Fireplace
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 electrical wire through listed cable clamp leaving approximately 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 receptacle 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 installation instructions for field installation.

Chimney Setup
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.
CAUTION: REPORT TO YOUR DEALERS ANY
PARTS DAMAGED IN SHIPMENT, SPECIFICALLY
CHECK THE END CONNECTION OF CHIMNEY SECTIONS 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 chimney 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.
Chimney Centerline
Actual Centerpoint
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. Measure 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 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. 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.

the outside diameter of the chimney and the edges of
the framed ceiling hole.
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), allowing the remainder to extend in front of firebox. Overlap strips at least 1/2" (13mm) to provide a positive joint.
(Flat safety strips are packed with fireplace.) (Fig. 14)
Metal Safety
Strips
(1, 2 or 3 pieces)
NOTE: Safety strips are not required over noncombustible floors where all supports at the base of the
fireplace are noncombustible.
Four (4) nailing flanges are incorporated on each corner of the surround. Bend the nailing flanges out, level
the box, then secure it firmly in place by nailing the
flanges to the framing members as shown in Figure

Installing Outside Air Kit
An outside air kit is installed in all SR/SC 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 MUST be installed BE-FORE the fireplace is enclosed. Refer to the AK-MST
instructions for field installation.

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 metals strips
provided with the fireplace.
7412948
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 16. 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 snaplock. Middle pipes simply slide into position. Be sure
to always attach straps on upper elbow to a structural
framing member. (Fig. 17)
11
SR/SC Series "A" Woodburning Fireplace
UP
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.
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 13 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
Figure 18 shows different installation procedures 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. Framing
dimensions for the chimney hole should measure
14¹⁄₂" x 14¹⁄₂" (368 x
368mm). An attic shield
MUST be installed on top
of attic joists (above the
floor level). (Fig. 19)

If chimney supports are required, they are installed
the same as elbows. Nail chimney support straps to
adjacent structural framing, as shown on, Page 8, Fig.
9. 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.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. Refer to firestop
illustration on Page 12, Figure 18.
Penetrating the Roof
Run pipe to roofline. Since the 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 provided with the termination cap.
Locate Chimney Centerpoint On Roof
Use same procedure detailed in locating centerpoint of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
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 sec-
tions (all pipes) should extend.
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 a 1¹⁄₂ (38mm) air space between outermost portion of chimney sections and any adjacent
combustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,
flooring, combustible insulation and roof structures.)

Installing Chimney In a Chase
Refer to Page 5, Figure 5 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and construction 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
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. 20)
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 for
radiant models and 12" (305mm) from top of grille
opening for circulating models. Do not install a
mantel face plate less than 6" (159mm) from top
of fireplace opening for radiant models and 6"
(159mm) from top of grille opening for circulating
models. (Fig. 22) If a combustible material is used be-
low a flat mantel shelf, consult your local building codes
for minimum clearance from top of fireplace opening to
bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decorative facing material meets fireplace surround must
be completely sealed with a noncombustible material.
(Figs. 21 and 22)
NOTE: No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).
Often a decorative surround or vertical portion of the
mantel is desired. If this is constructed of any combustible material it must be within the safe zone indicated in
Figure 23.

Hearth Installation
A hearth extension is required to protect a combustible
floor in front of the fireplace. Refer to Figure 23 for minimum dimensions and mounting detail.
NOTE: Hearth Extension must not cover the air
inlet opening of a fireplace.
The hearth extension described in Figure 23 must be a
durable noncombustible material with a minimum (total)
Rt value of 1.09; refer to Figure 24 for examples. The
overall height (above a combustible floor), depth and
width must be as indicated, with the extension centered
to the fireplace opening.
The top of insulation 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. 23 and 25)

WARNING: HEARTH EXTENSION MUST BE INSTALLED IN ACCORDANCE WITH FIGURE 23 AND
MUST NOT COVER THE BOTTOM FRONT OPENING
OF THE CIRCULATING MODEL.
Alternate noncombustible materials may be used
providing the (total) thermal resistance (Rt value) of the
alternate 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
greater to maintain an equivalent (total) thermal resis-
tance (Rt).

Installing Line for Gas Logs
CFM Corporation fireplaces are designed to accept a
1/2" (13mm) gas line for installation of an approved gas
appliance. (CFM Corporation manufactures a wide variety of gas logs for use in CFM Corporation fireplaces.)
Be sure to have the appliance installed in accordance
with building codes.
Gas connection may enter from either left or right side
of the fireplace.
Locate appropriate gas line in the outer casing of fireplace and remove insulation from gas line tube. (Fig.
26)
From inside the fireplace, locate the knockout on the
firebrick -- be sure you are on the appropriate or "gas
line" side of the fireplace. Using a flat bladed screwdriver or small chisel and hammer, carefully tap around
the knockout until it loosens and falls out.
Install 1/2" (13mm) certified gas pipe through opening.
After gas pipe installation is complete, use insulation
that was removed from gas line tube to repack space
around the pipe. Material should be inserted from
outside of the fireplace and packed tightly to totally seal
between the pipe and tube.
NOTE: Gas pipe should not come in contact with
any wood structures until it has reached a point at
least one (1) inch away from fireplace side.
NOTE: When installing an ANSI Z21.11.2 ventless ap-
pliance the finishing material used for the mantel must
be rated at 250°F or greater.
BTU input of a gas appliance installed in fireplace
should be rated less than 100,000 BTU/Hr.
Gas pipe installation is intended for connection to a
decorative gas appliance only when (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
requirements for Gas-Fired Log Lighters for Woodburning Fireplaces (Draft No. 4, August 1993).
Decorative gas appliance should be installed in accordance with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54 (latest edition).
