I read something about this a while back. This is part of my reason for wanting to use my old heater for a couple more years in addition to tankless coming down, I suspect some of these bugs will be worked out. Are you sure you have enough gas volume for the unit? The tech from the gas company said that some people who have installed these type heaters ave experienced problems because it demands more gas. If the volume isn't high enough the heater will shut down. He said since this has been discovered he has installed many increased capacity regulators on existing meters and the home owners have had to re plumb their gas lines. He said some installers were using a reducer coupling to convert the existing 1/2" gas line to 3/4" which also choked the new heater...if you haven't already, it might be worth investigating.
