OPERATION GUIDELINES  
5
When a AK4 combustion air assembly and a combustion air duct are attached to the connecting point on the  
left of the fireplace, combustion air may enter the firebox through a dampered opening behind the left side panel.  
This feature is designed for your benefit to reduce the room air used for combustion and to prevent excessive  
loss of heat from the room. When the fireplace is in use, this damper should be open. When the fireplace is not  
in use, the damper should be closed to prevent cold air from entering the firebox. The combustion air damper  
is open when the lever, located on the left side of the firebox near the top of the left firebrick, 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  
fireplace allows the routing of the combustion air duct up, down, or horizontally to obtain the outside combustion  
air. This permits flexibility 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 benefit from your fireplace. For large fires, the maximum  
heating benefit from the fireplace will be obtained with the doors open due to the high amount of radiant heat  
being emitted out of the front opening of the fireplace. With a small fire, or before retiring in the evenings, it is  
best to operate the fireplace 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 firebox.  
The fireplace should also be equipped with a flue damper, which must be open when the fireplace is in use. The  
flue damper control lever is located inside the fireplace. The counterweighted damper is operated by simply  
pushing up to open or pulling down to close the damper. When the fireplace 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 fireplace the first  
few times you use your new fireplace. 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 fireplace helps to appropriately locate and contain the burning wood. Failure to use  
this grate may cause overheating of parts of the fireplace and allow large pieces of burning wood to roll forward  
out of the firebox. 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 flame may be drawn out of the fireplace opening, creating risks of  
both fire and smoke.  
All fireplace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when  
the fireplace is not in use, cold air can fall down the chimney of the fireplace to cool off the fireplace chase.  
Therefore, the fireplace chase must be insulated to minimize the risk of cold air infiltration to the home. Even if  
the fireplace chase is adequately insulated, this cannot completely ensure that cold air infiltration into the  
structure will be eliminated. Cold air infiltration is a possibility with any fireplace or device that freely communicates  
with the air on the outside of the structure. Today’s homes are more energy-efficient 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 fireplace flue or other locations of air leakage in the home.  
Because cold air infiltration may be unavoidable in some structures, Martin Hearth & Heating is not responsible  
for heat loss or air infiltration through or around the fireplace.

FIREPLACE LOCATION  
CAUTION: Do not install fireplace over carpeting.  
This fireplace 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 fireplace 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 fireplace, required spacing to combustible walls, and some  
suggested fireplace 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 airflow around the  
fireplace. Air turbulence near the fireplace may cause smoke to spill out of the fireplace opening.

INSTALLATION PREPARATION  
Survey the planned location for the fireplace 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 fireplace  
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 fireplace 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 fireplace form outside temperatures will cause heat loss through and around the fireplace.

FLOOR PROTECTION  
If this fireplace is installed on a combustible floor, the floor area 20 inches in front of, and 12 inches either side  
of the fireplace 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 sufficient insulation board to cover the 20" x 68" floor 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 finishing layer of noncombustible material of stone, brick, tile, etc., is applied to finish 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.

FLOOR PROTECTION  
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)

With either type hearth extension minor shifting of the supporting floor or expansion and contraction may  
eventually cause a crack to develop between the hearth extension and the face of the fireplace. To help  
prevent the crack from developing, the hearth extension materials must be firmly fastened in place. Wall ties  
should be screwed to the face of the fireplace and imbedded in the mortar joints of brick, stone, or other non-  
combustible materials. The metal safety strip packed with the fireplace must be placed beneath the fireplace  
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 fireplace onto combustible flooring materials.

FIREPLACE INSTALLATION  
LOCATION SELECTION  
Unpack and check the fireplace 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 sufficient quantity. Refer to  
Figure 28 for proper identification of parts.  
Do not substitute parts. Use only parts listed for use with the Model SB5400SS fireplace.  
FIREPLACE INSTALLATION  
1. Refer to Figure 1 for an example of a typical installation of the fireplace components.  
2. Be sure the location of the fireplace 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 fireplace in the desired location and be sure it is securely supported and leveled. Check the face of  
the fireplace with a carpenter’s level and if it is not plumb; correct it by placing shims under the edges of the  
fireplace.  
4. Block in the fireplace to prevent any shifting of the firebox. Secure the fireplace with nails or screws  
through the flanges located on each side of the fireplace. Do not enclose the fireplace until the combustion  
air duct and chimney pipes are installed.  
NOTE: Some local codes may require electrically grounding the fireplace and chimney.  
CHIMNEY INSTALLATION  
In order to assure safe and satisfactory performance of the fireplace, 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 fireplace.  
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 firestop 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 flue 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 floors.

