I checked Oven unit and found flame sensor bad, gas fittings leaking, gas pressure at 55 IWC. I sealed the gas leaks and leak checked. Then I was able to adjust the gas pressure down to get the unit operational but his fuel supplier is going to come out to replace the regulator. Then adjusted the main line pressures and manifold pressure on the unit to 11 IWC. The customer will let us know if he needs anything else.
