Safety Information
PLEASE READ THIS MANUAL BEFORE INSTALLING AND USING FIREPLACE.
IMPORTANT:
Read all instructions and warnings carefully before starting installation. Failure to
follow these instructions may result in a possible fire hazard and will void the warranty.
Description
The SR/SC Series "A" fireplaces are solid fuel, woodburning premium fireplaces. The SR36A/42A are radiant
clean-face models and the SC36A/42A are circulating
models with removable grilles (louvres). Both models are
fully insulated fireplaces.
Precautions
MHSC 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:
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.
-
• Installation by any other than a qualified install-
er, preferably NFI or WETT (Canada) certified.
• 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 MHSC;
or
• Installation and/or use of any component part
not manufactured or approved by MHSC 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.
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.

D. The maximum length of the angled run
of the total chimney system is 20 feet. (G
plus H cannot exceed 20 feet.)

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

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 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 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.

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)
