INSTALLATION PRECAUTIONS
This MAJESTIC Fireplace and its components have been
tested and will operate safely when installed in accord-
ance with this Installation Manual. Read ait instructions
before starting installation, then follow these instructions
carefully during instalation to maximize fireplace benefit
and safety.
Report to your dealer any parts damaged in shipment,
Specifically, check for loose insulation in the fireplace
and damper operation.
Since this fireplace and chimney assembly is a highly
engineered system, unless you use Majestic or Majco
Building Specialties (MBS) components which have been
designed for the system, you may create a possible fire
hazard.
The MAJESTIC warranty will be voided by, and
MAJESTIC disclaims any responsibility for, the
following actions:
* installation of any damaged fireplace or chimney
component;
e Modification of the fireplace, chimney assembly or
any of the component parts thereof; (except for
chase flashings as detailed in MBS Chimney Top
installation instructions.)
e Installation other than as instructed by MAJESTIC;
or
Installation and/or use of any component part or
accessory not manufactured or approved by
MAJESTIC in combination or assembly with a
MAJESTIC fireplace system, notwithstanding any
independent testing faboratory or other third party
approval of such component part or accessory.
Any such action may create a possible fire hazard.
Consult your local building codes.
This fireplace and chimney system must be vented
out-of-doors.
Do not obstruct or modify air inlet/outlet grilles in any
manner.
Do not install combustible materials onto the black
fireplace surround.
Burn solid wood fuel only.
Do not instal! a fireplace insert or other products not
specified for use with this fireplace.
THE MST AND MSF SERIES FIREPLACES ARE NOT
APPROVED FOR INSTALLATION IN MOBILE HOMES.
Prior to first firing, read Owner's Manual for operating
instructions.
INSTALLATION INSTRUCTIONS
A. Installing the Fireplace
(3 A-1. CHECK HOW ACCESSORIES ARE
INSTALLED |
Determine where selected accessories fit into this
fireplace installation procedure by checking the
instaflation instructions provided with each accessory.
See Accessory Parts, page 15.
NOTE: The outside air system (MST and MSF) and
electrical connection (MST) for the fireplace cannot
be installed after the fireplace is completely installed.
С) А-2. DETERMINE FIREPLACE LOCATION
The fireplace can be mounted on any of the following
surfaces: 1) A flat, hard, combustible surface
2) A raised wooden platform
The fireplace must maintain a Y inch air space at sides
to combustible materials and insulation.
Nearby combustible floors and walls must be protected
as detailed in Section H.
Refer to Air Space Data and Dimensions on pages 13 and
14 to be sure that the location which you have selected
for your fireplace provides for clearance and framing
restrictions.
At this point you should have decided what components
to include in your installation, where the fireplace is to be
located, and how the chimney will be routed to the roof
(straight-up, offset, or chase"). If this has not been done,
stop and-consult your Majestic Dealer for assistance with
this planning.

[1 A-3. INSTALL METAL SAFETY STRIPS UNDER
FIREPLACE
See Step G, Insulating Fireplace Enclosure for Cold -
Climates, before completing Step A-3.
Thoroughly clean intended fireplace location area. Move
fireplace to the location where it is going to be installed.
Lift fireplace front slightly to slide metal safety strip(s)
under front bottom edge about 1% inches, allowing the
remainder to extend out in front of the fireplace. Overlap
the strips at least ¥2 inch to provide a positive joint. (See
Fig. 3.) (Flat safety strips are packed with fireplace.)
In the event the fireplace is elevated above the floor, a
“Z'" shaped metal safety strip should 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 1% inches wide — equal in length to the meta!
strips provided with each fireplace.
When positioning the fireplace on all mounting surfaces
(see Step A-2), the metal safety strips must be installed
as described above to provide protection to combustibles
{burnable} surfaces in front of the fireplace.
NOTE: Safety strip is not required over non-combustible
floors where all supports at the base of the fireplace are
non-combustible.

