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 gas shut-off valve to the open position.

Test Rangetop Burners

Test Burner Ignition. Select a rangetop burner knob. Push down 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 (4) seconds.

Test Flame: High Setting. Turn burner on to HI. See Figure 29 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 travels completely around the burner. This is known as “carry over.” 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®.

Four rangetop burners, (2) on the left side and (2) on the right, feature the XLO® setting that causes the flame to

cycle on and off when the knob is set to the XLO® range. This is normal operation.

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.

Repeat these Ignition and Flame Test procedures 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.
