STR36 Designer Woodburning Fireplaces Planning Information Preplanning an installation is very important to ensure safety and to save time and money. An installer must predetermine where a fireplace will be set and how the chimney system will be run. NOTE: The STR36 model uses MHSC SK8 (2-wall) chimney systems. Mounting the Fireplace A fireplace may only be mounted on the following surfaces: 1. A flat combustible surface. 2. A raised wooden platform. 3.
STR36 Designer Woodburning Fireplaces Installation Chimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 20' (6 m) above the hearth. Chimney supports are required if the vertical height exceeds 20' (6 m). Locate chimney supports at ceiling holes or other structural framing at 20' (6 m) heights. Spacing between chimney supports must not exceed 20' (6 m). Use Chimney Support Model SKCS8 for SK8 chimney.
STR36 Designer Woodburning Fireplaces Chimney Set-up Framing Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace. Frame fireplace with 2 x 4 lumber or heavier materials. Refer to framing dimensions in Figures 1, 2, 3 or 4 for basic fireplace specifications. Headers and support studs must be turned on end as illustrated on Page 5, Figure 4.
STR36 Designer Woodburning Fireplaces Actual Centerpoint Chimney Centerline Framing the Ceiling Hole 2056O” (521 mm) Frame the ceiling chimney hole as shown in Figure 12. It is good practice to use framing lumber that is the same size as the ceiling joists; this is a requirement at attic level.
STR36 Designer Woodburning Fireplaces Positioning, Safety Strips, Securing the Fireplace Slide fireplace into position. Lift the fireplace front slightly and slide the metal safety strips under front bottom edge about 1¹⁄₂" (38 mm), allowing the remainder to extend in front of firebox. Overlap strips at least 1/2" (13 mm) to provide a positive joint. (Flat safety strips are packed with fireplace.) (Fig.
STR36 Designer Woodburning Fireplaces Installing the Chimney System Pipe Section Start by attaching the first chimney section to the collar on top of the fireplace. Pipe Rim UP Install the pipe as pictured in Figure 16. When you get a good lock, you will hear the pipe clearly snap together. Once sections are snap-locked in place, it is extremely difficult to get them apart. Make sure the pipe is firmly snapped and locked together as each pipe section is mounted.
STR36 Designer Woodburning Fireplaces Firestop spacers are not available for nor are they required on vertical walls. Consider this dimension when determining how many straight chimney sections are needed. DO NOT put any sealant around the area where the outer pipe slides through the firestop spacer. If you seal this area, it may cause a fire hazard. Note: Chimney supports are generally used in long runs in a chase installation. A chimney support cannot be mounted directly to the fireplace.
STR36 Designer Woodburning Fireplaces Install Remainder of Chimney Sections Air Space Clearances Since you have already preplanned the height of your termination according to the Ten Foot Rule, continue to install pipe to the predetermined height. Check the chimney top installation instructions for details on how high above the roof top the chimney sections (all pipes) should extend. Combustible framing material MUST NOT penetrate AIR SPACE (shaded areas).

CHIMNEY OFFSET INSTALLATION 1. Extend the regular chimney sections until the top of the chimney is 4” 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.
CHIMNEY CAP CHASE INSTALLATION SSTB11 Woodburning Fireplace The preinstalled chimney sections should be no more than 13” 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” below the top of the chase. 2.
OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS SSTB11 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.
OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS SSTB11 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 1, 24, and 25 for methods of installing the outside air for combustion assemblies. 2.
COMBUSTION AIR ASSEMBLY SSTB11 Woodburning Fireplace 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 SSTB11 Woodburning Fireplace 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.
GAS APPLIANCE INSTALLATION Figure 29 SSTB11 Woodburning Fireplace Gas Line Plumbing Detail Outer Fireplace Wrap Side Brick Inner Fireplace Wrap Side Brick 24” Max. Fireplace Firebrick Hearth Brick Gas Line Access Tube CAUTION: When using a gas appliance, the fireplace damper must be set in fully open position.
TRIM INSTALLATION SSTB11 Woodburning Fireplace Applying Decorative Trim To The Fireplace 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.
FIREPLACE OPERATION SSTB11 Woodburning Fireplace 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”.) 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.
FIREPLACE OPERATION SSTB11 Woodburning Fireplace 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.
MAINTENANCE & 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.
SSTB11 Woodburning Fireplace 4. Do trim the face of the fireplace only with noncombustible materials. 5. Do attach the noncombustible face trim material firmly to the face of the fireplace. 6. Do block in or fasten the fireplace to prevent the possibility of the fireplace shifting out of position. 7. Do enclose the chimney where it passes through living spaces or spaces accessible for storage purposes to prevent contact with and possible damage to the chimney. 8.

(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.
MPL11 Woodburning Fireplace 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.
MAINTENANCE & SAFETY MPL11 Woodburning Fireplace 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.
MPL11 Woodburning Fireplace MAINTENANCE & 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.