NOTE: The MST and MSF Series fireplaces may use
MBS Model CF8, 2 wall chimney components or MBS
Model S, 3 wall chimney system. The installation
procedure described in Section B (Installing the
Chimney), applies to both systems. Either system may be
used, but 2 wall and 3 wall components may not be
mixed. For clarification, refer to the Accessory Section of
this manual beginning on page 15. Components from
Section 1 are common to all installations. Chimney com-
ponents may be selected from Section 2 or Section 3,
but may not be mixed.
[} ВА. LOCATE CENTERPOINT OF CHIMNEY —
STRAIGHT UP INSTALLATION
The fireplace is ideally suited as a room divider, and for
optimal heat performance should be centrally located.
You should consider ceiling and roof rafters that may
require cutting, plumbing and wiring that may have to be
moved when deciding where to locate the firebox. Then,
using a plumb bob positioned directly over the center
point of the fireplace flue collar, mark the ceiling to
establish the chimney center point. (See Fig. 5.)
{1 B-2. LOCATE CENTERPOINT OF CHIMNEY
OFFSET INSTALLATION
in order to clear an obstruction, it may be necessary to
offset the chimney from the vertical plane. This is done
by using MBS 30° CHIMNEY ELBOWS: Model CF830A
and 830A (30°). Each offset requires a pair of elbows.
Use Table 1 and Fig. 6 to determine the offset that may
be obtained using the various elbows.

Fig. 6. Typical offset installations.
The following safety rules appiy to offset installations.
(The letters below match the letters in Fig. 6.)
A. Height of the chimney measured from the hearth to
the chimney exit at top:
MST36/MSF36
Maximum: 45 Feet
Minimum:
Without Elbows 15 Ft, 8 In.
With 2 Elbows 15 Ft. 8 in.
With 4 Elbows 24 Ft. 6 in.
8. Do not use more than four elbows per chimney.
* Attach the straps of the top elbows to a structural
framing member.
“* The first elbow of any pair does not have straps.
The chimney cannot be more than 30° from the
vertical plane. |
The maximum length of the angled run of the total
chimney system is 20 feet.
A chimney support (Mode! TCS8A) is required every 6
feet of angied run of chimney. A chimney support is
required at 30 feet of chimney height above the
hearth also.
Determine the offset distance of your chimney arrange-
ment 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 (1).
Locate on the ceiling the centerpoint of the chimney, as
though a straight up chimney arrangement is to be used,
by following the procedure outlined in Step 8-1, Then
measure your offset dimension from the actual chimney
centerpoint on the ceiling. (Fig. 7.) {See below.)

1 B-3. MARK AREA OF CEILING CHIMNEY HOLE
The size of the ceiling chimney hole will vary with the
angle at which the chimney passes through the ceiling.
Refer to Table 2.
Drive a nail up through the ceiling at the marked chimney
centerpoint. Go to the floor above and check where the
hole will be cut, relative to the ceiling joists and any
obstructions such as wiring or plumbing runs. If
necessary, re-position the chimney and/or the fireplace to
hatter accommodate these joists and/or obstructions.
D B-4. CUT CEILING CHIMNEY HOLE
After covering the opening of the fireplace collar, cut the
chimney hole through the ceifing. Recheck the hole to be
sure that it measures the hole size selected from Table 2.
(] B-5. FRAME CEILING CHIMNEY HOLE
Frame the ceiling chimney hole as shown in Fig. 8. itis
good practice to use framing lumber that is the same size
as the ceiling joists. (This is a requirement at the attic
level.)
The inside dimension of the frame must be the same as
the hole size selected from Table 2 in order to provide the
required 2 inch air space between the outside diameter of
the chimney and the edges of the framed ceiling hole.

