WARNING: Do not install in a sleeping room of a mobile home.
CAUTION: If installed in a mobile home, the structural integrity of the ﬂoor, wall and ceiling/roof must be maintained.
WARNING: This ﬁreplace and chimney must not be used for venting a solid fuel heater or ﬁreplace insert unless written authorization is given by MHSC. Failure to heed this warning may cause ﬁre hazard and will void the warranty.

Improper Installation
Improper installation or use of this ﬁreplace will void the warranty and can cause:

Damage to the ﬁreplace from overheating.
Hazardous temperatures to develop on combustible materials adjacent to the ﬁreplace or chimney.
The emission of smoke, sparks or hazardous gases into the dwelling.
Leakage of rain water into the dwelling.

OPERATION GUIDELINES

As wood is burned in the ﬁreplace, room air enters the air slot on the lower front edge and circulates around the ﬁrebox.
The air circulation around the ﬁrebox serves to cool the ﬁreplace and must not be blocked in any manner. Blocking of the inlet slot or outlet louver will cause the ﬁrebox to reach hazardous temperatures. When an OAC4 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 dampened opening behind the 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 side of the ﬁrebox 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. 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 from 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 unique design of the ﬁreplace allows the routing of the combustion air duct downward, horizontally or upward to obtain the outside combustion air. This permits maximum ﬂexibility in planning your installation. Refer to Page 22, Figure 24 for typical installation methods. Be sure to review the precautions and recommendations in the section of this manual pertaining to outside combustion air assembly. The ﬁreplace is also 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.

WARNING: Fireplaces equipped with glass 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 ﬁre- place 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 ﬁre-place 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 from 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, MHSC is not responsible for heat loss or air inﬁltration through or around the ﬁreplace.

FIREPLACE FEATURES

NOTE: Combustible materials should not be installed below top spacer. Noncombustible materials such as brick or tile may be used to trim face of the ﬁreplace but should not cover any portion of the louvered panel or cool air inlet.

FIREPLACE LOCATION

CAUTION: Do not install ﬁreplace over carpeting.
This ﬁreplace does not require any special foundation. If the ﬁreplace is to be trimmed with large stone or brick facing, an adequate foundation is required to support these materials. Use Figures 5 and 6 as a guide for selecting a location and determining the space required for the ﬁreplace. The location for the ﬁreplace should be adjacent to the load bearing wall and away from objects that will create drafts that could disturb the normal ﬂow of air into the ﬁre. Such objects are frequently opened doors and central heat and air outlets and returns. Figure 4 illustrates various types of locations and installation and Figure 1 gives additional information concerning installation heights, construction details, and methods on installation. A location that requires cutting the least number of joists and rafters for the chimney installation will simplify and reduce installation cost. The opening required for passage of the chimney through the roof, ceilings and ﬂoors must be 17 inches square as indicated by Figures 6, 7 and 8. The 17 inch square opening provides for the installation of the model LF-FS-2 ﬁrestop spacer in a residential installation. Since the pitch of the roof inﬂuences the opening size required at the roof level, table 1 should be used as a guide for sizing the roof opening. Proper selection of a chimney outlet location is also important. Objects such as overhanging or nearby trees, adjacent building or embarkments or unusual roof designs can all create air turbulence and interfere with chimney performance and cause the ﬁreplace to spill smoke into the room. A factory-built ﬁreplace, properly installed in a single story wing of a multi-story building as shown in Figure 9, may be affected by environmental factors that will cause poor chimney draft and occasional spillage of smoke from the ﬁreplace opening. Although this occurs infrequently, location of the ﬁreplace in the preferred location as indicated by Figure 9 is recommended. If the chimney is to pass through living areas or spaces used for storage, be sure that it will be possible to enclose the chimney to prevent contact with and possible damage to the chimney. Elbows may be used to avoid obstructions such as electrical wires, water, or sewer pipes, attic fans, heating ducts, etc. Refer to the section of this manual concerning chimney offsets for proper elbow installation and use. If the failure is to be installed in an outside wall, the surrounding walls should be enclosed and insulated. Failure to properly enclose the ﬁreplace will cause a heat loss and diminish the ﬁreplace efﬁciency due to transfer of heat through the ﬁreplace to the outside.

