opeRation guidelines
When a AK4 combustion air assembly and a combustion air duct are attached to the connecting point on the left
of the replace, combustion air may enter the rebox through a dampered opening behind the left side panel.
This feature is designed for your benet to reduce the room air used for combustion and to prevent excessive
loss of heat from the room. When the replace is in use, this damper should be open. When the replace
is not in use, the damper should be closed to prevent cold air from entering the rebox. The combustion air
damper is open when the lever, located on the left side of the rebox near the top of the left rebrick, is up and
closed when the lever is down.
Outside air for combustion is optional unless required by federal, state or local building codes. See the section
of this manual providing the instructions for installation of the combustion air assembly. The design of the
replace allows the routing of the combustion air duct up, down, or horizontally to obtain the outside combustion
air. This permits exibility in planning your installation. See Figure 23 for typical installation methods. Review
the precautions and recommendations in this manual pertaining to outside combustion air installation.
Glass doors should be installed to receive the maximum benet from your replace. For large res, the
maximum heating benet from the replace will be obtained with the doors open due to the high amount of
radiant heat being emitted out of the front opening of the replace. With a small re, or before retiring in the
evenings, it is best to operate the replace with the doors closed to prevent excessive room air form being
drawn up the chimney. When the doors are open, the mesh screens should be closed to help keep burning
embers from popping out of the rebox.
The replace should also be equipped with a ue damper, which must be open when the replace is in use.
The ue damper control lever is located inside the replace. The counterweighted damper is operated by
simply pushing up to open or pulling down to close the damper. When the replace is not in use, the damper
should be closed to prevent cold air form entering the chimney as well as preventing warm air in the room
from escaping up the chimney.
NOTE: It is normal for a small amount of smoke to be released from the upper portion of the replace the rst
few times you use your new replace. This results from an oil residue on the metal. Open a door or window
to allow the smoke to escape.
The grate included with this replace helps to appropriately locate and contain the burning wood. Failure to
use this grate may cause overheating of parts of the replace and allow large pieces of burning wood to roll
forward out of the rebox. If the grate becomes warped or damaged, it must be replaced with grate number
050456 only.
WARNING: Fireplaces equipped with doors should be operated only with the doors fully open or doors fully
closed. If doors are left partly open, gas and ame may be drawn out of the replace opening, creating risks
of both re and smoke.
All replace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when
the replace is not in use, cold air can fall down the chimney of the replace to cool off the replace chase.
Therefore, the replace chase must be insulated to minimize the risk of cold air inltration to the home.
Even if the replace chase is adequately insulated, this cannot completely ensure that cold air inltration
into the structure will be eliminated. Cold air inltration is a possibility with any replace or device that freely
communicates with the air on the outside of the structure. Today’s homes are more energy-efcient and,
therefore, better insulated and tightly constructed. Unfortunately, when air is removed from the house, as by
a bathroom fan, or consumed by a furnace, additional air is needed to replace the air consumed. Unless the
additional air is supplied, this can cause a negative pressure in the home. When this happens, the house will
draw in outside air form the cracks in the windows, down the replace ue or other locations of air leakage in
the home. Because cold air inltration may be unavoidable in some structures, MHSC is not responsible for
heat loss or air inltration through or around the replace.

FiReplace location
CAUTION: Do not install replace over carpeting.
This replace does not weigh more than large pieces of furniture and can normally be located near a load
bearing wall without requiring additional foundations or supports. If however, the replace is to be trimmed
with a heavy stone or brick facing and hearth extension, be sure the supporting structure is adequate.
Figures 5 and 6 provide dimensional details of the replace, required spacing to combustible walls, and some
suggested replace locations. When selecting a location, choose one that is away from frequently opened
doors, central heat outlets or returns, or other places where air movements may disturb the airow around the
replace. Air turbulence near the replace may cause smoke to spill out of the replace opening.