[] 8-6. INSTALL FIRESTOP SPACER
Firestop spacers are required for safety. The hole sizes
listed in Table 2 for angled firestop spacers provide the
minimum required air space to the chimney pipe for
ceiling thicknesses up to 8 inches. When the combined
thickness of the ceiting material, ceiling joists and fioor-
ing material exceeds 8 inches, adjustments must be
made in the framing to assure that the minimum air
spaces to the chimney are maintained.
If the area above the ceiling is net an attic, position the
firestop spacer with the flange on the ceiling side and the
dished or 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 dished or angled portion extending down into the
hole. (See Figs. 9 & 10.)
Nail each corner of the firestop spacer to the framing
members of the ceiling hole. NOTE: A firestop spacer is
not required at the roof.

1] B-7. ATTACH CHIMNEY SECT IONS
Attach the first straight chimney section to the fireplace
collar, or if offset installation, attach elbow to the fireplace
collar. (Refer to Step 5-8.) Mount the flue pipe first, using
the built-in snap-lock fasteners. {See Fig. 11.) Then mount
the additional pipe(s). Position each pipe section so the
direction arrow is pointing UP.
Make sure each pipe is firmly snapped and locked
together as it is mounted.
Continue installing chimney sections until ONE SECTION
(all pipes) extends up through the ceiling hole. To extend
through the ceiling, it may be necessary 10 assemble all
pipes, push them up through the ceiling hole and then
slide them down one at a time to connect them.
O B-8. ATTACH FIRST ELBOW — OFFSET
INSTALLATION
If the first elbow is not to be attached to the fireplace,
install chimney sections as required.
Attach first elbow where required. Note that oniy the outer
pipe snap-locks.

1 B-9. DETERMINE HOW MANY CHIMNEY
SUPPORTS ARE NEEDED
The chimney system is supported by the fireplace for
chimney heights less than 30 feet of vertical height above
the hearth. Chimney supports are required if the chimney
height exceeds 30 feet. Locate chimney supports at
ceiling holes or other structural framing at 30 foot
heights. Spacing between chimney supports must not
exceed 30 feet. Use MBS Chimney Support Model
TCS8A. (NOTE: The TCS8A can not be mounted
directly to the fireplace.) Support provided by elbow
straps fulfills the support requirement only if they are
spaced as required above.
Angled chimney runs require support every 6 feet in
addition to the elbow straps. MBS Chimney Supports are
used for this function.
Refer to Step B-2 to determine how many chimney
supports are needed and where they will be placed in the
chimney run.
NOTE: A chimney support is 2% inches long when
installed. This dimension must be considered when
determining how many straight chimney sections are
needed to provide the desired offset.
(7 B-10. INSTALL CHIMNEY SUPPORTS
Chimney supports are attached to chimney sections the
same way elbows are attached. Refer to Step B-8. Nail
the chimney support straps to adjacent structural
framing, as shown in Fig. 12. Bend the straps as
necessary and make sure they are tight so they will be
able to support the weight of the chimney.
O 8-11. LOCATE CENTERPOINT OF NEXT
CEILING HOLE
NOTE: If there is no other ceiling, you have completed
