3.4 Testing Burner Ignition
Ignition Hazard
Do not touch the burners when the igniters are sparking.
■ Push burner control knob in, and turn counter-clockwise to
HI
.
The igniter should produce a clicking sound as it is sparking, and
the burner should light within four seconds.
3.5 Testing the HI Setting
Set the burner knob to
HI
, and observe flame characteristics
(see Figure 6 and Figure 7). If any rangetop burner flame burns
primarily yellow, verify if the burner cap is positioned properly on the
burner base, and then re-test. If flame characteristics do not improve,
call Thermador technical support at (800) 444-9091.
3.6 Testing the SIM Setting
Set the burner knob to
SIM
. Make sure that the flame completely
surrounds the burner. There should be a flame at each burner port
and there should not be an air gap between the flame and the burner.
If the flame does not extend completely around any of the burners,
call Thermador technical support at (800) 444-9091.
3.7 Testing the XLO Setting
The left-front and left-back burners have the XLO feature. Set the
burner knob to
XLO
and observe if the flame cycles correctly - on for
approximately 8 seconds, and then off for 52 seconds of each minute.
3.8 Manually Setting Burner Valves - Natural Gas Units
When using natural gas, although pre-adjusted, if you need to set the
XLO valves and standard valves for the lowest possible flame setting,
then manually adjust the bypass screws on all valves.
For manually setting the valves when using LP gas, refer to
QuickFinder for the LP Gas Conversion Instructions PALPKITHC
(649832).
3.8.1
Tools Needed
■ T-20 driver
■ A precision screwdriver with high-strength blade, with 1/8"
[3.0mm] wide, .020" [0.50mm] thickness tip should be used to
reposition the bypass screws for minimum flow settings on manual
valves.
3.8.2
Adjusting the Bypass Screws
1. Remove knobs from valve stems by slowly pulling knobs straight
out, away from control panel.
2. Remove and retain the bezel mounting screw located to the right
of the valve stem, using a T-20 driver (see Figure 8).
3. To engage the valve screw, insert the precision screwdriver with
1/8” blade into the same hole in the bezel that was created by the
removal of the mounting screw (see Figure 9).
4. Turn the valve screw clockwise just until "bottom out" position is
reached. DO NOT over-tighten the valve screw (see Figure 9).
NOTE:
The two valves for XLO operation (farthest left on control
panel) must be in the OFF position for proper access to the valve
screws through clearance holes in the XLO potentiometers.
