Figure 19: Removing
valve screw.
e) Flip the screw (refer to Figure 20).
f) Using the Allen wrench as shown
in Figure 19, rotate the screw
clockwise until a torque of 9 inch lbs.
WARNING! Do not over tighten the
screw. It is recommended that you
grip the wrench by the short side.
g) Verify that if the conversion is from
NG to LPG, the screw must be re-
assembled with the red o-ring visible

by hand shown in Figure 18.
c) Insert a 5 /
32
” or 4 mm Allen wrench into the hexagonal

clockwise until it is free and extract it.
d) Check that the screw is clean and if necessary remove
dirt.