Section B. Turn now to Section C, Penetrating the Roof.
In a manner similar to that used in Steps B-1 and B-2,
mark the centerpoint of the next ceiling hole.
(1 B-12. PREPARE SECOND CEILING HOLE
Repeat Steps B-3. Mark area of ceiling chimney hole;
8-4, Cut ceiling chimney hole; B-5, Frame ceiling
chimney hole; and B-6, install firestop spacer.
[7] B-i3. CONTINUE INSTALLING CHIMNEY
SECTIONS
Continue installing chimney sections and chimney
supports (as required), until the chimney passes through
the second ceiling hole.
NOTE: Repeat Steps B-11 through B-13 as many times as
necessary to pass through all the ceilings in the building
and bring the chimney just short of the roof.
C. Penetrating the Roof
The chimney system must be vented out-of-doors and
must be terminated in an approved MBS top termination.
NOTE: if you are using a chase, go to Section D.
[7 C-1. LOCATE CHIMNEY CENTERPOINT
AT ROOF
Use the same procedure detailed in Steps B-t and B-2.
Drive a nail up through the roof at the marked center-
point. This will mark the centerpoint on the outside of
the roof.
[1 C-2. CUT AND FRAME ROOF HOLE
The size of the roof hole varies with the type of chimney
top that will be installed. Refer to the installation
instructions provided with your MBS chimney top
termination to find the correct size of roof hole for this
installation. There must be at feast 2 inch air space
between the outermost portion of the chimney sections
and any adjacent combustible (burnabte) surfaces.
WARNING: DO NOT PACK REQUIRED AIR SPACES
WITH INSULATION OR OTHER MATERIALS.
(Combustible surfaces include such things as ceiling
members, joists, flooring, combustible insulation and roof
structures.)
Mark the outline of the roof hole around the centerpoint
пай, Note: The 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.
Cut and frame the hole. tt is good practice to use framing
tumber that is the same size as the rafters. install frame
securely. Chimney top and flashing anchored to frame
must withstand heavy winds.
[0 C-3. DETERMINE MINIMUM CHIMNEY HEIGHT
ABOVE ROOF
Major U.S. building codes specify minimum chimney
height above the roof top. These specifications are
summarized in the Ten Foot Rule. (See Fig. 13.) The key
points of this rule are:
1. Ifthe horizontal distance from the center of the
chimney to the peak of the roof is 10 feet or less, the
top of the chimney must be at least 2 feet above the
peak of the roof, but never less than 3 feet in height
above the highest point where it passes through the
roof,
o f a horizontal distance from the center of the chimney
to the peak of the roof is more than 10 feet, a
chimney height reference point is established that 1s
on the surface of the roof a distance of 10 feet from
the center of the chimney in a horizontal plane. (See
Fig. 13.) The top of the chimney must be at least 2
feet above this reference point, but never less than 3
feet in height above the highest point where it passes
through the roof.
These chimney heights are necessary in the interest of
safety and do not assure a smoke-free operation.
[] C-4. INSTALL REMAINDER OF CHIMNEY
SECTIONS
Continue installing chimney sections up through the root
hole. Check your chimney top installation instructions
for data on how high above the top of roof the CHIMNEY
SECTIONS (all pipes) should go.

