Maintaining tankless water heater

We have had a gas tankless water heater since Oct/2014. It is just the two of us. We have never done anything in terms of servicing/maintaining it. I was searching the web and there are several U-tube videos showing how to flush the system with vinegar (for an hour). We called the gas company and they provide a service to maintain the heater - which is pretty cheap - but they dismantle the heater to clean it and do not flush it.

Any comments/advice appreciated.
