Copies may be obtained from The American Gas Association, Inc., 1515 Wilson Blvd., Arlington, VA 22209. 3. National Electrical Code ANSI/NFPA-70 (latest edition). Copies may be obtained from The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269. In Canada, refer to: 1. Local codes. 2.
Bumper Bars (Convection Oven Ranges Only) CAUTION: Failure to install bumper bars may cause motor damage and may void the warranty. Remove existing #10 screws. Position bumper bars (supplied) as shown. Replace #10 screws and secure bumper bars (Fig. 2). REAR VIEW OF RANGE NOTES: 1. Bumper bars required for all Convection Oven Ranges. 2. Restraining device required for all ranges with casters. 3. Restraining device not supplied by unit manufacturer.
Fig. 3 Fig. 4 3. Assemble the required components as shown in Fig's. 3 and 4. 4. Lift the assembly up, sliding the channels into the space provided at the rear of the range (this may require 2 people). 5. It may be necessary to pull the heat shield bottom out slightly in order to clear the oven flue box area. Be sure the backsplash is resting evenly and the channel holes are lining up with the holes provided in the rightand left-hand body side (Fig's. 5 & 6). Fig. 6 Fig.
Fig. 7 6. Install eight #10 sheet metal screws (4 to each channel leg) (Fig. 7). 7. From the front, install four 1/4-20 x 2 5/16" long machine screws and secure bolts with locknuts. Do not tighten the screws all the way down. Leave about 1/4" of play in each screw (Fig. 8). 8. Lift the shelf up and slide the shelf into position over the screw heads (Fig. 9). 9. Tighten the four screws to secure the shelf. Fig. 8 Fig.
LEVELING Check the leveling of the range. Place a carpenter's level inside the oven cavity across the oven rack(s). Level front-to-back and side-to-side. To adjust the leveling, tilt the range to one side and, using channel locks, unscrew the adjustable leg insert as required. Repeat this procedure as necessary for each leg. Casters for this range are of the non-adjustable type. Therefore, the floor must be level. If floor surface is not level, the range will experience cooking problems.
Fig. 10 WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME. After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air. TESTING THE GAS SUPPLY SYSTEM When gas supply pressure exceeds 1/2 psig (3.45 kPa), the range and its individual shutoff valve must be disconnected from the gas supply piping system. When gas supply pressure is 1/2 psig (3.
ELECTRICAL CONNECTIONS (CONVECTION OVEN MODEL ONLY) WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.

To save on gas consumption, do not operate oven at maximum heat when it is not necessary. Turn thermostat down to 250°F or OFF when oven is not in use or during idle cooking periods.
RACK ARRANGEMENT - CONVECTION OVEN Capacity The convection oven is supplied with three oven racks. The oven cavity provides a five-position rack support for maximum cooking flexibility. The following arrangements are the most commonly recommended. The rack positions are numerically sequenced starting at the bottom. Arrangement #1 Three racks in Positions 1, 3 and 5 for oven broiling, baking cookies, or reconstitution of frozen meals.

DO NOT use scouring powder. It is extremely difficult to remove completely, and accumulations can build up that will damage the oven. Painted surfaces may be cleaned using a soft cloth and mild detergent solution. RANGES Daily: Remove racks and clean in a sink.
CONVECTION OVENS ONLY Keep the convection tube opening (Fig. 20) clear from blockage. If usage of aluminum foil is a common practice during the operation of this oven, be sure to periodically check the convection tube for foil particles. CONVECTION TUBE OPENING PL-40672-1 Fig. 20 Clean the convection tube with standard oven cleaner at least once a week. Be sure to thoroughly clean all cleansing solution off the tube before using oven again.
