Step 9: Burner Test And Adjustment - Thermador PRO-HARMONY PRG30 Installation Manual

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 10 for appropriate 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 far left burners feature XLO, that causes 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.
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.
Figure 10: Flame Characteristics
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.
Test Oven Burners
Remove the oven bottom cover. Remove the 4 screws
on the sides and the 2 screws on the back, then slide the
cover forward while lifting to clear the angled baffle plate
mounted to the bottom of the cover.
Test Bake Burner Ignition
Set the oven to BAKE at 350°F. After 30-75 seconds, the
burner will ignite. The burner will stay lit until 350°F is
reached and then shut off. From this point forward, the
burner will cycle on and off to maintain the temperature.
