ASSEMBLE NEW ORIFICES in
place on the cooktop exactly as
layed out in the orifice package card
as shown in Figure 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 Figure 6
(with a 20 mm socket or an
adjustable wrench). USE LOW
TORQUE.

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 "botto-
med out". USE LOW TORQUE.
e) Replace knobs.
5. TEST TO ENSURE A SUCCESSFUL CONVERSION

manual.