FLOOR PROTECTION

All ﬁreplaces installed over a combustible ﬂoor must incorporate a noncombustible earth extension. It is required to protect the ﬂoor in front of the ﬁreplace from both radiant heat and sparks. Hearth extension dimensions should be determined by using the chart below. Use hearth extensions as il- lustrated in Figures 5, 10 and 11 or use an acceptable thickness of a durable noncombustible material with an equal or greater insulating value than K – .43 BTU in/ft2-HR-F°, or a thermal resistance that equals or exceeds R = 1.16. These materials should be covered with a decorative noncombustible veneer.

NOTE: Any noncombustible material with a K factor value that is less than .43, or whose R value is more than 1.16 or 1/2” thick material is acceptable.

HOW TO DETERMINE HEARTH EXTENSION REQUIREMENTS
The following information is provided to determine required thickness for any non-combustible material when either the K or R values are known. They are expressed as the following: K = BTU-in/ft2-HR-F° or R = HR-F°/BTU. These materials should be covered by a decorative noncombustible material such as tile, brick, stone or slate. To determine the thickness needed for a material other than those listed in the chart, use the following formulas to calculate that which will be an acceptable equivalent. The ability of insulating material to retard the transfer of heat may be expressed as either Thermal Con-ductance (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 multiplied 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 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 n the mortar joints of brick, stone or other noncombustible materials. The metal safety strip packed with the ﬁreplace must be placed beneath the ﬁre-place and extended under the hearth extension or into a mortar joint of the hearth extension. 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. Refer to Figure 5 for an alternate hearth extension using brick only.

WARNING: The space between the hearth extension and ﬁreplace must be sealed with a noncombustible material. When installing the hearth extension, be careful not to block the heat circulating air inlets (louvers, slots, etc.) Figure 5

Wall Protection
A model WS wall shield or an equivalent must be installed when the closed end of the ﬁreplace is closer than 24” from a wall perpendicular to the face of the ﬁreplace. Figures 10 and 11. The WS wall shield should be attached securely to the wall by driving nails or screws through it into the wall studs. The wall shield should be covered by a decorative noncombustible material such as brick, tile, slate, etc. The WS wall shield is constructed of 1” of Micore CV230 insulation board, manufactured by U.S. Gypsum Corporation, covered by a sheet of galvanized metal. An alternate insulating material with a K factor of .43 or lower can be used. Refer to the preceding section for instructions for selecting an alternate insulating material.

WARNING: If not installed, operated and maintained in accordance with the manufacturer’s instructions, this product could expose you to substances in fuel or from fuel combustion which can cause death or serious illness and which are known to the State of California to cause cancer, birth defects or other reproductive harm. Also, operation, installation and servicing of this product could expose you to airborne particles of glass wool ﬁbers known to the State of California to cause cancer through inhalation.

CLEARANCES

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 the Parts Diagram and List section of this manual for proper identification of parts. Do not substitute parts. Use only parts listed for use with Model B36LA and B36RA fireplaces.

Fireplace Installation

Refer to Figure 1 for examples of typical fireplace framing.
Be sure the location of the fireplace will provide the required safety clearances as specified by this instruction manual.
Set the fireplace in the desired location and be sure it is securely supported and leveled. Install metal safety strip for hearth extension as shown by Figures 10, 11 and 12. Check the face of the fireplace with a carpenter’s level to make sure the fireplace is plumb. If it is not plumb, plumb it by placing shims under the edges of the fireplace.
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. Install chimney and other fireplace components as needed.

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:

Use only parts and accessories labeled for use with this fireplace.
Use only undamaged parts and accessories.

MOBILE HOME INSTALLATION

WARNING: Operating doors in this position is incorrect.

CHIMNEY INSTALLATION

Enclose the chimney where it passes through the living spaces to prevent contact with and possible dam-age to the chimney.
Install firestop spacers at each ceiling level.
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.
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.

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 15. 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.
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.
To install the “S” 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.

CHIMNEY OFFSET INSTALLATION

NOTE: If you intend to have a total ﬁreplace installation of more that 30 feet you must use a chimney support at or below 30 feet to support the weight of additional chimney pipe. If it is impossible to nail the chimney support to the load bearing framing of the building at the 30 foot level, the chimney support may be installed at a lower level if the height of the chimney above the support does not exceed 30 feet. The effective height of the chimney support is 16³⁄₄”. Chimney supports must be installed at 30 foot intervals. 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.

