PAGE 5
Operation Guidelines 5 SB38 / SB44 Series Woodburning Fireplace When an 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.

Fireplace Location SB38 / SB44 Series Woodburning Fireplace 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.

Installation Preparation SB38 / SB44 Series Woodburning Fireplace 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. Figure 11.
PAGE 12
SB38 / SB44 Series Woodburning Fireplace Installation Preparation Single Story Installation with Attic Space Insulating Fireplace Enclosure for Cold Climates Chimney Cap If you live in a cold climate, it is not required but highly recommended that you insulate the fireplace enclosure to eliminate cold air penetration as much as possible. Flue Outlet Height Storm Collar 3’ Min. or 2’ Above any Point within 10’ Insulate base of fireplace with a noncombustible insulation rated for a minimum of 300° F.
PAGE 13
SB38 / SB44 Series Woodburning 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 13, an H2066 hearth extension kit or a locally constructed equivalent to the H2066.
PAGE 14
Floor Protection SB38 / SB44 Series Woodburning Fireplace 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 (.
PAGE 15
MANTEL CLEARANCE SB38 / SB44 Series Woodburning Fireplace Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 18" (457 mm) from the top of the fireplace opening. Do not install a mantel face plate less than 6" (159 mm) from top of fireplace opening. Figure 18. If a combustible material is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace opening to bottom of mantel shelf.

Chimney Offset Installation SB38 / SB44 Series Woodburning Fireplace 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.

SB38 / SB44 Series Woodburning Fireplace Chimney Cap Installation 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.
PAGE 25
SB38 / SB44 Series Woodburning Fireplace 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.
PAGE 26
Outside Combustion Air Precautions & Recommendations SB38 / SB44 Series Woodburning Fireplace 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 AK4 combustion air kit.
PAGE 27
Outside Combustion Air Precautions & Recommendations SB38 / SB44 Series Woodburning Fireplace 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 3, 4, 31 and 32 for methods of installing the outside air for combustion assemblies. 2.
PAGE 28
SB38 / SB44 Series Woodburning Fireplace 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.

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.

SB38 / SB44 Series Woodburning Fireplace 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.
PAGE 33
Fireplace Operation SB38 / SB44 Series Woodburning Fireplace 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.
PAGE 34
SB38 / SB44 Series Woodburning 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.
PAGE 35
Maintenance and Safety SB38 / SB44 Series Woodburning 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 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.
PAGE 36
SB38 / SB44 Series Woodburning Fireplace Maintenance and Safety 17. Do store your fuel supply at a distance equal to or greater than the spacing recommended for combustible materials from the fireplace. 18. Do build fires of moderate intensity in the fireplace for the first three fires to allow materials to adjust and cure before being subjected to the intense heat of a large fire. DON’TS 1. Don’t allow other installations or operation considerations to take priority over safety considerations. 2.
