Test Oven Burners
Remove the oven bottom cover. Remove the (4) screws
that attach the cover to the bottom of the oven, then lift the
cover and angled baffle plate out to expose the U-shaped
bake burner. The procedure to expose the bake burner in
the small oven of the 48" range is the same.
Test Bake Burner Ignition
To test each oven, set the oven to BAKE at 350°F (177°C).
After a short delay, the burner will ignite. The burner will
stay lit until 350°F (177°C) is reached and then shut off.
From this point forward, the burner will cycle on and off to
maintain the temperature.
Test Bake Burner Flame
While the bake burner is lit inspect the flame. See
Figure 28 on page 25 for proper flame characteristics. If the
flame burns completely or mostly yellow, it is necessary to
adjust the bake burner air shutter, see the Flame
Adjustment procedure in the following section.
Test Broil Ignition
Set cooking mode to BROIL. The broil burners will ignite
after 30-75 seconds.
Note:
The two infrared ceramic broil burners do not have air
shutters, so no adjustment is provided.
Replace oven bottom cover. Slide cover into place and
reattach to bottom of oven cavity.
WARNING
Burner adjustments must be performed by a qualified
technician. Improper adjustments may cause harmful by-
products or void the appliance's warranty.
Flame Adjustment (if necessary):
Tube-style gas burners used in THERMADOR ® appliances
have air shutter systems which are similar to the illustration
in Figure 29, and can be adjusted using the following
method (unless adjustment is not recommended). It is
necessary to remove the burner from the appliance in order
to perform air-shutter adjustments.
• Loosen shutter screw(s) and turn shutter to new
position.
• Adjust the shutter to more-closed position if the flame
is lifting or blowing, or is not carrying over. Adjust the
shutter to more-open position if the flame is too yellow
(Figure 29).
• Retighten the shutter screw(s).
• After adjustment, reinstall the burner and perform
flame evaluation. The air shutter must fit over the
orifice hood for proper operation of the burner.
• Repeat procedure as needed until flame characteristics
are acceptable (see Figure 28 on page 25).

Allow burners to cool before attempting to remove them!