WITHIN TEN FEET AS SHOWN IN THE ILLUSTRATION. THE CHIMNEY MUST NOT  
EXTEND MORE THAN 90 INCHES ABOVE THE ROOF WITHOUT ADDITIONAL SUPPORT.  
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 fireplace 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 satisfied 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 firestop spacer as required from beneath the ceiling unless the space above is attic space. In an  
attic, the firestop spacer should be installed at the floor 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 flue, the smallest diameter pipe, into the  
flue outlet of the fireplace 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 flue 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 fireplace 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 flue and outlet air duct portions into the last section  
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.

CHIMNEY OFFSET INSTALLATION  
ELBOW INSTALLATION  
The following are important points that should be observed when installing elbows on the fireplace:  
1. The support straps of all elbows not installed directly on top of the fireplace 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.  
ALL FOUR SUPPORT  
STRAPS MUST BE NAILED  
ON TO FRAMING MEMBER  
NOTE:  
30˚ ELBOW

ADDED STABILIZATION OF PIPE  
3. The limitations on the quantity of elbows per chimney are as follows: If the total height of the fireplace 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 first LE30 elbow by placing the extended flue into the mating part of the fireplace or chimney  
section. Push down until the outside or inlet air duct of the elbow overlaps and the snaps lock the elbow into  
the fireplace 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 floor or ceiling, an LF-FS-30 firestop spacer  
should be installed to provide the firestop 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 flue 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 flue 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 flue 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 flashing may be installed, with the upper part of  
the flashing under the shingles.  
3. Set the flashing on the roof. Hold a section of the outside pipe (13" diameter) on the flashing and scribe a  
line around the flashing, then cut the top off the flashing by cutting 1/4 inch below the scribed line. This  
should increase the diameter of the flashing outlet sufficiently to allow the flashing to be placed over the  
chimney. See Figure 21.  
4. Snap the last section of inlet air duct in place and slide the flashing over the chimney. Adjust the chimney  
to assure that the proper minimum clearances are maintained.  
5. Nail the flashing securely in place with eight nails.  
6. Seal the crack between the top of the flashing 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 flashing 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 flashing  
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 specified 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 fireplace, 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.

CHIMNEY CAP CHASE INSTALLATION  
The preinstalled chimney sections should be no more than 13 inches below the top of the chase. The installation  
should be planned so that either a two-foot or three-foot chimney section will be used for the top section. This  
is necessary to ensure complete engagement of the inlet air telescope and chimney cap into the top section.  
1. Extend the chimney sections until the top of the chimney is not more than 13 inches below the top of the  
chase.  
2. Center the hole in the chase cover over the chimney. The chase cover overhang should be lanced, formed  
over the chase and secured with nails. This prevents water from seeping under the chase cover. If two or  
more chase covers are to be used on the same chase, they should be soldered together to form two  
watertight seams.  
3. Place the outer telescope inside the hole in the chase cover and lower it down into the mating pipe of the  
chimney until the support brackets on the telescope section rest on the flange of the chase cover.  
4. Bend the tab with a hole on each bracket outward and secure cap to flashing, using the tabs provided.  
5. Once the telescope is secured, place the rain shield over the top of the telescope pipe assembly. The rain  
shield will be supported by the telescope brackets.  
CAUTION: Be careful around electrical wires to avoid the electrical shock hazard of contacting the wires with the  
metal chimney components.  
NOTE: When two fireplace chimneys are terminated above the same chase, the centers of the chimney caps  
should be at least 24 inches apart to help prevent smoke from a fireplace in use from being drawn down the  
chimney of a fireplace that is not in use. Additional spacing between caps or staggering the height of the caps  
will further lessen the likelihood of this occurring.  
6. Place LCL cap assembly into position by aligning the flue telescope into the last section of flue pipe and  
lower it down until the 3 cap legs rest on the top edge of the outer telescope pipe. Secure legs of cap to the  
telescope with screws provided.  
7. Check all parts of the chimney and chimney 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 and 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 galvanized primer paint.

OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS  
OUTSIDE COMBUSTION AIR RECOMMENDATIONS (CONTINUED)  
1. Extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air assembly  
should be avoided. These conditions will increase the resistance to the free flow of air through the duct.  
Refer to Figures 1, 23, and 24 for methods of installing the outside air for combustion assemblies.  
2. The combustion air assembly should be located at an exterior location, which is not likely to be accidentally  
blocked in any manner. The assembly should be located above the snow line to prevent blockage by snow  
accumulation.  
3. The combustion air inlet assembly should never be mounted in a garage or storage area where combustible  
fumes such as gasoline might be drawn into the fireplace.  
4. Combustion air can be drawn form the crawl space under a house when an adequate supply of air is  
provided by open ventilation.  
5. Do not take combustion air from attic space or garage space.

COMBUSTION AIR ASSEMBLY  
MODEL AK-4 COMBUSTION AIR ASSEMBLY  
1. Remove the cover plate from the 4-inch outlet opening location on the left outside of the fireplace. DO NOT  
remove the cover if the outside air will not be connected.  
2. Place the insulation ring between the AK-4 starting collar and fireplace wall and place the starting collar (4  
inch) into the hole on the left side of the fireplace. Fasten it in place with the four sheet metal screws  
provided.  
3. Cut a 6-inch diameter opening for model AK-4 in the outside wall covering where the outside vent is to be  
located.  
4. Select and cut a piece of duct sufficient length to attach to the fireplace and protrude at least three inches  
beyond the face of the wall to which the AK-4 inlet air vent will be attached. The duct may be cut with a  
standard pocket knife (use FP-4 U duct for maximum efficiency and safety). Do not use a combustible  
duct. Always use UL Listed Class 0 or 1 duct material.  
5. If the duct is the insulated type, push the insulation back from one end of the duct approximately two  
inches.  
6. Slip the exposed end of the duct over the starting collar on the fireplace.  
7. Using the sheet metal screws provided, secure the duct end to the collar attached to the fireplace.  
8. Nail or screw the combustion air assembly to the surface of the wall.  
NOTE: If the wall covering is brick or stone, use appropriate masonry fasteners. Mount the combustion air  
assembly with “TOP’” upward to prevent cold air from entering through the wall. If it is necessary to splice the  
duct, a model 403-duct connector should be used to splice duct sections.

