ASSEMBLE NEW ORIFICES in
place on the cooktop exactly as
laid out in the orifice package card
as shown in Figures 5. Place the
new orifices into the socket one at
a time (the tape will keep them in
place), then insert each orifice into
its threaded hole in jet holders. USE
LOW TORQUE.
REPLACE OLD VENTURI NUTS
with new venturi nuts, see Fig. 6
(with a 20 mm socket or an
adjustable wrench). USE LOW
TORQUE.
4. CONVERTING VALVES

The bypass jet on each valve must
be adjusted. Your cooktop may come
with either hollow or solid valve shafts.
Determine the bypass screw location
accordingly. See figure 7.
a) Place all knobs to "Off" position.
b) Remove knobs.
c) Locate hole on cover which is
aligned to bypass screws. See Fig. 8.
d) Insert screwdriver in hole and
turn bypass screw clockwise until
"bottomed out". USE LOW TORQUE.
e) Replace knobs.
5. TEST TO ENSURE A SUCCESSFUL CONVERSION
Check for flame characteristics: flame should be blue with no yellow tip. See "Final Check" section of the Installation
manual.
