Converting from Natural Gas to L.P. Gas
!WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power to oven before servicing, unless
testing requires power.

Converting from Natural Gas to LP Gas
Converting the Burner Orifice Spuds
1. Remove the grates and burner caps.
2. Remove securing burner base to cooktop surface.
3. Remove the Natural Gas burner spud using a
9/32" (7 mm) nut driver. Save spud to reconvert if
necessary in the future.
4. Install the LP/Propane spud (included in literature
package).
NOTE: See Specifications Chart on first page for
location of components.
5. Tighten to a torque of orifice 15 to 20 inch-lbs.
6. Tighten burner base screws 25 to 30 inch-lbs.
7. Repeat steps 2 through 4 for each burner.
8. Replace burner caps and grates.
Converting Pressure Regulator for LP/Propane
1. Remove pressure regulator cap using a wrench.
2. Apply sideward finger pressure to remove pin from
cap.
Apply sideways
finger pressure
to remove pin
from cap
3. Apply downward finger pressure at the disc edges to
place pin into the cap.

NAT
4. Place pressure regulator cap on pressure regulator
and tighten.
Low Flame Adjustment
Properly adjusted burner flames are clean and blue with
a distinct inner cone approximately ½ inch long.
1. Remove control knob from valve stem.
2. Carefully remove rubber grommet from cooktop.
3. Locate valve adjustment screw.
4. Insert a slender thin bladed screwdriver into knob
hole and engage blade with slot in adjusting screw.
5. Turnadjustingscrewclockwiseuntiltight(5–7in-lbs.
Max.). Do not over tighten.
6. Replace rubber grommet and control knob.
7. Repeat process for remaining burners.
After adjusting the screw the burner should produce a
stable, steady blue flame of minimum size. The setting
should be checked by turning the knob from high to low
several times without extinguishing the flame.
This operation will automatically provide the proper flame
size at medium setting.
After conversion steps have been completed, check the
appearance of each burner flame at high and low
settings. If the flames appear too large or small, review
each step to verify it was completed correctly.
