Why is it that on that on a gas water heater with the exasust on the top, the pipe that takes it outside (or to the chiminey) seems to sit about an inch above the water heater (leaving a gap). It seems that anysort of breeze (esp. if it is a constant breeze like a fan or something) would make all the carbon monoxide go into the house instead of where it should be. It seems that the only time this would work would be when the air is perfectly still.