GAS APPLIANCE INSTALLATION  
WARNING: Improper installation or operation of a gas appliance in this fireplace can allow unburned gas to leak  
out which will cause a fire or explosion hazard, or the release of poisonous carbon monoxide into the dwelling  
which can cause serious injury or death to its inhabitants. To reduce these risks to a minimum, the following  
important notices and instructions should be read and followed carefully.  
IMPORTANT NOTICES:  
1. The provision for a gas line is intended for connection to a decorative gas appliance which and complies  
with the Standard for Decorative Gas Appliances for Installation in Vented Fireplaces, ANSIZ21.60. If a  
decorative gas appliance is installed, it must be installed in accordance with the National Fuel Gas Code,  
ANSIZ223.1.  
CAUTION: “When a decorative gas appliance is installed, the fireplace damper must be fixed in a manner  
which will maintain the minimum permanent vent opening at all times."  
If an unvented gas appliance (blue flame) is installed it must incorporate an automatic shutoff device, and  
must be installed in accordance with with the National Fuel Gas Code Z223.1, Latest edition.  
CAUTION: If an unvented gas appliance is installed in the fireplace, the gas appliance must only be operated  
with the fireplace glass door fully open (if included). Only unvented gas log set which have been found to  
comply with the standard for unvented room heaters, ANSI/IAS/AGA Z21.11.2, are to be installed in this  
fireplace. When an approved ANSI/IAS/AGA Z21.11.2 unvented room heater is installed in this fireplace,  
a H2853 CANOPY must also be installed.  
WARNING: Do not operate an unvented gas log set in this fireplace with the chimney removed.  
The installer of the fireplace and gas appliance must describe the operation of the fireplace and appliance  
to the people who will be operating them and leave all instruction manuals with the operator of the appliance.  
2. An approved gas shut off valve must be located outside the fireplace in an area accessible to the users of  
the fireplace.  
3. All gas piping and fitting must be either steel or malleable iron. Unions must be of the ground joint type.  
4. Some code authorities prohibit or place restrictions on the use of gas appliances in fireplaces. Check with  
local code authorities before proceeding with the installation.  
5. The gas appliance and all connecting gas piping should only be installed by a licensed gas appliance  
installer.  
The following instructions only apply to passing the gas line through the fireplace wall. Follow the instructions  
provided by the appliance for the gas line, testing and adjusting it.  
1. Locate the recessed area in the side refractory panel as shown by Figure 25.  
2. Tap out a round hole in the brick liner with a hammer by tapping lightly on the recessed area.  
3. Remove the two screws that hold the cover plates on the jacket wrap and discard the cover plate.  
4. Use a screwdriver or similar tool to push the loose insulation out of the tube between the firebox and the  
outer jacket of the fireplace.  
5. Install the gas pipe through the tube between the firebox and jacket.

APPLYING DECORATIVE TRIM TO THE FIREPLACE  
Do not allow the trim materials to extend closer than 3/8 inch to the vertical edges of the firebox opening if you  
plan to equip the fireplace with glass doors.  
The face of your fireplace may be left exposed or trimmed with any noncombustible material such as brick,  
stone or marble. If a trim is installed, be sure it is fastened snugly to the face of the fireplace. A crack between  
the material and the face of the fireplace could pose a fire hazard and impair the proper operation of the  
fireplace. Blocking the fireplace with framing and attaching the base to the supporting floor will further reduce  
the possibility of such a crack developing.  
Wall ties should be fastened to the face of the fireplace with sheet metal screws and placed in the mortar joints  
of masonry trim.  
Combustible material must not be installed below the top spacers of the fireplace or overlap the sides of the  
fireplace face. Seal the face of the fireplace to the surrounding wall with non-combustible caulk or trim materials  
to prevent cold air leakage around the fireplace.  
The trim should not block or restrict in any way the flow of air into the side air inlets in the face of the fireplace.  
Be sure to provide the required floor protection as described in a preceding section of this manual.  
Combustible mantles and trim must be installed in accordance with the National Fire Protection Association -  
ANSI NFPA 211 Standard - Section 7-2.3.3.