D. Installing Chimney in a Chase
A chase is a vertical box-like structure built to enclose the
fireplace and/or its chimney.
CAUTION: Treatment of firestop spacers and construction
of the chase may vary with the type of building. These
instructions are not substitutes for the requirements of
local building codes. Therefore, your local building codes
must be checked to determine the requirements for these
steps.
NOTE: Other material may be required in addition to
MBS Firestop Spacers.
Refer to Framing and Finishing on page 10. Upon comple-
tion of building your chase frame, instal! the chimney
system. Follow the instructions for Installing the Chimney
starting on page 4. Then proceed to Step D-1.

E. install the Electrical Connection
(MST Only)
EC] E-1. ELECTRICAL CONNECTION
Fan Junction Box is directly connected to the fan motor and
assembly. See instructions shipped with the FK-MST fan
kit.
CAUTION: ALL WIRING SHOULD BE DONE BY A
QUALIFIED ELECTRICIAN AND SHALL BE IN
COMPLIANCE WITH ALL. LOCAL, CITY AND STATE
BUILDING CODES.
(] E-2., ELECTRICAL POWER
The fans require 120 VAC, 60 Hz power available at the
left side of the fireplace. The power should be available to
the fireplace through a single Listed 15 AMP 125 V wall
switch. (Switch not provided.)
Li E-3. INSTALLATION OF FIELD WIRING
A junction box is provided with the fan.
Next, route the field supplied wiring from the switch box
to the junction box in accordance with local electrical
codes. Be sure wiring does not contact outer fireplace
surfaces and support wiring in a manner that will assure
clearance from the fireplace components.
insert 120 Y, 60 Hz power lines through either knockout
in the back or side of the junction box. The ground wire
from the power should be attached to the ground stud in
the top of the junction box with one of the supplied
retaining nuts.
Using wire nuts, connect the ends of the white and black
power leads to the fireplace leads (See Wiring Diagram,
supplied with fan kit), making sure the wire nuts are tight
to the leads. All black leads should be connected together
and all white leads should be connected together,
CL] E-4. SERVICING OF FANS
it is recommended to service fans once a year. Servicing
involves cleaning of the blower mesh vent and oiling the
bearing. Removal of the fan should not be necessary.
Vacuuming dust and int from blower housing will
increase fan efficiency. We recommend using a light
weight oil once a year on both front and rear bearings.
installation instructions accompanying fan kit will show
location of oil ports.
if the fan needs to be removed, turn off power to fan, and
disconnect the wires. Remove top screw holding the fan
up. With the screw removed, the fan can be lifted and
removed from fireplace side.
L] E-5. ADDING FAN ON INSTALLED UNITS
Installation on some units may not be advisable. You will
have to cut an access hole of 12" x 12” located near the
unit in order to allow access to the fan for better servic-
ing. The hole must be cut on the opposite side of the
outside air control (left side). The bottom of the 12" x 12"
hole must start 2-inches up from the bottom of the
fireplace. Refer to fan installation instructions for proper
location.
F. Installing Optional Outside Air Kit
and Fan Kit
Later addition of outside air and fans (without preinstalled
Wiring Kit) will require significant reconstruction. These
accessories should be installed at the time of original
installation of the fireplace.
Ll F-1. INSTALL QUTSIDE AIR KIT
Install outside air kit if desired or required by local code.
Refer to AK-MST installation instructions supplied with
the appropriate kit.
C) F-2. INSTALL FAN KIT (MST Only)

. Cold Climates
When installing the fireplace, it is always good building
practice to insulate as you would an outside wall of your
home.
In cold climates, insulation of the enclosure around the
fireplace is critical to avoid future problems with cold air.
The following steps are suggested to minimize potential
cold air problems.
[1] G-1. INSULATE BASE OF FIREPLACE
Insulate the base of the fireplace with a non-combustible
insulation rated for a minimum of 300*F, This step is
particularly important for outside wall installations over
concrete slab floor construction. If a platform is used to
raise the fireplace, the insulation should be placed on top
of the platform before the fireplace is set (See Fig. 14.)

Li] G-2. INSPECT JOINTS
tnspect joints of the fireplace as well as the points of
sealing between the fireplace and the finishing materials.
Any cracks should be sealed with non-combustible
caulking or insulation. See Fig. 15 for details of sealing
spaces between the fireplace and finishing materials,

(7) G-3. INSULATION OF ENCLOSURE
When a fireplace is installed in a chase, the enclosure
should be insulated like any other wall of the home.
Insutation should be installed on the inside wall. Ina
chase, it is also a good idea to install a firestop at the first
ceiling level above the fireplace and close the chase with
sheeting material. insulation may then be installed above
the sheeting material to assure the space around the
fireplace is totally protected.
CAUTION: WHILE INSTALLING A FIREPLACE IN AN
INSULATED ENCLOSURE, BE SURE ALL MARKED AIR
SPACES ARE MAINTAINED.
H. Framing and Finishing
1 H-1. DETERMINE WHEN TO INSTALL FRAMING
Fireplace framing can be buiit before or after the
fireplace is set in place. Fig. 16 shows the minimum
framing dimensions.
[1 H-2. BUILD FRAMING
The fireplace framing should be constructed of 2x 4
umber or heavier. Refer to Dimensions on page 14 for
basic fireplace dimension that will affect the framing
dimensions.
The header may rest on the fireplace standoffs.
Framing should be positioned to accommodate wall
covering and fireptace facing material. (See Figs. 22 and
23 tor typical arrangements.) Standoff nailing tabs pro-
vided on the top of the fireplace can be used to position
the fireplace for a 54" finished wal! covering, as well as
anchor the fireplace. Nail through the tabs (4) into the
horizontal framing members. (See Figs. 4 and 16.)

