New Dometic hotwater heater problems

Finally took this mess to a Dometic authorized rv shop. They upped the gas pressure to 12.5 on the regulator, adjusted the air slide and then found the hot water was 180 degrees so replacing the parts that limit the high temperature . If you read Dometic reviews they have issues

My dealer showed me the heaters are coming with the gas chute caulked downward and the ignitor not in the middle. Once he adjusted those and replaced the 140 thermostat all is well.