Elbow Installation

NOTE: If triple wall elbow is to be placed directly to the top of the ﬁreplace, it will be necessary to bend a tab located on each of the four (4) inlet air collar brackets. Bend these tabs over only when using a triple wall elbow to start a chimney run. The tabs may be easily bent with your ﬁngers or pliers. Figure 19 The following are important points that should be observed when installing elbows on the ﬁreplace:

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. Figure 18
Elbows should not be used in any combination that inclines the chimney more than 30 degrees from vertical.
The limitations on the quantity of elbows per chimney are as follows: If the total height of the ﬁreplace and chimney is—16’0” or more — two elbows may be used in the chimney. 21’ – 0” or more — four elbows may be used in the chimney.
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. Figures 20 and 21 illustrate elbow installations.
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 six-foot intervals with support such as metal support straps.
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

Determine the location and amount of offset required, then select the combinations of chimney sections and el-bows required from the offset chart. Refer to.
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.
Nail the support straps to the framing member with a minimum of two 8-penny nails per strap.
Install the sections of pipe between elbows until the proper number of chimney sections have been installed.
Install the second elbow to return the run of the chimney to vertical.
Nail the support straps of the second elbow to a building frame member.
Continue installing the vertical portion of the chimney.

NOTE: If the inclined portion of the chimney passes through a ﬂoor or ceiling, an SF30 ﬁrestop spacer should be installed to provide the ﬁrestop and support required. Be sure proper spacing in maintained between the chimney and combustibles.

Model SC 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 the chimney above the roof, 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.

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 the inlet air duct or the largest diameter pipe in place until Step 3 is completed.
Remove the shingles from around the chimney so that the ﬂashing may be installed, with the upper part of the ﬂash-ing under the shingles.
Set the ﬂashing on the roof 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. Figure 23
Snap the last section of inlet air duct in place and slide the ﬂashing over the chimney. Adjust the chimney to ensure that the proper minimum clearances are maintained.
Nail the flashing securely in place with eight nails.
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.
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.
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.
Install the chimney cap by placing the cap into matching parts of the last chimney section. Push down until the brackets on the bottom of the chimney cap sit on the chimney pipe. 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.
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.

OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS

NOTE: The use of outside air for combustion is optional unless required by building codes. It is only necessary to supply outside combustion air to one side of the fireplace. Use the Model OAC4 combustion air kit.

Outside Combustion Air Recommendations

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 Figure 24 for methods of installing the outside air for combustion assemblies.
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.
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.
Combustion air can be drawn form the crawl space under a house when an adequate supply of air is provided by open ventilation.
Do not take combustion air from attic space or garage space.

COMBUSTION AIR ASSEMBLY

Model OAC4 Combustion Air Assembly

Remove the cover cap from the 4” outlet opening location on the left or right outside surface of the fireplace. DO NOT REMOVE THE COVER IF THE OUTSIDE AIR WILL NOT BE CONNECTED.
Fasten the 4” starting collar over the hole on the left or right side of the fireplace with the four (4) sheet metal screws provided. Figure 24
Cut a 6” diameter opening for model OAC4 in the outside wall covering where the model OAC4 outside grille is to be located. Figure 26
Select and cut a piece of duct of sufficient length to attach to the fireplace and protrude at least 3” beyond the face of the wall to which the OAC4 inlet air box assembly 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.
If the duct is the insulated type, push the insulation back from one end of the duct approximately 2”. Figure 27
Slip the exposed end of the duct over the flange tube of the fireplace.
Place the duct clamp around the exposed end of the aluminum duct.
Slip the band through the housing, then pull the band tight around the duct.
Snap the band locking screw down and tighten it with a screwdriver or nut driver. Figure 27
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” up to prevent rain from entering the assembly. Be sure the 6” diameter opening around the air duct is sealed with insulating material to prevent cold air from entering through the wall. If it is necessary to splice the duct, a model 403 duct connector should be installed as described in Figure 26.

Combustion Air Assy. Model OAC4 Installation of the Model 403 Duct Connector

Push the insulation back approximately 2” from the end of each duct.
Slip each duct over the duct connector until an equal length of the connector extends into each duct.
Place a duct clamp over the end of each duct and tighten it down snugly.
Push the insulation back into place and over the duct clamp.