FIREPLACE OPERATION  
WARNING: If a decorative gas appliance is used in the fireplace the fireplace damper must be fixed in an open  
position. (See additional operation information in section titled “Operation Guidelines”.)  
ADVANTAGES OF A WOOD BURNING FIREPLACE  
These are the practical, ecological advantages of wood as a fuel. Also to be considered is the aesthetic  
appeal. Most of us consider a wood fire with nostalgia. We enjoy the aroma, and find the flickering light of a  
cozy hearth conductive to a happy remembrance of things past. Wood has a low ash content. And the little  
ash that remains after burning is useful in home gardening as a fertilizer and soil conditioner.  
WARNING: This appliance is not for use as cooking equipment.  
WHICH WOODS ARE BEST?  
Each wood species offers something different in aroma or heat value, and you should consider your needs and  
desires before building your fire.  
Softwoods, like pine, spruce, and fir are easy to ignite because they are resinous. However, a fire built entirely  
of softwoods burns out quickly and requires frequent replenishment. While a softwood fire is not too desirable  
for a long evening, it’s fine in the morning when you want quick warmth, or late in the evening when you want a  
fire that will burn out before you go to bed.  
On occasion when a longer fire is desired, it’s best to combine softwoods with the heavier hardwoods such as  
ash, beech, birch, maple, oak and hickory. These hardwood species burn less rapidly, with shorter flames,  
and produce steady, glowing coals.  
For the most pleasing aroma, you’ll want to burn the wood of fruit trees such as apple and cherry, or nut trees  
such as beech, hickory and pecan. Such wood is generally more expensive, but a little combined with other  
wood, goes a long way. Start your fire with a mixture of softwood and hardwood, then add some fruit or nut  
wood for nostalgic aroma. Since most woods will not burn well when freshly cut, the wood you purchase  
should be reasonably dry. The sizes you buy are dictated by the size of your fireplace. Purchase logs that will  
fit when laid across your grate, and ask that the larger, heavier logs be split. Kindling should be short, easily  
split lengths of softwood, lumber yard or mill scraps, or twigs and branches gathered from your yard.  
HOW TO BUILD A BETTER FIRE  
The first three fires should be of moderate size to allow the fireplace to adjust and the bricks to cure before  
being subjected to larger fires.  
First, make sure your room is well ventilated, your damper open and the flue is unobstructed. Then make sure  
your wood is dry and seasoned. Unseasoned wood burns poorly and coupled with poor ventilation or an  
obstructed chimney, leads to smoking problems.  
If your fireplace is equipped with an outside combustion air assembly, open the combustion air inlet by pushing  
upward on the lever located above the firebrick on the left side of the firebox.  
NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR  
"FRESHEN UP" A FIRE IN THIS FIREPLACE. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE FIREPLACE WHILE IT IS IN USE. USE OF THIS  
FUEL CAN CAUSE A SERIOUS EXPLOSION.  
Prepare your fire by placing two logs on the iron grate or fire basket, and laying the tinder between them. Tinder  
may be dry scrap paper, twigs, or bark. On top place a small handful of twigs or split softwood kindling. Place  
more dry logs over this base. Keep logs close together, as narrow air spaces between them promote better  
drafts, and heat reflected between adjacent surfaces aids in raising and maintaining combustion temperatures.  
27  
53D9028. Rev 1 03/03  
Download from Www.Somanuals.com. All Manuals Search And Download.  
FIREPLACE OPERATION  
You’ll need a minimum of three logs, preferably four, to make a good fire. Add kindling and new logs as needed  
to rekindle a dying fire. New logs should be added at the rear grate after raking the coals toward the front. DO  
NOT OVERFIRE THE FIREPLACE. Overfire conditions may be created by large amounts of kindling, building scraps,  
or other improper fuels.  
Ashes, important because they form a bed of glowing coals, should only be left to accumulate within an inch or  
two of the bottom of the grate. Excess ashes can be used to check a flaming fire; or to “bank” your fire, cover  
the logs with ashes. A “banked” fire will hold glowing coals for 8-10 hours, thereby saving a fire for later use.  
WOOD VS. FOSSIL FUELS  
Compared to fossil fuels, a full cord of dry hickory weighs about two tons and is approximately equal in heating  
value to a ton of hard coal. On a pound basis, heavy hardwoods have about half the heating value of coal. The  
tabulation shows the relative densities and heat values of a variety of dry woods. Varieties at the top of the list  
(Dogwood) burn longer and those near the bottom (White Pine) ignite and burn quicker. A combination of both  
light and heavy wood is desired.

A FEW WORDS OF CAUTION  
Beware of burning certain material in your fireplace. Among these are plastics, poison ivy twigs and stems,  
and chemically treated woods such as discarded poles and railroad ties. These not only create air pollution,  
but can induce extreme irritation for some individuals.  
Use hemlock, spruce, juniper and other resinous woods with caution. They contain moisture pockets which,  
upon heating, “pop” with considerable vigor.  
Always use a fire screen. And always “bank” a fire, or at least push all unburned fuel to the rear of the grate  
before leaving a fire unattended. Do not use this fireplace as an incinerator.  
Because the termination of the chimney above the roof is exposed to wind and cold and the pressure changes  
these and other environmental conditions may cause, a sufficient chimney draft may be hard to establish at  
times. At other times the draft may be sufficiently disrupted to cause smoke to spill from the fireplace opening.  
If problems with chimney draft occur, help start chimney draft before you build a fire by holding a piece of  
burning paper near the flue opening at the top of the firebox to preheat the chimney. If smoke spills from the  
fireplace opening after the fire is burning, open a window on the up wind side of the house that is far enough  
away form the fireplace that the wind will not blow across the fireplace opening, push the burning wood as near  
the back of the fireplace as possible, and if the fireplace is equipped with glass doors, close them.  
DO NOT LEAVE CHILDREN OR PHYSICALLY OR MENTALLY HANDICAPPED, OR SENILE PERSONS  
ALONE WITH A BURNING FIREPLACE.