Survey the planned location for the replace for overhead plumbing or electrical wires, etc., that might complicate
the installation or endanger persons installing or cleaning the chimney. Avoid a location where the chimney
cap will be near abrupt changes in the roof shape, nearby wall or embankments, under or near trees or above
the roof of a single story wing of a two story building as shown by Figure 9. All these conditions can cause
turbulence or pressure conditions that can cause poor chimney draft and smoke spillage from the replace
opening. Elbows may be used to offset the chimney to avoid obstructions or to locate the chimney cap in a
preferred location. Refer to the sections of this manual pertaining to chimney offsets for instructions on proper
elbow use. Poor installation or location of the chimney cap and/or components can cause wind blown rain to
enter the chimney.
Be sure the selected location will allow a 17” square combustible material-free space for the chimney to pass
through. If the chimney is to pass through living or storage spaces, be sure there is adequate space to enclose
the chimney to avoid personal contact with, or damage to, the chimney. If the replace is to be installed on an
outside wall, the surrounding walls (chase) should be constructed and insulated as shown by Figure 7. Failure
to insulate the replace form outside temperatures will cause heat loss through and around the replace.

If this replace is installed on a combustible oor, the oor area 20 inches in front of, and 12 inches either side
of the replace opening must be protected by an insulating noncombustible hearth extension. This hearth
extension may be either minimum 6-inch thick stone or brick as shown by Figure 11, an H2068 hearth exten-
sion kit or a locally constructed equivalent to the H2068.
The H2068 hearth extension kit consists of sufcient insulation board to cover the 20” x 68” oor area with ˚ inch
layer of insulation. A 20” x 68” piece of galvanized steel is included in the kit to cover the insulation before a
nishing layer of noncombustible material of stone, brick, tile, etc., is applied to nish the hearth extension.
The insulation used in the H2068 hearth extension has a thermal conductivity (K factor) of 0.43. If you do
construct a hearth extension equivalent to the H2068, be sure the insulation you use has enough compressive
strength to support the weight of the covering materials and persons standing on it, and insulating qualities
equal to or better than the 1/2” covering provided by the H2068.

The ability of insulating material to retard the transfer of heat may be expressed as either Thermal Conductance
(C), Thermal Conductivity (K), or Thermal Resistance (R). The mathematical relationship of these values and
the formulas for converting one value to another is as follows:
C=K divided by the material thickness
(Example C = .43 divided by 1/2 (.50)
C = .86)
K = C multiplies by the material thickness
(Example K = .86 multiplied by 1/2 (.50)
K = .43)
R= The material thickness divided by K
(Example R = 1/2 (.50) divided by .43
R = 1.16)
With either type hearth extension minor shifting of the supporting oor or expansion and contraction may
eventually cause a crack to develop between the hearth extension and the face of the replace. To help
prevent the crack from developing, the hearth extension materials must be rmly fastened in place. Wall ties
should be screwed to the face of the replace and imbedded in the mortar joints of brick, stone, or other non-
combustible materials. The metal safety strip packed with the replace must be placed beneath the replace
and extended under the hearth extension or into a mortar joint of the hearth extension as shown by Figures
11, 13, and 14. In the event a crack does eventually develop, the metal safety strip will serve as a barrier to
prevent sparks or embers from falling from the replace onto combustible ooring materials.

location selection
Unpack and check the replace and chimney for damage. If any items have been damaged, report this to
your dealer. Before beginning the installation, be sure you have the proper parts in sufcient quantity. Refer
to Figure 28 for proper identication of parts.
Do not substitute parts. Use only parts listed for use with the Model SB5400SS replace.
FiReplace installation
1. Refer to Figure 1 for an example of a typical installation of the replace components.
2. Be sure the location of the replace will provide the required clearances indicated by Figures 2, 3, & 5 and
the minimum chimney air space clearance to combustibles of two inches.
3. Set the replace in the desired location and be sure it is securely supported and leveled. Check the face
of the replace with a carpenter’s level and if it is not plumb; correct it by placing shims under the edges
of the replace.
4. Block in the replace to prevent any shifting of the rebox. Secure the replace with nails or screws through
the anges located on each side of the replace. Do not enclose the replace until the combustion air duct
and chimney pipes are installed.
NOTE: Some local codes may require electrically grounding the replace and chimney.
chiMney installation
In order to assure safe and satisfactory performance of the replace, it is very important to properly install the
chimney. This is an important part of the installation and the sections of this manual pertaining to chimney
installation should be reviewed very thoroughly.
For your safety, some of the important things to remember in regard to chimneys are listed below:
1. Use only parts and accessories labeled for use with this replace.
2. Use only undamaged parts and accessories.
3. Enclose the chimney where it passes through the living spaces to prevent contact with and possible dam-
age to the chimney.
4. Install restop spacers at each ceiling level.
5. Install the proper chimney cap or chimney housing on the chimney to prevent the entry of rain and debris
into the chimney and to assure the proper venting of smoke.
6. Do not use more than four elbows in the chimney.
NOTE: To select the proper chimney height, refer to Figure 1. The ue outlet must be a minimum of three feet
above the highest point where the chimney penetrates the roof and a minimum of two feet above all portions
of the building within ten feet. If the chimney is to include elbows to offset the chimney, refer to the Chimney
Offset and Cap Installation section of this manual. There must be at least two inches air space between all
sections of the chimney and combustible materials between oors.

