You need to make sure that your gas line it the correct size. Most of the ones in Kingwood are too small so you would have to call a plumber to run a larger line from the meter into your attic, that's where it gets really expensive.
I have a friend that has one and had to relocate their washing machine. They had an LG front loader that when filling with water, would do so by adding a little water in every few seconds. This pulsing made the water heater thing there was a problem and it would shut itself off and they would have to go into the attic to reset it. 4951
