<human>: This one actually happened a few hours ago..

Converted my Weber Spirit from LP to natural gas by changing the orifices. A buddy told me that natural gas coming into your house is already regulated, so I figure I'll just give it a shot without adding a pressure regulator.

Grill lights, all is seemingly good. I close the lid and watch the heat rise...fast! The temperature needle on the lid thermometer go past the 600F mark. I turned it down, determined to get some burgers grilled for dinner, and start googling regulators and am not paying very much attention. Temperature keeps rising until I hear a loud thud and see: 

This is my normal grilling spot on LP, which probably wasn't smart either. I was too close to the window for this extra hot grill I was operating. Regulator ordered, grill will be relocated.

Oh, and I'll call a glass guy on Monday :|

Provide a brief overview of the text.
<bot>: converted a gas grill without really knowing what I was doing. Cracked my dining room window by leaving the extra hot grill too close.
