Natural gas conversion
1.
Complete installation sections A-C (Pages
4-5) before converting cooktop to natural gas.
Check that main gas supply line has been shut
off and the power supply cord is disconnected.
DO NOT REMOVE THE PRESSURE REGULATOR.
2.
Pressure regulator:
Remove storage
drawer and locate pressure regulator at back of
range. Remove plastic cover. Turn cap marked
“L.P.” on front of pressure regulator
counterclockwise with a wrench to remove.
Do
Not disturb or remove the spring beneath the
cap.
Turn the cap over and reinstall cap on
regulator so that the letter “N” is visible. Replace
plastic cover over cap.
5.
Broil burner:
Use 1/2" combination
wrench to loosen orifice hood away from pin
(approximately 2 to 2-1/2 turns). The burner
flame cannot be properly adjusted if this
conversion is not made.
6.
Reinstall the storage drawer. Complete
installation sections D through E, Pages 5-7.
Checking for proper cooktop burner and oven
flame is very important.
YOU MUST ADJUST “LOW” SETTING FOR
EACH COOKTOP BURNER. SEE STEP 16, PAGE 6.
Natural gas flames do not have yellow tips.

The small inner cone should have a very distinct
blue flame 1/4" to 1/2" long. The outer cone is not
as distinct as the inner cone. L.P. gas flames may
have a slightly yellow tip. If the flame is noisy or
blowing, it is getting too much air. If the flame is
soft and lazy, it is not getting enough air.
A brass orifice spud is located in the center of
each burner throat about 2" below the cooktop.
Apply masking tape to the end of a 5/16" nut
driver to fit snugly over the orifice spud. Press
driver down onto the spud of the left front burner
and remove by turning spud counter-clockwise
and lifting it out. Replace the Natural gas spud
with the appropriate L.P. gas spud shown in the
table.
Continue to replace the remaining orifice spuds,
one at a time. Place the Natural gas spuds on the
spud card on the back of the range for future use.
Replace burner caps using both screws, and
burner grates.
