Found unit off. Griddle burner valves need replaced, not lighting properly. Unable to measure gas pressure but unit may need regulator. Oven valve also needs replaced. Will order and return. 3/30/17 replaced regulator and locally purchased nipples. Unit needs t-stat, flange, and knob. Will order and return. 4/7/17 found unit off. Removed center t-stat, found the tee and supply lines both need to be removed behind manifold so they t-stat would fit. Installed new, turned on, calibrated, cycling at 350*
