I got a call from a customer that needed his glass replaced. I asked how it became broken and his voice changed from calm to irritated. He said his wife was playing with their 8yr daughter and her heard his wife say "Hey, listen to the funny sound it makes when you throw water on the fireplace glass." He heard sizzle, sizzle.......oh crap. Yup, he is still finding little pieces of glass.
I don't know if I'm going to be able to locate the glass because it is about 12 years old. I guess they may be getting a new DV gas fireplace.
