Does anyone have any info in a Petro Pac Boiler? I Assume its from the 1950s and was probably originally a steam system before it was converted to hot water. The Model Number is PPF 1260 and the Serial is "DJM" Firing Rate was 11.3 GPH and output was 1260 Mbh. Specifically, I'm trying to find out approximately how many gallons of water the vessel holds but am interested in any info really. I have some pics if necessary but none that are very meaningful. thanks in advance.

The misguided idea of converting steam systems to hot-water didn't get started until well after that boiler was made.

Petro later became a company called Space Conditioning (late 50s I think) Then became part of Dunham-Bush in the 60s until they closed down. I believe they sold that boiler for years with various name on it.

ODR means outdoor reset- varying the water temperature according to the heat load based on the outdoor temperature. The Tekmar control should be staging the boilers based on the heat requirements, so that would be an ODR control.
Mixing is where you run the boilers hot enough to keep them from condensing, and mix some return water with the hot water from the boilers so the rads will get only enough heat to satisfy the load based on outdoor temperature.
