Step 3: visula checks
Surface burners
The burner fl ame color should be blue with no yel-
low on the tips. It is not uncommon to see orange
in the
fl ame color; this indicates the burning of airborne
impurities in the gas and will disappear with use.
With propane (LP) gas, slight yellow tips on the
primary icone are normal.
The
fl ame should burn completely around the bur-
ner cap. If it doesn’t, check that the cap is posi-
tioned
correctly on the base and that the ports are not
blocked.
The
fl ame should be stable with no excessive noi-
se or fl uttering.
After performing all these visual checks, reinstall
the bottom panel of the oven compartment and
proceed to setting the minimum for each burner.
Step 4: minimum fl ame adjustment
WARNING!
These adjustments should be made only for use
of the appliance with natural gas. For use with li-
quid propane gas, the choke screw must be fully
turned in a clockwise direction.
SURFACE BURNERS
Light one burner at a time and set the knob to the
MINIMUM position (small
fl ame).
Remove the knob.
The rangetop is equipped with a safety valve.
Using a small-size slotted screwdriver, locate the
choke valve on the valve body and turn the choke
screw to the right or left until the burner
fl ame is
adjusted to desired minimum.
Make sure that the
fl ame does not go out when
switching quickly from the MAXIMUM to the MINI-
MUM position.
For the gas valve of dual burner the choke valve is
located on the valve body, the A screw adjust the
outer ring, the B screw adjust the inner ring.
