Step 6: Backguard Installation
A Low Back backguard must be installed when there is less
than a 12" clearance between combustible materials and
back edge of cooktop. (See Figure 1 and Figure 5.) For
island installations and other installations with over 12"
clearance, an optional stainless
steel trim channel is
available to cover the backguard mounting flanges. Attach
the backguard before sliding the appliance into the final
installed position. Follow Steps A through C below:
1. Slide backguard over the two flanges on the rear of the
appliance. Fasten the front and back with the two
screws (see A, Figure 11) provided.
2. Fasten the top of the backguard to the wall with two
screws through the backguard. (See B, Figure 11.)
3. Place the backguard cap on top and fasten using the
two counter-sink screws provided. (See C, Figure 11.)
Step 7: 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.
Test Cooktop Burners
Test Burner Ignition. Select a cooktop 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 12 for appropriate flame characteristics. If any of the
cooktop burners continue to burn mostly or completely
yellow, verify that the burner cap is positioned properly on
the burner base, then re-test. If flame characteristics do not
improve, call Thermador.
Test Flame: Low Setting. Turn burner on to LO. 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 far left burners 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 cooktop burner.
