Safety Information

NOTE: These units are intended for outdoor use in the United States and Canada using the 'SK' chimney sys­tem. These units may also be used outdoors in the United States and Canada using the 'S' chimney system
with an adapter. These units may also be used indoors.

Description

The ODSR Series "A" fireplaces are clean-faced, solid
fuel, woodburning fireplaces.

This fireplace is not designed to be water tight.
Therefore, when installing this unit against an exte­rior wall, the wall must be finished before setting unit
in place.

Precautions

Majestic 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 MHSC components or the warranty will be
voided and a fire hazard may be created.

MHSC warranty will be voided by and MHSC 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 MHSC Chimney Top installation
instructions).

• Installation other than as instructed by MHSC; or

• Installation and/or use of any component part not

manufactured or approved by MHSC in combination
or assembly with a MHSC 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.

Moisture Resistance

This outdoor fireplace will shed moderate amounts of
water, but is not waterproof. Water and condensing water
vapor may enter the chase under certain conditions.

The fireplace will not perform as an exterior wall. Mois­ture penetration must be considered for construction
that places the fireplace in structure walls or on moisture
sensitive surfaces.

When installed on exterior walls: MHSC recommends
the fireplace chase be constructed outside the structure's
weather envelope. Where the platform meets the wall,
use a flashing detail similar to that required for attached
decks. Chase platforms, including hearths should slope
away from the structure at 1/4 in per foot. The fireplace
can be shimmed level.

When installed on surfaces where water may collect or
cause damage: MHSC recommends a slope of 1/8 in
to 1/4 in per foot towards the drain port suggested. The
fireplace can be shimmed level.

Hearths should slope away from the front of the fireplace
and chase at 1/8 in to 1/4 in per foot. Metal safety strips
must be on top of any combustible hearth materials used
for moisture management.

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 stain­less 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 any­thing with too much abrasive may dull the finish.

Without Elbows 12' 6" 12' 6"
With 2 Elbows* 14' 6" 14' 6"
With 4 Elbows* 21' 0" 21' 0"

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.

ODSR36A ODSR42A

* In Canada, two (2) SK845 are allowed.

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.

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.

Moisture Resistance

This outdoor fireplace will shed moderate amounts of
water, but is not waterproof. Water and condensing wa­ter vapor may enter the chase under certain conditions.

The fireplace will not perform as an exterior wall. Mois
ture penetration must be considered for construction
that places the fireplace in structure walls or on mois­ture sensitive surfaces.

When installed on exterior walls: MHSC recommends
the fireplace chase be constructed outside the struc­ture's weather envelope. Where the platform meets
the wall, use a flashing detail similar to that required
for attached decks. Chase platforms, including hearths
should slope away from the structure at 1/4 in per foot.
The fireplace can be shimmed level.

When installed on surfaces where water may collect or
cause damage: MHSC recommends a slope of 1/8 in
to 1/4 in per foot towards the drain port suggested. The
fireplace can be shimmed level.

Hearths should slope away from the front of the fire­place and chase at 1/8 in to 1/4 in per foot. Metal safety
strips must be on top of any combustible hearth materi­als used for moisture management.

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" (13 mm) from a
combustible back wall and 1/2" (13 mm) from a com­bustible side wall or support. (Page 21, Fig. 21)

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.

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

8

vertical plane.

-

WF288

Fig. 8 Installed lengths of chimney sections.

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 extend­ing more than 6' (1.8 m) above a roof line.

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. 9)

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 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' (614 mm) in height above the high­est point where it passes through the roof.
