Arrived at location on 2/6/22 - Went to light pilots and not getting gas through pilot. Checked gas pressure on manifold and had no pressure. Inspected quick disconnect and found in poor condition and not having proper functions anymore. Also found gas regulator not letting gas through. Replaced regulator and quick disconnect and now am able to light pilots and burners. Found thermostat control for far right burner stuck on and has no control. This will need to be replaced. Also found knobs worn, broken and missing. Will obtain replacement thermostat and knobs and return. Unit functions at this time and ok for use.

Put on 4 new knobs. Could not collect payment. Completed.