chiMney installation
1. Lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass
through. Unless the chimney is to be offset, the point where the center line of the chimney will pass through
the ceiling and roof can be determined with a plumb line as shown by Figure 17. The replace should
be located in the planned installation position. After the center line is established and a nail is driven to
mark the point, the opening can be cut if you are satised with the chimney location relative to ceiling and
roof joists and/or any other obstructions. The roof opening center line should be marked by driving a
nail through the roof from underneath that will penetrate the roof and can be located from the rooftop. If
the chimney is to penetrate a pitched roof, the hole in the roof must be rectangular instead of square and
should be sized according to Table1.
2. Install the restop spacer as required from beneath the ceiling unless the space above is attic space. In an
attic, the restop spacer should be installed at the oor level of the attic. You must have joists or headers
on all four sides of the spacer and use a minimum of four 8-penney nails to secure the spacer.
3. To install the “L” series chimney sections, insert the male end of the ue, the smallest diameter pipe, into
the ue outlet of the replace and press down until the snap locks engage. Continue the process, adding
the chimney sections on top of each other until the chimney is at least six inches above the roof opening
on all sided. As the chimney sections are installed, check each joint to make sure it is properly locked to
the previous section. If additional strength of the outer pipe joints is desired, you may use two or three
sheet metal screws placed through the area where the outer pipes overlap one another. To install these
screws, drill a 1/8-inch diameter hole through the chimney sections, taking care not to penetrate the inner
ue pipe. Warning: Be very careful when drilling the holes into the outer pipe. The drill must not penetrate
the inner stainless steel pipe.
NOTE: If you intend to have a total replace installation of more that 30 feet you must use chimney support
model LCS at or below 30 feet to support the weight of additional chimney pipe.
To install the chimney support, place the crimped end of the ue and outlet air duct portions into the last sec-
tion of chimney pipe. Push down until the outside or inlet air duct of the chimney support overlaps and snap
locks the chimney support into the chimney section.
Nail the support straps tightly to a building frame member or ceiling joist as shown by Figure 18. You must
use at least two 8-penney nails per strap.

NOTE:
FLUE OUTLET SHOULD BE TWO FEET ABOVE ALL PORTIONS OF THE BUILDING
WITHIN TEN FEET AS SHOWN IN THE ILLUSTRATION. THE CHIMNEY MUST NOT
EXTEND MORE THAN 90 INCHES ABOVE THE ROOF WITHOUT ADDITIONAL SUPPORT.

elbow installation
The following are important points that should be observed when installing elbows on the replace:
1. The support straps of all elbows not installed directly on top of the replace should be nailed securely to the
surrounding structure. This allows the support strap to carry the weight of the chimney above the elbow
and prevents this weight from breaking the elbow or chimney sections apart.
2. Elbows should not be used in any combination that inclines the chimney more than 30 degrees from
vertical.
3. The limitations on the quantity of elbows per chimney are as follows: If the total height of the replace and
chimney is—12’ - 2” or more — two elbows may be used in the chimney. 21’ - 0” or more — four elbows
may be used in the chimney.
4. The inclined portions of chimneys that pass through living spaces likely to be used for storage should be
enclosed to avoid contact with and possible damage to the chimney. The minimum air space of two inches
between the chimney and enclosing materials must be maintained.
5. The length of the inclined portion of chimney between elbows must not exceed 6 feet when unsupported
or 20 feet if the chimney is supported at six-foot intervals with support such as metal support straps.
6. When enclosing the elbows and inclined portions of the chimney, enclosing materials must be installed
vertically to maintain the required two-inch minimum air space clearance to the chimney at the extremities
of the offset. It is recommended that enclosing material not follow the inclined portions of the chimney.
oFFset installation sequence
1. Determine the location and amount of offset required, then select the combinations of chimney sections
and elbows required from the offset chart. Refer to Page 19.
2. Install the rst LE30 elbow by placing the extended ue into the mating part of the replace or chimney
section. Push down until the outside or inlet air duct of the elbow overlaps and the snaps lock the elbow
into the replace or chimney section.
3. Nail the support straps to the framing member with a minimum of two 8-penny nails per strap.
4. Install the sections of pipe between elbows until the proper number of chimney sections have been
installed.
5. Install the second elbow to return the run of the chimney to vertical.
6. Nail the support straps of the second elbow to a building frame member.
7. Continue installing the vertical portion of the chimney.
NOTE: If the inclined portion of the chimney passes through a oor or ceiling, an LF-FS-30 restop spacer
should be installed to provide the restop and support required. Be sure proper spacing in maintained between
the chimney and combustibles.

