Replacing the Burner Orifices

1. Use a 7 mm or a 9/32" socket with 1/4" nut driver to
reach down through the jet holders and remove the
Natural Gas orifice from the burner's jet holder (see
.
image below)
2. Replace each STAR burner jet orifice with one of the
1.15 mm, LP jet orifices supplied in the kit.
• All of the replacement orifices in the conversion kit
have straight threads (not pipe threads) and do not
require thread sealing compound.
3. Perform a gas leakage test of each orifice and
associated supply tube fittings. See "Check for Gas
Leaks" on page 6.
• Leak-checking should occur after the orifice
conversion is complete, and before the burner is
reassembled and tested.

Reassemble the Cooktop

1. For the single piece ignitor, carefully feed the wires
through the heat shields, if applicable. Ensure that the
ignitor wires do not crimp.
For the two piece ignitor, reinstall the heat shield, if
applicable (wire feed not necessary).
2. For the single piece ignitor, carefully feed the wires
through the spill trays. Ensure that the ignitor wires do
not crimp.
For the two piece ignitor, reinstall the spill trays (wire
feed not necessary).
3. Reinstall the Flush Island Trim with T-20 Torx screws.
4. For the single piece ignitor, carefully feed the ignitor
wires through the burner pedestals.
For the two piece ignitor, reinstall the burner pedestals
(wire feed not necessary).
5. Insert the venturi into the burner pedestals. Secure with
the black T-30 Torx screws, starting both before fully
securing either screw. Ensure that the venturi does not
'lock down'. The venturi should be pulled out smoothly
and easily once the pedestals have been secured.
