Thermador PCG48, PCG36, PCG30 installation manual Cabinet Preparation

Step 2: Cabinet Preparation

1.To ensure professional results, the cabinet and countertop openings should be prepared by a qualified cabinet worker.

2.The clearances shown in Figure 1 are required. The same clearances apply to island installations, except for the overhead cabinets, which must have a space wide enough to accept the island hood.

3.The cooktop is designed to hang from the countertop by its side flanges. The countertop however, must be strong enough to support this cooktop. It may be necessary to add a supporting cleat along each side (see Figure 2) or a 2 x 4 corner brace (see Figure 3 and Figure 4 and Detail A). Another alternative would be to construct a deck to set the cooktop on.

4.The cooktop can be installed in various positions with the front either flush or projecting, depending on the countertop’s depth. (See Figure 5, side view of cooktop; see Figure 3, Figure 4, Figure 6 and Figure 7 for alternate mounting positions.)

5.The gas and electrical supply must be located in an area that is accessible without requiring removal of the cooktop. The appliance electrical power cord and gas pipe connection are located on the left rear underside of the cooktop, as shown in Figure 5 and Figure 9.

6.The maximum depth of over head cabinets installed on either side of the hood is 13".

A 40-inch minimum clearance is required between the cooking surface of the cooktop and the bottom of an unprotected cabinet. A 30-inch distance can be used when the bottom of the wood or metal cabinet is protected by not less than 1/4 inch of a flame retardant material covered with not less than No. 28 MSG sheet steel, 0.015 inch (0.4

mm)thick stainless steel, 0.024 inch (0.6 mm) aluminum, or 0.020inch (0.5 mm) thick copper. Flame retardant materials bear the mark:

UNDERWRITERS LABORATORIES INC. CLASSIFIED MINERAL AND FIBER BOARDS SURFACE BURNING CHARACTERISTICS

followed by the flame spread and smoke ratings. These designations are shown as "FHC (FIame Spread/Smoke Developed)." Materials with "O" flame spread ratings are flame retardant. Local codes may allow other flame spread ratings.

7. When there is less than a 12" horizontal clearance between combustible material and the back edge of the cooktop above the cooking surface, a Thermador Low Backguard must be installed. (See Step 6). When clearance to combustible material is over 12", a Thermador Island Trim may be used. Attach the backguard before sliding the appliance into the final installed position.

8.Establish the centerline of the cooktop’s desired location. It should be the same as the center of the overhead ventilation hood.

9.Cut the openings for the following installations:

•Wall installation, see Figure 3.

•Island installation, see Figure 4.

10.For installation of a 48" cooktop above two side-by-side Thermador Warming Drawers, Model No. WD24, refer to Figure 8. Completing the installation as per Figure 8 will result in the left and right edges of the cooktop being aligned with the left edge of the left-side warming drawer and right edge of the right-side warming drawer. If different alignment is desired, the 1-7/8" horizontal distance between warming drawer cutouts may be varied. However, maintain at least a 1-1/8" distance to avoid interference between the warming drawers. Attach a 90-degree elbow to the gas cooktop inlet pipe. All above-the-countertop clearances must be maintained, as shown in Figure 1.

As defined in the "National Fuel Gas Code" (ANSI Z223.1/NFPA54-current issue).

NOTES:

•If a solid side cabinet wall exists on one or both sides, you will need to notch the front corner of the cabinet to match the countertop notch and to allow clearance for the cooktop front (see Detail A, Figure 3 and Figure 4).

•If a supporting deck is used, the sides or bottom of the cutout may be solid combustible or non-combustible material. If the bottom is solid, provide a 8" by 8" cutout in the left rear corner of the supporting deck. This will provide clearance for the gas inlet and power cord, while also allowing viewing of the product rating label.

•Always keep appliance area clean and free from combustible materials, gasoline and other flammable vapors and liquids.

•Do not obstruct the flow of combustion and ventilation air to the unit.
