Safety Information
Description
The ODSHR Series (Super Hearth) fireplace is a clean-
faced, solid fuel, woodburning fireplace.
Precautions
CFM Corporation fireplaces and component 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 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:
• Installation of any damaged fireplace or chimney
component;
• Modification of fireplace, chimney assembly or any
component parts thereof; (except for chase flashings
as detailed in the Chimney Top installation instruc-
tions).
• Installation other than as instructed by CFM Corpora-
tion; or
• Installation and/or use of any component part not
manufactured or approved by CFM Corporation in
combination or assembly with a CFM Corporation
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.
WARNING: To avoid the risk of damaging fireplace
materials and increasing the risk of spreading a fire,
do not use the fireplace to cook or warm food.
Do not obstruct or modify air inlets/outlets in any
manner.
Do not install combustible materials on any of the
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.
These fireplaces are not approved for installation in
mobile homes.
This fireplace is not designed to be water tight.
Therefore, when installing this unit against an exte-
rior wall, the wall must be finished before setting unit
in place.
NOTE: This unit is intended for outdoor use in the United States using CF11 or SK chimney systems. The unit
may be installed indoors, in the U.S. only, using CF11 chimney system only. This unit is intended for outdoor
use in Canada using the SK chimney system only.
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.
Cleaning
There are three methods of cleaning the polished stain-
less steel of your outdoor fireplace;
1. Warm, soapy water - to loosen any dirt film
2. Glass cleaner with ammonia
3. Stainless steel cleaner available at hardware stores
Regardless of which method is used, remember that any-
thing with too much abrasive may dull the finish.
Proposition 65 Warning: Fuels used in gas, woodburning
or oil fired appliances, and the products of combustion of
such fuels, contain chemicals known to the State of Cali-
fornia to cause cancer, birth defects and other reproductive
harm.

Illustration Key
The following safety rules apply to offset
installations (letters correspond with illustra-
tion above):
A. Height of the chimney is measured from
the hearth to the chimney exit.
ODSHR42
Maximum: 90' (27.4 m)
Minimum:
Without Elbows 14'6" (4.4 m)
With 2 Elbows* 15'6" (4.7 m)
With 4 Elbows* 21'0" (6.4 m)
B. Do not use more than 4 elbows per
chimney.
Attach the straps of the return (top) elbow
to a structural framing member.
The offset (first) elbow of any pair does not
have straps.
C. The chimney cannot be more than 30˚
FP269
from the vertical plane in any installa-
tion.
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
2 and 3.

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 termina-
tion 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' (3 m) 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 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' (610 mm) above the
reference point, but never less than 3' (914 mm)
in height above the highest point where it passes
through the roof.
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" (19 mm) from a
combustible back wall and 3/4" (19 mm) from a com-
bustible 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. 7) 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' (6 m).
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' (1.8 m above a roof line.

Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30' (9 m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30' (9 m) 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' (9 m). 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" (64mm) 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. 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. 4)
If you need help in determining fireplace location or how
the chimney system should be run, contact your CFM
Corporation 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 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. 4)
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
REQUIRED AIR SPACES ARE MAINTAINED. (Page
14, Fig. 20)

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
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.
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 or 3 for
basic fireplace specifications.
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
accomplished — how much pipe is required, the num-
ber 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.
NOTE: ODSHR Series Fireplaces must use CFM Cor-
poration 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"
(283mm). 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 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.

Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure
13. It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.
