Step 9: Burner Test And Adjustment; Test Rangetop Burners - Thermador Professional PRO-HARMONY PRD30 Manuel D'installation

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.

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.

Test Rangetop Burners

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.

Yellow Flames:
Further Adjustment is
required.
Yellow Tips on Outer
Cones:
Normal for LP Gas
Soft Blue Flames:
Normal for Natural Gas
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.
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.
When Flame is Properly Adjusted:
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.
