To Reinstall the Oven Door: 1. Hold door on both sides. Insert hinges into hinge slots. The door will be about halfway open. It may be necessary to press firmly inward on the lower portion of the door, using a rocking motion to fully seat the door's hinges. 2. Open door all the way to expose hinge clips. Push hinge clips away from you (toward the oven) until they meet the hinge. 3. Close and open the door slowly to test the installation. It should open and close smoothly and be straight, not crooked. Yellow Flames: Further Adjustment is required. Yellow Tips on Outer Cones: Normal for LP Gas Soft Blue Flames: Normal for Natural Gas Photo C: Hinge removed from oven Step 9: Burner Test and Adjustment Install any loose components, such as burner caps and grates, that may have been removed earlier. Be certain that burner caps seat properly into the burner bases. Before testing operation of the appliance, verify that the unit and the gas supply have been carefully checked for leaks and that the unit has been connected to the electrical power supply. Turn the manual gas shut-off valve to the open position. If the flame is completely or mostly yellow, verify that the regulator is set for the correct fuel. After adjustment, retest. Some orange-colored streaking is normal during the initial start-up. Allow unit to operate 4-5 minutes and re-evaluate before making adjustments. Figure 17: Flame Characteristics If any of the rangetop burners continue to burn mostly or completely yellow, verify that the burner cap is positioned properly on the burner base, then retest. If flame characteristics do not improve, call Thermador. Test Flame: Low Setting. Turn burner on to SIM. Verify that the flame completely surrounds the burner. There should be a flame at each burner port and there should be no air gap between the flame and the burner. If any burners do not carry over, call Thermador. The two rangetop burners on the left side feature XLO, causing the flame to cycle on and off when the knob is set to the XLO range. This is normal operation. Repeat the Ignition and Flame Test procedures, described above for each rangetop burner. Test Rangetop Burners When Flame is Properly Adjusted: Test Burner Ignition. Select a rangetop burner knob. Push in and turn counterclockwise to HI. The ignitor/spark module will produce a clicking sound. Once the air has been purged from the supply lines, the burner should light within four (4) seconds. Test Flame: High Setting. Turn burner on to HI. See Figure 17 for appropriate flame characteristics. There should be a flame at each burner port. There should be no air gap between the flame and burner port. Call Thermador if: 1. Any of the burners do not light. 2. Any of the burners continue to burn yellow. English 18
