Variation: Standard Flat Wall

These illustrations refer to an installation into a standard flat wall and facade on a Mountain Home (RFG-IR) oven. Many details are applicable to all of our WS-MH ovens; some apply to WS-MH-RFG-IR ovens only.

Keep in mind as you read through this tutorial that we make Facade Extensions that can make much of this installation process easier. Be sure to view our Facade Extension page for details.

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 standard WS-MH-5-RFG-IR (Mt. Adams) oven. For more details on how the oven arrives from the factory, please visit our Unloading & Moving page.

Mount the Service Panel, Toe Kick and optional Mantle per the instructions in the installation manual.Please note the location of the Toe Kick, it ships unattached and is installed at a small offset from the Service Panel to maintain room for combustion air. See the Airflow Detail. Also note the Venting Requirements.

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 adove the oven doorway must be completely non-combustible (i.e. cement board and metal studs). See Step 4.

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 Service Panel can still be removed for oven service. For more info, see the Panel Detail.

Note that the control box is mounted in the Service Panel where it is convenient for the chef to operate. (The control box can be remounted in a different position, but you will need to specify at the time of order so we can plug the service panel hole and ship the controller with a longer lead).

Step 3. Custom Fabrication

Shown in Figure 3.1 in red is a customer-fabricated throat extension for the unique requirements of the installation architecture.

(This piece is required if a Facade Extension, such as those shown in Figures 3.2-3.4, are not purchased from Wood Stone.)

On top is the doorway surround, which should be stainless steel for sanitary reasons. It should fit snugly and be welded to the inside lip of the oven doorway to lock it in position without any gaps. Note: the custom fabricated doorway span must not block or obstruct ventilation through the flue (see Weld Detail).

The service panel surround below can be sheet metal as well, but need not be stainless if is to be facaded. Both however, must be of non-combustible material (since they touch the oven). If the sevice panel is facaded it must allow for the same amount of air intake area (perforation) as is supplied on the factory-provided service panel. The service panel MUST be removable and provide the same area of service access as the panel supplied with the oven. All service and maintenace to the oven occur from beneath the oven. The service panel is the ONLY access to this area.

Step 4. Non-Combustibles

Yellow is the non-combustible cement board. This is required directly over the oven doorway and 6″ on either side of the doorway.

Non-combustible material is also required anywhere the facade 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.

Usually a cement board is used for this application. Brand names of appropriate underlayment include Wonderboard and DUROCK. (Drywall is considered a combustible and should not be used).

Step 5. Adding Drywall

Shown in the lighter yellow 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.

Step 6. Finishing

The facade wall can be finished with any decorative material that can be easily affixed to the wall surface such as tile, stucco, sheet metal, brick etc.

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.
