Natural Gas High Altitude Conversion Instructions
for WB28X29254
For Ranges Operating on Natural Gas at Elevations
More than 6,000 Feet Above Sea Level
WARNING
This conversion must be
performed by a qualified installer or gas supplier
in accordance with the manufacturer’s instructions
and all codes and requirements of the authority
having jurisdiction. Failure to follow instructions
could result in serious injury or property damage.
The qualified agency performing this work
assumes responsibility for the conversion.
IMPORTANT: This kit is designed for ranges
equipped for use with Natural Gas. Use only the
specific orifices called out in these instructions.
Additional orifices may be present.

TOOLS YOU NEEDED FOR CONVERSION
1
REMOVE TOP BURNER ORIFICES
The orifice spuds needed
to enable the top burners
to operate correctly at high
altitude are in this kit.
A. Remove the top grates,
burner caps and burner
heads.
B. Using a 7 mm (9/32”) nut
driver, remove the top
burner orifice spuds. These are accessed through
the burner opening in the cooktop.
C. .HHSDOORUL¿FHVWKDWDUHUHPRYHGIRUSRVVLEOH
future use.
3
CHECK SURFACE BURNERS
Push and turn a knob to the LITE position. A clicking
sound indicates proper operation of the ignition system.
When lighting any burner, sparks will appear at all
burners but gas flows from only the one selected. Once
air is purged from the supply line, burner should light
within 4 seconds. After burner lights, rotate the knob out
of the LITE position. Try each burner in succession until
all burners have been checked.
Quality of Flames
Determine the
quality of flames
visually. Normal
burner flames
should look like
(A) or (B).
Long, bright yellow flames are not normal. Normal
flames may show signs of an orange tint when well
heated or signs of flickering orange due to particles in
the gas or air.

INSTALL HIGH ALTITUDE BURNER
ORIFICES
A. Find your model in the table on page 4. Read the
size stamped on each orifice in the kit and determine
its proper location from the table for your model.
Place each orifice on the maintop next to the burner
opening where it belongs. Not all orifices will be used.

INSTALL HIGH ALTITUDE BURNER
ORIFICES (Cont.)
B. Install the orifices from the kit in their correct locations
using a 7mm (9/32”) nut driver. To prevent leakage,
make sure the orifice spuds are securely screwed
into the gas supply tube. Check the LO flame setting
of cooktop burners by first turning all burners to a
MEDIUM setting. With the other burners operating,
turn the burner to be checked to its LO setting and
observe the flame. If the flame is unstable or goes out
while opening or closing the oven door, refer to the
Propane Conversion Instructions attached to the back
of your range for how to adjust the low flame setting.
Repeat for all burners.
C. If your model has a Dual Broil burner (a burner with
two tubes in the top of the oven), follow steps 1
through 5 below to replace the broil burner orifices.
If not, go to Step D.
1. Remove the oven door for easy access to
the broil burner. See Owner’s Manual for
instructions.
2. Remove the two ¼” hex screws securing the
broil burner and slide forward to expose the broil
orifices on the rear wall. Allow burner to hang
down clear of the broil orifices.
3. Apply a ½” open-end wrench or socket to the
hex base of an orifice. Loosen the orifices by
turning counter-clockwise and remove.
4. Find the two large orifice hoods in the kit.
Install them on the two broil fittings and tighten
until snug.
5. Replace the broil burner over the orifices and
replace screws securing the burner in place.
Replace oven door.
D. Place the old orifice spuds in the plastic bag along
with these instructions and save for possible
future use.
