I have a Bradford White 199,999 BTU propane tankless water on my house. It is the only gas appliance I have. It has worked for 7 years. Occasionally the water would go cold during a shower and I would have to turn the water off and back on to restart the heater. This may be a clue, but is not my current issue.
Recently my 250 gallon tank sprung a leak and had to be replaced. I had it replaced with a smaller 100 lb tank. The same regulator and plumbing are used on the new tank. The new setup worked fine the first day. That night the temperature dropped from 70 to 40. The water heater stopped working. If I go outside and turn on hot water I can hear the flame start, feel a short puff of warm air from the vent, then it goes cold and I get a code 12 (flame failure).
Yesterday my gas man came and turned the regulator up to put out 13.5 inches water column. This is as high as the regulator goes, and what the unit calls for. This solved the issue at the moment. It was 60 degrees outside. That night the temperature dropped back to 40 - flame failure again. Is it possible that my regulator is on the verge of going bad and the temperature drop with cold weather is messing with it?