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 monox-ide 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:

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.”
WARNING: This ﬁreplace has not been tested with an unvented gas log set. To reduce risk of ﬁre or injury, do not install an unvented gas log set into ﬁreplace. The installer of the ﬁreplace and gas appliance must describe the operation of the ﬁreplace and ap-pliance to the people who will be operating them and leave all instruction manuals with the operator of the appliance.
An approved gas shut off valve must be located outside the ﬁreplace in an area accessible to the users of the ﬁreplace.
All gas piping and ﬁtting must be either steel or malleable iron.
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.
The gas appliance and all connecting gas piping should only be installed by a licensed gas appliance installer. Refer to Page 14, Figure 11 for the gas line opening dimensions on the ﬁreplace.

The following instructions only apply to passing the gas line through the ﬁreplace wall. Follow the in-structions provided by the appliance for the gas line, testing and adjusting it.

Remove the side brick form the ﬁreplace and locate the dimple “B” referred to by Figure 29.
Tap out a round hole in the brick liner with a hammer by tapping lightly on the recessed area.
Remove the two screws that hold the cover plate on the jacket wrap and discard the cover plate.
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.
Install the gas pipe through the tube between the ﬁrebox and jacket.
Attach the gas appliance to the gas pipe according to the instructions provided with the gas appliances.
Pack the insulation removed in Step 4 around the pipe to prevent air ﬂowing through the tube either into or out of the ﬁrebox.
Be sure the gas is turned off at the appliance, then turn the gas on at the cut-off valve and test the gas line connections for leaks with soapy water solution or a liquid leak detector. DO NOT USE A MATCH OR OTHER FLAME SOURCE TO CHECK FOR GAS LEAKS. If a gas leak is detected, turn the gas off immediately and ﬁx the leak.
Proceed with installation and adjustment of the gas appliance as directed by the instructions provided with the gas appliance. If a gas leak is detected, turn the gas off immediately and ﬁx the leak.

TRIM INSTALLATION
The face of your ﬁreplace may be left exposed or trimmed with any noncombustible material such as brick, stone or marble. Figure 30. If a noncombustible 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.

CAUTION: Do not allow any trim materials to extend closer than 3/8” to the vertical edges of the ﬁrebox opening if you plan to equip the ﬁreplace with glass doors. Wall ties should be fastened to the face of the replaced 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 noncombustible caulk or trim materials to prevent cold air leakage around the ﬁreplace.

CAUTION: No trim should block or restrict in any way the ﬂow of air into the air inlets in the face of the ﬁreplace. Figures 30 and 31 Be sure to provide the required ﬂoor protection as described in a preceding section of this manual. Page 13, Figure 10 Combustible mantels and trim must be installed in accordance with the National Fire Protection Association – ANSI NFPA 211 Standard – Section 7-2.3.3.

Glass Door Installation
This ﬁreplace has been tested and listed for use with Model MGD36B or MGD36PB glass doors. For installation of the Model MGD36B or MGD36PB glass doors, refer to the instructions provided with the doors.

Installation of Noncombustible Facing Materials to the Front Face of the Fireplace

NOTE: On B36LA or B36RA Models, noncombustible facing materials may be installed to the top of the ﬁreplace opening. This facing material must be secured and sealed to the face of the ﬁreplace. Failure to properly secure and seal noncombustible facing material to the ﬁreplace can cause a possible ﬁre hazard and will void the warranty.

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 the section titled “Operation Guide-lines”.)

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 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 a 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 FIRE-PLACE. KEEP ALL SUCH LIQUIDS 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. 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.

Species| Density| Heat Value| Species| Density| Heat Value
---|---|---|---|---|---
Dogwood| .70-.79| 100-107| Ash| .57-.61| 81-82
Hickory| .70-.74| 100| Southern Pine| .51-.60| 73-81
Oak| .60-.73| 86-99| Elm| .50-.59| 71-80
Black Locust| .69-.70| 95-98| Cherry| .50-.52| 70
Beech| .64-.66| 89-91| Douglas Fir| .45-.51| 64-69
Hard Maple| .58-.65| 83-88| Spruce| .41-.44| 59
Birch| .55-.64| 79-86| Redwood| .33-.40| 47-54
Apple| .58-.62| 83-84| White Pine| .35-.37| 50

A Few Words Of Caution
Beware of burning certain materials 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 the chimney draft occur, help start the 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 upwind side of the house that is far enough away from 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 & SAFETY

Fuel Storage
Wood can be dried sufﬁciently for burning within a few weeks if protected from 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, how-ever, 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 parti-cles 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. MHSC does not recommend chemical cleaners because some may contain elements that corrode the metal parts of the chimney or ﬁreplace.

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 ab-sorption 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.
