These illustrations refer to an installation into a standard flat wall and façade on a WS-MS-5-RFG-IR dual-temperature gas oven. Many details are applicable to all of our Mountain Series (WS-MS) ovens; some apply to WS-MS-RFG-IR ovens only.Keep in mind as you read through this tutorial that in this example we are utilizing Wood Stone manufactured Flat Facade Extensions that are designed to make the installation process easier and cleaner. We make extensions for the doorway and for the lower panel area (in this tutorial instead of the panel we utilize the storage box facade extension). These extensions can come as flat or curved, as well as arched in the doorway. Be sure to view our Facade Extension page for more details on the options. Note: Click on the individual graphics for close up views. Please be patient, some graphics have large file sizes (50-100K).
Step 1. The Base Oven
Figure 1.1 represents a WS-MS-5-RFG-IR oven which shipped with an optional Flat Doorway Facade Extension mounted at the factory. Specs for additional sizes are available in our on-line Product Catalog and CAD Symbols in our CAD Library.
For more details on how the oven arrives from the factory, please visit our Unloading & Moving page.
In figure 1.2 the Storage BoxFacade Extensionis mounted.
It will have been pre-aligned with the Doorway Extension at the factory and then removed for shipping ease. Please note: if a doorway façade extension is ordered, it is recommended that either a Service Panel Extension or Storage Box Extension accompany it.
Our Mountain Series ovens can be vented with a direct connection to a grease rated duct, or vented with a Hood. Please see our Venting page for more details on which is appropriate for your installation. Always submit your venting plans to the appropriate local authorities before proceeding
In this example we assume a hood is required. Mount the Hood to the oven as seen in Figure 1.3 using the mounting flanges (see Mounting Detail).
Step 2. Stud Wall
Here the stud wall is built (in green). Metal studs are recommended. Consideration must be given to the wall framing position to insure the minimum one-inch clearance from the back of the wall surface (sheetrock) to the oven sheet metal (see Offset Detail). Note that all facade materials within 6" of either side of the oven doorway AND above the oven doorway must be completely non-combustible, i.e., cement board and metal studs. It is also recommended that you fabricate a Trim Piece to connect the wall to the top of the oven, thus keeping grease from dripping down from the hood to in-between the oven and facade wall (see Trim Detail).
It is critical that when the hood is mounted and the wall is built there is a minimum of 8" of overhang by the hood in front of the facade for access to the filters. Without this access the hood will be unreachable and thus cannot be cleaned. This can create a very dangerous situation. Adequate clearance is a must (see Filter Removal Detail).
In addition, the studs on either side of the doorway must be far enough apart so that when sheet rock and tile are installed, the Storage BoxFacade Extension can still be removed for oven service.For more info, see the Panel Detail.
Note the control box comes mounted to the leg of the oven when a Storage BoxFacade Extension is ordered but can remounted in a different position.

Step 3. Non-Combustibles
Seen here in yellow is the non-combustible wallboard. This is required above the oven doorway and 6" on either side of the doorway.
Non-combustible material is also required anywhere the façade touches the oven or the mantle. In this illustration, the non-combustible wallboard is used as flashing from the studs to either side of the service panel and contacts the edge of the mantle.
Cement board is used for this application. Brand names of appropriate underlayment include Wonderboard and DUROCK. (Drywall is considered a combustible and must not be used in the area around the doorway).
Step 4. Adding Drywall
Shown in Beige is the drywall applied to the stud wall. This portion does not need to be non-combustible.
For the sake of simplicity of construction, many installers choose to make the entire wall out of the non-combustible cement board mentioned above as to avoid cutting many oddly shaped segments.
Please note here the Airflow Detail. Sufficient combustion air for the oven's burners must come from the front of the same space (room) as the oven doorway.
Step 5. Finishing
The facadewall can be finished with any decorative material that can be easily affixed to the wall surface such as tile, stucco, sheet metal, brick etc. Your local jurisdiction may have regulations regarding cleanability of the wall surface. You may want to discuss this with the appropriate authority having jurisdiction before proceeding.
Note: It is necessary for the proper operation of our ovens that the Radiant Flame Control Knob be fully accessible after all finishing is completed. Please see the Radiant Knob Detail. This knob controls temperature in our gas ovens, if you cannot adjust the knob you cannot adjust the temperature.
