Converting from Natural Gas to LP Gas
Converting the Burner Orifice Spuds
1. Remove the grates and burner caps.
2. Remove venture tube or burner base by removing 2
screws.
3. Trim a small piece of masking tape to the size of a
dime and place it over the end of a 5/16" or a 9/32"
(7mm) nut driver.
4. Firmly press the nut driver over the orifice spud and
loosen spud by turning counterclockwise. Carefully lift
the nut driver out of the burner throat. Orifice spud
should be captured in the recess. Repeat this step
for each burner.
5. Locate the LP orifice spud packet taped to the
underside of the burner box. The spuds have small
numbers stamped on the side. This number codes
the orifice diameter and its correct burner location.
NOTE: See chart and graphics below for location of
components.
6. With the masking tape still in place in the recess of
the nut driver, press an LP orifice spud into the
recess so that it is snugly captured.
7. Carefully install the orifice spud in the appropriate
burner throat by turning clockwise to tighten.
8. Tighten to a torque of orifice 15 to 20 inch-lbs.
9. Replace burner base. Tighten screws to 25-30 inch-
lbs.
10. Repeat steps 2 through 9 for each burner.
11. Replace burner caps and grates.
12. Save orifices removed from appliance for future use.