MAINTENANCE AND SAFETY  
FUEL STORAGE  
Wood can be dried sufficiently for burning within a few weeks if protected form rain in a low humidity area. It is  
far better to cut wood and allow it to dry for a year. In all cases, the wood should be stacked so that both ends  
of the sticks are exposed to the air and protected from rain. The drier the wood, the more usable heat produced  
by the fire and less likely rapid accumulation of soot and creosote within the chimney is to occur. See the  
section of this manual concerning chimney maintenance for information concerning the hazards of soot a  
creosote accumulation. Small quantities of wood required for fire tending must be kept at least 30 inches from  
the fireplace.  
DISPOSAL OF ASHES  
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be  
placed on a noncombustible floor or on the ground well away from all combustible materials pending final  
disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained  
in the closed container until all cinder has thoroughly cooled. Ashes should never be placed in a container with  
combustible materials.  
CHIMNEY MAINTENANCE  
Creosote, Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic  
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively  
cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When  
ignited, this creosote makes an extremely hot fire.  
The chimney should be inspected at least twice a year during the heating season to determine if a creosote  
buildup has occurred.  
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.  
The chimney cap can be removed for inspection, maintenance and cleaning by removing three screws from  
the support legs and lifting upward.  
When the fireplace is first in use, inspect the chimney frequently and clean the chimney any time an accumulation  
is observed on the flue walls. The frequency of these inspections can be increased or reduced appropriately  
after a pattern of accumulation has been established. Please note, however, that changes in the outside  
environmental conditions such as temperature and humidity or changes in the operation of the fireplace can  
lead to rapid buildup of soot and/or creosote.  
To clean the chimney, obtain the services of a qualified and reputable chimney sweep, or remove the accumulation  
with brushes on wooden or fiberglass poles. Do not use metal pipes, chains, wires, etc., to clean the chimney  
because such items can scratch the surface of the stainless steel flue which can shorten the life of the flue and  
provide a rough surface for soot particles to attach to.  
Be sure to cover nearby furnishing and arrange some method of catching soot and creosote particles that may  
fall during the chimney cleaning process. If glass doors are installed on the fireplace, they should be closed.  
Extra caution must be used to avoid damage to the flue damper during the cleaning process.  
In addition to checking and cleaning the chimney on a regular basis, be sure to inspect the chimney before  
starting a fire at the beginning of each heating season. Make sure the chimney is clear from any accumulation  
of soot, creosote or any other debris, and that all joints are intact.  
Martin Hearth & Heating does not recommend chemical cleaners because some may contain elements that  
corrode the metal parts of the chimney or fireplace.

MAINTENANCE AND SAFETY  
FIREPLACE MAINTENANCE  
At the end of each heating season or when the fireplace will not be in use for an extended time, the ashes  
should be removed and the hearth area should be swept as clean as is practical. The slow absorption of  
moisture into the ashes over a long period of time could cause a condition which would be corrosive to the  
metal fireplace parts.  
At the beginning of each heating season, always operate the flue damper and make sure it has not become  
stuck from soot, creosote, etc., during the period of inactivity.  
Keep the lower and upper grille panels clean and free from dirt and lint accumulation at all times to get the  
maximum efficiency from your fireplace.  
As you use the fireplace, expansion and contraction will cause minor cracking of the hearth, back, and side  
refractory materials. This is normal and unavoidable. If the cracks become large enough or parts dislodge and  
metal behind the refractory is exposed, the refractory panels should be replaced with new panels that can be  
obtained from you fireplace dealer.  
GLASS DOOR MAINTENANCE  
For glass door maintenance, see instructions provided with the glass doors.
