Setting STAR
screws
A flat-head screwdriver with an
1/8" [3.0 mm] wide, .020"
[0.50 mm] thickness tip
(included) is used to adjust the
valve screws.
To set the burner valve screws

pulling knob straight out, away from the control panel.
2. Remove the bezel-mounting
screw located to the right of
the valve stem, using a T-20
torx screwdriver.

3. Insert a 1/8'' flat-
blade screwdriver
into the hole of the
bezel mounting
screw. Access to the
valve screws through
clearance hole in the
spark module. You
should feel the
engagement of the
screwdriver and the
valve screw.
4. Adjust the valve screw by turning the valve screw
th
about an 1/8 turn. Turn the screw clockwise to
reduce simmer flame size. Turn the screw counter-
clockwise to make the simmer flame larger. Adjust the
valve screw as little as required to reach satisfactory
simmer results. Due to normal fluctuations in gas
pressure, over-adjustment of valve screw may affect
flame stability.
5. Perform a gas leak test of each orifice and associated
supply tube fittings. See "Checking for gas leaks" on
page 16. Leak-checking should occur after the orifice
conversion is complete, and before the burner is
reassembled and tested.