chiMney cap installation
Model lc chiMney cap
special note: The proper height as previously explained is important to assure proper draft and safety. The
chimney cap extends the ue outlet four inches above the top of the last section of chimney. This should be
kept in mind when determining the proper height for the chimney. The chimney should not be extended more
than 90 inches above the supporting roof structure without additional support. In the case of an “A” frame type
construction or other steep pitch roofs that require more than 90 inches of chimney above the roof, a support
should be attached to the chimney at the 90 inch level that is strong enough to support a wind load of 3-1/8
pounds for each inch the chimney extends above 90 inches. The ue outlet must be a minimum of three feet
above the point where in penetrates the roof.
caution: Be careful to avoid electrical shock hazard when contacting wires to the metal chimney
components.
1. Extend the regular chimney sections until the top of the chimney is 4 inches below the total ue height
desired. Do not snap the last section of inlet air duct or largest diameter pipe in place until Step 3 is
completed.
2. Remove the shingles from around the chimney so that the ashing may be installed, with the upper part
of the ashing under the shingles.
3. Set the ashing on the roof. Hold a section of the outside pipe (13” diameter) on the ashing and scribe
a line around the ashing, then cut the top off the ashing by cutting 1/4 inch below the scribed line. This
should increase the diameter of the ashing outlet sufciently to allow the ashing to be placed over the
chimney. See Figure 21.
4. Snap the last section of inlet air duct in place and slide the ashing over the chimney. Adjust the chimney
to assure that the proper minimum clearances are maintained.
5. Nail the ashing securely in place with eight nails.
6. Seal the crack between the top of the ashing and the chimney with mastic. Leave some excess mastic
at this area to be used in step eight. NOTE: Use pliers and wear gloves when performing step seven to
minimize the danger of cutting your hands on the edge of the storm collar.
7. Place the storm collar around the chimney and put the collar together like a belt in belt loops. Slide the
end of collar under the two loops on the other end with the loops facing up. Overlap the ends of the collar
until it is tight against the chimney. Bend the free end of the collar back over the loops to hold the storm
collar securely together. The excess end of the storm collar may be trimmed off.
8. Slide the storm collar down snugly against the ashing until the excess mastic left in step six is forced up
into the crack between the storm collar and the chimney. This should make the joint between the ashing
and the chimney watertight.
9. Install the chimney cap by placing the cap into matching parts of the last chimney section. Then punch or
drill 1/8 inch diameter holes in the inlet air duct (chimney pipe) where specied on the brackets and fasten
it down with the No. 8 screws provided. Do not penetrate the inner stainless steel pipe while installing the
screws.
10. Check all the parts of the replace, chimney and chimney termination cap to assure that no parts have
been damaged or bent during installation and that all parts have been installed properly.
note: The metal used for the chimney cap has a rust protective coating but the cut edges of the parts are
not protected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney and
chimney cap should be detergent washed and painted with a galvanized primer paint.

note FoR stRaight Run chiMneys:
Chimney support required at 25’ chimney height.
notes FoR chiMneys with elbow oFFsets:
The length of the inclined portion of the chimney between
elbows must not exceed 6 feet when unsupported, or 20 feet
if the chimney is supported at 6 foot intervals using either
metal support straps or an LCS chimney support.
The LCS chimney support when installed at a 30 degree
angle will add 8” of rise and 4-5/8” of offset to the chimney
height calculations.
