Step 9 Burner Test And Adjustment - Thermador PRL366EH Installation Instructions 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 Hame: High Setting. Turn burner on to HI. See
Figure 9 for appropriate flame characteristics.
If any of the rangetop burner 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 Hame: 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
ThermadorO.
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, de-
scribed above for each rangetop burner and the grill
burner (if so equipped).
F_G. 9 F_ame Characteristics
Yellow Haines:
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 mSPROPERLY ADJUSTED:
There shouM be a flame at each burner port.
There should be no air gap between the flame
and burner port.
The gas grill uses a tube-style burner that has an air
shutter which allows adjustment to the amount of
primary air inside the burner tube.
Air shutters of tube-style burners are pre-adjusted
at the factory, and usually do not require readjust-
ment except under rare conditions such as installa-
tion at high altitude.
If grill burner/flame adjustment is required, go to the
procedure: "Flame Adjustment (if necessary)".
