STEP 7: BACKGUARD INSTALLATION
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.
CAUTION
Thermador recommends that
burner adjustments be made by
a qualified technician at the
time of installation. Extreme
care should be used when
adjustments are made after
installation. Improper or lack of
adjustments may void your
warranty.
