CAUTION Thermador recommends that burner adjustments be made by a qualified technician at the time of installation. Extreme care should be used when adjustments arc made after installation. Improper or lack of adjustments may void your

warranty.

STEP 8: 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 alignment slots in 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 electric power supply. Turn the manual gas shut-off valve to the open position. Check operation of the sealed gas burners and grill by pushing and turning each knob counterclockwise to "HI". The burner igniters will click until the flame ignites. The two far left sealed burners feature XLO®, causing the flame to cycle on and off when the knob is set to the XLO range. This is normal operation.

Burner flames should be blue and stable with no yellow tips, excessive noise, or lifting of the flame from the burner. If any of these conditions exist, check that the air shutter (grill, griddle and gas oven only) or burner ports are not blocked or clogged. Remove any blockages that exist.

If the flame is too yellow, indicating insufficient air, adjust the shutter counterclockwise to increase air inlet (grill, griddle and gas oven only).

The sealed top burner flames should be approximately 1" to 1-1/4" high. The griddle, grill, gas oven and infrared broiler burner flames should be as shown in Fig. 23).

NOTE: No air shutter or low flame adjustment is necessary or possible with the sealed top burners.
