Step 10: Burner Test And Adjustment - Thermador PRD304GHC Installation Manual

Step 10: 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.
NOTICE:
All oven knobs and selectors must be set to OFF before
powering up the range. To prevent unintended operation at
power up, please set all oven knobs to OFF. To ensure
customer safety in the event of power failure, the unit will
display an error message upon reinstatement of power
unless all oven knobs are set to OFF. Set all oven knobs to
OFF and reset the breaker to clear the message.
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 33 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: Simmer 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.
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.
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
