Reset required after routine service

Greetings, I have a 20 yr old Milwaukee Thermo flow oil furnace. It was cleaned and tuned up a few days ago (new nozzle, new oil filter, etc). The tech was unsure which way the tank valve operates. Clockwise or counterclockwise to close, for filter change. In any case filter changed with some spillage. So he set the valve "halfway" when finished.

So in the past few days, the furnace stopped twice. I hit the reset and it started back up. I'm concerned that something is wrong as I never needed to reset before. Advice or ideas welcome.

That tank valve is called a Firomatic valve and is a safety valve with a lead insert where the valve stem is in case of fire the insert will melt and close the valve to stop the flow of oil. To open it all the way turn the wheel until the stem is fully up for proper oil flow. As you turn the wheel you will see the stem threads rising. If the wheel comes up and you can remove it you have gone the wrong way.

If that doesn't help then he could have set your electrodes wrong or something else he touched when setting up the burner.

Hope this helps a little.
