Adjusting the Gas Valves
1.
Turn the control knobs to the lowest setting.
2.
Remove the control knobs from the gas valves and
remove the white ring that is underneath.
A flexible black rubber sealing ring will be visible.
Below the left upper position of that seal, there is a
visible black Star T10 screw, partly hidden by the seal.
Press the rubber seal aside a bit to meet the screw
with a long thin T10 screwdriver. The dual-flame
burner has 2 setting screws.
Never remove the sealing ring.
Sealing rings prevent
liquids and dirt from finding their way into the
appliance and impairing its ability to function properly.
3.
See the following chart for the setting of the gas
valve’s setting screws (M):
A:
LP Gas- The gas valve’s setting screws must be
tightened properly.
B:
Natural Gas- The gas valve’s setting screws must
finish flush with the fitting.
Make sure the flame does not go out and there are no
flashbacks when you turn the control knob between
the highest and lowest setting.
Never remove the valve stem. In the event of damage,
the gas valve must be completely replaced.