CAUTION: All joints between the finished wali and the
fireplace surround (top and sides) must be sealed
with non-combustible material. Only non-combustible
material may be applied as facing to the tireplace
surround.
CJ 4-3, FINISH WALL
Finish the wall with material of your choice, Do not
install a combustible mantel less than 12” above the
outlet grille on MST36 or 12 inches above fireplace
opening on MSF36. if a combustible material is used
below a fiat mantel shelf, consult your toca! building
codes for the minimum clearance from the top of the
fireplace opening to the bottom of the material.
~All joints (top, bottom and sides), where the wall or
decorative facing material meets the fireplace surround
must be completely sealed with a non-combustible
material. (See Figs. 17, 18 and 19)
Only non-combustible material may be applied as facing
to the black fireplace surround.
When finishing the fireplace, never obstruct or modify
the air inlet/outlet grilles in any manner.

[] H-4. ADD PROTECTION TO SIDE WALLS
Adjacent combustible side walls that are within 14" of
the MST fireplace openings must be protected with MBS
Wall Shield Model SP40 or a built up wall shieid
described in Fig. 20. (See Figs. 20 and 2.)
The built-up wall shield design described in Fig. 20 is an
alternate method for adding protection to side walls and
can be used in place of the SP40 with the same wall
clearances specified for the SP40.

[7 H-5. INSTALL HEARTH EXTENSION.
A hearth extension is required to protect combustible
floor construction around the fireplace, and it must be a
hearth extension constructed of a rigid insulation or a
durable non-combustible material with equal or greater
(total) insulating value than Ar = 1.16, sized as shown in
Fig. 21. (See Table 4 for examples.) The overall height
(above combustible floor), depth and width must be as
indicated, with it centered to the fireplace opening.

TABLE 4. Common materials and their factors.
The top of the rigid insulation must be covered with a
non-combustible decorative covering or a piece of .018"
minimum sheet metal, to protect the hearth extension
materials. {See Fig. 21.)
Secure the hearth extension to the floor to prevent
shifting, using trim molding or other similar means at the
three (3) outer edges. Seal the crack between the
fireplace hearth and the hearth extension with a non-
combustible material. (See Figs. 22 and 23.)
WARNING: HEARTH EXTENSION MUST BE
INSTALLED IN ACCORDANCE WITH FIGS. 21, 22
AND 23.
Alternate, non-combustible materials may be used,
providing the (total) thermal resistance (Rr value) of the
alternate material employed is greater than or equal to an
R = 1.16. The thermal resistance (R) or the thermal
conductivity (K), may be obtained from the manufacturer
of the material. The factors are related by the formula
К = 1/R.
T = given thickness
В = thermal resistance for a given thickness (T)
K = thermal conductivity
Non-combustible materials with a lower R value per inch
may be used, provided the thickness of the material is
sufficiently greater to maintain an equivalent (total)
thermal resistance (Rr = 1.16).

Next, insert a % inch gas pipe through the gas line tube
from the outside of the fireplace and forcibly punch out
the ceramic or metal knockout on inside of the fireplace.
Now, install the % inch gas pipe through the opening.
After the gas pipe installation is complete, use the insula-
tion that was removed from the gas line tube to repack
the space around the pipe. This should be inserted from
the outside of the fireplace and packed tightly to totally
seal between the pipe and the tube.
NOTE: The gas pipe should not come in contact with
any wood structures until it has reached a point at
least one (1) inch away from the fireplace side. (See
Fig. 24 for installation clarification.)
NOTE: Local codes may require removal of the flue
damper when installing any type of gas appliance in a
fireptace. For instructions on damper removal, contact
