Step 4: broiler burner
Remove the screw and pull out the burner from
its support.
ATTENTION: pay extra attention to avoid damage
to the igniter and thermocouple.
Unscrew the nozzle located inside the gas fi tting
using a 7 mm [socket wrench].
Replace the nozzle as table number 1.
Step 5: visual checks
Oven
Before reinstalling the bottom panel, the following
visual check must be performed to ensure that the
conversion has been carried out properly and wi-
thout damage to other components of the range.
Verify that the fl ame of the oven/broiler burner be
completely blue and with regular aspect as shown
below.
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
20
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 6: 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 range 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.
