First burn; Tarm way over temperature!

Tarm 140 with 850 gallon storage. Tank temp started at 47 degrees F at 3 pm yesterday. All was working fine, with draft fan shutting down at 175 degrees F. Filled with wood when I went to bed; 11:00 pm, tank temp 96 degrees F.

Got up this morning to check things. Tank temp is 104 degrees F. Draft fan not running. Tarm temp is at 212 degrees F. Circ to tank is running.

What's going on???

Things have greatly improved...

I had failed to open a ball valve that I put in to isolate my new install from the oil system, so I could pressure test and work without water in the pipes.

This forum has been a great resource. This install has taken 2 years, due to money, and other major projects that came along (new septic system) and other work. Sure I spent more on oil, but my boiler will last two years longer...

Thanks again,

My information says to set the high point of the boiler at 180. To be on the safe side, and to protect the EDPM liner, I've set the high at 175.
