CONVERTING APPLIANCE FOR USE
WITH LP GAS
WARNING
Propane conversion is to be performed by a JENN-AIR AUTHORIZED
SERVICER (or other qualified agency) 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 this conversion.
WARNING
Electrical power and gas must be turned off prior to
conversion.
This appliance was adjusted at the factory for use with natural gas. To
convert it for use with LP gas (propane or butane), each of the following
modifications must be performed:
A. Replace all orifice spuds
Step 1: Remove the grates and burner heads.
Step 2: Remove aluminum venturi tube.
Step 3: Trim a small piece of masking tape to the size of a dime and
affix it over the end of a 5/16² nut driver.
Step 4: Firmly press the nut driver over the orifice spud (figure 7) and
loosen spud by turning counterclockwise. Carefully lift nut
driver out of burner throat. Orifice spud should be captured in
the recess. Repeat this step for each burner.
REMOVAL OF ORIFICE SPUD
Step 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. The following illustrations show correct LP
orifice spud location for 4 burner and 6 burner models,
respectively.

Step 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.
Step 7: Carefully install the orifice spud in the appropriate burner throat
by turning clockwise to tighten. Tighten to a torque of 15 to 20
inch-lbs.
Step 8: Replace cylindrical aluminum venturi tubes. Replace burner
heads and grates. Index each grate to its burner pan.
Step 9: Save the orifices removed from the appliance for future use.
