Adjusting The Gas Valves - Bosch NGMP677UC Installation Manual

Adjusting the Gas Valves

Turn the control knobs to the lowest setting.
1.
Remove the control knobs from the gas valves and
2.
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.
